Mazur, AI, and the Future of Legal Support | JSH Law

The legal landscape is shifting in two powerful directions at once. On one hand, the High Court decision in Mazur v Charles Russell Speechlys LLP has reinforced the boundaries around who can legally conduct litigation. On the other, artificial intelligence is rapidly expanding what litigants in person are capable of achieving without formal representation. These developments are not in conflict—they are converging. Together, they are reshaping the future of legal support into something more structured, more transparent, and ultimately more empowering for those navigating the system themselves.

Mazur, AI, and the Future of Legal Support | JSH Law
Key Takeaways
  • Mazur reinforces that conduct of litigation must remain with authorised or exempt individuals.
  • AI does not replace the litigant — it enhances their ability to run their case.
  • The future of legal support lies in structured, transparent, tech-enabled models.
  • Litigants in person can become more capable, not more dependent.
  • The combination of AI and proper legal structure will redefine access to justice.

Mazur, AI, and the Future of Legal Support

The legal system is entering a period of change that is both structural and technological.

On one side, the High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB) has reinforced the boundaries of who can legally conduct litigation. On the other, the rapid development of artificial intelligence is transforming how legal work is prepared, structured, and delivered.

At first glance, these developments may appear to be in tension.

One restricts who can carry out certain legal functions. The other expands who can access tools that were once limited to professionals.

In reality, they are moving in the same direction.

Towards a legal system where structure, transparency, and capability matter more than ever.

The Reinforcement of Legal Boundaries

The significance of Mazur lies not in creating new law, but in clarifying how existing law is to be applied.

The decision reinforces a simple but important principle:

The conduct of litigation is a reserved activity. It cannot be delegated simply through supervision or informal arrangements.

This draws a clear boundary around who can formally run a case.

For litigants in person, that boundary is not a barrier—it is a framework.

It confirms that the case is, and remains, theirs.

The Rise of AI in Legal Support

At the same time, artificial intelligence is rapidly changing how legal work is done.

Tasks that once required significant time and expertise can now be supported by systems that:

  • Analyse large volumes of documents
  • Structure arguments and chronologies
  • Assist with drafting and refinement
  • Identify gaps and inconsistencies

These tools are not theoretical.

They are already being used across the legal sector, from large firms to individual practitioners.

The question is not whether AI will play a role in legal support.

It is how that role is defined.

AI Does Not Conduct Litigation

This is where the alignment between Mazur and AI becomes clear.

AI does not “conduct litigation”.

It does not make decisions, take responsibility, or act on behalf of a party in a legal sense.

What it does is enhance capability.

It enables:

  • Better preparation
  • Clearer structure
  • More efficient organisation

Used properly, AI sits firmly within the category of support.

It strengthens the litigant’s ability to run their own case, rather than replacing them.

A Shift From Representation to Enablement

Traditionally, legal services have been built around representation.

A solicitor or barrister takes conduct of the case and acts on behalf of the client.

For many litigants in person, that model is not accessible.

What is emerging instead is a different model.

One based on enablement.

In this model:

  • The litigant remains in control
  • Support is provided to enhance capability
  • Technology is used to improve structure and clarity

This is not a second-tier alternative.

It is a distinct and increasingly important part of the legal ecosystem.

The Risk of Getting It Wrong

As with any shift, there are risks.

AI, if misunderstood, can create the same problems as poorly structured human support.

If it is used in a way that removes the litigant from decision-making, or creates a sense that the case is being “run externally”, then the underlying issue remains.

The tool itself is not the risk.

How it is used is what matters.

The Opportunity for Litigants in Person

For litigants in person, this moment presents a significant opportunity.

With the right approach, it is now possible to:

  • Prepare cases to a higher standard
  • Organise evidence more effectively
  • Present arguments with greater clarity

Without stepping outside the boundaries of the law.

This is not about replacing legal professionals.

It is about increasing the capability of those who are navigating the system themselves.

A More Structured Future

The combined effect of Mazur and AI is likely to lead to a more structured approach to legal support.

We can expect to see:

  • Clearer definitions of roles
  • More transparent support models
  • Greater emphasis on litigant control

At the same time, the tools available to litigants will continue to improve.

This creates a system that is both more disciplined and more accessible.

Where This Leaves Legal Professionals

For legal professionals, this shift is not a threat—it is a redefinition.

There will always be a need for authorised representation.

But alongside that, there is a growing space for:

  • Strategic support
  • Case structuring
  • Technology-enabled assistance

Those who understand this shift are likely to play a key role in shaping the future of legal services.

Final Thoughts

The legal system is not standing still.

Mazur reinforces the boundaries of who can formally conduct litigation.

AI expands the tools available to those who cannot access traditional representation.

Together, they point towards a future where:

Litigants in person are not left behind — but are better equipped, better supported, and more capable than ever before.

The key is structure.

Get that right, and both law and technology work in your favour.

How to Stay Safe as a Litigant in Person After Mazur (Step-by-Step Guide) | JSH Law

If you are a litigant in person, the way your case is structured now matters more than ever. Following the High Court decision in Mazur v Charles Russell Speechlys LLP, the court has made it clear that only authorised or exempt individuals can conduct litigation—and that line is being looked at more closely in practice. The result is that many people, often without realising it, may be exposing their case to unnecessary risk simply through how it is being handled. The good news is that this is entirely manageable. With the right structure in place, you can stay fully compliant, protect your position, and strengthen your case at the same time.

How to Stay Safe as a Litigant in Person After Mazur (Step-by-Step Guide) | JSH Law
Key Takeaways for Litigants in Person
  • You must remain in control of your case at all times.
  • Support is allowed — but it must not become “conduct of litigation”.
  • The court is increasingly alert to who is actually running the case.
  • Clear structure protects your credibility and your position.
  • Simple procedural discipline can eliminate most risks.

How to Stay Safe as a Litigant in Person After Mazur (Step-by-Step Guide)

If you are a litigant in person, you are already carrying a significant responsibility.

You are managing your own case, navigating court procedure, and making decisions that may have long-term consequences for you and your family.

Following the High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB), there is now an additional layer to that responsibility:

You must not only run your case — you must be seen to be running it.

This is where many people unintentionally expose themselves to risk.

This guide sets out, in practical terms, how to stay safe, compliant, and in control — while still getting the support you need.

Step 1: Understand the One Rule That Matters

Everything in this area comes back to a single principle:

You are the one conducting your case.

That means:

  • You make the decisions
  • You give the instructions
  • You take responsibility for what is filed and said

This is not about doing everything alone.

It is about ensuring that, at every stage, it is clear that the case is yours.

If that is maintained, you are on solid ground.

Step 2: Separate “Support” from “Control”

The most common mistake litigants make is confusing support with control.

Support is allowed — and often essential.

Control must remain with you.

To make this clear, apply this simple test:

“Am I the one making the decision and taking the step?”

If the answer is yes, you are within the correct structure.

If the answer is unclear, that is where risk begins.

For example:

  • If someone drafts a document for you → that is support
  • If someone decides what goes in that document → that may be control
  • If someone sends the document on your behalf → that may cross the line

The difference is subtle, but important.

Step 3: Take Ownership of Every Document

Every document in your case should be something you can stand behind.

That means:

  • You have read it
  • You understand it
  • You agree with it

In practical terms:

  • Do not submit anything you have not reviewed carefully
  • Do not rely on “it’s been handled”
  • Do not allow documents to be sent without your approval

Your name is on the case. The responsibility follows it.

Step 4: You Send the Emails

This is one of the simplest and most important safeguards.

All communications with:

  • The court
  • The other party
  • Solicitors

should be sent by you.

Support can help you draft those emails.

But you should be the one pressing send.

This ensures that:

  • Your role is clear
  • Your control is visible
  • Your position cannot be easily challenged

It also reinforces your credibility as a litigant in person.

Step 5: You Sign and File Everything

This is non-negotiable.

All documents:

  • Statements
  • Position statements
  • Applications

must be:

  • Signed by you
  • Filed by you

This is not just procedural.

It is a clear marker of who is conducting the case.

Where that marker is missing, questions can arise.

Step 6: Maintain a Clear Audit Trail

If your case were examined closely, you should be able to show:

  • That you made decisions
  • That you approved documents
  • That you gave instructions

This does not require complex systems.

It can be as simple as:

  • Email confirmations
  • Document versions showing your approval
  • Clear communication records

The aim is clarity.

If it is clear that you are in control, your position is protected.

Step 7: Be Careful Who You Rely On

Not all support is structured in the same way.

Some models are careful to remain within the boundaries of support.

Others may move closer to running the case, sometimes without clearly recognising the distinction.

This is not always obvious at the outset.

But you should be alert to signs such as:

  • Someone taking over communications
  • Decisions being made without your input
  • A sense that the case is being “handled” for you

These are indicators that the structure may need to be corrected.

Step 8: Understand How the Court Sees It

The court is not concerned with internal arrangements.

It looks at what is visible.

From the court’s perspective, the key question is simple:

Who appears to be running this case?

If the answer is clearly you, there is no issue.

If the answer is unclear, the court may take a closer look.

Clarity removes that risk entirely.

Step 9: Do Not Lose Your Voice in Your Own Case

One of the unintended consequences of over-reliance on support is that litigants can lose confidence in their own voice.

This can show in:

  • Hesitation in court
  • Uncertainty about their own position
  • Difficulty responding to questions

Staying in control of your case avoids this.

It ensures that:

  • You understand your arguments
  • You can explain your position
  • You remain engaged with the process

This is not just legally important.

It is strategically important.

Step 10: Use Support Properly — and Powerfully

The answer to all of this is not to avoid support.

It is to use it properly.

When structured correctly, support can:

  • Strengthen your case
  • Improve your preparation
  • Increase your confidence
  • Enhance how your case is presented

But it should always operate behind your role — not replace it.

You remain the decision-maker. Support strengthens you, not substitutes you.

Step 11: Recognise the Red Flags Early

One of the most effective ways to protect your case is to recognise when the structure is beginning to drift.

This rarely happens suddenly. It is usually gradual.

Support becomes more involved. Communication becomes more direct. Decisions start to feel less like yours and more like something being done “for you”.

That is the point at which you need to pause and reassess.

Common red flags include:

  • Emails being sent without your direct involvement
  • Documents being finalised without your review
  • Instructions being given on your behalf
  • A sense that you are being told what will happen, rather than deciding it

None of these, in isolation, automatically creates a problem.

But taken together, they can indicate that the structure of your case is no longer clear.

Clarity is what protects you. Loss of clarity is what creates risk.

Step 12: Real-World Scenario — Where Things Go Wrong

To understand how easily this can happen, consider a common scenario.

A litigant in person is overwhelmed. They engage someone to help. That person is experienced and confident. They begin by assisting with drafting. Then they begin to suggest wording. Then they begin to take a more active role in communication.

At first, this feels helpful.

Over time, however, the balance shifts.

The litigant becomes less involved in the detail. Documents are trusted without being fully reviewed. Emails are sent quickly to “keep things moving”.

From the outside, it may now appear that the case is being run by someone else.

This is not usually intentional.

But intention is not the test.

What matters is how the case is being conducted in practice.

Step 13: The “Safe Structure” Checklist

If you want to be confident that your case is properly structured, use this checklist.

You should be able to answer “yes” to all of the following:

  • I make the final decisions in my case
  • I review and approve every document before it is sent
  • I send all emails in my own name
  • I sign all statements and applications personally
  • I understand the key points being made in my case
  • I can explain my position to the court

If any of these answers are “no”, that is an opportunity to bring the structure back into line.

This is not about blame.

It is about clarity and control.

Step 14: Common Mistakes to Avoid

There are a number of recurring mistakes that litigants make, particularly when under pressure.

These include:

1. Delegating decisions
Allowing someone else to decide what should be said or done without your full involvement.

2. Not reviewing documents properly
Signing or sending documents without fully understanding their content.

3. Allowing others to communicate on your behalf
This is one of the clearest ways the line can be crossed.

4. Becoming disengaged from the case
Relying too heavily on support can reduce your own understanding and confidence.

Each of these is understandable.

But each can also weaken your position if not addressed.

Step 15: How This Strengthens Your Case — Not Just Protects It

It is important to recognise that these steps are not simply about avoiding problems.

They actively improve your case.

When you are clearly in control:

  • Your credibility with the court increases
  • Your submissions are more coherent
  • Your responses are more confident
  • Your case is more resilient to challenge

Judges are used to dealing with litigants in person.

What they look for is clarity, engagement, and understanding.

A well-structured case demonstrates all three.

Step 16: Confidence Comes From Control

Many litigants assume that confidence comes from having someone else take over.

In reality, the opposite is true.

Confidence comes from understanding your case and being able to explain it.

That only happens when you remain actively involved.

Support should increase your confidence, not replace your role.

Step 17: The Strategic Advantage Most People Miss

There is a misconception that staying within these boundaries limits what you can do.

In practice, it creates an advantage.

When your case is structured properly:

  • There is less room for procedural attack
  • Your position is clearer and more focused
  • The court can engage directly with you

At the same time, you still benefit from support behind the scenes.

This combination—control at the front, structure behind—can be extremely effective.

Step 18: A Final Word on Balance

This is not about drawing rigid lines that make your case harder to manage.

It is about balance.

You should not feel that you are facing proceedings alone.

But equally, you should not feel that your case is being taken out of your hands.

The correct position sits between those two points.

You are supported, but you remain in control.

Final Thoughts

The decision in Mazur has brought clarity to an area that many people did not fully consider.

For litigants in person, that clarity is an opportunity.

It allows you to structure your case in a way that is:

  • Compliant
  • Robust
  • Credible

Most importantly, it ensures that your case is judged on what matters:

The facts, the evidence, and the outcome you are seeking.

Get the structure right, and everything else becomes stronger.

The Unregulated Legal Support Market Is Changing – And Not Everyone Will Survive Mazur | JSH Law

For years, the unregulated legal support market has operated in a space shaped more by necessity than structure. As increasing numbers of litigants in person entered the family courts, support services evolved to fill a widening gap—often quickly, and not always with clearly defined boundaries. The High Court decision in Mazur v Charles Russell Speechlys LLP marks a turning point. It does not change the law, but it does change how closely that law is now being examined in practice. The result is a shift that will not affect everyone equally—and not every model will survive it.

The Unregulated Legal Support Market Is Changing – And Not Everyone Will Survive Mazur | JSH Law
Key Takeaways
  • The unregulated legal support market is entering a period of increased scrutiny.
  • The distinction between support and conduct of litigation is now central.
  • Models that blur this line are likely to face challenge.
  • Structured, transparent support models will become the standard.
  • This shift will reshape access to justice, not remove it.

The Unregulated Legal Support Market Is Changing – And Not Everyone Will Survive Mazur

For years, the unregulated legal support market has operated in a space that was, if not undefined, then at least loosely interpreted in practice.

That space emerged out of necessity. As the number of litigants in person increased—particularly in the family courts—the demand for accessible, affordable support grew with it. In response, a wide range of support models developed, from informal assistance through to highly structured services.

Some of those models have provided genuine value. Others have blurred lines that were always present in law but not always enforced in practice.

The High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB) signals that this period of ambiguity is coming to an end.

The question is no longer whether the line exists. It is whether it is being respected.

A Market Built on Demand

To understand the significance of this shift, it is necessary to understand how the current landscape developed.

Over the past decade, the reduction in legal aid and the increasing cost of private representation have resulted in a substantial rise in litigants in person. In family proceedings, this is no longer the exception—it is the norm.

Where demand exists, supply follows.

The result has been the growth of an unregulated support sector, offering services that range from basic administrative help to full-scale case preparation.

In many instances, these services have filled a critical gap.

But the absence of clear structural boundaries has also led to inconsistency in how those services are delivered.

The Legal Position Was Always Clear

It is important to be precise about one point.

The legal framework has not changed.

The Legal Services Act 2007 has always made clear that “conduct of litigation” is a reserved legal activity. Only authorised or exempt individuals are permitted to carry it out.

What has changed is the level of attention being given to that distinction.

The decision in Mazur reinforces a strict interpretation of the law and, more importantly, signals that the courts are prepared to look beyond labels and examine what is actually happening in practice.

This is a shift from form to substance.

From Labels to Reality

For some time, the terminology used within the unregulated sector has allowed for a degree of flexibility.

Terms such as “support”, “assistance”, or “case help” can describe a wide range of activity.

The issue is that the law is not concerned with terminology. It is concerned with function.

If a person is, in substance, making decisions, managing the case, and acting on behalf of the litigant, then the question becomes whether they are conducting litigation—regardless of how their role is described.

This is where the impact of Mazur is most significant.

The focus is now on what is being done, not what it is called.

What This Means for the Sector

This shift is likely to have a filtering effect on the market.

Models that are clearly structured, transparent, and compliant with the legal framework are likely to adapt and continue.

Models that rely on blurred boundaries may find themselves under increasing pressure.

This pressure may come from multiple directions:

  • Opposing parties raising procedural challenges
  • Courts scrutinising the role of those involved in a case
  • Increased awareness among litigants themselves

Over time, this is likely to lead to a more defined and professionalised support landscape.

The Risk of Misinterpretation

There is, however, a risk that this development is misunderstood.

It would be easy to interpret Mazur as a restriction on support for litigants in person.

That would be the wrong conclusion.

The need for support has not diminished. If anything, it has increased.

The issue is not whether support should exist.

It is how that support is structured.

Well-structured support enhances access to justice. Poorly structured support can undermine it.

A Turning Point for Professional Standards

This moment represents an opportunity as much as a challenge.

For those operating within the unregulated sector, it creates a clear incentive to:

  • Define their role precisely
  • Ensure that litigants remain in control of their cases
  • Operate transparently and consistently

In doing so, the sector has the potential to evolve.

From a loosely defined collection of services into a more structured, credible, and trusted component of the justice system.

The Future of Legal Support

Looking ahead, the likely trajectory is not the disappearance of unregulated support, but its refinement.

We are likely to see:

  • Clearer distinctions between support and representation
  • More structured service models
  • Greater awareness among litigants of their own role and responsibility

This aligns with a broader trend within the legal system.

One in which accessibility, transparency, and accountability are becoming increasingly central.

Final Thoughts

The unregulated legal support market was shaped by necessity.

It is now being shaped by scrutiny.

The decision in Mazur does not close the door on support.

It defines the terms on which that support can operate.

Those who adapt to that structure will continue to provide value. Those who do not may find that the space they have relied upon no longer exists in the same way.

This is not the end of the sector.

It is the beginning of a more defined one.

Structured Support That Works With the Law

McKenzie Friend vs Running Your Case: Where the Legal Line Now Sits After Mazur

There has always been a quiet grey area in the family courts around what a McKenzie Friend actually does in practice. Many litigants in person rely heavily on support, and in some cases that support can become so involved that it begins to look like the case is being run for them. Following the High Court decision in Mazur v Charles Russell Speechlys LLP, that grey area has now been brought into sharp focus. The court has made it clear that there is a legal boundary between supporting a case and conducting it—and understanding that boundary is now essential for anyone navigating proceedings without a solicitor.

McKenzie Friend vs Running Your Case: Where the Legal Line Now Sits | JSH Law Legal consultation and court paperwork discussion
Key Takeaways for Litigants in Person
  • A McKenzie Friend provides support — they do not run your case.
  • Only authorised or exempt individuals can conduct litigation.
  • The key legal test is who is in control of the case.
  • Crossing the line can expose your case to challenge.
  • Structured support strengthens your position; loss of control weakens it.

McKenzie Friend vs Running Your Case: Where the Legal Line Now Sits

There has always been a degree of confusion around the role of a McKenzie Friend.

For many litigants in person, the distinction feels blurred. You have support. That support may be experienced, knowledgeable, and heavily involved in your case. In practical terms, it can sometimes feel as though that person is “handling things” for you.

But following the High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB), that distinction is no longer something that can be left unclear.

The law draws a firm line between supporting a case and conducting it.

Understanding where that line sits is now essential.

The Role of a McKenzie Friend — What It Is Meant to Be

The role of a McKenzie Friend is well established in the courts of England and Wales. It exists to support litigants in person, particularly in complex or emotionally demanding proceedings such as family cases.

At its core, the role is supportive.

A McKenzie Friend may:

  • Assist with preparing documents
  • Help organise evidence
  • Provide guidance on procedure and strategy
  • Take notes during hearings
  • Offer quiet assistance in court

In some circumstances, and only with the court’s permission, they may also be allowed to address the court.

But even then, the underlying position does not change:

The litigant remains in control of their case.

What “Running the Case” Actually Means

This is where the distinction becomes critical.

Running a case—legally described as “conducting litigation”—goes beyond support. It involves:

  • Making decisions about how the case progresses
  • Sending correspondence on behalf of the party
  • Managing filings and procedural steps
  • Taking responsibility for how the case is conducted

These are not simply administrative tasks. They are the core functions of legal representation.

Under the Legal Services Act 2007, they are reserved to authorised or exempt individuals.

This is the line that Mazur has brought back into sharp focus.

Why This Line Matters Now More Than Ever

For years, there has been a degree of practical flexibility in how cases are supported, particularly where litigants in person are concerned.

That flexibility has, in some areas, led to roles becoming blurred.

The decision in Mazur does not introduce a new rule. What it does is reinforce the existing one—and signal that it will be taken seriously.

The courts are now more alert to:

  • Who is actually making decisions
  • Who is sending communications
  • Who appears to be in control of the case

If the answer is not the litigant, questions may arise.

The Practical Difference — Control

The easiest way to understand the distinction is this:

A McKenzie Friend supports your case. They do not control it.

In a properly structured case:

  • You decide what to do
  • You approve every document
  • You send communications in your own name
  • You take responsibility for the case

Support sits behind that process, not in place of it.

Where that structure is clear, there is no difficulty.

Where it is not, that is where risk begins.

How the Line Gets Crossed (Often Without Realising)

In practice, the line is rarely crossed deliberately.

It tends to happen gradually.

A litigant feels overwhelmed. Someone steps in to “help more”. That help becomes more hands-on. Decisions start being made. Emails start being sent. The case begins to feel as though it is being handled by someone else.

At that point, the structure has shifted.

What began as support may now look, from the outside, like conduct.

And it is how it appears externally that matters.

Why This Can Affect Your Case

If the distinction is not maintained, the issue is not simply theoretical.

It can become a point of challenge.

The other side may argue:

  • That your case has not been properly conducted
  • That procedural steps are open to question
  • That your position should be treated with caution

Even if those arguments do not ultimately succeed, they can create distraction, delay, and pressure.

In litigation, that matters.

The Strongest Position You Can Be In

The strongest position is one where the structure of your case is clear, transparent, and beyond challenge.

That means:

  • You are visibly in control
  • Your decisions are your own
  • Your documents reflect your position
  • Your case is supported, but not run by someone else

This does not weaken your case.

It strengthens it.

A Better Way to Think About Support

The most effective support model is not one where someone takes over.

It is one where you are equipped.

Where:

  • Your case is structured properly
  • Your evidence is organised clearly
  • Your arguments are prepared carefully
  • You understand what you are doing and why

That is what good support looks like.

It is not about removing your role.

It is about strengthening it.

Final Thoughts

The distinction between a McKenzie Friend and someone running a case has always existed.

What Mazur has done is make it impossible to ignore.

Support is allowed. Conduct is restricted. Control must remain with the litigant.

Once that is understood and properly structured, the position becomes clear—and your case becomes stronger for it.

Could Your Case Be Invalid? The Hidden Risk After Mazur

Most litigants in person focus on the evidence in their case—what happened, what can be proven, and what outcome they are asking the court to make. But following the High Court decision in Mazur v Charles Russell Speechlys LLP, there is another issue that is now just as important: who is actually running your case. If that line is blurred, it can create risks that go beyond the facts themselves—affecting how your case is viewed, how it is challenged, and ultimately how strong your position really is.

Could Your Case Be Invalid? The Hidden Risk After Mazur | JSH Law
Key Takeaways for Litigants in Person
  • If someone else is effectively running your case, it may create legal risk.
  • Only authorised or exempt individuals can conduct litigation.
  • The court is increasingly alert to who is actually in control of a case.
  • Opponents may use this issue tactically against you.
  • You must remain visibly and practically in control at all times.

Could Your Case Be Invalid? The Hidden Risk After Mazur

Most litigants in person are focused on the facts of their case.

What happened. What the evidence shows. What outcome they are asking the court to make.

But following the High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB), there is another issue that cannot be ignored:

Who is actually running your case?

Because if the answer is “not you”, there may now be risks that many people simply haven’t considered.

Why This Issue Matters More Than Ever

The court in Mazur made it clear that “conduct of litigation” is a reserved legal activity. Only authorised or exempt individuals can carry it out.

This is not new law.

What has changed is how clearly—and how strictly—the courts are now prepared to apply it.

That means the question of who is in control of a case is no longer just technical. It can become a live issue.

What Could Go Wrong?

If someone else is effectively running your case—making decisions, sending correspondence on your behalf, or managing the process—you may face:

  • Challenges from the other side about how your case has been conducted
  • Increased scrutiny from the court
  • Arguments that your case has not been properly managed

This does not automatically mean your case is “invalid”.

But it does mean that your position may be more open to challenge than you expect.

The Tactical Reality

Family proceedings are often hard-fought.

Where an opportunity exists to challenge the other party’s position, it is often taken.

Following Mazur, one such line of challenge may be:

“This case has not been conducted properly.”

Even raising that argument can:

  • Shift focus away from your core case
  • Create additional pressure
  • Undermine how your case is perceived

That is a risk worth managing carefully.

The Most Common Misunderstanding

Many litigants assume that as long as they have help, they are protected.

That is not the test.

The test is control.

Are you the one making the decisions and taking the steps in your case?

If the answer is unclear, that is where problems can begin.

What a Safe Structure Looks Like

A properly structured case will always show that:

  • You make the decisions
  • You approve all documents
  • You send communications in your own name
  • You sign and file everything

Support can sit behind that.

It can be strong, detailed, and strategic.

But it must remain support.

Red Flags to Watch For

If any of the following are happening, it is worth stepping back and reassessing:

  • Someone else is emailing the court or the other side on your behalf
  • Documents are being sent without your clear approval
  • Decisions are being made “for you”
  • You feel like you are not fully in control of your case

These are not just practical concerns—they may now carry legal significance.

Staying in Control Strengthens Your Case

This is not just about avoiding risk.

When you are clearly in control of your case:

  • Your credibility improves
  • Your position is harder to challenge
  • Your case presentation becomes more coherent

Structure is not a limitation.

It is an advantage.

Final Thoughts

The decision in Mazur does not mean you should face proceedings alone.

It means that how your support is structured now matters more than ever.

The strongest position is one where you are clearly in control, supported by the right structure behind you.

Get that right, and your case remains focused where it should be—on the outcome for you and your family.

Mazur Explained: The Case That Changes Who Can Run Your Court Case | JSH Law

The High Court has just drawn a firm line around who is actually allowed to run a court case—and it’s a line many people have been crossing without realising. In Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB), the court made it clear that only authorised or exempt individuals can conduct litigation, and that supervision is not enough. For litigants in person, this is not just a technical legal point—it goes directly to how your case is handled, how it is perceived by the court, and whether your position is open to challenge.

Key Takeaways for Litigants in Person
  • Only authorised or exempt individuals can legally conduct litigation.
  • Even well-meaning support can cross the line if someone starts running your case.
  • You must remain in control of your case at all times.
  • Getting this wrong can expose your case to challenge or criticism.
  • Structured, compliant support can strengthen your position significantly.

Mazur Explained: The Case That Changes Who Can Run Your Court Case

There has been a significant shift in how the courts are approaching who is actually allowed to run a case.

The High Court decision in Mazur v Charles Russell Speechlys LLP [2025] EWHC 2341 (KB) has clarified something that, until now, many people in the legal world had quietly blurred:

Only certain people are legally allowed to conduct litigation — and supervision is not enough.

For litigants in person, this matters more than you might realise.

What Happened in Mazur?

The case arose from a situation where work on a legal matter had been carried out by someone who was not an authorised solicitor or exempt person, but who was working within a legal environment.

The argument was that because this individual was supervised, their actions were acceptable.

The High Court disagreed.

The judgment made it clear that:

  • “Conduct of litigation” is a reserved legal activity under the Legal Services Act 2007
  • Only authorised or exempt individuals can carry it out
  • Supervision by a solicitor does not make an unauthorised person compliant

This was not a new rule — but it is now being applied much more strictly.

What Does “Conduct of Litigation” Actually Mean?

This is the critical question.

It does not just mean standing up in court. It includes:

  • Making decisions about how the case is run
  • Sending correspondence on behalf of a party
  • Filing documents
  • Taking responsibility for procedural steps

In simple terms:

If someone else is effectively running your case — they may be conducting litigation.

Why This Matters for Litigants in Person

Many litigants in person rely on support. That support can be incredibly valuable — and in many cases, essential.

But there is now a much sharper line between:

  • Support (which is allowed), and
  • Conduct (which is restricted)

If that line is crossed, it can lead to:

  • Challenges from the other side
  • Increased scrutiny from the court
  • Questions about how the case has been handled

This is not about creating fear — it is about understanding how to stay on solid ground.

The Difference Between Support and Running the Case

A properly structured support model looks like this:

  • You make the decisions
  • You send the emails
  • You sign and file the documents
  • You speak for yourself in court

Support can include:

  • Drafting documents for you
  • Helping you prepare your case
  • Advising you on strategy
  • Assisting you in court as a McKenzie Friend

The key distinction is control.

You must remain in control of your case at all times.

What This Means in Practice

If you are receiving support, you should always be able to say:

  • “I reviewed and approved this document”
  • “I chose to send this”
  • “These are my instructions”

That clarity protects you.

It also strengthens your credibility in court.

A Shift in the Legal Landscape

This decision reflects a wider shift.

The courts are becoming more alert to:

  • Who is actually running a case
  • Whether the proper boundaries are being respected
  • How unregulated support is being used

At the same time, the reality remains:

Access to justice increasingly depends on litigants in person having the right support.

The answer is not less support.

It is better-structured support.

Final Thoughts

Mazur does not remove your ability to get help.

What it does is make one thing very clear:

There is a right way to do this — and a wrong way.

If your case is structured properly, support can be a powerful advantage.

If it is not, it can become a vulnerability.

Understanding that distinction is now essential.
