Non-Fatal Strangulation: Why Family Courts Must Treat It as a Lethal Risk Warning

Non-fatal strangulation is one of the most dangerous warning signs in domestic abuse and intimate partner violence. It is not “just another assault”. It is not “rough handling”. It is not something that should be minimised because there is no visible injury. It is a high-risk indicator that may show the situation has already escalated towards lethal danger.

This article was prompted by a LinkedIn article by Robert Kaiser, Founder & Executive Chairman of PPSS Group, Founder of the Women’s Safety Institute, and PhD researcher in criminology focusing on Escalation Pattern Analysis in intimate partner violence. His article, Non-Fatal Strangulation: A Critical Warning Sign of Lethal Risk in Intimate Partner Violence, discusses his peer-reviewed paper, Escalation Pattern Analysis in Nonfatal Strangulation: Lethality Risk and Safeguarding in Intimate Partner Violence, published in Partner Abuse.

Kaiser’s core point is stark: non-fatal strangulation is not merely an incident to record. It is a critical warning sign of escalation. His work argues that risk assessment must move beyond a simple yes-or-no question and instead examine the pattern, context, repetition, intensity and trajectory of abuse.

For litigants in person in the family court, that point matters enormously.

Because if non-fatal strangulation is misunderstood, minimised or treated as one allegation among many, the court may fail to recognise the level of risk. That can affect child arrangements, interim contact, fact-finding decisions, police disclosure, Cafcass recommendations, safety planning and the survivor’s ability to protect themselves and the children.

Non-Fatal Strangulation Is Not a Minor Assault

In England and Wales, non-fatal strangulation and suffocation became a specific criminal offence under section 70 of the Domestic Abuse Act 2021, which inserted section 75A into the Serious Crime Act 2015. The offence came into force on 7 June 2022.

The Crown Prosecution Service guidance on strangulation and suffocation makes clear that the offence is not limited to domestic abuse cases. It should be considered wherever there is evidence of strangulation or suffocation. However, in domestic abuse cases, it often sits within a wider pattern of coercive control, intimidation and escalating violence.

The Government described the offence as aimed at abusers who strangle partners in order to control or induce fear, with perpetrators facing up to five years in prison. That recognition was long overdue.

Before the specific offence was introduced, non-fatal strangulation was too often charged as a lower-level assault, even where the behaviour was terrifying, controlling and potentially lethal. One of the reasons this happened was because visible injuries may be absent or minimal.

That is precisely why this issue is so dangerous.

If professionals rely on bruises, marks or visible injury as the main proxy for seriousness, they can miss one of the clearest warning signs of lethal risk.

The absence of visible injury is not evidence that strangulation was not serious. It may be evidence that the system is looking for the wrong thing.

Why Strangulation Is So Dangerous

Non-fatal strangulation is dangerous because it directly interferes with breathing, blood flow or oxygen supply. Survivors often describe it as the moment they believed they were going to die.

That fear is not overreaction.

It reflects the reality of what is happening to the body.

Pressure to the neck can affect breathing, blood vessels, nerves, the brain, the voice, swallowing and consciousness. Loss of consciousness can happen quickly. Serious injury can occur internally even where the skin does not show obvious injury.

The Institute for Addressing Strangulation works to improve professional awareness of the risks associated with strangulation and suffocation. Its professional guidance emphasises that non-fatal strangulation should be taken seriously as both a medical and safeguarding issue.

Healthcare and safeguarding responses must therefore avoid the dangerous assumption that “no marks” means “no harm”.

Some symptoms may not appear immediately. Survivors may experience difficulty swallowing, voice changes, breathing difficulties, dizziness, memory problems, confusion, headaches, neck pain, incontinence, loss of consciousness, psychological trauma or neurological symptoms. Some survivors may not understand the medical significance of what happened to them. Others may minimise it because they are frightened, ashamed, traumatised or still under the control of the perpetrator.

That is why any disclosure of strangulation should be treated as urgent.

In an emergency, or where there are symptoms such as breathing difficulty, difficulty swallowing, weakness, confusion or worsening symptoms, medical help should be sought immediately.

The Family Court Problem: Strangulation Gets Treated as an Incident

The family court often works by allegations. A Scott Schedule may list one incident per row. A witness statement may divide events into dates. A Cafcass report may summarise “allegations made by the mother” and “denials by the father”.

That structure can be useful.

But it can also flatten risk.

Non-fatal strangulation should not be treated as merely one entry in a list of allegations. It should make the court pause and ask a different set of questions.

What happened before the strangulation?

Was there a pattern of coercive control?

Were there earlier threats?

Was there stalking, harassment, sexual violence, isolation, financial control or intimidation?

Was the incident connected to separation, pregnancy, contact disputes, jealousy, perceived loss of control or litigation?

Was it accompanied by threats such as “I’ll kill you”, “you won’t wake up next time”, or “no one will believe you”?

Was the pressure increasing?

Had the behaviour happened before?

Was there a pattern of remorse reducing over time?

Was the survivor’s fear increasing?

Did the children see, hear or experience the aftermath?

Those questions matter because domestic abuse is rarely a random collection of disconnected incidents. It is often a pattern.

And in coercive control cases, the pattern is the point.

Robert Kaiser’s Point: From Incidents to Escalation

Robert Kaiser’s work on Escalation Pattern Analysis is helpful because it challenges the limitations of incident-based thinking.

In the article that prompted this blog, Kaiser explains that risk assessment often records whether strangulation has occurred as a binary variable: yes or no. That is important, but insufficient. A yes-or-no answer tells us that the event happened. It does not tell us enough about the trajectory of the abuse.

His Escalation Pattern Analysis framework focuses on three dimensions:

• Frequency: how often abusive behaviours occur and whether the gaps between them are shortening;
• Intensity: whether the behaviours are becoming more severe, intrusive, frightening or potentially lethal;
• Inhibitory decline: whether the perpetrator appears to be showing reduced restraint, increased entitlement, greater volatility or less concern about consequences.

That framework is highly relevant to family court.

A litigant in person may know that something is escalating but struggle to explain it in legal terms. They may say “it got worse” or “I knew something had changed” or “I felt he was capable of killing me”. Professionals may dismiss that as subjective fear unless the evidence is properly organised.

Escalation analysis gives language to what survivors often experience before the system catches up.

It helps the court see not only what happened, but where the behaviour appears to be going.

In family court, the question should not be only “did strangulation happen?” The question should be “what does this reveal about the pattern, trajectory and risk?”

Why Visible Injury Is the Wrong Test

One of the most dangerous myths about non-fatal strangulation is that it must leave obvious marks.

It often does not.

The SafeLives non-fatal strangulation training materials highlight that non-fatal strangulation can be difficult to evidence because of a lack of visible injury and that professionals need to understand its link with domestic abuse and sexual violence.

For family court purposes, this matters because respondents may say:

• “There were no bruises.”
• “She did not go to hospital.”
• “There is no medical evidence.”
• “She is exaggerating.”
• “It was consensual.”
• “It was just a heated argument.”
• “If it was serious, she would have reported it immediately.”

Those arguments can be powerful if the court does not understand non-fatal strangulation properly.

A survivor may not report immediately because they are frightened. They may not seek medical help because they do not realise there could be internal injury. They may be under coercive control. They may fear losing the children. They may have been told no one will believe them. They may have no visible marks. They may be confused, disorientated or unable to remember parts of the incident clearly.

The absence of immediate reporting or visible injury should not automatically be treated as undermining credibility.

The court must look at the full context.

Non-Fatal Strangulation and PD12J

In private law children cases in England and Wales, allegations of domestic abuse should be considered under Practice Direction 12J.

PD12J requires the court to consider the nature of alleged domestic abuse, the impact on the child and parent, and whether a fact-finding hearing is necessary before decisions about child arrangements are made.

Where non-fatal strangulation is alleged, the court should not rush past it.

It may be directly relevant to:

• whether interim contact is safe;
• whether contact should be supervised or suspended pending findings;
• whether a fact-finding hearing is necessary;
• whether police disclosure is required;
• whether medical evidence is needed;
• whether Cafcass has properly assessed risk;
• whether the child has been exposed to domestic abuse;
• whether there is a risk of post-separation abuse;
• whether the parent alleging abuse needs special measures;
• whether there is a pattern of coercive and controlling behaviour.

The court’s welfare analysis under section 1 of the Children Act 1989 cannot be meaningful if serious risk indicators are minimised.

Non-fatal strangulation should be treated as a significant safeguarding issue, not a side allegation.

What Litigants in Person Should Record

If non-fatal strangulation has occurred, the evidence needs to be organised carefully. This is not because the survivor should have to prove everything perfectly. It is because the court process is evidence-led, and serious risk can be missed if it is presented in a fragmented way.

Where safe and possible, a litigant in person should try to gather and preserve:

• the date and approximate time of the incident;
• where it happened;
• how it happened — hands, arm, object, pressure to neck, pressure to mouth or nose, restriction of breathing;
• how long it lasted, if known;
• whether consciousness was lost or affected;
• whether there was dizziness, confusion, memory loss, incontinence, vomiting, headache, neck pain, voice change, swallowing difficulty or breathing difficulty;
• any photographs of visible injury, taken safely and with date records where possible;
• any GP, hospital, ambulance, SARC or medical records;
• any police report, crime reference number, body-worn video, 999 call or officer notes;
• any messages sent before or after the incident;
• any admissions, apologies, threats or minimising messages from the perpetrator;
• whether children saw, heard or were affected by the incident;
• whether the perpetrator made threats during or after the strangulation;
• whether there were previous similar incidents;
• whether the behaviour has increased in frequency or severity;
• whether separation, court proceedings or contact arrangements triggered escalation.

This information can then be used to create a chronology, position statement, C1A safeguarding form, witness statement, police disclosure request or schedule of allegations.

The purpose is not to overwhelm the court.

The purpose is to make the risk visible.

Do Not Let the Allegation Be Reframed as “High Conflict”

One of the recurring problems in family court is that serious domestic abuse can be reframed as parental conflict.

That is particularly dangerous where non-fatal strangulation is alleged.

“High conflict” suggests mutual hostility. It implies two people who cannot get along. It often leads to co-parenting language, communication apps, separated parenting courses and pressure to move forward.

But non-fatal strangulation is not a communication problem.

It is not poor conflict management.

It is not two parents needing to be more child-focused.

It is potentially lethal violence.

If it sits within coercive control, threats, stalking, harassment or sexual abuse, the correct analysis is safeguarding and risk — not parental conflict.

Litigants in person should be alert to language that minimises the allegation. Examples include:

• “There are allegations on both sides.”
• “Both parents need to move on.”
• “The parents need to communicate better.”
• “The mother is anxious.”
• “The father denies the allegation and wants contact.”
• “There is no visible evidence.”
• “The child was not directly involved.”
• “This is historic.”

Some of those observations may be relevant in a proper evidential analysis. But none of them should be used to bypass risk.

The court must ask what the allegation means for safety now.

Police Disclosure May Be Critical

Where non-fatal strangulation has been reported to the police, disclosure may be critical in the family court.

Relevant material may include:

• incident logs;
• 999 call recordings;
• body-worn video;
• officer notes;
• photographs;
• risk assessments;
• witness statements;
• custody records;
• interview summaries;
• charging decisions;
• bail conditions;
• restraining orders;
• victim personal statements;
• medical evidence obtained as part of the criminal investigation.

Family courts should be cautious about progressing child arrangements where key police evidence has not been obtained or considered.

That does not mean every case must wait indefinitely for the criminal process. But it does mean the court should not make unsafe decisions in an evidential vacuum.

Where a litigant in person asks for police disclosure, the request should be specific. It should explain why the material is relevant to child welfare, domestic abuse, PD12J, risk assessment and interim safety.

Cafcass Reports Must Be Scrutinised

Cafcass has an important role in private law children cases, but its reports should not be accepted uncritically where serious domestic abuse is alleged.

If non-fatal strangulation is part of the history, the court should ask:

• Did Cafcass identify non-fatal strangulation as a high-risk factor?
• Did Cafcass ask targeted questions about context, repetition and escalation?
• Did Cafcass consider coercive control?
• Did Cafcass consider the child’s exposure to domestic abuse?
• Did Cafcass rely too heavily on visible injury or criminal charge status?
• Did Cafcass distinguish between parental conflict and domestic abuse?
• Did Cafcass consider whether contact could be used for ongoing control?
• Did Cafcass recommend safe interim arrangements?
• Did Cafcass explain why any proposed contact is safe?

A report that minimises non-fatal strangulation should be challenged carefully and respectfully, with reference to evidence, risk, PD12J and the child’s welfare.

The issue is not whether a parent “likes” the recommendation.

The issue is whether the risk analysis is adequate.

Children Are Affected Even If They Did Not See It

Children do not have to witness strangulation directly to be harmed by it.

They may hear it. They may see the aftermath. They may notice fear, injury, silence, panic, police attendance or parental distress. They may become hypervigilant. They may be used as emotional leverage. They may be pressured to maintain contact with a parent who has made the household feel unsafe.

Under the Domestic Abuse Act 2021, a child can be recognised as a victim of domestic abuse if they see, hear or experience the effects of abuse and are related to the victim or perpetrator.

That matters in family court.

The question is not only whether the child was physically present in the room. The question is whether the child has experienced the effects of the abuse and what that means for welfare, safety and future arrangements.

Medical Evidence: Why It Should Not Be Overlooked

Medical evidence can be important, but it must be understood properly.

A lack of medical attendance does not mean the incident did not happen.

A lack of visible injury does not mean there was no danger.

But where medical evidence exists, it can help establish symptoms, injury, timing and impact.

The clinical guidelines on the management of non-fatal strangulation produced through the Institute for Addressing Strangulation provide detailed professional guidance for acute and emergency healthcare responses.

For litigants in person, the practical point is this: if medical help was sought, obtain the records where possible. If symptoms were reported to a GP, hospital, ambulance service, sexual assault referral centre or mental health professional, those records may be relevant.

If medical help was not sought, explain why. Fear, shock, coercive control, lack of visible injury, confusion and not understanding the medical risk may all be relevant context.

When Strangulation Is Raised in a Family Court Statement

A family court statement should not simply say: “He strangled me.”

That may be true, but it may not be enough to help the court understand the risk.

A clearer structure is usually:

• what happened;
• how breathing or consciousness was affected;
• what was said during the incident;
• what symptoms followed;
• what the perpetrator did afterwards;
• whether the children were exposed to it or affected by it;
• whether there had been earlier abuse;
• whether there has been escalation;
• what evidence supports the account;
• what protective orders or directions are requested.

For example, instead of presenting the allegation as an isolated event, a litigant in person may need to explain:

“This incident occurred after a period of escalating control, including threats, monitoring my movements, financial control and repeated intimidation. It was the first time he placed his hands around my neck. I believed I was going to die. Afterwards, his behaviour did not stop. He continued to threaten me and later used child contact arrangements to pressure me. I ask the court to treat this as part of a pattern of coercive control and escalating risk, not as a one-off argument.”

The wording must always be accurate to the evidence. But the principle is important: the court needs the trajectory, not just the incident.

What Orders or Directions Might Be Relevant?

Depending on the facts, a litigant in person may need to consider asking the family court for directions or orders such as:

• a fact-finding hearing under PD12J;
• police disclosure before any progression of contact;
• medical disclosure where relevant;
• Cafcass safeguarding analysis that specifically addresses non-fatal strangulation;
• special measures at hearings;
• separate waiting arrangements or screens;
• remote attendance where appropriate;
• supervised or supported contact only;
• suspension of direct contact pending findings where risk requires it;
• indirect contact only where necessary for safety;
• a prohibited steps order;
• a non-molestation order where appropriate;
• clear communication boundaries to prevent post-separation abuse.

These are not automatic. The court will consider the evidence, welfare, proportionality and the specific facts of the case. But where non-fatal strangulation is alleged, the court should not approach interim arrangements as if this is an ordinary parental dispute.

False Certainty Helps No One

It is important to be clear: allegations still need to be considered fairly.

The family court cannot simply assume every allegation is proved. Respondents are entitled to due process. Findings must be made on evidence. The court must avoid prejudging contested facts.

But fairness does not require naivety.

Fairness does not require the court to ignore risk.

Fairness does not require a survivor to keep facilitating unsafe arrangements while the system slowly gathers the evidence it should have prioritised from the start.

The proper approach is not to assume guilt. It is to manage risk intelligently while the facts are being determined.

That distinction matters.

Why This Matters for Litigants in Person

Litigants in person are often expected to navigate complex safeguarding issues without legal representation.

That is difficult in any case.

It is especially difficult where non-fatal strangulation is involved because the survivor may be traumatised, frightened, cognitively affected, financially controlled or still dealing with post-separation abuse.

They may also be facing a respondent who appears calm, articulate and child-focused in court.

That contrast can be devastating. The survivor may appear anxious or emotional. The perpetrator may appear reasonable. The court may then misread presentation as credibility.

This is why evidence structure matters.

A clear chronology, focused statement, targeted disclosure requests and careful PD12J submissions can help prevent serious risk from being lost in the noise of family court proceedings.

Practical Checklist for Litigants in Person

If non-fatal strangulation is part of your case, consider the following practical steps:

• Seek urgent medical advice if there are symptoms or concerns, even if there are no visible injuries.
• Report the incident to police if it is safe to do so.
• Keep a record of crime reference numbers, officer names and dates.
• Take photographs of any visible injuries, where safe.
• Save messages, emails, voicemails and social media evidence.
• Write down your memory of the incident as soon as you safely can.
• Record symptoms, including voice changes, swallowing difficulty, headaches, dizziness, confusion, memory loss or loss of consciousness.
• Record what the perpetrator said before, during and after the incident.
• Record whether children saw, heard or were affected by the incident.
• Build a chronology showing the wider pattern of coercive control and escalation.
• Ask the family court for police disclosure where relevant.
• Ensure the issue is clearly addressed in your C1A, statement or position statement.
• Challenge any report that minimises strangulation or treats it as ordinary conflict.
• Ask for special measures if attending court with the alleged perpetrator causes fear or distress.
• Seek specialist domestic abuse support where possible.

If you are in immediate danger, call 999. If you are not in immediate danger but need domestic abuse support, the National Domestic Abuse Helpline and Women’s Aid provide information and support.

Final Thought

Non-fatal strangulation is not a side issue.

It is not a minor assault.

It is not made safe by the absence of bruising.

It is not properly assessed by ticking “yes” on a risk form and moving on.

It is a critical warning sign.

Robert Kaiser’s work is important because it reminds professionals to stop thinking only in isolated incidents and start analysing escalation. That shift matters in policing, healthcare, safeguarding, advocacy and family court.

For litigants in person, the lesson is practical and urgent: where non-fatal strangulation is part of the history, the court must be helped to see the full pattern.

The frequency.

The intensity.

The loss of restraint.

The threats.

The fear.

The children’s exposure.

The post-separation behaviour.

The risk if it is minimised.

Because when strangulation occurs, the question is not merely whether a past incident happened.

The question is what it tells us about future danger.

And in family court, future danger is exactly what safeguarding is supposed to prevent.
