Legal guides • England & Wales

The allegations that decide family cases, explained.

Most contested child-arrangements cases turn on allegations: coercive control, domestic abuse, harassment, alienating behaviours. These guides explain what the law actually says, what the court looks for, and why the message record — timestamps, patterns, context — so often decides the outcome.

This is general information, not legal advice. These guides describe the law of England & Wales in plain English, with links to the original statutes, judgments and official guidance so you can check everything yourself. Every case is different: for advice on your situation, speak to a solicitor (find one via the Law Society) or a service such as Citizens Advice. If you or a child are in immediate danger, call 999.
The framework

How the family court decides child arrangements.

The child's welfare comes first

Under section 1 of the Children Act 1989, the child's welfare is the court's paramount consideration. The court works through the statutory "welfare checklist" — the child's wishes and feelings, their needs, the likely effect of change, any harm suffered or at risk of being suffered, and how capable each parent is of meeting the child's needs.

Since the Children and Families Act 2014, "residence" and "contact" orders were replaced by a single child arrangements order under section 8, settling who a child lives with and spends time with. The court also starts from a presumption that involvement of both parents furthers the child's welfare — unless the contrary is shown, for example by evidence of a risk of harm.

Cafcass and safeguarding

Cafcass (the Children and Family Court Advisory and Support Service) carries out safeguarding checks in every case and, where ordered, deeper welfare reports. Its advisers assess allegations using the Child Impact Assessment Framework.

Where abuse is alleged: PD12J

Practice Direction 12J of the Family Procedure Rules applies whenever domestic abuse is alleged or admitted. The court must consider the allegations at every stage, decide whether they are relevant to the orders sought, and must not make an order that exposes a child or parent to an unmanageable risk of harm.

Fact-finding hearings

Where disputed allegations matter to the outcome, the court can hold a fact-finding hearing: a mini-trial where each allegation is proved or not proved on the balance of probabilities. The Court of Appeal in Re H-N [2021] EWCA Civ 448 told courts to focus on patterns of behaviour, not just isolated incidents, and in K v K [2022] EWCA Civ 468 confirmed a fact-finding hearing should only be held where it is necessary and proportionate to deciding the child's welfare.

Legal aid

Legal aid for family cases is limited, but there is a domestic-abuse evidence gateway: with prescribed evidence of abuse (from a GP, police, refuge, court order and more), means-tested legal aid can be available.

Flagship guides

Four allegations. Four deep guides.

Each guide covers the statute, the leading cases, what the court looks at, and — because it is where we live — what message evidence actually proves the pattern.

Serious Crime Act 2015 s76 • PD12J

Coercive & controlling behaviour

The criminal offence, the Domestic Abuse Act definition, and why F v M and Re H-N made the pattern — not the single incident — the unit of proof. Message frequency, monitoring language and escalation over time are exactly what courts now expect to see evidenced.

Domestic Abuse Act 2021 • Children Act 1989

Domestic abuse in child arrangements

The 2021 statutory definition, children as victims in their own right, PD12J duties, fact-finding hearings and the welfare checklist — and how a dated, complete message record survives scrutiny where cherry-picked screenshots don't.

Protection from Harassment Act 1997 • FLA 1996

Harassment & stalking

Course of conduct, the stalking offences, Stalking Protection Orders, and non-molestation orders. The law turns on two or more occasions and on what happened after you asked them to stop — which is a counting-and-timeline problem.

FJC guidance 2024 • Cafcass CIAF

Parental alienation / alienating behaviours

No statute defines it, courts treat it as a question of fact, and the Family Justice Council's December 2024 guidance reset the whole area. What "alienating behaviours" means, what must be proved, and what the message record can and cannot show.

Other allegations

The wider allegation landscape.

Child-arrangements disputes raise many other allegation types. Short orientation notes below — each engages the same welfare checklist and, where relevant, PD12J and fact-finding machinery described above.

Neglect

Persistent failure to meet a child's basic physical or emotional needs — food, warmth, supervision, medical care, schooling. In private law it feeds the "harm" and "capability" limbs of the welfare checklist; in public law it is a classic route to the significant-harm threshold in Children Act 1989 s31. Contemporaneous messages about missed meals, appointments and handovers often matter more than either parent's later recollection.

Physical abuse of a child

Allegations of hitting, shaking or other physical harm are among the most serious the family court hears, and are frequently mirrored by police involvement. The court will usually need findings of fact before deciding arrangements, guided by PD12J and the significant-harm threshold.

Sensitive category: do not run this through a self-serve tool. Speak to a solicitor, and if you want analysis support, use our solicitor-supervised White-Glove / Court Bundle tier so everything is handled under legal privilege and proper safeguarding.

Emotional abuse

Sustained belittling, intimidation, blaming or frightening of a child — or making a child witness abuse of a parent (expressly part of "harm" under the Children Act, and the child is a victim in their own right under Domestic Abuse Act 2021 s3). Patterns across months of messages are usually the best available evidence.

Sexual abuse / failure to protect

Allegations of sexual abuse, or that a parent failed to protect a child from a known risk, trigger the most careful fact-finding the family court does, alongside any criminal process. Specialist legal representation is essential.

Sensitive category: do not run this through a self-serve tool. Contact a solicitor immediately; the NSPCC helpline (0808 800 5000) can also advise. Analysis support, if any, belongs in our solicitor-supervised White-Glove tier only.

Exposure to harm / unsafe environment

Allegations that a home or lifestyle exposes the child to danger — unsafe adults present, drug use around the child, dangerous driving with the child, chaotic conditions. Courts look for specific, dated examples rather than general assertions; messages arranging or admitting the incidents are frequently decisive.

Substance misuse

Alcohol or drug misuse is relevant to the "capability" limb of the welfare checklist. Courts can order hair-strand or liver-function testing; message evidence (timing of incoherent messages, admissions, missed handovers after benders) is often what justifies ordering the tests.

Mental health & capacity

A parent's mental ill-health is only relevant insofar as it affects parenting capacity or exposes the child to harm — the diagnosis itself decides nothing. Courts may direct psychiatric or psychological expert evidence under FPR Part 25. Sustained message records can evidence both concerning episodes and, equally, long stable periods.

Criminal convictions & dangerous associations

Relevant convictions (violence, sexual offences, drugs) and associations with dangerous individuals go to risk of harm. The court can obtain police disclosure; Cafcass safeguarding letters flag known history at the first hearing.

Abduction risk

Fear that a parent will remove a child from the jurisdiction. Courts can make prohibited-steps orders, port-alert requests and passport orders at speed. Messages threatening removal ("you'll never see her again, we'll be gone") are treated seriously and are exactly the kind of line that needs its full context preserved.

Breach of court orders

Repeatedly ignoring a child arrangements order can lead to enforcement orders, unpaid work requirements, costs — and ultimately a change of living arrangements. Enforcement turns on a clean, dated log of each breach against the order's terms: a timeline problem before it is a legal one.

False or exaggerated allegations

Courts do find, in some cases, that allegations were fabricated or inflated — and such findings damage the maker's credibility and can themselves amount to abusive conduct. The protection against being falsely accused is the same as the proof of a true allegation: the complete, timestamped record, not selected fragments.
