The honest answer on full custody
No one publishes a figure for how often mothers get "full custody" in the UK. That phrase is not one order. It can mean the child lives mainly with you, or that the other parent's time is limited. Big decisions stay shared with anyone else who has parental responsibility, unless a court settles an exact issue.
The courts keep no mother-versus-father table of outcomes, and most parents agree arrangements without a judge. Your outcome depends on the child's welfare, the evidence, and the exact order you ask for.
What "full custody" means in England and Wales
England and Wales does not use "custody." There is parental responsibility — your legal rights and duties as a parent, and a child arrangements order. This says who the child lives with and when they see the other parent.
You can be the parent a child lives with while the father keeps parental responsibility and regular time. So decide what you actually need: the child living mainly with you, safer handovers, a set school-week pattern, or a say over school or health. Scotland and Northern Ireland have their own laws and still use residence and contact orders. Our plain-English guide to parental responsibility and court orders explains the rules, and also covers Scotland and Northern Ireland.
What the court weighs
Under section 1 of the Children Act 1989, the child's welfare is the court's paramount consideration. When an application is opposed, the judge must work through the welfare checklist in section 1(3). It covers the child's wishes and feelings, their needs, the effect of change, any risk of harm and how well each parent can meet them.
Where a parent can be involved without putting the child at risk of harm, the court presumes that involvement will further the child's welfare. Involvement does not need equal time, and gender alone does not decide the order. The government plans to repeal this presumption through the Courts and Tribunals Bill. But it applies until that Bill becomes law.
When you may seek sole or limited arrangements
A court may limit the other parent's role where the evidence shows it protects the child. For example proven abuse, abandonment, or care that is not safe. These are not automatic, and you should test them with a solicitor.
Conflict on its own is not enough. Record the things that matter: missed medical information, broken agreements, unsafe handovers, or threats, and keep an allegation separate from a proven finding.
The numbers you will see online
For scale, the government estimated about 2.4 million separated families in Great Britain, with 3.9 million children, in the year to March 2025. In April to June 2026, a private law case took 33 weeks on average to be disposed of. In about half of cases (51%), neither parent had a lawyer.
A 2025 pilot review of nearly 300 case files at three family court sites found domestic abuse raised in 87% of them. These figures give context and show why safeguarding is taken seriously. They are not a success rate.
Keep a record that helps
Your case is easier to prepare when a solicitor can see, at a glance, what was planned, what happened, the effect on the child, and the proof. Keep the current order, message threads, changes, and any school or medical records you are allowed to hold.
Note everyday working together too — it shows the limits of a pattern. Casewell keeps your dated notes, files and parenting-time records in one place, ready to export as a focused PDF.

If safety is a concern
Record what you saw, heard or received, with the date, the source, and what happened next. Keep official reports and complete messages where it is lawful to do so.
Do not question your child over and over for evidence. An allegation is not a finding, and an investigation is not proof. If anyone is in immediate danger, contact emergency services or a specialist domestic-abuse service.
Your next steps
Save any current order, track parenting time for a few weeks, and write out the arrangement you want in plain terms. Not just the phrase "full custody."
Then take it to a family-law solicitor, who can match it to the right kind of order and tell you what to disclose. A private record supports that advice. It does not replace it.

Use this before a solicitor or mediator asks for a basic timeline of events.
Build the record behind your application
Casewell keeps your private timeline, handovers, messages, expenses and supporting files together. Record events while they are fresh, keep the full context, and export a focused PDF for solicitor review. That can save time and cost and help an expert show a pattern of abuse, unsafe care or non-working together clearly. It cannot guarantee full custody, but it gives your application a reliable factual base.
Does the UK publish the percentage of mothers who get full custody?
No reliable national percentage is published. “Full custody” also combines different outcomes, including where a child lives, how a disputed decision is settled and restrictions on time.
Does a mother automatically get full custody?
No. The court applies the child’s welfare test. A mother’s care history may be relevant. But gender alone does not decide the order.
What helps a mother seek a sole or primary arrangement?
A child-focused proposal supported by dated, lawful evidence about care, safety, practical impact and the other parent’s conduct gives a solicitor something exact to assess.
