When a relationship ends and children are involved, the most pressing question is rarely about money — it is about the children themselves. Who will they live with? How often will they see each parent? And who decides? In England and Wales, the answers turn on a single, deceptively simple principle: the welfare of the child comes first, above everything else.
It surprises many parents to learn that the language they expect — "custody," "access," "residence" — has largely vanished from the law. The framework today is gentler in its terminology and sharper in its focus. It is built not around the rights of parents, but around the needs of children. Understanding that shift is the first step to navigating it well.
"Custody" is the wrong word — and what a Child Arrangements Order really is
The word "custody" has not been part of English family law for more than three decades. The Children Act 1989 swept it away, along with "access," precisely because those terms framed children as possessions to be won or lost. What matters now is not who "has" the child, but the practical arrangements for the child's life.
Where parents cannot agree, the court can make a Child Arrangements Order. This single order can settle two distinct questions: with whom a child is to live, and with whom — and when — a child is to spend time or otherwise have contact. An order may provide that a child lives with one parent and spends time with the other, or that the child's time is genuinely shared between two homes. The label carries no automatic legal weight; the substance of the arrangement is what counts.
Crucially, both parents usually retain parental responsibility — the bundle of rights and duties that includes a say in schooling, medical treatment, and religion — regardless of where the child lives. A living arrangement does not strip the other parent of their voice in the big decisions of a child's life.
The paramount welfare principle and the welfare checklist
At the heart of every decision sits section 1 of the Children Act 1989. It states that when a court determines any question about a child's upbringing, the child's welfare is the court's paramount consideration. Not a primary consideration to be balanced against others — the paramount one. The wishes of the parents, however heartfelt, yield to it.
The child's welfare is not merely the most important factor. It is, in the words of the statute, paramount — the lens through which every other consideration is viewed.
To give that principle structure, the Act sets out a "welfare checklist": a list of factors the court must weigh when a contested order is in question. The checklist is not a scoring system, and no single factor is decisive. It is a disciplined way of ensuring nothing important about the particular child before the court is overlooked.
Under section 1(3) of the Children Act 1989, the court must have regard, in particular, to:
- The child's ascertainable wishes and feelings, considered in light of their age and understanding.
- The child's physical, emotional and educational needs.
- The likely effect on the child of any change in their circumstances.
- The child's age, sex, background and any characteristics the court considers relevant.
- Any harm the child has suffered or is at risk of suffering.
- How capable each parent (and any other relevant person) is of meeting the child's needs.
- The range of powers available to the court under the Act in the proceedings in question.
A child's wishes carry real weight, increasingly so as the child grows older — but they are never the sole answer. A teenager's settled view will be taken seriously; a younger child's preference is one strand among many. The court's task is to filter every factor through the single question of what genuinely serves this child's welfare.
The strong presumption in favour of resolving matters out of court
For most families, court is the wrong place to settle arrangements for children — and the law is deliberately built to keep them out of it. Litigation is slow, expensive, and adversarial; it can entrench conflict at precisely the moment children most need their parents to cooperate. The system therefore treats the courtroom as a last resort, not a first step.
Many separating parents are able to agree a parenting plan: a written, practical record of where the children will live, how time will be shared across the week, holidays, schooling, and how decisions will be made. Such a plan has no special legal status, but it works precisely because both parents have built it together.
Where direct agreement is difficult, family mediation offers a structured, confidential setting in which a neutral mediator helps parents find workable arrangements. To reinforce this, anyone wishing to apply to court for a child arrangements order must ordinarily first attend a Mediation Information and Assessment Meeting (MIAM) to consider whether mediation could resolve matters. There are limited exemptions — notably where there has been domestic abuse or genuine urgency — but for most families the MIAM is a required gateway, and a genuine opportunity to avoid court altogether.
What happens if you go to court
When agreement genuinely cannot be reached, an application is made on the appropriate form and the matter enters the family court. From the outset, the proceedings are shaped to keep the child's welfare central and to test, at every stage, whether court involvement is truly necessary.
An early and important step is the involvement of Cafcass — the Children and Family Court Advisory and Support Service. A Cafcass officer carries out initial safeguarding checks and may, where the court directs, prepare a welfare report assessing the child's circumstances and, where appropriate, the child's wishes and feelings. Cafcass acts independently of both parents; its role is to advise the court in the interests of the child.
Where serious allegations are made — for example, of domestic abuse — the court may hold a fact-finding hearing to determine, on the balance of probabilities, what actually happened, before deciding what arrangements are safe. Findings of fact then inform the welfare assessment that follows.
Throughout, the court is guided by the "no-order" principle, also found in section 1 of the Act: the court must not make any order unless doing so would be better for the child than making no order at all. If parents reach agreement during proceedings, or if a formal order would add nothing, the court may simply decline to impose one. The aim is always the least intervention consistent with the child's welfare.
- English law no longer speaks of "custody" or "access" — the court makes a Child Arrangements Order settling where a child lives and when they spend time with each parent.
- The child's welfare is the court's paramount consideration, applied through the statutory welfare checklist under the Children Act 1989.
- The law strongly favours resolving matters out of court through parenting plans and mediation; a MIAM is usually required before any court application.
- If you do go to court, Cafcass advises on the child's welfare, fact-finding hearings resolve serious allegations, and the no-order principle keeps intervention to a minimum.
- Both parents normally keep parental responsibility — and a real say in major decisions — whatever the living arrangement.
