The Welfare Checklist: How Welsh Courts Decide Child Custody

When parents in Wales can't agree on child arrangements and the case reaches court, the judge doesn't decide based on who makes the better argument or who has the more expensive solicitor. Every decision is measured against a specific, statutory framework: the welfare checklist under Section 1(3) of the Children Act 1989.

Understanding these seven factors is essential for any parent preparing for family court — they're the lens through which every proposal you make will be evaluated.

The Paramountcy Principle

Before the checklist itself, the overarching rule: Section 1(1) of the Children Act 1989 states that the child's welfare is the court's "first and paramount consideration." This means the child's interests override everything else — parental preferences, fairness between adults, financial convenience, and logistical ease all come second.

The judge also applies the "no order" principle under Section 1(5): the court won't issue a formal order unless doing so would be demonstrably better for the child than leaving parents to sort things out themselves. If you're asking the court to impose a specific arrangement, you need to show why a court order serves the child's interests better than an informal agreement.

The Seven Factors

1. The Child's Wishes and Feelings

The court considers what the child wants, assessed in light of their age and maturity. In Wales, Cafcass Cymru officers meet with children directly during the Pathfinder investigation — often within the first few weeks after a C100 is filed — to gather their views.

Children don't get a veto. A 7-year-old who says they want to live with the parent who lets them stay up late isn't going to drive the decision. But an articulate 13-year-old with clear, consistent preferences carries significant weight, particularly if those preferences aren't simply echoing one parent's position.

Courts are alert to signs that a child's expressed wishes have been influenced by a parent. Cafcass Cymru officers are trained to distinguish between a child's genuine feelings and coached responses.

2. Physical, Emotional, and Educational Needs

This factor covers the full range of what the child needs to thrive: stable housing, consistent routines, access to their school, emotional security through attachment bonds, and support for any special educational or developmental needs.

Judges look at which parent can practically meet these needs. Who lives closer to the school? Who manages the child's medical appointments? Who supports their extracurricular activities? These practical realities often matter more than abstract arguments about parenting philosophy.

3. The Likely Effect of Any Change

Courts operate with a status quo bias. If a child is settled — attending a particular school, living in a familiar home, embedded in a friendship group — the court is reluctant to disrupt that arrangement unless there's a compelling reason.

This cuts both ways. If the child has been primarily with one parent since separation and is thriving, the court will need strong evidence to justify moving them. But if the current arrangement was put in place hurriedly or isn't working, the court will consider change.

4. Age, Sex, Background, and Relevant Characteristics

This is a broad category that allows the court to consider the child's cultural heritage, language needs, religious upbringing, and any disability or health condition. In Wales, this factor has particular significance for Welsh-speaking families — a child who attends a Welsh-medium school and is embedded in Welsh-language cultural life has needs that must be reflected in the arrangement.

5. Any Harm Suffered or at Risk of Suffering

"Harm" is defined as ill-treatment or impairment of health or development. This covers domestic abuse (including witnessing it), child abuse, neglect, substance misuse, and severe parental conflict.

In the Welsh Pathfinder model, harm allegations are investigated from the outset through multi-agency checks. If you've filed a C1A form alleging harm, Cafcass Cymru will investigate these allegations as part of the Child Impact Report rather than leaving them to surface later in proceedings.

6. Parental Capability

The court assesses each parent's ability to meet the child's needs — practically, emotionally, and financially. This includes each parent's physical and mental health, parenting skills, work commitments, and housing arrangements.

One factor that courts weigh heavily is the "friendly parent" principle: which parent is more willing to facilitate a healthy relationship with the other parent? A parent who actively supports the child's contact with the other parent scores well on capability. A parent who obstructs contact or makes derogatory comments about the other parent in front of the child does not.

7. The Range of Powers Available to the Court

The court can make a "lives with" order, a "spends time with" order, a prohibited steps order, a specific issue order, or no order at all. The judge considers which combination of powers best serves the child — including whether a formal order is even necessary.

How to Present Your Case Against the Checklist

When preparing for your Cafcass Cymru call or court hearing, frame everything around the welfare checklist rather than around what you want as a parent. Instead of "I deserve more time with my children," show how your proposed arrangement meets each factor: the child's school is near your home (need), they've expressed wanting to spend more time with you (wishes), the change won't disrupt their routine (effect of change), and you'll support their relationship with the other parent (capability).

The Wales Child Custody & Parenting Plan Guide includes a welfare checklist worksheet that helps you map your proposed arrangements against each of the seven factors — so you can present a child-focused case from your first Cafcass Cymru interaction through to the final hearing.
