The Family Court's duty to promote a child's welfare — the 'welfare principle'

REVIEWED BY: Sean McNamara on 2026-08-31

The welfare principle — the foundation of all children law

Section 1(1) Children Act 1989 states that when a court decides any question about a child's upbringing, the child's welfare is the court's paramount consideration.

"Paramount" means: when the court weighs everything (the parents' wishes, practicalities, other factors), what is best for the child is the deciding factor — not what is 'fairest' between the adults.

What it means in practice

Courts do not ask 'who is the better parent?'
They ask: given the child's needs and circumstances, what arrangement best serves them?
A parent's frustration, hurt, or view of the other parent is secondary
The court presumes both parents' involvement benefits the child unless there's good reason (e.g. risk of harm)

The welfare checklist (s.1(3))

To apply the principle, the court considers the seven factors:

1. Child's wishes and feelings 2. Physical, emotional, educational needs 3. Effect of change 4. Age, sex, background, characteristics 5. Harm suffered or at risk 6. Capability of each parent to meet needs 7. The court's powers

See our welfare-checklist deep-dive for a worked example.

How to use this in your case

Frame every argument around the child, not the adult dispute:

Instead of: "My ex is difficult and refuses to cooperate"
Say: "The child's educational needs (factor 2) and stability (factor 3) are best served by the current school and a consistent routine, which I can provide."

Evidenced, child-focused facts win. Personality grievances don't.

When welfare can be outweighed

The welfare principle governs children questions. For financial remedy, the test is different (needs, fairness, contributions — see our financial remedy guide). For grandparents or relatives seeking a role, the same welfare principle still drives contact decisions.
