What Is a Child Arrangements Order

and do you need one?

Understanding when informal arrangements are enough, and when a court order is necessary.

Many separating parents manage co-parenting arrangements informally, without any court involvement. This works well when both parents can communicate and agree. But when arrangements break down or conflict makes agreement impossible, a Child Arrangements Order provides a legally binding framework.

What is a Child Arrangements Order?

A Child Arrangements Order (CAO) is a court order that sets out where a child lives, how much time they spend with each parent, and any other relevant arrangements. It replaced the old "residence" and "contact" orders in 2014.

Do you need one?

You do not need a CAO if both parents can agree and stick to arrangements. Many families co-parent perfectly well without one. A CAO becomes necessary when:

  • You cannot agree on arrangements
  • Arrangements are repeatedly not followed
  • One parent is preventing the other from seeing the children
  • There are concerns about a child's safety or welfare
  • One parent wishes to relocate with the children

How to apply

Before applying to court for a CAO, you must generally attend a MIAM (a Mediation Information and Assessment Meeting) unless an exemption applies. The court application is made using form C100.

Frequently asked questions

Can a Child Arrangements Order be changed?
Yes, either parent can apply to vary the order if circumstances change significantly. The court will consider what is in the best interests of the child.
What happens if someone breaches a Child Arrangements Order?
Breaching a CAO is a serious matter. The other parent can apply to enforce the order, which can result in fines, unpaid work requirements or in serious cases, imprisonment.
