Appointing a Guardian for Children in Your Will UK

Last updated: March 2026 · 4 min read

If you have children under 18, naming a guardian in your Will is one of the most important decisions you can make. Without a named guardian, a court decides who raises your children if both parents die. Do not leave this to chance.

Why Naming a Guardian Matters

If both parents die while children are under 18, someone must take over parental responsibility. Without a named guardian in a Will, the court decides — it may not be the person you would have chosen, and the process can be distressing and slow for the children.

💡 A guardian and a trustee are different roles. The guardian raises the children. The trustee manages any inherited money. You can appoint the same person for both — or different people.

How to Choose a Guardian

Consider:

Appointing a Guardian in Your Will

Name your guardian in your Will with their full name and address. You can appoint joint guardians (useful for couples) or a substitute guardian in case your first choice cannot act. The appointment takes effect only when all people with parental responsibility have died.

Can a Guardian Be Changed?

Yes — you can update your Will at any time to change the named guardian. Review your choice if circumstances change: the guardian moves abroad, has a significant lifestyle change, or your relationship changes.

A Note on Trustees for Children

Children under 18 cannot inherit directly. Any legacy left to a minor child is held by trustees until they reach the age you specify in the Will (18 minimum; you can extend to 21 or 25). Choose trustees carefully — ideally people with financial common sense.
