Parental Responsibility and Changing a Child’s Name

Quick answer

Everyone who holds parental responsibility for a child must consent before the child’s name can be changed — usually both parents named on the birth certificate, plus anyone with parental responsibility through a court order or adoption. A child deed poll made without every required consent is not valid; the fallback is a Specific Issue Order (form C100) from the family court.

What is parental responsibility?

Parental responsibility is the legal bundle of rights and duties a parent has for a child — and changing a child’s name is one of the decisions that requires the agreement of everyone who holds it. Mothers always hold it; fathers hold it if married to the mother at the birth or named on the certificate (post-2003 registrations in England and Wales); others acquire it by court order, agreement or adoption.

How does consent work in practice?

Each holder of parental responsibility signs and dates a consent letter stating they agree to the change from the child’s current name to the new name. Keep the signed letters with the deed poll — HMPO and schools may ask for them. Our child deed poll pack generates a consent letter for each person automatically.

What if someone refuses or cannot be found?

Then a deed poll cannot lawfully proceed. Your route is a Specific Issue Order using form C100 — the court fee applies and a judge decides based on the child’s welfare. Free guidance is at gov.uk/change-a-childs-name. See also does the father have to agree?.

Does a 16-year-old still need parental consent?

No — from 16 a person executes their own adult deed poll and no one’s consent is required. The consent rules on this page apply to under-16s only.
