Changing Your Child’s Surname: Rules and Consent
Quick answer
Who should skip this
Skip this pack if anyone with parental responsibility will not consent — a deed poll without that consent is not valid. From age 16 the young person executes an adult deed poll instead. Do not buy this to bypass a court dispute.

What is the process for changing a child’s surname?
A parent or guardian completes a child deed poll on the child’s behalf. Every holder of parental responsibility signs a consent letter. The deed poll is signed in ink in front of two independent witnesses aged 18 or over. Keep the consent letters with the deed poll — HM Passport Office and schools may ask for them.
The £17.99 child deed poll pack generates both documents together. Enrolment is not available under 18, so this is always an unenrolled deed. A child’s passport name change is a child renewal (£66.50 online, GOV.UK fees checked 13 August 2026) plus the original deed and the consent letters.
Why does consent matter so much for surnames?
A surname signals family identity, and the law treats changing it as a major decision, so every holder of parental responsibility must agree — whatever the contact or maintenance arrangements. Consent disputes after separation are the single most common reason child deed polls fail at schools and at HM Passport Office.
Read parental responsibility and name changes and whether the father has to agree before you pay. If you are unsure who holds parental responsibility, check GOV.UK rather than guessing — an unmarried father not on the birth certificate often does not hold it.
What happens without the other parent’s consent?
Any deed poll made without everyone’s consent is not valid, and record-holders who discover the dispute will refuse it. The lawful route is a Specific Issue Order on form C100. A court fee applies, and a judge decides on the child’s welfare. Free official guidance is on GOV.UK.
We ask about consent before payment and block the purchase if it cannot be confirmed. That is a skip-us rule, not a sales objection. Do not use an adult deed poll in the child’s name as a workaround — organisations check age and parental responsibility.
Can a teenager change their own surname?
From 16, yes: a person executes their own adult deed poll and no parental consent is required. Child deed polls are for under-16s only. The adult document is £14.99 from us, or free if they copy the government wording themselves and can find two independent witnesses.
Adult route: adult deed poll or the free template. Who can change a name at all: who can change their name.
