# Changing Your Child’s Surname: Rules and Consent

Quick answer

To change a child’s surname in the UK you need a child deed poll applied for by a parent or guardian, plus the written consent of everyone who holds parental responsibility. Without everyone’s consent the only route is a Specific Issue Order (form C100). Our £17.99 pack includes the consent letters.

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](/child-deed-poll/) 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](/parental-responsibility-name-change/) and [whether the father has to agree](/fathers-consent-name-change/) 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](/adult-deed-poll/) or the [free template](/free-deed-poll-template/). Who can change a name at all: [who can change their name](/who-can-change-their-name/).

## Frequently asked questions

### Who can apply to change a child’s surname?+

A parent or guardian who holds parental responsibility applies on the child’s behalf — but the change needs the written consent of everyone who holds parental responsibility, not just the applicant.

### What if the other parent refuses?+

There is no lawful shortcut: your only route is applying to the family court for a Specific Issue Order using form C100, and a judge decides based on the child’s welfare. We will not sell a document that would not be valid.

### Does it matter whether the father is on the birth certificate?+

Yes. An unmarried father not named on the birth certificate, without a court order or parental responsibility agreement, does not hold parental responsibility — so his consent is not legally required. If you are unsure who holds parental responsibility, check gov.uk before ordering.

### What documents will schools and HMPO want?+

The signed child deed poll plus the signed consent letters from every holder of parental responsibility. Schools and GPs usually accept a photocopy; HMPO wants the original wet-ink deed poll.
