Updated June 2026 · England & Wales
Changing a child's name is not something the law takes lightly. Because a minor cannot sign their own deed poll, the responsibility falls on those with parental responsibility, and everyone who holds that responsibility generally needs to be on board before the change can go ahead. Where agreement is not possible, a court order may be required instead. A Minor's Change of Name Deed is the formal instrument used to record the change, and it can be enrolled at the Royal Courts of Justice to create a permanent public record. This guide walks through how the process works, who needs to consent, what the document should contain, and the practical steps for getting schools, the passport office, the GP and others to recognise the new name. It is written for parents, guardians and anyone else navigating this on behalf of a child in England or Wales.

What this document is

A Minor's Change of Name Deed is a written declaration that formally records a change to the name of a child under 18. It is signed by the person or people with parental responsibility rather than by the child. The deed states the child's old name, their new name, and contains undertakings from the signing adults that the new name will be used going forward in all dealings and records relating to the child.

To be effective the document must be executed as a deed, which in practice means it is signed in the presence of an independent witness who also signs and provides their details. Once signed, the deed can either be kept privately as an unenrolled deed poll (which is how most parents use it) or submitted for enrolment at the Senior Courts of England and Wales, where it becomes part of the public record and is published in the London Gazette. Enrolment is optional but can add weight when dealing with certain institutions abroad.

How to use this document

  1. Confirm who holds parental responsibility. Before drafting anything, work out exactly who has parental responsibility for the child. This usually includes the mother, the father if married to the mother at the time of birth or named on the birth certificate (after 1 December 2003), and anyone holding a relevant court order. All of them generally need to agree in writing to the change.
  2. Get written consent from everyone with parental responsibility. If one parent refuses or cannot be contacted, you cannot simply proceed without them. You may need to apply to the family court for a specific issue order under the Children Act 1989. Pushing ahead without full consent can make the deed ineffective and cause real problems later with passports and schools.
  3. Prepare the deed with the correct wording. The document should clearly set out the child's full former name, the full new name, the date, and declarations that the signatories renounce the old name and will use the new name in all records and dealings. The child's age and the fact they are unmarried are typically stated, and the person signing confirms their authority to do so.
  4. Sign as a deed in front of an independent witness. Each person with parental responsibility signs the document, and each signature is witnessed by someone who is not a family member or beneficiary and is ideally a professional person such as a solicitor or accountant. The witness prints their name, adds their address and signs alongside. A deed that is not properly witnessed may not stand up to scrutiny.
  5. Notify the institutions that matter. Once the deed is executed, send certified copies or the original to HM Passport Office (to update the child's passport), the GP surgery, the school, HMRC for Child Benefit purposes, banks holding accounts in the child's name, and any other body that holds records. Keep the original safe, it is the evidence of the change.

Common questions

Q Do both parents have to agree to change a child's name?
If both parents hold parental responsibility, then yes, both generally need to give written consent. The same applies to anyone else who holds parental responsibility, for example through a child arrangements order. If agreement cannot be reached, the parent wanting the change can apply to the family court for a specific issue order, and a judge will decide based on what is in the child's best interests.
Q Does the child need to agree to the name change?
There is no fixed legal age at which a child's consent becomes formally required, but in practice a child aged 16 or 17 will usually need to sign their own deed poll as an adult. For younger children, particularly those over 12, the courts and bodies like HM Passport Office tend to expect their views to have been considered, and older children are often asked to give written agreement alongside their parents.
Q Do I have to enrol the deed at court?
No. Enrolment is optional. Most parents use an unenrolled deed poll, which is perfectly valid and accepted by the passport office, schools, the NHS and banks. Enrolment places the change on a public register kept at the Royal Courts of Justice and publishes it in the London Gazette. Some people choose this for added formality or when the child may live or travel extensively abroad.
Q Can I change my child's surname to a double-barrel?
Yes, a double-barrel or hyphenated surname is a valid choice, as is reverting to a previous family name. The same consent rules apply: every person with parental responsibility needs to agree. This is a common approach after separation or remarriage because it recognises both parents while still giving the child a connection to a new family unit.
Q Will the child's birth certificate be updated?
No. A deed poll changes the name a person uses, it does not alter the birth certificate. The birth certificate remains a permanent record of the name registered at birth. Only in limited circumstances, such as re-registration following a parent being added or adoption, can the birth record itself be changed. The deed poll sits alongside the birth certificate as evidence of the current legal name.
Q How long does the process take?
Executing the deed itself can be done in a single day once everyone with parental responsibility is ready to sign and a witness is available. Updating passports, schools and other records takes longer and depends on each organisation. HM Passport Office will issue a new passport in the child's new name on receipt of the deed and the usual application documents. Court enrolment, if chosen, adds several weeks.
Q What if the other parent cannot be found?
If the other parent holds parental responsibility but genuinely cannot be located, you should not simply proceed without them. You may need to apply to the family court for permission to change the name without their consent, showing evidence of the steps taken to find them. This is a situation where getting guidance before you act can save considerable time and cost later.
