Changing a Child's Name: The Legal Requirements

January 2026 9 min read Parental Consent Required

Changing a child’s name is a serious legal step in the UK. Unlike an adult name change, you cannot simply sign a document yourself. You must navigate the rules of Parental Responsibility (PR) to ensure the change is permanent and legally recognized.

The Golden Rule

To change a child's name by Deed Poll, you must obtain the written consent of every person who holds Parental Responsibility for that child. Without this, the Deed Poll will be rejected by the Passport Office and schools.

1. Who Has Parental Responsibility?

Before ordering a Child Deed Poll, you must identify who needs to sign the consent form. PR is generally held by:

The Mother

Always has Parental Responsibility from birth.

The Father

Has PR if married to the mother at birth, or if listed on the Birth Certificate (for births after 2003 in England/Wales).

2. When Consent is Missing

If the other parent refuses to give consent, or if their whereabouts are unknown, you cannot use a standard Deed Poll service. You will likely need to apply for a Specific Issue Order from the Family Court.


Important Warning

Attempting to change a child's name without the consent of another PR holder is a breach of the Children Act 1989. Always ensure you have the correct "Letter of Consent" ready to accompany the Deed Poll.

3. The Process for 16 & 17 Year Olds

Once a young person reaches the age of 16, the rules change significantly. They are considered old enough to choose their own name.

Child Name Change FAQs

Does it change the birth certificate?

No. A Deed Poll changes the child's name for all current and future records (Passport, GP, School), but the birth certificate remains as a historical record.

Can I add a father to the deed?

A Deed Poll is only for changing names. If you wish to add a father to a birth certificate to grant him PR, you must contact the General Register Office.
