How to Legally Change Your Child’s Name in the UK: A Parent’s Guide

A Parent’s Guide to Changing a Child’s Name

Changing a child’s name is a significant legal step and requires the consent of everyone with parental responsibility. Whether the change is due to family circumstances, a new marriage, or a desire to create a unified family identity, there is a clear legal process that must be followed to ensure the change is recognised by schools, healthcare providers, and official bodies.

When Can a Child’s Name Be Changed?

A child’s surname can only be changed if:

• Everyone with parental responsibility agrees, or
• The Family Court grants permission.

Changing a first name may follow a similar process, but surname changes carry greater legal weight, particularly when a dispute arises.

Who Has Parental Responsibility?

Parental responsibility means having legal rights and duties in relation to a child. You may have parental responsibility if:

• You are the biological mother
• You are the father named on the birth certificate
• You are a step-parent who has legally acquired parental responsibility
• You have adopted the child or have a court order granting it

If more than one person holds parental responsibility, you cannot change the child’s surname without their agreement.

How Can I Change My Child’s Name?

1. With Everyone’s Consent

If all individuals with parental responsibility agree, the child’s name can be changed using a deed poll.

• A deed poll is a legal document that proves a change of name.
• You will need to complete a Child Deed Poll application—this can be arranged through a solicitor or via an official deed poll service.
• Written, signed consent is typically required from all parties with parental responsibility.

Once the deed poll has been executed, you should inform relevant organisations such as:

• The child’s school
• Their GP
• The passport office

2. Without Consent – Court Application

If someone with parental responsibility does not agree to the name change, you must apply to the Family Court for a Specific Issue Order under Section 8 of the Children Act 1989.

• This application is made using form C100.
• The court will assess the reason for the proposed change and whether it is in the child’s best interests.
• The child’s welfare is the court’s paramount consideration.
