Change a Child's Name in the UK [2026 Parental Consent & Deed Poll Guide]
Changing a child's name in the UK requires careful consideration and, crucially, the consent of all parents with parental responsibility. This comprehensive guide explains the legal requirements, process, and everything you need to know about changing your child's name legally and safely.
Key Requirements
- Under 16: ALL parents with parental responsibility must consent
- 16-17 years: The young person can change their own name
- Document needed: Deed poll signed by all parents/guardians
Who Has Parental Responsibility?
This is CRUCIAL - Read Carefully
You MUST have consent from ALL people with parental responsibility. Changing a child's name without proper consent is illegal and the name change will be invalid.
Who Automatically Has Parental Responsibility:
- Mothers: Always have parental responsibility automatically
- Fathers married to mother: When child was born or at any time after
- Fathers (unmarried): If registered on birth certificate (after Dec 2003)
- Adoptive parents: Both adoptive parents
- Legal guardians: Appointed by court or will
Who Does NOT Have Parental Responsibility:
- ✗Step-parents (unless adopted child or granted by court)
- ✗Grandparents (unless appointed legal guardians)
- ✗Unmarried fathers NOT on birth certificate (before Dec 2003)
- ✗New partners/spouses (unless they've adopted the child)
The Process for Different Age Groups
Children Under 16
Requirements:
- • Consent from ALL parents with parental responsibility
- • Each parent must sign the deed poll
- • Deed poll must include parent/guardian details
- • Child does not sign (parents sign on their behalf)
Important: If one parent refuses consent, you may need to apply to court for permission. Simply proceeding without their consent is illegal.
Young People 16-17 Years Old
Good news - more independence!
- • Can change their own name without parental consent
- • Signs the deed poll themselves (like an adult)
- • Still needs 2 witnesses (not parents)
- • No court permission required
Note: While parental consent isn't legally required, it's often wise to discuss the decision with parents.
Step-by-Step Process
Confirm All Parents Consent
Contact all parents/guardians with parental responsibility and ensure they agree to the name change. If one parent disagrees, you cannot proceed without court permission.
Tip: Get written confirmation from each parent before ordering the deed poll
Order a Child Deed Poll
When ordering, you'll need to provide:
- • Child's current full name
- • Child's new chosen name
- • Child's date of birth
- • Details of ALL parents with parental responsibility
- • Each parent's full name and address
All Parents Sign the Deed Poll
Once you receive the deed poll certificate:
- • ALL parents must sign in the presence of 2 independent witnesses
- • Witnesses must be over 18, not related, not living at same address
- • Witnesses watch parents sign, then sign themselves
- • The child does NOT sign (if under 16)
Update Child's Documents
Use the signed deed poll to update:
- • Child's passport (if they have one)
- • School records
- • NHS records
- • Bank accounts (if applicable)
- • Child Benefit records
- • Any other official documents
Common Scenarios
Changing child's surname after remarriage
If you've remarried and want your child to take your new spouse's surname, you STILL need consent from the child's other biological parent if they have parental responsibility. Read our remarriage name change guide.
Your new spouse does NOT automatically get parental responsibility just by marrying you.
Father not on birth certificate
If the father is not listed on the birth certificate and was not married to the mother, he likely does not have parental responsibility. In this case, only the mother's consent is needed.
Caution: If the father has since obtained parental responsibility through a court order or parental responsibility agreement, his consent IS required.
One parent is deceased
If one parent with parental responsibility has died, only the surviving parent's consent is needed. You may need to provide a death certificate when updating documents.
One parent refuses consent
You cannot legally change the child's name without consent from all parents with parental responsibility. Your options are:
- • Try to negotiate and reach an agreement
- • Seek mediation
- • Apply to family court for a "Specific Issue Order"
- • Wait until child is 16 (they can then decide themselves)
Cannot locate the other parent
If you genuinely cannot find the other parent after reasonable efforts, you may apply to court for permission to change the name without their consent. You'll need to prove you've made genuine attempts to locate them.
Important Considerations
Legal Consequences of Unauthorized Name Changes
Changing a child's name without required consent is a serious matter. It could be considered a breach of parental responsibility and may result in court action being taken against you.
Child's Best Interests
Courts always prioritize the child's welfare. Consider:
- • How the child feels about the name change (if old enough)
- • Impact on their identity and sense of belonging
- • Relationship with both parents
- • Practical implications (confusion at school, etc.)
Involving the Child
While children under 16 cannot legally consent to a name change, it's good practice to involve older children (typically 10+) in the decision and understand their feelings about it.
