Whether you can change your child's surname without the father agreeing depends on whether he has parental responsibility. If he does, you need his agreement or a court order. If he does not, the law does not require his consent, although there are still some practical things to know.
This page uses "father" because that is what most people search for, but the same rules apply to any parent with parental responsibility.
Does the father have parental responsibility?
A mother always has parental responsibility. A father has it if any of these apply:
- He was married to, or in a civil partnership with, the mother when the child was born, or married her afterwards.
- He is named on the birth certificate and the birth was registered in England or Wales on or after 1 December 2003.
- He has a parental responsibility agreement with the mother, or a court has given him parental responsibility.
If none of these apply, he does not have parental responsibility. A step-parent does not get it automatically either, even when married to the child's parent.

If the father has parental responsibility
You need his agreement. GOV.UK is clear that a child's name change needs the agreement of everyone with parental responsibility. Where a court order already sets out who the child lives with, the Children Act 1989 also forbids changing the child's surname without the written consent of everyone with parental responsibility or the court's permission.
If he will not agree, you can apply to the family court for a specific issue order using form C100. The fee is £263. GOV.UK says you must try to reach an agreement first, and most applicants have to attend a mediation information meeting (a MIAM) before the court will hear the case. The court decides on the basis of your child's welfare, and judges treat a child's surname as important, so a change is not granted just because one parent wants it.
Please do not make a deed poll for your child in this situation without his agreement or a court order. Organisations such as the Passport Office can refuse to act on it, and it can count against you if the dispute ends up in court.
If the father does not have parental responsibility
Then his consent is not legally required. If you are the only person with parental responsibility, you can make a deed poll changing your child's surname on your own.
Two practical points. Organisations may ask about the other parent, so keep the birth certificate handy to show he is not named on it, or that the birth was registered before December 2003. And a father without parental responsibility can still apply to the court himself, for example for an order to stop the change, so if he is involved in your child's life it is better to talk to him first.
Making the deed poll
The form on this page is already set to "My child". It uses the wording for a child's change of name, is signed by you as the parent, and asks you to confirm that everyone with parental responsibility agrees. It costs £19.99 and downloads straight away. If your child is 16 or 17, they can make their own deed poll instead; see changing your name at 16 or 17.
