What it means for a change of name
For a child under 16, everyone with parental responsibility has to agree to a new name. HM Passport Office’s guidance says it won’t accept a child’s change of name unless they all have, and that without a court order it issues the passport in the child’s original name.

If a court has made a child arrangements order saying who the child lives with, the Children Act 1989 goes further: nobody can cause the child to be known by a new surname without the written consent of everyone with parental responsibility, or the court’s permission. The same applies under a special guardianship order or a care order. Children Act 1989, section 13
If you’re the only person with parental responsibility, you can sign your child’s deed poll on your own. The Passport Office may write to ask you to confirm that you have sole responsibility.
Signed by everyone with parental responsibility, our child’s deed poll is backed by our acceptance guarantee for the Passport Office, HMRC, the NHS and other UK public bodies.
