Who must consent to the child’s name change?
For a child aged 0 to 15, HM Passport Office says everyone with parental responsibility or legal guardianship must consent to the change of name before it will issue a passport in that name. If consent is not supplied, a court order specifically allowing the change may be required. The consent can be shown by everyone signing the deed or by the other parent applying for the passport in the new name using the signed deed, subject to HMPO’s checks.

HM Passport Office applies its consent approach to all child name changes, not only surnames. Check who holds parental responsibility and tell the Passport Office about any relevant court order.
