Re-register a birth

  • Births, deaths, marriages and nationality

You must re-register your child’s birth if:

  • you want to add the natural father’s details to the birth record
  • you have married your child's father after the birth and want their details on the birth record

If you want a new birth certificate you’ll have to order one, you don’t get one automatically when you re-register the birth.

Parents have married after the birth

An ‘Application for re-registration following parents’ marriage’ should be completed by both parents. Once we receive this completed form together with supporting evidence, we can make an appointment for you.

If you were married abroad your Re-Registration application will be sent to the General Register for authorisation, once this has been authorised we will make an appointment for you to Re-Register your child.

Parents aren’t married

If you want the father’s name on the birth record, an 'Application for the re-registration of a child's birth' form should be completed by both parents. Once we receive this completed form, we will make an appointment for you.

If one of you can’t be there, that person also needs to fill in a ‘Statutory declaration of acknowledgement of parentage’ form. This declaration must be made before a justice of the peace, magistrate, commissioner for oaths, practising solicitor, notary public, licensed conveyancer, authorised advocate or authorised litigator, by one parent only.

If there’s been a ‘Declaration of Parentage’

A Declaration of Parentage is when the court decides who the father of a baby is. You don’t need to do anything to change the birth record if there’s been a Declaration of Parentage made by a court. The court will tell the General Register Office and the birth will be re-registered. You’ll need to order a new birth certificate if you want one.
