Re-register a birth

Skip to:

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 natural father after the birth and want their details on the birth record

    Natural parents have married after the birth

    Both parents must complete the application to ‘re-register a child’s birth following marriage of natural parents’ form.

    Once we receive this completed form together with supporting evidence, we can make an appointment for you.

    At your appointment you can buy a birth certificate with the updated details.

    Married abroad

    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.

    Natural parents are not  married

    Both parents must complete the application to ‘re- register a child’s birth and  add the natural fathers details’ form

    Once we receive this completed form together with supporting evidence, we can make an appointment for you.

    If one of you can’t attend the appointment, that person must complete 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

    At your appointment you can buy a birth certificate with the updated details.

    When the court decides who the father is - ‘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.
