You can change some information on a birth certificate by re-registering the birth.

You can:

  • add the natural father’s details 
  • show the mother and father of the baby as married or in a civil partnership

You can re-register a child at any age, and this can be done at any register office in England and Wales.

Re-register a birth application form

If you need more information, you can email us.

You can buy a copy of the new registration certificate after it’s been signed.

Adding the natural father

You can add the natural father’s details later if:

  • the natural parents weren’t married when the baby was born, and
  • the father didn’t attend the baby’s registration

Both parents will need to complete the re-register a birth application form and attend the re-registration appointment.

Showing the parents as married or in a civil partnership

If the natural parents have married each other since the birth was registered, the birth should be re-registered to accurately record the current legal status of the child.

Both parents will need to complete the re-register a birth application form. You will need to bring a copy of your marriage certificate to the appointment.

If you got married outside the UK

You'll need to get the authority to re-register the birth from the General Register Office. You'll have to submit your marriage certificate and the application to re-register a birth with them.
