Birth re-registrations

Re-registrations are required when:

  • the mother marries the biological father of the child after the birth was registered.
  • the father's name was not on the birth certificate, but the mother now wants this added

To apply to re-register a birth, please complete one of the downloadable forms below. You will be instructed on whether your form should be sent to our local register office, Langton's, or sent to the General Registration Office. Once your application has been authorised, you will be provided with a unique reference number which you will need to book you re-registration appointment.

It is in the best interests of the child (and a legal requirement) that the birth be re-registered where necessary - failure to re-register may affect the legal rights of both child and parents.


Re-registration after marriage

For use when the biological parents of a child have married each other since the birth occurred. Even if the father's details were originally entered in the birth register, and even if the child has the father's surname. If you are re-registering due to the parents marrying and one of the parents can't be there they will need to fill in a Statutory declaration of acknowledgement of parentage and post it to the General Register Office.

Re-registration to add the biological father's details

For use when wishing to add the biological father's details to a child's original birth registration. Applicable if the original registration does not show any of the father's details and where the biological parents were not married to each other when the child was born and have not married each other since
