Re-registering a birth

Re-registering usually takes place because:

  • the parents married after the child’s birth
  • the child was originally registered without father’s details, and both parents have since decided they would like them included

Both mother and father usually need to be present to re-register the birth if the father’s details are being added. Either parent can attend to re-register the child if are doing so because they married after the child was born.

When you come to re-register, you will need to bring:

Send the relevant form to us. If you no longer live in Doncaster, contact your local register office and ask about re-registration by declaration.

A full copy certificate following re-registration will contain the new name and costs £11.



You can change a child's first name at any time providing a new name was given in baptism or by regular use within 12 months of the birth being registered. This costs £40 plus £11 for the new birth certificate.

  • if your child was baptised in a Christian church, the vicar needs to complete the relevant form
  • if not, you need to complete this form (which can be obtained from the Register Office)

A full copy certificate following changes to first name or adding a middle name will show the original name and the new name.



If you spot a mistake in the original birth registration the person who registered the birth needs to prove that an error exists. Correction of any mistake may incur a charge of £90.

If the error was spotted within 14 days, write a letter to our registry office stating what the error is and how it was made. If there has been a longer time gap, you will also need to provide documentary proof that you are bringing up the child in a different name. This evidence needs to be from earliest infancy and could be in the form of a clinic card, NHS medical card or bank book.

Your letter, and any documentary evidence where applicable, will then be submitted to the Registrar General's office for consideration.
