Can you change a birth certificate?
If you register a forename and then change your mind, you can apply to alter the birth certificate, provided the child was baptised in the new forename or the forename was in "regular use" within 12 months of the birth being registered.
Where a father is correctly named on the birth certificate, the surname cannot then be changed. The same applies where the parties were not married, but the father attended the registration.
Where the parents were not married at the time of the birth, they can re-register the birth to show the father's details and the child can take their surname, where they subsequently marry, or the father was not present at the registration process.
If a mistake was made when registering the birth, the person who registered the birth can apply to correct this.
If you need to make a change to your child’s birth certificate as set out above then see the guidance notes on the government website.
