Adding a father's name to a birth certificate

The form you fill in depends on whether

you marry or form a civil partnership with the nautral father after your child's birth was registered - you must re-register the birth by law
you’re not married or in a civil partnership but you want the natural father's name on the birth record

If you wish to change the child’s surname, it can be changed to the same as the mother, the natural father or any combination of the two as long as both parents agree to the change. Where the child is 16 years or over, their written consent will be required.
You cannot change a child’s forenames at re-registration.
New birth certificates can be purchased on the day of re-registration appointment.

Depending on the type of re-registration, you will need to complete an application form. Once completed, you will need to return it to Hounslow Register Office, Feltham Lodge. We will contact you to arrange a re-registration appointment.
