Re-register your child’s birth to add the natural father’s details to the birth record.
The form you fill in depends on whether:
you marry or form a civil partnership with the natural father after your child’s birth was registered - you must re-register the birth by law
you are not married or in a civil partnership but you want the natural father’s name on the birth record
Take the completed form to the register office. If you are not married or in a civil partnership and one of you cannot be there, that person also needs to fill in a ‘Statutory declaration of acknowledgement of parentage’ form and post it to the General Register Office.
Getting a new birth certificate
If there is been a ‘Declaration of Parentage’
A Declaration of Parentage is when the court decides who the father of a baby is. You do not need to do anything to change the birth record if there has been a Declaration of Parentage made by a court. The court will tell the General Register Office and the birth will be re-registered. You will need to order a new birth certificate if you want one.
