Information for Parents who Subsequently Marry Each Other
If you were not married to each other at the time of your child's birth, and have subsequently married each other, there is a procedure which will allow you to add your date of marriage to your child's birth entry. This procedure is called re-registration.
Once you have successfully completed and submitted the necessary forms, this will allow the registrar to cancel the original birth entry and create a fresh birth entry which will include your date of marriage. There is no fee for the process, however if you wish, you can purchase a new birth certificate at a cost of £10.00 for up to one month after the date of re-registration. Thereafter the statutory fee of £15.00 for a certificate apply.
Application should be made to your local registration office.
