Changing a birth record

If the parents were married after the child's original birth registration, you must make a new registration to show your child is a child of your marriage. To do this, the parents must re-register the birth so that a new birth record can be created to replace the original one.

This change can only be made once. After this, you can change a name by deed poll.

If the parents are not married – do not use form LA1.

If you need to change the child's last name

This can also be changed, if both parents agree. If the child is 16 or older, they must give their written consent before their last name is changed.

How to apply

You will need follow these 3 steps:

1. Download the application form LA1 from GOV.UK – or collect a paper copy from Croydon Register Office.
2. Complete the form – both parents must sign the form.
3. Hand in or send your completed form with the original birth certificate to Croydon Register Office.
