You can write to us to acknowledge you're the parent of a child if no other proof exists. We'll accept your written acknowledgement unless there's a reason to doubt it's correct, for example, if our records show another person listed on the birth certificate.
Gather your information
You'll need your own:
- IRD number
- current address
- contact details.
You'll need your child's:
- place of birth
- date of birth.
If this is for more than one child, give each child's details.
Write to us in myIR

- copy of a declaration made before the court that you're the child's parent, attaching this to a web message in myIR.
