You have 10 days after the baby is born to
- choose a name,
- fill out a birth certificate, and
- file the certificate with your local birth registrar. (If you fill out the certificate at the hospital, the hospital will file it for you.)
The hospital may ask you to fill out the birth certificate before you leave. But if you need more time, you do not have to decide at the hospital.
If you do not choose a name within 10 days, the state will make a birth certificate for “baby boy” or “baby girl” with the mother’s last name.
Later, you will have to file legal forms to change it to the name you want.
