What if I am married but I have a baby with another man?

You can get it from the Department of Revenue (DOR) or from the Probate and Family Court.

The form says that he is not the father of your child. If your husband does not sign the form, then legally he is the father and he has to support your child.

Both you and the biological father of your child need to sign a "Voluntary Acknowledgment of Parentage" form. You can get this from from the Registry of Vital Records or from the clerk in the city or town where your child was born.

File the Affidavit of Non-Paternity and your child’s birth certificate at the office of the city or town clerk in the city or town where your child was born.  

If you want the biological father's name on the birth certificate, you first need to

1. file the Voluntary Acknowledgment of Parentage with the Probate Court
2. get a certified copy from the court
3. file the certified copy of the Voluntary Acknowledgment of Parentage at the office of the city or town clerk where your child was born

If your husband will not sign the Affidavit of Non-Paternity, talk to a lawyer. You may be able to get some information from a Court Service Center, but this is a complicated situation. You might need to get a lawyer.
