Signing over parental rights
Long story short, I got pregnant by a man I wasn't in a relationship with. I met my husband in early pregnancy and we got married. He's taken my daughter in as his own for the last 2.5 years. Her biological father wants nothing to do with her.
In the state of California, if you're married, the husbands name has to be on the birth certificate, so that's what we did.
I am wondering if it would be necessary to have the bio father sign over his rights to myself and my husband, so we can go through with a formal adoption. Or, does he already have no rights since he's not on the birth certificate? I'm just worried that he'll be able to step in, in the future, with a dna test.
Input and advice would be appreciated.
