I am a single mother to an infant son. I dated his father briefly (6 months) and we had gone our separate ways by the time I found out I was pregnant. I did share the news with him and gave him the option to be involved or not... but I did not feel it was my place to make the decision for him by not telling him. He said that he had since reconciled with his ex-fiance and he would rather not be involved. However, a major curve ball was recently thrown at me when to my GREAT surprise I found out he has been married since 2005! I have actually spoken directly with his wife who now knows about his extra marital affairs and his son. He still claims he wants nothing to do with his son and I have not spoken to either one of them for several weeks and as much as I just want to carry on as if nothing has happened... I fear that left unaddressed, in the future there will be custody battles in the event something should happen to me. Even though he is not on the birth certificate (in California if you are an unmarried parent the father has to sign a declaration of paternity for his name to be listed as the biological parent) what rights does he have should something happen to me? My will has left my son with a legal guardian and funds have been established to cover both my son and his named caregiver in the events something should happen to me. Will the state automatically track down the father? (on all my state paperwork I listed the fathers name) Also what complications will occur should I marry and my husband want to adopt my son?
I guess in a nut-shell what I would like to know is... Should I take the legal steps/precautions to have the father terminate/relinquish all rights? Which he had previously agreed to do... This would entail him filing a declaration of paternity, then I would file a petition for custody. This doesn't mean I would deny visitation should he ever change his mind... I just want to insure that there are not an future custody obstacles in the arenas of future adoption and in the events I should pass.
Thank you for your time.
