I think the easiest way to do this is to file a paternity action. With that said could you please clarify one thing? Mom is residing in Nevada..is she residing with the grandprents?
After reading some articles on the web I believe that even if I was to get a paternity action, my name is on my child's birth certificate. I found the following information:
State of California:
IMPORTANT! Once paternity or parentage is established, it can be difficult or impossible to undo — even if DNA/blood tests later show that the father is not the biological parent of the child.
After parentage is established, each parent has:
• An equal responsibility to support the child, and
• An equal right to custody of the child.
Challenging the Declaration of Paternity in court
A Declaration of Paternity may be challenged in court only in the first 2 years after the child's birth:
• By using blood and genetic tests that prove the man is not the biological father; OR
• By the father or mother proving that he or she signed the form because of fraud or because he or she was forced to sign it.
I have no other choice but to seek legal action, it's just a shame that a mother can put their own child through this. The mother is residing in the state of Nevada married and has another child of her own; while my daughter is living in Arizona with the grandparents, (mother's parents).
