I'm the biological father and want to be the legal father of my son
Hi,I just found out that I am the biological father of my 2 yr. old son through DNA testing.my son's legal father right now is his mother's ex live in partner.he just found out too that he's not the real father of my son.my son and the mom and the legal father is in New Jersey right now and I just moved here in California because of work.now, I want to change my son's last name to mine because I want to bring him here in California and live with me, with my parents and my sis and bro because the mom is going to lose her job and she doesn't have any savings and she doesn't have any relatives here in the united states.the mother and the legal father are illegal aliens here in the united states but the legal father has relatives here.the mom is cooperating with me but the legal father wants me to pay him $15000 for all the things that he spent for my son in 2 yrs and for lying to him that he was the father of my son in order for him to cooperate with us.but its not me who lied to him,the mother was the one who lied about it.I just found out too.so how can I possibly change my son's last name to mine and be the legal father without the legal father's cooperation?I have the copy of the DNA test result though.im really worried about my son and his future.someone help me p l e a s e
