Paternity

Married Couple in the state of Wisconsin, the wife had an affair and got pregnant. Her husband is not the father because he had a surgical medical procedure to not have children. He signed the birth certificate when the child was born. After 4 years the wife had a paternity test with the child biological father and separated with her husband. The biological father then started to see the child on a regular basis and that child calls him daddy. What legal right does that biological father have to add his name as father on the child’s birth certificate?

I Received a phone call last week of a woman claiming to be my child she is now 29 years old. She told me she lived thinking another man was her father until the age of 13 then she was told I was the father, I have only minor recollection of the woman ( I was 17 at the time) she claims is her mother and can only put myself with in a 4 month window. I saw her photo on facebook and she does have a remarkable resemblance of my sister. I introduced her to my family as my possible daughter and gave her family information. My mother then told me of an email she received a few days prior to my revelation threatening court action. I agreed to a paternity test. My question is what legal action can she take if the test comes back positive.

What form do I need to establish paternity of my child with my girlfriend so I will have legal rights to a shared custody?

My son is 6 months old, me and his dad and I don't get along, I live in Fl and he lives in SC. His name is not on the birth certificate. He used to help me financially but he went to jail for 4 months because he got 4 DUI's. I do have one DUI but that was like 2 yrs ago but I've never been to jail. Now that he is out, he doesn't have a job and is not helping me financially. He is threatening me to take me to court not to get custody, but he wants the baby to go stay with him for few months but I tell him he is too little. What type of visitation can he get? Am I obligated to have any type of communication with him?? We don't get along and I don't like how he talks to me. He has hit me before but I don't have any proof. I don't want to take my son out of his life but I would like to know how can he see the baby without taking him to other state, and I'm tired of him trying to make me talk to him when I just can't get along with him.

My daughter got pregnant while going to college in Utah. The father asked her to abort or put the child up for adoption. She chose to have the baby and returned to Utah with the baby for school. She lets him see the child on Sundays because his parents mostly want to see the child .. now he is threatening her with court to see the child every other weekend giving the reason of being to plan for his social life and to get his mother off his back. What should my daughter do to protect herself? Her and the child are still residence of NH and she does not want to be forced to stay there after school.
