Paternity

My son's wife is in prison for a drug conviction. They have 5 children together. The oldest child was born before they married and the mother did not list my son as the father, otherwise unknown. What do we need to do to protect my grandson while his mother is in prison? And what steps do we need to take for my son to be listed as the father as he has raised him since he was 4 months of age, he is 14 yr-old?

i am pregnant with my third child. each child has a different father: however, the father of child number two may insist the child is his even though the rightful father's name will be on the birth certificate when the child is born. i do not live with this baby's father and will not be seeking support from him. i am worried that the father of my second child will assume that the new baby is also his despite the birth certificate. he lives in california and we do share custody of my second child. can he file a paternity suit concerning this third baby despite the birth certificate indicating the real father?

If a new single mother requires a former friend, who is pursuing legal custody of her child to prove paternity, who is required to pay for the testing if it proves positive?

Filing for custody of a minor by the father. 18 month old/father is named on the birth certificate

My husband was married 14 years ago to another woman. This other woman became pregnant, claimed the child belonged to another man and then married the other ma beofre the baby was born. Now, after 14 years, she is claiming the child is actually my husband's. We live in Tennessee. Is it possible for her to be awarded back child support as well as future child support for this child fromy my husband.?
