Only if his paternity of the previous children is established.
No. If your present husband is the father of the children of his previous marriage and is the custodial parent he would have to sue his ex-wife (the children's mother) for support.
If the father is unknown, you can't file for support.
No. But, the child/children of the deceased may have a claim to assets of their father's estate.
The father can file for this change.
No, the father must support his previous child. You knew this when you had a new child with him.
This arises often in the case of adoptive children, foster children, or re-marriages. If you wish to honor your step-father as your "Dad" yes it is okay to do so.
Not really. It depends on the situation.
No. However, if the alleged father has signed the birth certificate, he is acknowledging that the child is his. There are steps to take in order to be taken off of the birth certificate and relieved of the obligation of child support, including a paternity test and an amendment to the birth certificate.
Yes you can leave the spot blank for instance a father. I am a teacher and have many children in my class who have no father listed on their birth certificate.
Yes and he still have to pay whether he signs the birth certificate or not.
You don't say which of the parents that are incarcerated but their rights to the child comes first. If the father is not in the birth certificate and he has not established paternity to the court so he can petition for visitation or custody and also pay child support, there is nothing that legally says he is the father. Then the maternal grandmother would have a better chance. If the father is not in the birth certificate but he has established paternity to the court so he can petition for visitation or custody and also pay child support, the chance should be equal.
Maryland does not have that specific provision, but all child support is rebuttable.
