Yes, if/when paternity is established.
Yes, but then you would lose your rights as the child's legal father.
Under UK Child Support law, the CSA would order the test and if he is proved to be the father he would pay for the test after the event.
It depends upon the state in which the minor child resides. The majority of U.S. states have a statute of limitations concerning the filing and awarding of child support monies. Aside from that issue, if the male who is named as the father by the biological mother does not voluntarily accept responsibility a paternity test will be required before child support matters are pursued. Whether or not the "father" can be ordered by the court to take such a test might also become a complicated legal issue. FYI, generally the law presumes whomever is named on the original legal birth certificate is the father of the child. If said person made no objection to the designation at the time of the birth it is unlikely that a court would hear a motion to take action against another the now alledged father.
Too many people involved. Leave the birth certificate as it is. Let the biological father continue to pay child support. If the current man marries you and wishes to adopt the child, then that is another matter. Seek legal advice before doing anything to change the birth certificate. No. This would be fraud unless the child is adopted by your boyfriend.
So what relationship are you to the parent or the child? If you were married when the child was born, you are assumed to be the father. Unless someone else is listed on the birth certificate, you're going to be expected to support the child.
If the father wants custody rights, this would be usable in court.
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.
If you are adopted, your biological father has no legal standing. And there is no requirement that any parent sign a wedding certificate. If you are underage, you may need signatures to obtain the marriage license and it would be the adoptive parent that would have to sign.
This question is a complicated one in that the laws of paternity do not necessarily establish the biological father as the father for child support purposes but rather look to the circumstances surrounding the case. Your husband is what is known as a presumed father, which is essentially a man that was married to the mother when the child was born, legally agreed to be the father of his wife's child (by signing the birth certificate, and has acted and behaved as the child's father. You cannot receive child support from both the presumed father (if he is still your husband) and the biological father (assuming he admits to being the father) and a court would likely determine your husband to be the father for purposes of child support.
A child's first connection would be their parents (mother and father). Their next connection would be their siblings (brothers or sisters) if any.
If what is meant by the term "legitimate" pertains to whether the father is responsible for supporting the child, then the answer would be yes. Once paternity has been established either by the signing of the birth certificate, a declaration of parentage or by DNA testing the father can be held responsible for support of the child and likewise he is entitled to petition for custodial or visitation rights.
Not if the parents are not married. The father would need to file a court action to establish paternity, a child visitation schedule and a child support order.
