Generally, the man on the birth certificate is the child's legal father, unless/until proven otherwise.
Nothing happens
yes
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.
Then you are still legally the father just as if you were genetically the father.
You are considered the legal descendant, for purposes of inheritance, of the parent who is listed on your birth certificate. However, someone supplied false information at the time of the recording of the birth and that issue may come up in the future. A court order could change the situation but until that time the birth certificate would control.
The same if he is listed on the birth certificate. NONE
If a father's name is on the birth certificate that does not make him a legal guardian, it makes him a father. The two are technically different. In this state a father can have guardianship without establishing it. A father can be forced to pay child support while a guardian can not.
If the father wants custody rights, this would be usable in court.
The are not always list yet still have court ordered rights.
If confirmed, the father. If not, the mother, though most likely the state. see link
Anybody who wants to can be responsible financially.If they don't want to, the fact that they're listed on the birth certificate is essentially meaningless. In many places, the mother can list whoever she wants as the father on the birth certificate; she's not required to actually prove it. Courts do not necessarily assume that it's correct, and particularly if the person listed can prove he's not the biological father, it would be a travesty of justice if they forced him to pay child support anyway.No, no, no. A man's name can be on the birth certificate only if he signs an acknowledgment of paternity. This makes him the child's father until/unless a court rules otherwise.
Only the biological father can sign his name, if that is what you mean. If the child is adopted the adoptive father can change it and sign his. If the mother sign his name or another man's name, it is fraud. The mother must always be listed on the birth certificate.
