yes she can
The mother can sign her name, not the father's name.
The biological mother, and father if known go on the birth certificate. If the father is unknown or disputed, tests can be done to confirm or exclude who it is. If you are married to someone who is not the father, then you can either put his name down and hope it is never questioned, put the real father's name and deal with the trouble, or not put any name at all.
The father can file for this change.
yes and maybe no Um, well the mother might get in trouble with the father. Because I don't think the father appreciated it, but I'm sure that this person is also right. She may not get in trouble, but I'm convinced the father probably didn't appreciate it.
Oh yeah. The biological father and mother are put on the certificate.

Not really. It depends on the situation.
It depends on the state. In some states, a father who is unmarried to the mother acquires legal rights by signing the birth certificate. In other states, signing the birth certificate conveys no legal right, and the father still must proceed with a legitimation or paternity proceeding in order to become the legal father.
answer is simple. GET A LAWYER
Yes, if he is the one who fathered the child. Father's do not typically sign the birth certificate though, although he can be named on it.
Here in the Philippines, a mother can not just name any person as the father of her child in the Birth Certificate. They will look for a marriage contract as their reference when you named your child under his/her father's surname. Or if not married, they let the father fill up the Affidavit of Acknowledgement/Admission of Paternity at the back of the Birth Certificate.
