Neither ... the " father " has to pay owed child support only when there is an existing case open and ordered to pay said support by a family court judge ... And subsequently has not met all payments if any at all ...
If the man sues you after he's been paying for your child, yes the judge can think he should get his money back.
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.
The father can file for this change.
Unlikely. Your husband is the legal father of the child.
Yes, if/when paternity is established.
Yes and he still have to pay whether he signs the birth certificate or not.
Not really. It depends on the situation.
Yes, but paternity must be established first.
Yes, but then you would lose your rights as the child's legal father.
The man who signed the birth certificate is the child's legal father until/unless a court rules otherwise, and can be made to pay support.
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.
Depends. Even if he is not on the birth certificate he can still have a court ordered visitation and pay child support. In that case she needs both his and the courts permission.
Your spouse may adopt the child but the court will have to serve notice of that proceeding to the biological father.
