Depends on why you signed them away. If it was for temporary treatment you can but not if the child was adopted. When it comes to foster care. the court would have to be convinced the situation has changed and that you wont do it again.
If you sign over your parental rights in a court of law...you must go back and petition the court to regain your parental rights.
You didn't read what you were signing?
If you have custody and the father keeps the child with him without your permission you can call the police for kidnapping.
Not from that moment but you still owe if you owed prior to the signing away. Someone else paid for your child and should get their money back.
no
Not without the legal system involved. Not without the legal system involved.
No. You would be signing away your rights to visitation. A parent generally signs away their rights in preparation for a legal adoption.
Since you are the legal guardian she has to go to court to get them back. What happens there depends on the situation.
by "signing over rights" I persume you mean, terminating her parental rights and no, she is not obligated to pay child support, however, any accumulated back child support, or "arrears" is required to be paid, unless agreed otherwise. For this you would have had a prior order to pay support prior to the terminating of the mother's rights. When your rights to a child is terminated it is as if the child was never yours and your rights to the child, and obligation for the child are forever terminated.
You need a good lawyer and have to go back to court. Coercion is hard to prove. You have to try for the parental rights first but courts are not that keen on giving it back. They are scared you might do it again and they think about the child. Talk to a lawyer about your chances.
No as that would be considered child abandonment.
Sorry to say but no. It is a legal agreement.
yes u may
