By court order for paternity. It was established legally i am not the fater. How can i sign away my rights or get released from a child that is not

   You will need to file an action to disestablish paternity.  However, to do s requires strict compliance with Florida Statute 742.18.   You mus allege via a sworn statement that newly discovered evidence has been revealed since you signed the birth certificate.  For example, you were tricked into signing the birth certificate. Even still, a court may deny the disestablishment because you signed the birth certificate.  This is definitely a tricky area where  an attorney can help.   Good luck, Cindy S.
