The relief you ask for it not simple since after the passage of time, there is no authority for the court to order genetic tests and your ex husband is presumed to be the legal father even if he is not the biological father. Your best option is to file a Petition to establish non-paternity and if it is not opposes (or if the ex husband cooperates), you may get a Judge to sign a Judgment that your ex husband is not the father and that the birth certificate can be amended.
