Always retain a copy of anything you sign. Please contact your (ex?) husband to obtain a copy and bring it to an attorney for advice on finalizing your divorce.
If there is a signed, settlement agreement that states the agreement is irrevocable you need to obtain a copy and move forward with finalizing your divorce. A properly executed settlement agreement can be used to prove up the terms of a divorce prior to the Final Decree of Divorce being entered with the court. Contact your lawyer and request that he/she obtain a signed copy from your spouse's lawyer.
