You may attempt to set aside the agreement by filing a motion with the court alleging undue influence, duress and/or fraud. If you decide to file, then you should do so promptly. There is limited time to file. If this is 1A divorce there is 120 days from the divorce hearing to act. If a 1B divorce then only 90 days from the divorce hearing to act.
