You’ll have the option to switch back to your premarital surname after the final hearing or trial. The court will add your preferred last name on your divorce judgment if you specify it throughout the divorce proceedings. The judge will also inquire in court as to whether your goal in taking back your previous last name is to mislead creditors, escape legal trouble, or even declare bankruptcy. You will need the Gold Seal Final Divorce Decree in order to update records like your driver’s license and social security card.
