No appointments are taken, so you should check the court’s website or call to confirm its hours. Marriages and civil unions are also performed at the suburban municipal district courthouses. Times and restrictions vary, and some are by appointment only, so call in advance.
After the marriage ceremony occurs
The officiant performing the ceremony must complete the bottom portion of the marriage license and mail or deliver it to the Clerk's office.
You may obtain a copy of your marriage certificate upon request.
