I have a marriage license,what do I need to do to get married in the courthouse

What do you do to get married at the courthouse if you already have your license

The clerk that you got the license from would give you the details. As to time, if appointments are needed. So merely call them back in the morning and ask them.

Each courthouse has its own rules, here in Cobb County they do it every day at a certain time, all couples wanting to be married stand outside the judges office and go in one couple at a time and get married in the office.
