Marriage licenses can be obtained at the County Clerks Office, usually in the county you wish to have the wedding in. For Public Licenses, you can marry anywhere in the state from which the license was obtained. For Confidential Licenses, you must have the ceremony in the county where the license was obtained.
Once the ceremony has been completed, your witnesses (with the public license only) and I will sign the license. The license will then need to be mailed back to the County in the return envelope provided by them at the time the license was acquired, or you can hand carry it back to them within 10 days of the ceremony.
