Though this is not necessarily something done on the wedding day, it is crucially important that the completed marriage license be returned to its issuance office ASAP.
Returning the marriage license is usually done by mail. Some states do have specific laws requiring the marriage license be returned by the couple or the officiant.
The marriage license issuance office will include specific instructions on how the marriage license should be returned after the wedding. Make sure to follow those instructions.
If you have further questions on how to return the marriage license in your locality, we recommend that you contact the marriage license issuance office.
