Knox County Probate Court

The Knox County Probate Court in Mount Vernon is where all marriage records are kept. The court issues new licenses and stores the completed marriage certificates after the ceremony. This is the only place in the county that can issue a marriage license under Ohio Revised Code Chapter 3101.

Both people must come to the court in person to apply. You each need a valid photo ID. If either person was married before, bring the divorce decree or death certificate from the prior marriage. There is no waiting period in Ohio, so the license can be issued the same day you apply. It stays valid for 60 days. The court charges a fee for the license and a smaller fee for certified copies of existing records, usually around $2 per copy.

You can request these by mail. The Records Center provides application forms for the bride and groom that are available for download, which makes things easier if you want to prepare before your visit.
