Mercer County Overview
Mercer County Probate Court Info
The Mercer County Probate/Juvenile Court is at 101 North Main Street, Suite 307, Celina, Ohio 45822. Call (419) 586-8779 to reach them. Judge Matthew L. Gilmore presides over the court. Hours are 8:30 a.m. to 5:00 p.m. on Mondays, and 8:30 a.m. to 4:00 p.m. Tuesday through Friday. The Monday hours run an hour later than the rest of the week, which is a bit different from most Ohio probate courts.
One thing that makes Mercer County unique is that the Probate Judge serves as ex-officio Clerk of Courts. That means the court does its own indexing, filing, and docketing. There is no separate clerk's office for probate matters. Everything runs through one place, which can make things simpler when you are looking for records.
Both people must appear in person per ORC 3101.05. At least one must live in Mercer County. If both live out of state, the wedding must take place here.
What to Bring
You need a valid photo ID. A driver's license, state ID, or passport all work. You also need proof of your Social Security number. The court keeps the number on file but scrubs it from public records under ORC 3101.051. Your Social Security number will not show up on any copy of the marriage record that the public can see.
If either person was married before, bring a certified copy of the most recent divorce decree. You need the date, the case number, and which court granted it. If a former spouse passed away, a certified death certificate is needed instead. The application asks for your name, age, residence, birthplace, parents' names, occupation, and the name of your officiant. False statements are punishable under ORC 2921.13 as falsification.
Note: The marriage license application form is available as a PDF on the Mercer County website, so you can review it before your trip to the courthouse.
Fees and License Validity
Call (419) 586-8779 to confirm the current fee. Mercer County's copy fees for public records are $0.25 per page under the court rules. Ohio has no waiting period for marriage licenses. You can pick it up and use it the same day. That rule has been in place since 2001.
The license expires after 60 days under ORC 3101.07. The expiration date is printed on the license in large type. If 60 days pass without a ceremony, the license is void and you start over. There are no extensions or exceptions. Certified copies of marriage records have a small per-copy charge that you pay when you request them from the court.
Authorized Officiants
Under ORC 3101.08, these people can officiate a wedding in Ohio:
- Ordained or licensed ministers registered with the Ohio Secretary of State
- County and municipal court judges
- Probate judges per ORC 2101.27
- Mayors of any Ohio city
- Religious societies following their own church rules
The officiant files the signed marriage certificate with the Mercer County Probate Court within 30 days. ORC 3101.13 sets that rule. Missing the deadline is a minor misdemeanor with a $50 fine. Each license comes with a pre-addressed return envelope.

Mercer County has some of the oldest marriage records in western Ohio, going back to 1824. The Wright State University Libraries hold Mercer County marriage records from 1824 to 1984, along with marriage consent records from 1829 to 1928. That is a huge collection for genealogical researchers. The Ohio Department of Health has a statewide index from 1949 forward. The Ohio History Connection may also have archived Mercer County records.
Getting Certified Copies
Contact the Probate Court at (419) 586-8779 or visit the courthouse at 101 North Main Street. You can also send a request by mail. Include the names of both spouses and the approximate marriage date. Facsimile filings are accepted by the court, so you may be able to fax a copy request as well. Records can not be removed from the Clerk's Office without the court's consent.
The Ohio Legal Help website has guidance on how to work with probate courts across the state. It covers what forms you might need and what to expect during the process. This free resource is kept up to date by legal aid groups.
Note: Facsimile filings are accepted, but confirm with the court whether fax requests for certified copies are allowed.
The Wright State University Libraries hold a large collection of Mercer County marriage records from 1824 to 1984. They also have marriage consent records from 1829 to 1928, which show parental approval for younger applicants in that era. If you are doing family research, those holdings can fill in gaps that the Probate Court may not have readily on hand. The Monday hours at the court run until 5:00 p.m., which gives you an extra hour compared to the rest of the week. That can be helpful if you work during the day and need to stop by after 4:00 p.m.
