Marriage License
Montgomery County runs an online pre-application portal. Filling it out before your visit cuts your time at the counter significantly, but both partners still have to appear together in person to finish the application.
What to Bring
Each applicant needs a valid government-issued photo ID, such as a driver’s license, state ID card, or passport. You also need to know your Social Security number. The application asks for each person’s name, age, residence, place of birth, occupation, father’s name, mother’s maiden name, and the name of the officiant.2Ohio Legislative Service Commission. Ohio Revised Code 3101.05 – Application for Marriage License
If either partner was previously married, expect to give the names of former spouses, any minor children from those marriages, and the jurisdiction, date, and case number of the divorce. Bring a certified copy of the final divorce decree, or a death certificate if a former spouse is deceased. Without that documentation, the clerk may not be able to issue the license the same day.
A clerk verifies your documents and both applicants swear under oath that the information is true. False statements can carry legal consequences or invalidate the marriage.
Who Can Apply
Both applicants must be at least 18 to apply on their own.3Ohio Legislative Service Commission. Ohio Revised Code 3101.01 – Persons Who May Be Joined in Marriage A 17-year-old can marry only with juvenile court approval, and if only one partner is 17, the other cannot be more than four years older. No one under 17 can marry in Ohio under any circumstances.4Ohio Legislative Service Commission. Ohio Revised Code 3101.02 – Marriage of Minors
Ohio also prohibits marriage between close relatives (second cousins or nearer) and between anyone who still has a living spouse from a prior marriage that has not been ended by divorce or annulment.
Where You Can Marry With a Montgomery County License
Residency changes where you apply and where you can hold the ceremony. If at least one partner lives in Ohio, you apply in that person’s county of residence. A couple with one partner in Montgomery County files in Montgomery County no matter where the other partner lives, and Ohio residents can then take that license and marry anywhere in the state.2Ohio Legislative Service Commission. Ohio Revised Code 3101.05 – Application for Marriage License
If neither partner is an Ohio resident, the rule tightens. You apply in the county where the ceremony will happen, and the wedding must take place inside that same county. An out-of-state couple who gets a license in Montgomery County has to marry within Montgomery County.1Montgomery County, OH. Marriage License
How Long the License Is Valid
The license lasts 60 days from the date it is issued.1Montgomery County, OH. Marriage License If you don’t hold the ceremony within that window, the license expires and you have to start over and pay the fee again. There is no extension or renewal. Since Ohio has no waiting period, you can also marry the same day you pick it up.
Who Can Perform the Ceremony
Ohio law authorizes several categories of officiant:5Ohio Legislative Service Commission. Ohio Revised Code Chapter 3101 – Marriage
- Ordained or licensed ministers who hold an active license from the Ohio Secretary of State.
- County court, municipal court, and probate judges, within their jurisdiction.
- Any mayor of an Ohio municipality, anywhere in the state.
- The current governor or any former governor of Ohio.
- A religious society that solemnizes marriage under its own rules, without a single designated officiant.
Judges and mayors do not need a separate license; their authority comes from the office. Ministers, including those ordained out of state, must register with the Ohio Secretary of State before performing a ceremony.
Do You Need Witnesses?
Ohio does not require witnesses. Some probate courts print extra signature lines on the license, but those lines are optional and have no effect on whether the marriage is legally valid. Only the two partners and the officiant have to be present.
Getting the Marriage Recorded
After the ceremony, the officiant signs the marriage certificate and is responsible for returning it to the Montgomery County Probate Court within 30 days.6Ohio Legislative Service Commission. Ohio Revised Code 3101.13 – Certificate of Marriage That step is what officially records the marriage. Until the certificate reaches the court, the marriage is not part of the county registry, which can hold up a name change, insurance updates, or a joint tax filing.
If your officiant is casual about paperwork, follow up within a week or two. Call the Probate Court at 937-225-4400 to confirm that the certificate has been received and the marriage recorded.
