Hamilton County Marriage License: Requirements, Validity, and Ceremony

A Hamilton County marriage license is issued by the Probate Court on the 10th floor of 230 East Ninth Street in Cincinnati. It costs $75, is valid for 60 calendar days, and both applicants must appear together in person. Ohio requires no blood test and no waiting period, so you can hold the ceremony the same day the license is issued.¹

Who Can Apply

Both applicants must be at least 18. Ohio allows 17-year-olds to marry only with juvenile court approval, and the other person cannot be more than four years older.² Neither of you can still be legally married to someone else, and Ohio prohibits marriages between relatives closer than second cousins.³

Residency Rules

If at least one of you lives in Hamilton County, apply here regardless of where in Ohio the ceremony will take place. If neither of you lives in Ohio, you can apply in Hamilton County only if the wedding itself will happen in the county. Ohio residents planning to marry in another state or country need to get their license from that jurisdiction instead.¹

What to Bring

A valid government-issued photo ID for each applicant, such as a driver’s license or passport.
Both applicants’ Social Security numbers.
An original or certified copy of each applicant’s birth certificate or birth record.
If either of you was previously married: the former spouse’s name, the date the prior marriage ended, and the case number and jurisdiction of the divorce or dissolution. If a former spouse died, bring the date of death.
The $75 fee. The court accepts cash, credit cards, and debit cards, but not checks. Credit card payments carry a small processing fee.

Where and When to Go

The Marriage License Office is at 230 East Ninth Street, 10th Floor, Cincinnati, OH 45202. Hours are Monday through Friday, 8:00 a.m. to 3:45 p.m., excluding holidays. The office closes at 3:45 rather than 4:00 to allow staff time to balance financial transactions, so don’t count on a last-minute arrival.¹

At the Counter

The Probate Court offers an online pre-application you can fill out before your visit. It saves time and helps confirm you have every required detail ready. Both applicants still need to appear together in person.¹

When you arrive, a deputy clerk pulls up your electronic data and checks it against your physical ID. If you didn’t pre-apply, you’ll fill out the application at a kiosk in the office. The clerk then administers an oath in which both applicants swear the information is accurate. Verify every spelling before you sign, because what you enter prints directly onto the license.

The whole process takes about 20 to 25 minutes, and you leave with the physical license in hand. Corrections after the fact cost $90.¹

How Long the License Is Good For

The license is valid for 60 calendar days from the date of issuance. If the ceremony doesn’t happen within that window, the license expires and you’ll have to apply and pay the $75 fee again. The ceremony must take place in Ohio for the license to be legally effective.¹

Who Can Perform the Ceremony

Ohio law authorizes several categories of officiants:

Any minister of a religious society or congregation within Ohio who holds a license to solemnize marriages from the Ohio Secretary of State’s office.
County court judges, municipal court judges, and probate judges.
The mayor of any Ohio municipal corporation.
A religious society, performing the ceremony in conformity with its own rules.

⁴

Verifying that your officiant is properly authorized is on you. If yours was ordained online, confirm with the Ohio Secretary of State’s office that they hold a current Ohio license before the wedding day.

After the Ceremony

The officiant must sign the marriage certificate and return it to the Probate Court within 30 days. Missing that deadline is a minor misdemeanor punishable by a $50 fine, so follow up with your officiant to make sure it gets filed.⁵

Once the court records the certificate, the marriage is part of the county’s permanent records, and you can order certified copies from the Probate Court. Most couples need a few for name changes, insurance updates, and benefits enrollment.

Changing Your Name

If you’re taking a new last name, start with the Social Security Administration. You can request a replacement card online or at a local SSA office; the new card generally arrives within 5 to 10 business days.⁶ Update Social Security first, because most other agencies want their records to match SSA before they’ll process a name change. From there you can update your driver’s license at the Ohio BMV and your passport through the State Department. If you have travel booked under your current name, hold off on the passport update until you’re back, since the name on your passport must match your airline ticket.
