Union County Booking Reports
Union County booking reports are kept by the sheriff's office at 221 W. 5th Street in Marysville, Ohio. Sheriff Jamie Patton runs the office and the county jail at the same location. Union County also uses the Tri-County Regional Jail in Mechanicsburg, which serves Champaign, Madison, and Union counties. All booking data is public under Ohio law. You can look up current inmates on the sheriff's website or through VINELink. This page covers how to find Union County arrest records, jail roster data, and court records tied to local bookings.
Union County Overview
Union County Sheriff and Jail
Sheriff Jamie Patton heads the Union County Sheriff's Office. The main office sits at 221 W. 5th Street, Marysville, OH 43040. You can call 937-645-4110 for general questions. The fax line is 937-645-4117. The county jail is at the same address, and you can reach jail staff at 937-644-2955. This is a full-service jail that holds people on charges from minor misdemeanors up through serious felonies. If you need a booking report that is not on the website, the office can pull it from their records system during normal business hours.
The Union County Sheriff's Office website is where you start for most booking report searches and jail-related info.
The site gives you access to the inmate roster, general contact details, and links to other services the office provides. It loads on both desktop and mobile without much trouble.
Union County books people on all kinds of charges. Drug cases, OVI, theft, domestic violence, and assault are the most common arrest types. Each booking creates a record with the person's name, date of birth, charges, bond amount, and a mugshot in most cases. These records stay on file and can be pulled up by anyone under Ohio's public records law. The sheriff's office does not charge a fee for basic booking record lookups.
Tri-County Regional Jail
Union County is one of three counties that use the Tri-County Regional Jail. The facility sits at 4099 State Route 559, Mechanicsburg, OH 43044. Champaign County and Madison County also send inmates there. The jail phone number is 937-834-5000. Some people arrested in Union County end up at this regional facility instead of the county jail in Marysville. It depends on the charge type, bed space, and other factors the sheriff's office weighs at the time of booking.
The Tri-County Regional Jail website has a section for Union County inmates specifically.
You can check this page to see if someone from Union County is being held at the regional facility. The site lists inmates by county, so you can filter results to just Union County bookings. If you cannot find someone on the Union County sheriff's roster, check here next.
Having two jail options means booking reports for Union County can exist in two places. Always search both the county jail roster and the Tri-County site to get the full picture. The regional jail has its own booking process, and records from there are also public under Ohio law. You can call 937-834-5000 to ask the regional jail staff about a specific inmate or request older booking records. Response times vary, but they are generally helpful with basic lookups.
Union County Inmate Search
The Union County Sheriff's Office posts an inmate roster on their website. You can check it at unionsheriff.com. The roster shows people currently held in the Union County jail. Each listing includes the inmate's name, charges, booking date, and bond info. There is no cost to search. You do not need to sign up for an account.
The roster is the quickest way to check Union County booking reports for recent arrests. It works best for finding out if someone is in custody right now. For the most up-to-date info, you can always call the jail at 937-644-2955 and ask staff directly. Phone calls get you real-time data that the website might not reflect yet.
VINELink is another tool you can use. It tracks custody status changes for inmates across Ohio, including Union County. You can sign up for alerts that tell you when someone gets released or transferred. VINELink is free and run by the state. It is especially useful if you need to keep tabs on a specific person over time rather than just checking once.
If you want older records or a booking report from a past arrest, you need to file a public records request. You can do this in person at the sheriff's office, by mail, or by fax. Under ORC 149.43, all booking reports are public records. The office must give them to you in a reasonable time. They cannot ask why you want them or make you show ID.
Note: Union County inmates may be held at either the county jail in Marysville (937-644-2955) or the Tri-County Regional Jail in Mechanicsburg (937-834-5000). Check both locations.
Union County Court Records
The Union County Court of Common Pleas handles felony cases that start with a booking at the county jail. The courthouse is in Marysville. Misdemeanor charges may go through the Marysville Municipal Court. When someone gets booked, the case moves through the court system from arraignment through trial or plea deal. Court records show everything from the initial charge to the final outcome. You can request these records from the clerk of courts office at the courthouse.
Ohio splits county courts into divisions. The General Division takes felony cases and big civil suits. Domestic Relations handles family law. Juvenile deals with minors. Probate covers estates and guardianships. For Union County booking reports that lead to criminal charges, the General Division is the one to check. Most serious arrests end up there.
The Ohio Courts portal gives statewide access to court data and can help you track Union County cases that have moved through the system or been appealed to the 3rd District Court of Appeals.
Court records and booking reports are separate things, but they connect. A booking report tells you someone was arrested and what they were charged with. Court records show what happened after that. If you need the full story on someone's case in Union County, you want both sets of records. The clerk's office can point you to the right files once you have a name or case number.
State and Federal Resources
State tools can fill gaps that the local roster does not cover. The ODRC Offender Search tracks anyone who has been moved from the Union County jail to a state prison. This is useful when someone was booked locally but later sentenced to serve time in a state facility. ODRC records include the person's current location, sentence length, and projected release date. The search is free.
VINELink handles custody alerts for all Ohio counties. You register with the person's name or inmate ID and get notified when their status changes. It covers releases, transfers, and escapes. The system works for both the Union County jail and the Tri-County Regional Jail.
For federal cases that originate in Union County, the U.S. District Court for the Southern District of Ohio has jurisdiction. Federal booking records are handled separately from county records. You can search federal cases through PACER, though that system does charge a small fee per page. Most Union County arrests stay at the county or state level, so you will only need federal records in rare situations involving things like federal drug charges or immigration cases.
The Ohio Attorney General's office keeps a database of registered offenders and also handles complaints about public records access. If the Union County sheriff's office denies your request or takes too long, you can file a complaint through the AG's office. They have a mediation program that resolves most disputes without going to court.
Union County Records and Ohio Law
Ohio has strong public records laws. ORC 149.43 states that all records kept by a public office are open to the public. That covers Union County booking reports, arrest logs, jail records, and mugshots. You do not need to live in Union County or Ohio to request records. The sheriff's office must respond in a reasonable time. Courts have generally said a few business days is reasonable for straightforward requests.
There are some limits. Social Security numbers get redacted. Sealed juvenile records are off limits. Certain victim information may be held back. But the vast majority of booking data is available without restriction. You can ask for paper copies or electronic files. The law covers both.
If a records request gets denied, you have options. You can appeal to the sheriff's office first. If that does not work, the Ohio Attorney General has a mediation program. As a last resort, you can take the matter to court. Ohio judges have a long track record of siding with the public on records access cases. The county cannot charge unreasonable fees for copies either. Standard copy fees are a few cents per page, and electronic records are often free.
Union County is a smaller county, and the sheriff's office tends to handle requests without much hassle. Walk-in requests at 221 W. 5th Street in Marysville are usually processed on the spot for basic booking records. More detailed requests that require pulling old files from storage may take a day or two.
