Butler County Genealogy Records

Butler County genealogy records date back to 1803 when the county was carved from Hamilton County. The county seat is Hamilton, and most vital records, court files, and land documents are kept at the courthouse at 315 High Street. If you are tracing family roots in southwest Ohio, Butler County holds a deep set of marriage, birth, death, probate, and land records across several offices. This guide walks through the key record sources, how to get copies, and where to look for hard-to-find genealogy files in Butler County.

Butler County Probate Court Records

The Butler County Probate Court sits on the 8th floor at 315 High Street in Hamilton, OH 45011. Call 513-887-3300 for help. This office is the main stop for genealogy work in the county. They keep birth and death records from 1867 through 1908, marriage records going back to 1803, and probate files from 1803. Those early marriage books are some of the oldest in the state. You can get certified copies of marriage licenses and probate records right at the court.

The court also runs an online records search tool. That lets you look up case files from home before you make a trip. Probate files here include wills, estate inventories, guardianship papers, and adoption records. Keep in mind that adoption files have limits on who can see them under Ohio Revised Code Section 3705.126. But most other probate and vital records are open to the public.

For birth and death records after December 20, 1908, you need to go through the Ohio Department of Health instead. The state took over vital record keeping at that point, so the Probate Court only has the older files. Death records from 1908 to 1953 sit with the Ohio History Connection archives in Columbus.

Land Records in Butler County

The Butler County Recorder's Office is at 130 High Street, Hamilton, OH 45011. Phone is 513-887-3192. They hold land records from 1803 to the present. This means deeds, mortgages, plat maps, and surveys. If your ancestor owned land in Butler County, this is where those records live.

The Recorder's Office has online access to land records through the Butler County Records Search system. You can pull up property transfers, plats, and other filed documents without going in person. They also keep military discharge records for veterans, which can be useful if you are looking for Civil War or World War service details. Certified copies of any recorded document are available for a fee. Under Title 37 of the Ohio Revised Code, most land and vital records are public, so you should not run into access problems with deeds and mortgages.

Butler County Court and Divorce Files

The Butler County Clerk of Courts handles divorce records and civil court files going back to 1803. That is over 220 years of case records. Divorce decrees, civil lawsuits, and criminal case files are all in their system. Ohio is a public records state, which means most court files are open to anyone who asks.

If you need a certified copy of a divorce decree or civil case document, contact the Clerk of Courts at the Butler County Courthouse. Some older records may be stored off-site, so call ahead if you need files from the 1800s. The FamilySearch Wiki for Butler County has a good overview of what each office holds and can help you figure out where to start.
