Ohio Probate Records
Probate is the “court procedure by which a will is proved to be valid or invalid” and encompasses “all matters and proceedings pertaining to the administration of estates, guardianships, etc.” Various types of records are created throughout the probate process. These may include, wills, bonds, petitions, accounts, inventories, administrations, orders, decrees, and distributions. These documents are extremely valuable to genealogists and should not be neglected. In many instances, they are the only known source of relevant information such as the decedent’s date of death, names of his or her spouse, children, parents, siblings, in-laws, neighbors, associates, relatives, and their places of residence. They may also include information about adoption or guardianship of minor children and dependents. For further information about the probate process, types of probate records, analyzing probate records, and to access a glossary of probate terms, see United States Probate Records.
Probate records were kept in all counties from the time of each county's creation. Until the establishment of separate probate courts in 1852, these records were kept in the courts of common pleas. You can obtain copies of these records by writing to the clerk of the appropriate county. For more information see the Ohio County Probate Records page.
Probate records are listed in the Locality Search of the Family History Library Catalog under OHIO, [COUNTY] - PROBATE RECORDS.
Most Ohio probate records are well indexed and are on microfilm or in published format at the Family History Library. The files date from the creation of each county to at least 1900 and sometimes to the 1970s.
