Ohio — quick answer
In Ohio, a bill of sale is situational for a private vehicle sale and notarization is required. No witnesses are required. The relevant state form is BMV 3770. Ownership is transferred through the Ohio BMV via the assigned title.
Is a bill of sale required in Ohio?
Situational. For casual private sales the seller assignment (or BMV 3770 when the title space is full) must be notarized.
Seller signs the title assignment before a notary; the buyer titles at a County Clerk of Courts Title Office.
Does a Ohio bill of sale need to be notarized?
Required. Ohio is a title-notary state: for private sales the seller's signature on the title assignment must be notarized. Dealers are exempt.
Because Ohio requires notarization, do not sign the title or bill of sale until you are in front of a notary. Both the document and a valid ID should be ready, and many banks and shipping stores offer notary services.
Witness requirements
No. Ohio does not require witnesses for a standard private bill of sale.
Odometer disclosure
Federal law requires a written odometer disclosure when title is transferred for vehicles less than 20 years old. As of 2026 that means model year 2011 and newer; model year 2010 and older are generally exempt. Record the exact mileage — never round it. See the NHTSA rule.

Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
