Seller signs the title assignment before a notary; the buyer titles at a County Clerk of Courts Title Office.
Does a Ohio vehicle bill of sale need to be notarized?

Do I need a bill of sale to register a car?
It depends on your state. Many states accept the signed-over title alone, while others require a bill of sale to confirm the purchase price for sales tax. Our state pages tell you exactly what your DMV expects.
Does a vehicle bill of sale need to be notarized?
In most states, no. A handful of states require the title assignment to be notarized for a private sale: Louisiana, Ohio, Pennsylvania, North Carolina, and Kentucky. A few others require notarization only in specific tax situations.
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.
