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.

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.
