In a private car sale, the title is the transaction — the signed-over certificate is what actually moves ownership, and everything else (the bill of sale, the odometer disclosure, the DMV filing) exists to back it up. The mechanics are state-specific because titles are DMV documents, but the moving parts are the same everywhere, and so are the ways deals go wrong.
The seller completes and signs the assignment section on the title itself — names exactly as printed, no cross-outs, since corrections can void a title and force a duplicate. A handful of states require the signatures to be notarized, which is worth confirming before meeting the buyer rather than after.
Federal law (49 U.S.C. § 32705) requires a written odometer disclosure when ownership transfers, usually on the title itself — and since a 2021 rule change, vehicles from model year 2011 onward need the disclosure for 20 years instead of the old 10. Knowingly writing a false mileage is a federal offense with civil and criminal penalties.
A title listing a lienholder can't cleanly transfer — the buyer needs the lien release (a signed release document or the lender's notation) proving the loan is paid. Buying a car with an unreleased lien means buying the seller's unpaid loan problem, because the lender's interest follows the car.
Price, date, VIN, mileage, both parties' names and signatures, and 'sold as-is' where that's the deal. Some states require one for registration or tax purposes; everywhere, it's the document that settles later arguments about what was agreed and protects the seller on liability questions after the handoff.
The buyer applies for a new title and registration within the state's deadline — often 10 to 30 days — paying sales tax and title fees, with late-transfer penalties after that. The seller's counterpart, offered in many states, is filing a notice of transfer or release of liability, which cuts off responsibility for the new owner's tickets, tolls, and accidents.
It usually starts with paying before the title is in hand. The escalation path: a written demand to the seller, then the state DMV's cures — a duplicate title request if the seller cooperates, a bonded title (backed by a surety bond) in the many states that offer one, or a court-ordered title where they don't. Small claims court can also unwind the sale or recover the bond cost from a seller who won't perform.
