Most private car sales run on trust and a handshake right up to the moment they do not: the buyer who promised to come back with the money, the seller who kept the deposit and sold to someone else, the transmission that failed two days after the cash changed hands. A vehicle purchase agreement is the contract that governs the deal between the handshake and the title transfer: price, deposit, closing date, condition, and who bears which risk, all signed before anyone is committed.
This form covers the terms private sales actually fight about: the deposit and its refund rule, the closing date, the odometer certification, lien payoff, and as-is terms, and pairs at closing with a bill of sale and the title signover.
Purchase agreement vs. bill of sale: two documents, two moments
The two documents are constantly confused because casual sales skip the first one. The purchase agreement is the contract: signed when the parties agree on the deal, it binds both sides to close on the stated terms, and it is what makes a deposit meaningful. The bill of sale is the receipt: signed at closing, it records that the transfer happened, and the DMV asks for it when the buyer registers. A same-day cash sale can survive on a bill of sale alone; any deal with a gap between agreement and closing (a deposit, financing, a pending lien payoff, an out-of-state buyer) needs the purchase agreement, because that gap is exactly where deals collapse.
| Purchase agreement | Bill of sale | |
|---|---|---|
| When it is signed | When the deal is struck | At closing |
| What it does | Binds both parties to close | Records the completed transfer |
| Deposit terms | Yes, with the refund rule | No |
| DMV registration | Not usually requested | Requested in many states |
Deposits, closing, and lien payoffs: where private sales go wrong
Deposit disputes are the most common private-sale conflict, and they are entirely preventable: write the refund rule down. This form offers the three standard options: refundable only if the seller cannot deliver (the fair default, compensating the seller for holding the car off the market), fully refundable, and non-refundable. The second failure point is the financed car: a lender's lien on the title blocks transfer until the loan is paid, so the safe pattern is closing at the lender's branch or with a written payoff, with the agreement stating that ownership passes only when the lien release and title are delivered. The third is payment itself: cleared funds only, meaning cash counted in person, a cashier's check verified with the issuing bank, or an electronic transfer confirmed received, never a personal check or an overpayment-and-refund arrangement, which is a classic scam pattern.
Verify the cashier's check before handing over the title
Counterfeit cashier's checks are the dominant private-sale scam. Call the issuing bank using a number you looked up yourself (not one printed on the check), or close the sale inside the buyer's bank and watch the check being issued.
As-is sales, disclosure, and the odometer
Between private parties, used vehicles sell as-is in most states: no implied warranties, the buyer inspects, and post-sale breakdowns are the buyer's problem. This form defaults to as-is and lets the seller add specific written promises when there are real ones to make (a documented timing belt, a clean accident history). As-is has one hard limit everywhere: fraud. A seller who actively conceals a known defect, rolls back an odometer, or lies about accident history remains liable despite the as-is clause, which is why the optional known-defects disclosure protects the seller as much as the buyer. The odometer statement is federal law, not a formality: mileage must be disclosed on the title at transfer for most vehicles under 20 model years old, and knowingly false disclosure carries federal civil and criminal penalties.
Title, tax, and notice-of-sale rules vary by state
Some states require notarized title signatures, most set a deadline for the buyer to retitle and pay sales tax, and many require the seller to file a notice of sale or surrender the plates to end their liability. Check both states' motor vehicle agencies when buyer and seller live in different states. This template is a self-help document, not legal advice.
Frequently asked questions
Do I need a purchase agreement and a bill of sale?
For any sale that does not close on the spot, yes: the purchase agreement binds both parties between the handshake and the closing, and the bill of sale records the completed transfer for the DMV. For a same-day cash sale, many parties sign only a bill of sale, accepting the risk that nothing binds either side until the moment money and title change hands.
Is a deposit on a car refundable?
Whatever the signed agreement says, which is why the rule must be written down. The common default is that the deposit is refundable only if the seller fails to deliver as promised, and kept by the seller if the buyer walks away, compensating the seller for holding the car off the market. Unwritten deposits produce the most disputes in private sales.
Can I sell a car that still has a loan on it?
Yes, but the lender's lien must be paid off and released before the title can transfer. The safe structure, which this form supports, is closing at or with the lender: the buyer's funds pay the loan directly, and the seller delivers the lien release and title as soon as the lender issues them. Never pay in full against a promise to clear the lien later.
What does selling a car as-is mean?
No warranties survive the sale: the buyer takes the vehicle with all faults, known and unknown, and post-sale repairs are the buyer's responsibility. As-is does not protect fraud: concealing a known defect, tampering with the odometer, or lying about accident history keeps the seller liable in every state. Disclose honestly and let the paper do its work.
Is the odometer disclosure really required?
Yes, by federal law, for most vehicles less than 20 model years old: mileage is disclosed on the certificate of title (or the state's disclosure form) when the vehicle transfers. A knowingly false statement is federal odometer fraud, carrying civil liability and criminal exposure. This agreement records the certified reading; the formal disclosure is completed at closing.
