Car Payment Agreement Template (US)
Updated on July 30, 2026
A car payment agreement records a seller-financed vehicle sale: the buyer pays the price in instalments instead of all at once, and the seller keeps a security interest in the vehicle — the right to repossess it — until it's paid off. Getting the security interest actually perfected, not just written down, is the part most free templates skip entirely.
The agreement below is the form: type straight into the highlighted blanks, add the interest clause where it sits if the balance carries a rate, and both parties sign on the signature lines. Download a clean Word or PDF file with no sign-up and no watermark.

Do consumer-credit rules apply to a private seller?
The federal Truth in Lending Act and its implementing Regulation Z apply to a "creditor" — defined as someone who regularly extends consumer credit. A private individual selling their own car once, on instalments, generally doesn't meet that bar and isn't required to give the Regulation Z disclosures a dealer or finance company would have to provide. That doesn't mean anything goes, though: some states separately regulate retail instalment sales, and a seller who does this repeatedly (effectively acting as a dealer) can end up covered by rules a genuine one-off private sale wouldn't trigger.
A written clause isn't enough — the lien has to be perfected
Writing "the seller retains a security interest until paid in full" into the contract protects you against the buyer, but not automatically against everyone else. Under the Uniform Commercial Code, a security interest in a vehicle is perfected by getting it noted as a lien on the vehicle's certificate of title through the state's motor vehicle agency — not by filing a UCC financing statement, which is how security interests in most other kinds of property get perfected. If the lien isn't noted on the title, a buyer could sell the car to someone else who takes it free of your claim, or a bankruptcy trustee could treat your interest as unperfected.
This is exactly what most car payment templates get wrong: they include the security-interest language but never mention that it has to actually be filed with the state title agency to mean anything against third parties.
Working out the payment schedule
If you're financing a meaningful balance over several months or years, it's worth working out the actual amortisation — how much of each payment is principal versus interest, and the running balance — rather than just dividing the total by the number of payments. Our free amortization calculator will build that schedule for you once you know the balance, rate and term.
The clauses, explained
- Parties and vehicle
- Identifies the seller and buyer and the vehicle by year, make, model and VIN.
- Purchase price and payment schedule
- The total price, any down payment, and the instalment amount, frequency and number of payments.
- Interest (optional)
- Add this clause if the seller is charging interest on the outstanding balance rather than simply spreading the price over time interest-free.
- Retention of title / security interest
- States that the seller keeps a security interest in the vehicle until it's paid in full, and — critically — that the seller will apply to have that interest noted as a lien on the certificate of title with the state motor vehicle agency, which is what actually perfects it.
- Default and late payments
- What happens if a payment is missed — a grace period, a late fee, and the seller's right to repossess after a specified default period.
- Insurance and risk of loss
- The buyer takes possession and risk of loss even though the seller retains a security interest, so the buyer should carry insurance from the date of possession.
- Odometer disclosure
- Federal law requires an odometer disclosure at the time ownership transfers for most vehicles. Confirm the current exemption rules for older vehicles before relying on this being unnecessary.
Requirements checklist
Truth in Lending Act — private-seller exception
Regulation Z applies to creditors who regularly extend consumer credit. A one-off private seller financing a single sale generally isn't a "creditor" under the Act and isn't required to give Reg Z disclosures — but a seller who does this repeatedly may be treated differently.
eCFR — 12 CFR Part 226 (Regulation Z)Perfecting the security interest
A security interest in a vehicle is perfected by having it noted as a lien on the certificate of title through the state motor vehicle agency, not by filing a UCC-1 financing statement. An unnoted ("clean") title means the interest isn't perfected against third parties.
UCC §9-311
How to use this template
- Fill in the parties and vehicle. Type the seller's and buyer's details and the vehicle's year, make, model and VIN into the highlighted blanks.
- Set the price and payment schedule. Fill in the total price, down payment, instalment amount and number of payments. Use our amortization calculator first if you want to work out interest and principal per payment.
- Decide whether to charge interest. The interest clause sits in the document with its own Add control — add it if the balance carries a rate rather than being spread interest-free, and the clauses after it renumber themselves.
- Sign, download and file the lien. Sign on the signature line, download the agreement as a Word or PDF file, and apply to your state's motor vehicle agency to have your security interest noted on the title — this is the step that actually protects you.
Frequently asked questions
Do I need to follow Truth in Lending Act rules to sell my car on payments?
Generally not, if you're a private individual selling your own vehicle as a one-off transaction — Regulation Z applies to creditors who regularly extend consumer credit, which a single private sale typically doesn't meet. Selling multiple vehicles on credit repeatedly could change that analysis.
Is writing a security-interest clause in the contract enough to protect me?
No. The contract clause matters, but to be protected against other creditors or a subsequent buyer, the security interest needs to be perfected by having it noted as a lien on the vehicle's certificate of title with your state's motor vehicle agency — not just written into the agreement.
What happens if the buyer stops paying?
If your security interest is properly noted on the title, you can generally repossess the vehicle after a default under your state's rules once the agreed default and cure period has passed. If it isn't perfected, recovering the vehicle is much harder, especially if it's been sold on.
Who's responsible for insurance while the seller still holds a security interest?
The buyer, in almost every case — they have possession and risk of loss from the date of the sale, even though the seller retains an interest until the balance is paid. The agreement should make clear the buyer must insure the vehicle from day one.
Do I still need to give an odometer disclosure if the sale is on instalments?
Federal law requires an odometer disclosure at the time ownership transfers for most vehicles, regardless of how the price is paid. Some very old vehicles are exempt — check the current federal exemption rules before assuming yours doesn't need one.
