To sell your car privately, the documents needed to sell a car privately start with the signed certificate of title and, in most cases, include a bill of sale, a federal odometer disclosure, a lien release if a lender was ever on the title, any inspection or emissions certificate your state requires, and a release of liability filed with your motor vehicle agency after the handover. A few of these are federal, most are state-specific, and one or two depend on your own circumstances.
The Certificate of Title
The title is the legal proof that you own the car. No title, no sale. You need the physical document in hand before you list the vehicle. If the original is lost or damaged, apply for a duplicate through your state’s motor vehicle agency. Fees vary widely and processing can take anywhere from a same-day counter visit to several weeks by mail, so don’t wait until a buyer is lined up.
When you’re ready to transfer, fill out the assignment section on the back. You’ll need the buyer’s full legal name and address, the odometer reading at the time of sale (drop any tenths of a mile), the sale price, and the date. Sign and print your name exactly as it appears on the front of the title. Errors, cross-outs, and correction fluid can invalidate the document in many states, which means applying for a duplicate before the sale can close.
If two people are listed as owners, how the names are joined matters. Names connected by “and” typically require both owners to sign. Names connected by “or” usually let either owner sign alone. When a co-owner can’t be present, some states accept a limited power of attorney authorizing one owner to sign for the other. Check with your state’s motor vehicle agency for the correct form and any notarization requirements before the day of sale.
Bill of Sale
A bill of sale is your receipt for the transaction. Not every state requires one, but skipping it is a mistake even where it’s optional. The document creates a written record of who sold what to whom, for how much, and when, and that paper trail protects you if the buyer later disputes the terms or a question about ownership surfaces.
You can draft one yourself. Include the full legal names and current addresses of both seller and buyer; the vehicle’s year, make, model, color, and VIN; the exact sale price; the odometer reading at the time of sale; the date of the transaction; and an as-is statement confirming you are selling the vehicle with no warranties and the buyer accepts it in its current condition.
The as-is clause matters more than most sellers realize. Without it, a buyer who discovers mechanical problems after the sale could try to argue you made an implied guarantee. Both parties should sign and date the document, and each person should keep a copy.
Odometer Disclosure Statement
Federal law requires the seller to provide a written odometer disclosure on most private vehicle transfers. The disclosure records the mileage at the time of sale and confirms whether that reading is accurate, so the buyer knows the car hasn’t been rolled back. In many states, the disclosure is built into the title’s assignment section, so you complete it when you sign the title over. Some states use a separate form.
The regulation spells out what the disclosure must include: the odometer reading without tenths of a mile, the date of transfer, the printed names and addresses of both seller and buyer, and the vehicle’s make, model, year, body type, and VIN.1eCFR. 49 CFR 580.5 – Disclosure of Odometer Information If you know the odometer is broken or doesn’t reflect the true mileage, you must state that the actual mileage is unknown rather than reporting the number on the dash.
Not every vehicle requires this disclosure. The exemption rules split at model year 2010. Vehicles built in 2010 or earlier fall under a 10-year exemption window, and by 2026 every one of those vehicles is already exempt. Vehicles from model year 2011 onward carry a longer 20-year disclosure window, meaning the earliest any of those become exempt is 2031.2eCFR. 49 CFR 580.17 – Exemptions In practical terms for 2026: if your car is a 2011 or newer model, you need the disclosure. If it’s 2010 or older, you don’t.
Lien Release
If you financed the vehicle and the loan is paid off, the lender’s name may still appear on the title as a lienholder. You need a lien release to prove the debt is satisfied before you can cleanly transfer ownership. This document typically comes from the lender on company letterhead or on a state-specific release form, and it includes the vehicle description, your name as the owner, and a statement that the lien is released. Some states require the release to be notarized.
If you paid the loan off recently, contact your lender to confirm the release has been processed and request a copy if you haven’t received one. Some lenders automatically send a clean title with no lienholder listed; others send the release separately and expect you to take it to your motor vehicle agency to get an updated title. Sort this out before you have a buyer waiting.
If You Still Owe on the Loan
You can sell a car with an active loan, but the lender holds a legal interest in the vehicle and controls the title. Call your lender first and ask for the payoff amount, which is the exact balance needed to clear the loan including any accrued interest. That number is often slightly higher than your last statement balance. If the car is worth more than you owe, the buyer’s payment goes to the lender first, the lender releases the title once the loan is satisfied, and you receive whatever is left. If you owe more than the car is worth, you’ll need to cover the difference out of pocket before the lender will release the title. Lenders with local branches often let you bring the buyer in to handle payoff, release, and signing in one visit; online lenders usually require full payment before mailing the title. Ask your lender how they handle private-party sales before you list.
Inspection or Emissions Certificate
Some states require the seller to provide a current safety inspection certificate, emissions test result, or smog check before the vehicle can be transferred or re-registered. Requirements vary significantly. Some states mandate annual inspections, others require them only at the time of sale, and some have no inspection requirement at all. A handful of states limit emissions testing to specific counties with air quality concerns.
If your state requires an inspection, get it done before you advertise the car. A passed inspection reassures buyers and avoids last-minute delays. If the vehicle fails, you’ll either need to make repairs or disclose the failure to the buyer, who may then handle the inspection themselves depending on your state’s rules. Your state’s motor vehicle agency website spells out what applies in your area.
Release of Liability
After handing over the title and keys, file a release of liability (sometimes called a notice of transfer) with your state’s motor vehicle agency. This form notifies the state that you no longer own the vehicle and protects you from liability for anything the new owner does with it. Without it, parking tickets, toll violations, and even accident claims can land on your doorstep.
Most states require you to file within a set window after the sale, often five to ten business days. The form typically asks for the VIN, the buyer’s name and address, the date of sale, and the odometer reading. Many states let you file online and give you an instant confirmation receipt, which is worth printing and keeping with your copy of the bill of sale. Don’t skip this step just because the buyer promises to register the car right away. People procrastinate, and you’ll be the one fielding the consequences.
Remove your license plates before the buyer drives away. Some states require you to surrender the plates to the motor vehicle agency; others let you transfer them to your next vehicle. Either way, the plates stay with you, not the car.
Keep Insurance Active Until the Sale Is Done
Keep your auto insurance in force until the sale is fully complete: title signed, payment verified, keys handed over. If the buyer gets into an accident test-driving the car or driving it home before the title transfer is finalized, your policy is what responds. Canceling too early can also trigger fines or a license suspension in states that require continuous insurance coverage for registered vehicles.
Once the sale is done and you’ve filed the release of liability, call your insurer to cancel coverage on the vehicle. Have your copy of the bill of sale handy, since the insurer will want proof of the sale date. If you’re replacing the car with another vehicle, your insurer can usually transfer the policy rather than cancel and restart, which avoids a coverage gap.
If You Sold the Car for a Profit
Most people sell a personal car for less than they paid for it, and in that case there’s nothing to report. The IRS does not let you deduct a loss on the sale of personal-use property. If you sell for more than your original purchase price, which can happen with classic cars, collector vehicles, or models that appreciated due to scarcity, the profit is a capital gain you’re required to report on Form 8949 and Schedule D of your federal tax return.3Internal Revenue Service. Publication 544 – Sales and Other Dispositions of Assets Keep the original purchase receipt and the bill of sale from your private sale to document your cost basis and selling price.
