Buying a used car from a private owner comes down to a short sequence: confirm the seller owns the car, collect a signed title, a bill of sale, and an odometer disclosure, pay in a way that protects both sides, insure the vehicle, and file with your state’s motor vehicle agency before its deadline runs out. The forms and fees vary by state, but the core steps are the same everywhere.
Documents You Need From the Seller
The Signed Certificate of Title
The title is the one document you cannot do without. It proves who owns the car, and the seller has to sign it over to you before you can register it in your name. Check two things before anything else: the name on the title must match the seller’s photo ID, and the Vehicle Identification Number on the title must match the car. Only the person named on the title, or someone acting under a valid power of attorney, can legally sell the vehicle. A name mismatch is a reason to walk away.
If the seller can’t find the original title, they have to request a duplicate from their state’s motor vehicle department first. That generally takes two to four weeks, so the sale cannot close until the duplicate arrives.
A Bill of Sale
A bill of sale records the buyer, the seller, the vehicle, the price, and the date. Some states hand out a standardized form; others accept any written document that covers those details. Even where it isn’t legally required, write one. Your motor vehicle agency uses the stated price to calculate sales or use tax, and the document is your evidence of what was agreed if anything goes sideways later.
The Odometer Disclosure
Federal law requires the seller to disclose the vehicle’s mileage in writing at the time of sale. The disclosure is usually printed right on the title: the seller fills in the current reading and certifies whether it’s accurate. Falsifying it carries a civil penalty of up to $10,000 per violation and criminal exposure of up to three years in prison for intentional fraud.1Office of the Law Revision Counsel. 49 USC 32709 – Penalties and Enforcement
Older vehicles are exempt. Cars with a model year of 2010 or earlier don’t require the disclosure, and 2011-and-newer vehicles become exempt once they reach 20 years past their model year.2eCFR. 49 CFR Part 580 – Odometer Disclosure Requirements If the car isn’t exempt and the seller refuses to complete the disclosure, don’t close the deal.
Notarization Where Required
About eight states require the title or bill of sale to be signed in front of a notary public before the transfer is valid. If your state is one of them, an unnotarized title gets rejected at the counter. Check your state’s motor vehicle agency website before you meet the seller and plan to sign at a bank or notary if needed.
Checks to Run Before You Pay
Match the VIN in Three Places
Every vehicle has a 17-character VIN stamped on the dashboard (visible through the windshield on the driver’s side) and on a label inside the driver’s door jamb. Both have to match the VIN on the title, character for character. A single digit off is a reason to stop and investigate.
Pull a Title History Report
The National Motor Vehicle Title Information System is a federal database of title records, odometer readings, and title brands like salvage, flood, or rebuilt. Several approved providers sell NMVTIS-based reports for a small fee, and they routinely surface problems that aren’t visible from the driver’s seat.3American Association of Motor Vehicle Administrators (AAMVA).

Pay a Mechanic to Inspect It
A title report tells you about paperwork, not mechanical condition. An independent pre-purchase inspection, usually $100 to $200, covers the engine, transmission, brakes, suspension, and frame. Private sales are almost always as-is, so what the mechanic finds beforehand is your only leverage to negotiate or walk away. Once the title is signed, the car’s problems are yours.
Paying for the Car
The common payment methods are cashier’s checks, cash, and wire transfers. A cashier’s check is usually the cleanest option: the bank guarantees the funds, the seller knows it won’t bounce, and both sides have a paper trail. Cash works for cheaper cars but gets awkward and risky in larger amounts. Wires move fast but take coordination and can cost a fee. Personal checks are a bad deal for sellers because they can bounce days after the car is gone.
Hand over the money and take the signed title in the same moment. Never pay in full before the title is signed over. Meeting at a bank branch, or at a police station’s safe-exchange zone, takes most of the risk out of the handoff.
If the Car Still Has a Loan on It
When the seller still owes money, the lender holds a lien on the title and the title cannot transfer to you until the loan is paid off. Call the lender for the exact payoff amount, then arrange for your money to go directly to the lender rather than to the seller. When the lender gets the payoff, it releases the lien and either mails a clean title or authorizes an electronic release, depending on the state. The seller keeps anything above the payoff.
The cleanest way to do this is to meet at a branch of the seller’s lender and complete the payoff and title release in a single visit. If the lender has no local branch, or the state uses electronic titles, an escrow service can hold your money until the title is released. Do not pay the seller directly and trust them to clear the loan on their own. If they don’t, the lender can repossess the car from you.
Insure the Car Before You Drive It
You need auto insurance before you drive the car off, and almost every state requires proof of insurance when you apply for registration. If you already have a policy, call your insurer to add the new vehicle; coverage can usually start the same day. If you don’t, bind a policy before you finalize the purchase. Driving uninsured, even for the trip home, can mean fines, license suspension, and personal liability for any accident along the way.
Filing With Your State’s Motor Vehicle Agency
Bring the signed title, the bill of sale, and proof of insurance to your state’s motor vehicle agency to apply for a new title and registration in your name. Expect to pay three things:
- Sales or use tax, calculated from the purchase price. Rates run from zero in Alaska, Delaware, Montana, New Hampshire, and Oregon up to roughly 8 percent in other states, with county add-ons in some places.
- A title fee, usually $15 to $85, to issue the new certificate.
- A registration fee, which varies widely by state and may be based on weight, value, or age. It can be under $30 or several hundred dollars.
Watch the Transfer Deadline
Every state sets a window to complete the transfer after the sale, commonly 10 to 30 days, with some as tight as 5 and some as generous as 60. Miss it and you’ll pay a late penalty. Some states charge a flat fee that climbs the longer you wait; others add a percentage penalty on the unpaid sales tax. A handful treat a missed transfer as a misdemeanor. Find your state’s deadline the day you buy the car and don’t wait until the last day to file.
Temporary Permits
If you need to drive before registration is processed, most states sell temporary transit permits or temporary plates valid for 20 to 30 days, usually for about $10 to $25.
Inspections and Emissions
Roughly half the states require a safety inspection, an emissions test, or both before you can register a used vehicle. Some apply the rule statewide; others only in certain metro areas. Ask the agency what applies to your address so the requirement doesn’t hold up your registration.
Make Sure the Seller Does Their Part
The seller has filings of their own. Most states require them to submit a release of liability or notice of transfer, which formally separates them from the car so they aren’t billed for your parking tickets, tolls, or accidents. Deadlines range from about 5 to 30 days. In most states, the seller keeps the license plates rather than leaving them on the car. Confirm the seller plans to file the release and remove their plates. If they don’t, the paper trail stays muddled, and that can come back on you when you try to register.
