What to do after buying a used car comes down to a short list on a tight clock: insure it, confirm the title is clean, bring your paperwork to your state’s motor vehicle office, and pay the taxes and fees before your state’s deadline runs out. Most states give you between 10 and 30 days from the sale date to transfer the title and register the car in your name. There is no federal cooling-off period for vehicle purchases, so once you’ve signed, the car is yours and the clock is running.1Federal Trade Commission.

Get Insurance Before You Drive Off
Every state except New Hampshire requires liability insurance before you operate a vehicle on public roads. Minimum coverage floors generally sit between $15,000 and $50,000 for bodily injury per person, with a separate amount for property damage. Call your insurer with the VIN and odometer reading before you leave the seller’s property.
If you already carry a policy on another vehicle, your insurer may extend automatic coverage to the new car for a short grace period, often seven to thirty days. That’s a convenience, not a reason to put off the call. Add the vehicle formally the same day. Driving without proof of insurance can mean fines, license suspension, and registration holds that will complicate every step that follows.
Check the Title for Liens and Brands
Before you spend a morning at the motor vehicle office, confirm the title has no liens, no brands, and no gaps in the ownership chain. A lien means a lender still has a financial claim on the car. If the seller never paid off their auto loan, the lender holds the title and technically still owns the vehicle. Buying a car with an outstanding lien can leave you responsible for someone else’s debt or, worse, lead to repossession out of your driveway.
The National Motor Vehicle Title Information System (NMVTIS) is a federal database run by the Department of Justice that tracks title records, odometer readings, total-loss history from insurance carriers, and salvage or junk designations. You can run a report through one of the approved providers listed at VehicleHistory.gov. It won’t catch every problem, but it does flag brands like “salvage” or “flood,” prior total-loss declarations, and discrepancies in ownership.2U.S. Department of Justice. Research Vehicle History
If the seller still owes money on the car, the safest move is to close the transaction at the lender’s office or through an escrow service so the loan gets paid off at the same time the money changes hands. The lender then releases the lien and either signs the title or transmits an electronic release to the state. Never accept a promise that the seller “will pay it off later.” Once your money is gone, you have no leverage.
Documents to Bring to the Motor Vehicle Office
Your state’s DMV website will list the exact paperwork, and a missing document means a wasted trip. Check it before you go. In most states you will need:
- The certificate of title, signed over by the seller in the assignment section on the back, and signed by you as the buyer. Both of you print your names and record the sale date. Signatures should match your government-issued IDs.
- A bill of sale listing both parties’ full names and addresses, the VIN, year, make, model, odometer reading, sale price, and date. Most state motor vehicle websites post a free template.
- An odometer disclosure. Federal law requires the seller to provide a written mileage statement at the time of transfer, and many states fold this into the title itself. If a seller rolls back the odometer or lies on the statement, you can sue for three times your actual damages or $10,000, whichever is greater.3Office of the Law Revision Counsel. 49 USC 32705 – Disclosure Requirements on Transfer of Motor Vehicles4GovInfo. 49 USC 32710 – Civil Action by Private Person
- Proof of insurance, either an insurance card or a binder letter from your carrier showing the new vehicle is covered.
- A valid photo ID. Some states will also want to see the seller’s ID.
If the Seller Can’t Find the Title
This happens more often than you’d expect. If the seller doesn’t have the original title in hand, they need to apply for a duplicate from their state’s motor vehicle office before the sale can go through. Most states issue duplicates the same day or within a few business days for a small fee. Don’t accept a handshake that the title will “show up.” Without a properly assigned title, you cannot register the car in your name.
Notarization
Some states require the seller’s title signature to be notarized. Others don’t. If yours does, handle it at the sale while the seller is still in front of you. Chasing a seller down weeks later for a notarized signature is one of those headaches that turns a routine transfer into a project. Your state’s motor vehicle website will say whether notarization applies.
File the Transfer Within Your State’s Deadline
Bring everything to your state’s motor vehicle office. Many states now offer online portals or mail-in options that handle at least part of the process, though first-time title transfers often still require an in-person visit. The agent verifies your paperwork, collects your fees, and processes the title into your name. Most offices issue a temporary registration or paper tag on the spot so you can drive legally while the permanent title and plates are produced. The hard-copy title usually arrives by mail within three to six weeks.
Deadlines range from 10 to 30 days depending on the state. Late fees stack up fast, and some states suspend your ability to register the vehicle at all until the penalties are paid. If your local office has long wait times, book an appointment or use the mail-in option well ahead of the deadline. The last day is not the day to try.
Plates are handled differently from state to state. In some, plates belong to the vehicle and transfer with it. In others, plates belong to the person; the seller keeps them and you get new ones. A few states let you move plates from a car you already own to the one you just bought. The counter agent will tell you which rule applies.
If you bought from a dealership rather than a private seller, the dealer typically handles most of the title and registration paperwork and collects the sales tax at the point of sale. You’ll usually leave with temporary tags and receive your permanent title and plates by mail. Still worth following up if nothing has arrived within six weeks. Paperwork gets lost.
Sales Tax and Fees to Expect
Used car purchases are subject to sales or use tax in most states. Five states charge none at all; the rest range up to about 8.25%. Tax is calculated on the purchase price, but some states will substitute their own fair-market-value estimate if the number you reported looks suspiciously low. A $500 sale price on a car that books for $8,000 will draw questions.
On top of the tax, expect a title transfer fee and a registration fee. Title fees generally fall between $15 and $100, and registration runs another $50 to $200 depending on the vehicle’s weight, age, or type. Some states tack on documentation or technology fees. Total it up before you go. Most offices take checks and cards, but a few still require exact payment by check or money order for certain transactions.
Inspections After a Change of Ownership
A transfer of ownership triggers mandatory inspections in many states. Requirements vary widely. Some states require both emissions and safety inspections, some require one, some require neither.
Emissions testing checks that the vehicle’s exhaust and onboard diagnostic systems meet air-quality standards. Safety inspections cover brakes, tires, lights, steering, and structural integrity. Both must be done at authorized inspection stations. If the car fails, you typically have around 30 days to make repairs and retest before your registration is affected.
If you bought the car in another state, or you’re registering a vehicle previously titled elsewhere, your new state may require a physical VIN inspection before issuing a new title. A law enforcement officer or DMV agent compares the VIN plate on the car to the documents to confirm it’s the same vehicle. This is an anti-theft measure. Check whether your state requires it so you can schedule the inspection in advance.
Red Flag: Title Jumping
Title jumping is when someone buys a car and resells it without ever registering it in their own name. The seller signs the previous owner’s title directly over to you, skipping themselves entirely. It’s illegal in every state because it evades sales tax, breaks the ownership chain, and cuts off your consumer protections.
If you’re buying from a private seller and the name on the title doesn’t match the person in front of you, that’s a warning. The seller may be a curbstoner, someone who flips cars without a dealer license. Walk away. A broken chain of title can make it impossible to register the car, and even if you only discover the problem after you’ve paid, the state may refuse to process your registration until the gap is resolved. That can take months and cost extra fees.
If You Have Buyer’s Remorse
Federal law gives you no right to return a car after you buy it. The FTC’s three-day cooling-off rule, which allows cancellation of certain purchases made at temporary locations, specifically excludes motor vehicles.1Federal Trade Commission. Buyers Remorse – The FTCs Cooling-Off Rule May Help A handful of states have narrow return or cancellation provisions, but most do not. Once you sign, you own it.
If you bought from a dealer, federal rules required them to post a Buyers Guide in the vehicle’s window before the sale. That form shows whether the car was sold “as is” with no dealer warranty, with implied warranties only, or with a specific dealer warranty covering named systems for a set period. Keep your copy. If the dealer checked a warranty box and then refuses to honor it, that’s a breach you can enforce.5eCFR. 16 CFR Part 455 – Used Motor Vehicle Trade Regulation Rule Private sellers generally aren’t bound by implied warranty rules, because those protections apply only to merchants who regularly deal in the goods being sold.6Federal Trade Commission.
