After buying a used car from a private seller, you have two jobs: transfer the title into your name and register the vehicle with your state’s motor vehicle agency. Most states give you between 10 and 30 days from the sale date to finish both. Miss the window and you’ll pay late fees; drive without completing it and you’re on the road with a vehicle that still legally belongs, on paper, to someone else.
Here is what to do after buying a used car, in the order it actually needs to happen.
Insure the Car Before You Drive It
You cannot register a vehicle without active insurance on it, and you shouldn’t drive it off the seller’s property without coverage either. Call your insurance company before you hand over payment. Most insurers can add the vehicle to an existing policy the same day or issue a temporary binder so you’re covered from the moment the sale closes. Have the VIN ready — your agent will need it.
Gather the Paperwork You’ll Need
Before you leave the seller, make sure you walk away with everything the motor vehicle agency will ask for. If a document is missing, it’s much easier to get it from the seller now than to track them down a week later.
- The certificate of title, signed over to you by the seller in the assignment section on the back. This is the single most important document in the transaction.
- A bill of sale listing the full legal names and addresses of both parties, the VIN, make, model, and year of the vehicle, the sale price, and the date. Your state’s motor vehicle agency usually posts a template on its website. Even where it isn’t legally required, it protects you and helps the state calculate the tax you owe.
- A written odometer disclosure statement, signed by both of you, recording the mileage at the time of sale. Federal law requires this disclosure for most used vehicles; older vehicles become exempt once they pass a 20-year threshold from their model year.
- Your proof of insurance and a valid photo ID, which you’ll need at the agency.
If the mileage the seller writes down doesn’t line up with the odometer reading, or either number looks inconsistent with the vehicle’s apparent wear, stop and ask questions before signing anything. Odometer fraud is a federal offense,1Office of the Law Revision Counsel. 49 USC 32709 – Penalties and Enforcement and a mismatch is one of the clearest warning signs that something is wrong with the vehicle or the paperwork.
Complete the Title Transfer Correctly
The title transfer happens on the physical certificate of title itself. The seller signs the assignment of title section on the back. You fill in your full legal name and current address in the transferee section. The odometer reading at the time of sale goes in the designated space on the title, and it must match the number on your separate odometer disclosure statement. Confirm the sale date is written correctly, because that date starts the clock on your registration deadline.
Be careful. Correction fluid, crossed-out entries, or writing in the wrong field can void the title entirely. If that happens, the seller has to apply for a duplicate title through their state’s motor vehicle agency, which costs money and takes weeks. Read every field before you write in it, use a pen with dark ink, and double-check spelling. Some states offer an affidavit of correction form that can fix minor clerical mistakes without a full duplicate.
Several states require the signatures on the title to be notarized. A notary verifies the identity of each signer to prevent fraudulent transfers. If your state requires notarization, do not sign the title until you’re in front of the notary. A pre-signed title will be rejected. Notary fees for standard signature witnessing are set by state law and typically range from a few dollars to $15 per signature.
If the Title Shows a Lien
A lien on the title means a lender still has a financial interest in the vehicle, and a title with an active lien generally cannot be transferred. The seller must either pay off the loan and give you a formal lien release, or arrange for the lender to participate directly in the sale. Many states now use electronic lien and titling systems, where the lien release is transmitted digitally and the motor vehicle agency can confirm when it’s been cleared. Don’t finalize payment until the lien question is resolved.
Get a Temporary Tag So You Can Drive It Home
Your permanent plates and registration won’t be issued the day of the sale, so you need something that lets you drive legally in the meantime. Most states offer a temporary operating permit or transit plate for exactly this situation. Depending on where you are, you might apply online, visit a motor vehicle office, or in some cases receive a temporary tag directly from the seller (more common with dealer sales than private ones).
Temporary permits are generally valid for 15 to 30 days, which gives you time to complete registration, pass any required inspections, and receive your permanent plates. If you’re trading in or replacing an existing vehicle, some states let you transfer plates from the old one, which can skip the temporary tag step entirely.
Register the Vehicle and Pay What You Owe
Registration is where you make it official. Take your signed title, bill of sale, odometer disclosure, proof of insurance, and photo ID to the state motor vehicle agency or a local tax office. Many states accept online or mail-in submissions too, so check your options before you drive down and stand in line.
You’ll pay three things at registration:
Sales or use tax. The state assesses tax on your purchase, usually based on the price recorded on the bill of sale. State-level rates range from 0% in a handful of states to over 8%, and many counties and cities add local surcharges. Some states assess tax based on fair market value instead of the stated purchase price, particularly if the reported price looks suspiciously low compared to book value. You owe tax in the state where you register the vehicle, regardless of where you bought it.
Title transfer fee. A flat charge that varies widely by state.
Registration fees. Calculated based on factors like the vehicle’s weight, age, or value. Altogether, budget a few hundred dollars beyond the sales tax for these administrative costs.
Once your application is processed, the agency issues your registration card and either new license plates or a validation sticker for existing plates. Your new certificate of title is typically mailed to you within a few weeks.
Watch the Deadline
Every state sets a deadline for registering after a purchase, commonly 10 to 30 days. Late fees grow the longer you wait. If your state also requires a safety inspection or emissions test before registration, build that into your timeline — scheduling early is the easiest way to avoid blowing the deadline.
Pass Any Required Inspections First
Roughly half of U.S. states require a safety inspection, an emissions test, or both as a condition of registration. Safety inspections typically cover brakes, steering, suspension, lights, tires, windshield condition, and seatbelts. Emissions inspections focus on the exhaust system and onboard diagnostics, and are most common in urban counties with air quality concerns.
Not every vehicle needs an emissions test. Common exemptions include electric vehicles, motorcycles, very new vehicles (often under four to six model years old), and vintage vehicles past a certain age. Your state or county motor vehicle agency will confirm whether yours needs testing. If the vehicle fails, some states issue a temporary operating permit so you can drive it to a repair shop and come back for a retest.
Extra Steps If You Bought It Out of State
An out-of-state purchase follows the same title-transfer process with the seller, but your home state will usually ask for more before issuing a new title. Common additional requirements include a VIN inspection performed by law enforcement or a designated agent in your home state, a smog or emissions test if your county requires one, and the original out-of-state title or a certified copy. Some states issue a temporary “foreign ownership” registration while they process the new title, which can take several weeks.
You still pay sales or use tax in your home state based on the purchase price, even though the transaction happened elsewhere. Call your home state’s motor vehicle agency before you travel to pick up the vehicle. Confirming the exact document list in advance is the difference between one trip and two.
If Something Looks Wrong After the Fact
If you get home and discover the name on the title doesn’t match the person who sold you the car, or the chain of ownership has a gap, you may have bought a title-jumped vehicle. Title jumping — reselling without ever putting the title in the reseller’s own name — is illegal in every state, and it can leave you with a vehicle you can’t register because of missing signatures, unpaid fees, or an undisclosed brand like salvage. Contact your state motor vehicle agency to find out what remedies exist in your state; depending on the circumstances, you may need to pursue the seller directly to get a usable title.
If the seller handed you only a bill of sale and promised the title later, do not drive the vehicle and do not consider the sale complete until a clean title in the seller’s name is in your hands.
Gifts and Inherited Vehicles Work a Little Differently
If you received the vehicle as a gift from a family member rather than buying it, the process still involves a title transfer and a trip to the motor vehicle agency, but many states reduce or waive sales tax on transfers between immediate family members. You’ll typically need a gift affidavit, provided by the agency, confirming that no money changed hands.
For an inherited vehicle, the paperwork depends on whether the estate goes through probate. Smaller estates can often use a simplified transfer with a small estate affidavit and a certified copy of the death certificate. Larger estates generally need a letter from the executor or administrator authorizing the transfer. Title transfer and registration fees still apply, but sales tax is generally not charged on inherited vehicles.
