What Paperwork Do I Need to Buy a Used Car?
When buying a used car from a private seller, the buyer's main job is verifying the seller's paperwork is correct, then submitting the right documents to the DMV to register the vehicle in your name. What you need is mostly consistent across states — with important differences in deadlines, forms, and fees.
Quick answer
Used car buyers typically need:
- ✓ From the seller: Signed title (with odometer disclosure), bill of sale, lien release if applicable
- ✓ For the DMV: Title transfer application, government-issued ID, proof of insurance
- ✓ Payment for: Title transfer fee + sales or use tax on the purchase price
The exact forms and deadlines depend on your state. Title transfer deadlines range from 10 days (California, Louisiana) to 30–60 days in other states.
Documents to get from the seller
The seller is responsible for providing these. Review them carefully before handing over payment — errors on the title are your problem once you've paid.
Signed vehicle title
Required
The seller must sign the title in the designated transfer section. Verify the seller's name on the title matches their ID. If the title shows two owners connected by 'and,' both may need to sign.
Odometer disclosure
Required
Required by federal law for vehicles under 10 years old and under 16,000 lbs. Usually completed on the back of the title. The seller fills this in — it should not be blank.
Lien release (if applicable)
Conditional / Recommended
If the title shows a lienholder (bank or finance company), get written proof that the loan is paid off. Without a lien release, you'll receive a title with an encumbrance — meaning someone else has a legal claim on the vehicle.
Bill of sale
Conditional / Recommended
A written record of the sale: VIN, sale price, date, and both parties' information. Required in some states; recommended everywhere. The DMV may use it to calculate sales tax.
Title inspection checklist
Before you pay, check all of these. A title problem discovered after the money changes hands is much harder to resolve.
Seller's name on the title matches their government-issued ID
VIN on the title matches the VIN plate on the dashboard and the door jamb
No active lienholder listed, or a lien release is present
Title is not branded as salvage, rebuilt, flood, or otherwise damaged
No signs of alterations, whiteout, or tampering on the title
Odometer section is filled in (for vehicles under 10 years old)
Running a vehicle history report using the VIN (through services like CARFAX or NMVTIS) adds another layer of protection against undisclosed flood damage, salvage history, or odometer fraud.
Documents you need for the DMV
After the sale, you submit these to your state DMV (or county office, depending on your state) to register the vehicle in your name.
Title transfer application
Your state's DMV title/registration application form. Available at the DMV or online. Texas uses Form 130-U; California uses form REG 343; most states have their own.
Government-issued photo ID
Driver's license or other valid government ID. Required for identity verification when submitting transfer paperwork.
Proof of insurance
Most states require proof of minimum liability coverage before they'll issue plates. Some states require this at the time of title transfer too.
Payment for title fee and sales tax
Title transfer fees range from about $10 to $100 depending on state. Sales or use tax on the purchase price is due in most states. Some states calculate tax based on the higher of the sale price or the vehicle's book value.
Title transfer paperwork
Title transfer is the formal legal step where ownership moves from seller to buyer. Most states require you to submit the transfer paperwork within a set window after the purchase date. Missing that window usually means a late fee — it doesn't void the transfer, but it costs extra.
Bill of sale and odometer disclosure
These two documents serve different purposes and are often confused. The bill of sale records the transaction details and sale price. The odometer disclosure records the mileage at the time of sale and is a federal requirement on the title for most vehicles under 10 years old — the seller fills it in, not the buyer.

Frequently asked questions
What paperwork do I need to buy a used car from a private seller?
Buyers need the signed title from the seller with odometer disclosure completed, a bill of sale, proof of insurance, a valid government-issued ID, and payment for the title transfer fee and applicable sales or use tax.
How do I verify the title is clean?
Before paying, confirm the seller's name matches the title and their ID, the VIN on the title matches the car, there's no active lienholder, and the title isn't branded as salvage or flood-damaged. A vehicle history report using the VIN adds extra protection.
How long do I have to transfer the title after buying?
Deadlines vary by state. California and Louisiana require transfer within 10 days. Texas, Florida, and Georgia allow 30 days. Check your state's DMV for the exact window — late transfers typically incur a penalty fee.
Is a bill of sale required when buying a used car?
Some states require it; most recommend it. A bill of sale documents the purchase price (which many states use to calculate sales tax), the VIN, sale date, and both parties' information.
What's different about buying from a dealer vs. a private seller?
Dealers typically handle title transfer and registration paperwork on your behalf. With a private seller, you manage the DMV process yourself and must meet your state's transfer deadline.
