What documents do you need to sell a car? It varies by state, but generally a signed title, and often a bill of sale and an odometer disclosure. Some states also require a notarized title or a release of liability. Check your state’s specific requirements before the sale so nothing holds up the transfer.
The paperwork required to sell a car is one of the most-searched and most-confusing parts of the process, mostly because the requirements vary by state. A transaction that needs only a signed title in one state needs a notarized title, a bill of sale, and an odometer disclosure in another. Getting the paperwork right matters because mistakes can delay the sale, create liability after the sale, or in some cases void the transfer.
This piece covers the documents needed to sell a car in 2026, including the federal requirements that apply everywhere and the state-specific variations that trip up sellers. Our broader guide on documents needed to sell a car covers the process in depth; this post focuses on the state-by-state differences and 2026 updates.

The Documents Required Everywhere
The Vehicle Title
The title is the core document in any car sale. To transfer ownership, you sign the title over to the buyer in the designated seller section. If there is a lien (you still owe money), the lender holds the title and it must be released before transfer. A clean title in your name is the single most important document for a smooth sale.
Odometer Disclosure
Federal law requires an odometer disclosure for most vehicles at the time of sale. For vehicles model year 2011 and newer, this requirement now extends to 20 years from the model year (a federal rule change phased in over recent years). The disclosure is usually part of the title itself but may be a separate form in some states. Vehicles over 20 years old and vehicles over a certain weight are typically exempt.
Bill of Sale
A bill of sale documents the transaction: the sale price, the date, the parties, and the vehicle details. Some states require it; others do not but it is good practice everywhere. The bill of sale protects both parties by creating a record of the transaction terms.
State-Specific Variations That Trip Up Sellers
States Requiring Notarized Titles
A handful of states require the title to be notarized at the time of signing. These include Arizona, Kentucky, Louisiana, Montana, North Carolina, Ohio, Oklahoma, Pennsylvania, West Virginia, and Wyoming. In these states, you and sometimes the buyer must sign the title in front of a notary. Skipping this step can void the transfer. If you are in one of these states, plan to complete the title signing at a bank or notary office.
States Requiring a Separate Bill of Sale
Some states require a specific state-issued bill of sale form rather than a generic one. Examples include West Virginia (DMV-7-TR), and several others that have specific forms. Using a generic bill of sale when the state requires its specific form can delay the buyer’s registration.
States With Smog or Emissions Requirements
California, and to varying degrees states with emissions testing programs, require a valid smog certificate at the time of sale for most vehicles. In California specifically, the seller is responsible for providing a smog certification that is less than 90 days old at the time of transfer, with some exemptions for newer vehicles and certain transactions. Selling without the required smog certificate creates problems for the buyer’s registration.
States Requiring License Plate Return or Transfer
States differ on what happens to license plates. In some states (like New York and Pennsylvania), plates stay with the seller and must be removed before the sale and either transferred to another vehicle or surrendered. In other states, plates transfer with the vehicle. Knowing your state’s rule prevents registration and liability issues.
States Requiring a Release of Liability
Many states have a release of liability or notice of transfer form that the seller files with the DMV to formally end their responsibility for the vehicle. California (the NRL form), and many other states have versions of this. Filing it protects you from liability for anything the buyer does with the vehicle after the sale (parking tickets, tolls, accidents). This is one of the most important steps for seller protection and one of the most commonly skipped.

Special Documentation Situations
Selling a Car With a Lien
If you still owe money, the lender holds the title. You cannot transfer ownership until the loan is paid off and the lien is released. The process involves getting a payoff quote, paying off the loan (or having the buyer’s payment routed to the lender), and the lender releasing the title. This adds time to the transaction and requires coordination with the lender.
Selling a Car With a Lost Title
If you cannot find the title, you need to apply for a duplicate from your state DMV before you can sell. This takes anywhere from a few days to a few weeks depending on the state. Start the duplicate title process well before you plan to sell if you cannot locate the original.
Selling a Car You Inherited
Selling a vehicle from an estate or inherited vehicle requires additional documentation: typically the death certificate, proof of your authority to sell (executor documentation or similar), and sometimes a transfer of title through the estate before you can sell to a third party. The exact requirements vary by state and by whether the vehicle went through probate.
How Dealer Sales Simplify the Paperwork
One of the underappreciated advantages of selling to a dealer is that the dealer handles most of the paperwork. Licensed dealers process title transfers, odometer disclosures, and the state-specific requirements as part of their normal business operations. You sign the title and the required forms; the dealer handles the filing, the registration coordination, and the release of liability. Our guide on what happens when you sell to a dealer covers the full process.
For sellers who find the state-specific paperwork daunting, this is a meaningful reason to consider a dealer sale even though the price is typically lower than a private sale. The paperwork simplification, combined with the elimination of scam risk and the speed of the transaction, is the tradeoff for the lower price. Our guide on selling safely covers the protection side.
Frequently Asked Questions
What documents do I need to sell a car?
Everywhere you need the vehicle title (signed over to the buyer), an odometer disclosure (required by federal law for most vehicles within 20 years of the model year), and ideally a bill of sale. State-specific requirements may add a notarized title, a state-specific bill of sale form, a smog or emissions certificate, license plate handling, and a release of liability filing. The exact requirements depend on your state.
Do I need a notary to sell my car?
In some states, yes. Arizona, Kentucky, Louisiana, Montana, North Carolina, Ohio, Oklahoma, Pennsylvania, West Virginia, and Wyoming require the title to be notarized at signing. In these states you must sign the title in front of a notary, and skipping this step can void the transfer. Most other states do not require notarization. Check your specific state’s requirement before completing the sale.
What is the paperwork to sell a car in California?
California requires the signed title, an odometer disclosure, and a smog certification less than 90 days old at the time of transfer (with exemptions for newer vehicles and certain transactions). California sellers should also file a Notice of Release of Liability (NRL) with the DMV to formally end their responsibility for the vehicle. The release of liability is one of the most important steps for protecting yourself from liability after the sale.
What is a release of liability and do I need to file one?
A release of liability (or notice of transfer) is a form filed with your state DMV that formally ends your responsibility for the vehicle after you sell it. It protects you from liability for what the buyer does with the vehicle (parking tickets, tolls, accidents) after the sale. Many states have a version of this form, and filing it is one of the most important and most commonly skipped seller protection steps. File it as soon as the sale is complete.
How do dealer sales handle the paperwork differently?
Licensed dealers handle most of the paperwork as part of their normal operations. They process the title transfer, odometer disclosure, and state-specific requirements, coordinate the registration, and handle the release of liability. You sign the title and required forms, and the dealer manages the rest. This paperwork simplification is one of the main advantages of selling to a dealer, alongside speed and the elimination of scam risk, in exchange for a typically lower price than a private sale.
