Complete Guide: Car Bill of Sale
A car bill of sale is a legal document that records the transfer of ownership of a motor vehicle from a seller to a buyer, documenting the essential terms of the transaction: the vehicle's identity, the parties' names and addresses, the purchase price, the date of sale, and the vehicle's condition. While a bill of sale is not technically required to transfer vehicle ownership in most states—which accomplish that transfer through the assignment of the certificate of title—it serves essential evidentiary and practical functions: it provides both parties with a written record of the agreed terms, it protects the seller from liability for the vehicle after the sale date, it supports the buyer's tax basis documentation, and in some states it is required to complete the title transfer process with the DMV.
The distinction between a bill of sale and a certificate of title is fundamental to understanding how car sales are legally completed. The certificate of title is the official government document establishing legal ownership of the vehicle; ownership transfers when the seller signs the title's assignment section and the buyer registers the vehicle in their name with the DMV. A bill of sale is a private contract between the parties documenting the terms of the transaction. Both documents are typically required for a complete transaction: the title assignment transfers legal ownership; the bill of sale documents the price, condition representations, and warranty status. Some states require the bill of sale to be presented to the DMV as part of the title transfer application.
Car bills of sale must address two critical issues that distinguish private vehicle sales from dealer sales. First, the "as-is" vs. implied warranty question: private sellers typically sell vehicles "as-is," meaning without any warranty as to the vehicle's condition. However, under the UCC, selling a vehicle without expressly disclaiming implied warranties may leave the seller exposed to warranty claims if the car has significant defects. A properly drafted as-is bill of sale explicitly disclaims all express and implied warranties, shifting the risk of unknown defects to the buyer. Second, the odometer disclosure: federal law (the Truth in Mileage Act) requires sellers of motor vehicles to disclose the odometer reading at the time of sale on a federally prescribed form; states may incorporate this disclosure into the title transfer or bill of sale process.
For buyers, the car bill of sale provides documentation of the purchase price that is essential for several purposes: calculating the sales tax owed on the transaction (buyers must typically pay sales tax based on the declared purchase price or a minimum assessed value); establishing the cost basis for depreciation if the vehicle is used for business; and providing evidence of the agreed purchase price if the seller later claims the vehicle was not actually sold or disputes the consideration paid. Buyers should insist on receiving a complete bill of sale even in informal private party transactions and should verify that the price stated in the bill of sale is the actual price paid—not a reduced price intended to minimize sales tax.
How to Create a Car Bill of Sale: Step-by-Step
- 1
Verify the Vehicle's Ownership and Lien Status
Before finalizing any car sale, the buyer should verify that the seller actually owns the vehicle and that the title is clear of liens. Review the certificate of title to confirm the seller's name matches, that there are no lienholder entries (indicating an outstanding auto loan), and that the title is not branded as salvage, rebuilt, or flood. Run a vehicle history report using the VIN to check for reported accidents, title problems, odometer discrepancies, and ownership history. Do not complete the purchase if the seller cannot produce a clean, lien-free title.
- 2
Complete the Bill of Sale with Required Information
The bill of sale must include: seller's full legal name and address; buyer's full legal name and address; vehicle year, make, model, body style, color, and VIN; odometer reading at time of sale; purchase price; date of sale; payment method; and any representations about the vehicle's condition or as-is nature. Some states have specific bill of sale requirements—consult your state DMV's website for required content and any prescribed forms.
- 3
Complete the Federal Odometer Disclosure
Federal law requires the seller to disclose the odometer reading on a form that may be incorporated into the title assignment or provided as a separate odometer disclosure statement. The seller must certify that the odometer reading reflects the actual mileage or, if not, disclose the discrepancy. Knowingly making a false odometer disclosure is a federal crime subject to significant penalties. The buyer should confirm the disclosed odometer reading matches the vehicle's dashboard reading before signing.

Execute Title Assignment and Bill of Sale Simultaneously
Have both parties sign the bill of sale. The seller simultaneously signs the title's assignment section (on the back of the title certificate), entering the buyer's name, the sale date, the sale price, and the odometer disclosure. Both documents should be signed at the same time, in person. Buyers should avoid purchasing vehicles where the seller provides a title with a blank assignment (title jumping) or where the seller's name on the title does not match the person selling the car.
- 5
Complete DMV Registration and Tax Payment
After receiving the assigned title and bill of sale, the buyer must register the vehicle with the state DMV, pay applicable sales tax (or use/excise tax in some states), and obtain new license plates and registration. The timeline for completing registration varies by state—most states require registration within 30 days of purchase. Operating a vehicle with an unregistered transfer exposes the buyer to fines and may affect insurance coverage.
Key Legal Considerations
As-Is Sales and Implied Warranty Disclaimer
Private vehicle sales are typically "as-is" sales—the seller makes no representations about the vehicle's condition and disclaims all warranties. However, implied warranties of merchantability and fitness for a particular purpose arise under UCC Article 2 unless expressly disclaimed. To effectively disclaim these warranties, the disclaimer must: use the words "as-is" or "with all faults" (either phrase is specifically identified in UCC § 2-316 as sufficient); be in a writing that is part of the contract; and be conspicuous. The bill of sale should include a clearly visible, bold or capitalized as-is disclaimer to ensure the implied warranty disclaimer is effective.
Odometer Fraud and Federal Liability
The federal Odometer Act (49 U.S.C. § 32710) imposes substantial penalties on sellers who knowingly make false odometer disclosures—civil penalties of $10,000 per violation or three times actual damages, whichever is greater, plus attorney's fees. Vehicle sellers must disclose the actual mileage to the best of their knowledge; if the actual mileage is unknown (because the odometer was replaced or malfunctioned), the seller must disclose that the mileage is "not actual" and certify that the stated reading may not reflect actual mileage. Buyers who discover odometer fraud have strong federal and state remedies.
Salvage, Rebuilt, and Flood Titles
Vehicles that have sustained damage exceeding a threshold percentage of their value may receive branded titles—"salvage," "rebuilt," "flood," or "junk" designations—that must be disclosed when the vehicle is sold. Selling a vehicle with a branded title while representing it as clean title is fraud. Buyers should always check the title brand before purchasing and should verify any claims about prior damage through a vehicle history report. Some states require specific disclosure language for vehicles with branded titles on the bill of sale.
Seller's Continuing Liability After the Sale
Until the vehicle is re-registered in the buyer's name, the seller's name may remain associated with the vehicle in government records—creating risk that the seller will be contacted about parking tickets, toll violations, or more seriously, accidents caused by the buyer. A bill of sale with the sale date, the buyer's name, and the odometer reading protects the seller against these post-sale liabilities. Many states also have a "release of liability" form (separate from the bill of sale) that the seller can file with the DMV to officially record the transfer and protect against post-sale violations.
Common Mistakes to Avoid
Allowing Title to Be Assigned Without Receiving Full Payment
Once the seller signs the title assignment, the buyer has the legal right to register the vehicle—even if they have not yet paid in full. Never sign the title assignment before receiving full payment in a form you are certain is good funds: cash, cashier's check from a known bank (verify with the bank before accepting), or a confirmed wire transfer. Personal checks can bounce days after the sale is completed; bank-verified cashier's checks are safer.
Not Including an As-Is Disclaimer Prominently
Private sellers who do not include a clear, conspicuous as-is disclaimer in the bill of sale may face warranty claims if undisclosed defects are discovered after the sale. Include the as-is disclaimer in capitalized or bold text—"VEHICLE IS SOLD AS-IS, WITH ALL FAULTS, AND SELLER MAKES NO WARRANTIES EXPRESS OR IMPLIED"—and ensure the buyer acknowledges this language separately with their initials.
Selling a Vehicle With a Lien Without Payoff Coordination
If the seller still owes money on the car, there is a lien on the title that must be satisfied before the title can be transferred. The seller cannot simply hand over the title—the lienholder holds it. The transaction must be structured to pay off the lien simultaneously with the sale: often by having the buyer's funds directed to pay off the lender first, with any excess going to the seller. Alternatively, transactions can close at the lending institution. Do not try to sell a liened vehicle by taking the buyer's money first and promising to pay off the loan later.
Using a Different Sale Price in the Bill of Sale Than What Was Actually Paid
Some buyers and sellers agree to state a lower price in the bill of sale to reduce the buyer's sales tax liability. This is tax fraud—both parties may be liable for the understated tax plus penalties. The DMV in most states computes sales tax on the greater of the stated price or a minimum book value, so understating the price often fails to save any tax. State the actual price paid.
Not Filing a Release of Liability After the Sale
After completing the sale and signing the title over to the buyer, file a release of liability with your state DMV immediately. This documents that you transferred the vehicle on a specific date and protects you from liability for traffic violations, accidents, or other incidents caused by the buyer after the sale date. Do not wait for confirmation that the buyer has registered the vehicle—file the release immediately.
