StableWhy Every Car Sale Needs a Bill of Sale
A bill of sale is your legal proof that a transaction occurred. Without it, you have no documentation of what was purchased, for how much, or when ownership transferred. This creates problems for:
- Registering the vehicle at the DMV
- Proving purchase price for insurance claims
- Calculating and paying correct sales tax
- Resolving disputes about vehicle condition
- Defending against claims from the previous owner

Check Your State DMV
Requirements change and vary significantly by state. Before any private sale, visit your state DMV website for current bill of sale requirements, forms, and whether notarization or witnesses are needed.
As-Is Language for Sellers
Sellers should include as-is language to protect against post-sale claims. Standard as-is language:
“This vehicle is sold AS-IS with no warranties expressed or implied. The buyer has inspected the vehicle and accepts it in its current condition. The seller makes no guarantees regarding the mechanical condition, safety, or fitness for any particular purpose.”
As-Is Does Not Cover Fraud
As-is language protects sellers from complaints about known issues the buyer could have discovered through inspection. It does NOT protect against fraud, intentional misrepresentation, or concealing known defects. Always disclose known problems.
Common Bill of Sale Mistakes
| Mistake | Consequence | How to Avoid |
|---|---|---|
| No bill of sale | No proof of purchase, tax issues | Always create one regardless of state |
| Wrong VIN | Registration problems, fraud suspicion | Triple-check VIN against title and dashboard |
| Incorrect sale price | Tax fraud liability | Report actual sale price paid |
| Missing signatures | Document not legally binding | Both parties sign in person |
| No date | Unclear ownership transfer timing | Include exact date of transaction |
| No odometer reading | Federal violation, future liability | Record exact mileage at sale |
Odometer Disclosure Requirements
Federal law requires odometer disclosure for vehicles under 20 years old. The bill of sale or a separate odometer disclosure statement must include:
- Exact odometer reading at time of sale
- Whether odometer reflects actual mileage
- Declaration if odometer has rolled over (exceeded max reading)
- Disclosure if odometer reading is not actual mileage
What to Do If Seller Refuses Bill of Sale
Walk away immediately. A seller refusing to provide a bill of sale indicates:
- Potential stolen vehicle
- Title problems they are hiding
- Intent to deny the sale later
- Tax evasion attempts
- General dishonesty
How Long to Keep Your Bill of Sale
Keep all bills of sale for at least 7 years. You may need them for:
- IRS audit (up to 7 years for tax returns)
- Proof of purchase for insurance claims
- Establishing vehicle history when selling
- Resolving title disputes
- Legal proceedings related to the vehicle
Always get a bill of sale for every private car purchase
A proper bill of sale protects both buyer and seller, satisfies state requirements, and provides documentation for taxes, insurance, and potential disputes. Include VIN, price, odometer, date, and both parties' full information with signatures.
