A bill of sale and a title are two different documents that do different jobs, and you need both when you buy a used car from a private seller.
A bill of sale is a receipt — it documents that money changed hands and shows the date, the vehicle details, the price, and the signatures of both buyer and seller. It proves you bought the car and from whom. A title is the government document that proves who owns the vehicle. The title has the vehicle identification number (VIN), the registered owner's name, and any liens against the car. When you buy a car, the seller signs the title over to you, and you submit it to your state's motor vehicle department to register it in your name.
The bill of sale protects you if a dispute arises later — it shows you paid for the car and when. The title is what the state recognizes as proof of ownership. You cannot legally drive the car without eventually getting the title in your name, but you can drive it home from the sale with a bill of sale while you wait for the title transfer to process.
Key Takeaways
- A bill of sale is a receipt showing the buyer, seller, price, and vehicle details; a title is the government ownership document issued by your state.
- You need both documents when buying from a private seller — the bill of sale as proof of purchase and the title to register the vehicle in your name.
- The seller must sign the title over to you; without their signature on the title, you cannot complete the registration transfer.
- If the seller cannot produce the title, do not complete the purchase — a missing title means a lien or other claim may exist against the vehicle.
- The bill of sale should include the VIN, odometer reading, sale price, and signatures of both parties, and you should keep a copy for your records.
What a Bill of Sale Actually Covers
A bill of sale is a written record of the transaction. It should include the vehicle identification number (VIN), the make and model, the year, the odometer reading at the time of sale, the sale price, the date of sale, and the printed names and signatures of both the buyer and seller. Some states require the seller's address and driver's license number as well. You can write one on a blank piece of paper or use a template — your state's motor vehicle department website usually has one you can read for free.
The bill of sale protects you by creating a paper trail. If the seller later claims they did not sell you the car, or if there is a dispute about the price or condition, the bill of sale is your proof. It also documents the odometer reading, which matters if you later discover the mileage was rolled back. Keep a copy for your records and give the seller a copy as well.
What a Title Is and Why You Need It
The title is a certificate issued by your state that lists the legal owner of the vehicle. It includes the VIN, the current owner's name and address, the vehicle's make and model, the year, and whether there are any liens on the car. A lien means a bank, credit union, or other lender has a claim on the vehicle because the seller still owes money on it. The title also shows the vehicle's history — whether it has been branded as salvage, flood-damaged, or rebuilt.
When you buy a car, the seller must sign the title over to you. The signature line on the back of the title is where the seller releases ownership. You then take that signed title to your state's motor vehicle department and submit it along with the bill of sale, proof of insurance, and a completed registration form. The state then issues a new title in your name.
When the Seller Still Owes Money on the Car
If the seller has a lien on the title — meaning a lender still has a claim on the vehicle — the lender's name will appear on the title. The seller cannot legally transfer ownership to you until the lien is paid off. Before you hand over money, ask the seller to contact their lender and find out the payoff amount. Many private sales close with the lender's payoff coming directly from the sale proceeds.
The safest way to handle this is to meet at the lender's office or a bank, where the payoff can be processed when ready and the title released. If that is not possible, some title companies or attorneys will hold the money in escrow until the lien is cleared and the title is released. Never give the seller cash and trust that they will pay off the lien — you could end up owning a car that the lender can repossess.
What Happens If the Seller Cannot Produce the Title
If the seller does not have the title, stop the transaction. A missing title is a red flag. It could mean the seller lost it, but it could also mean there is an outstanding lien, the car was reported stolen, or the seller is not actually the legal owner. Some states allow you to request a duplicate title from the motor vehicle department, but only if you are the registered owner — the seller would have to do this themselves, and if they will not, that is a problem.
In rare cases, a seller might offer to sell you the car "as-is" without a title, claiming they will get it later. Do not accept this. You cannot legally register the vehicle without the title, and you have no proof of ownership if a dispute arises. If the seller is unwilling or unable to produce the title before the sale, walk away.
Differences Between Private Sales and Dealer Sales
When you buy from a dealer, the dealer handles the title transfer and registration for you — that is part of what you are paying for. The dealer will give you a bill of sale (or a purchase agreement that serves the same purpose) and will submit the signed title to the state on your behalf. You will receive your new title in the mail within a few weeks.
When you buy from a private seller, you are responsible for getting the title transferred. You must obtain the signed title from the seller, complete the registration form, and submit both to your state's motor vehicle department yourself. Some states allow you to do this online; others require you to visit in person. The bill of sale is your proof that you purchased the vehicle and your protection if anything goes wrong.
How to Protect Yourself During a Private Sale
Before you hand over money, verify that the seller's name matches the name on the title. Check the VIN on the title against the VIN on the car itself — the VIN is stamped on the driver's side door jamb and on the engine block. Run a vehicle history report using the VIN through a service like Carfax or AutoCheck to see if there are any liens, accidents, or title brands. Ask the seller for their driver's license and write down their information on the bill of sale.
Get the title signed over to you in front of a witness if possible, or at least have the seller sign and date the back of the title where it says "Signature of Seller." Take a photo of the signed title before you leave. Do not accept a title that has been altered, crossed out, or corrected with white-out — some states will not accept it, and it is a sign something is wrong. Once you have the signed title and bill of sale, you can drive the car home and complete the registration transfer at your convenience.
Frequently Asked Questions
Can I drive a car home if I do not have the title yet?
Yes, if you have a bill of sale signed by the seller. You can drive the car with the bill of sale as proof of purchase while you arrange to get the title transferred. However, you must complete the title transfer within the time frame your state allows — usually 10 to 30 days — or you risk a fine.
What if the title has the wrong name on it?
If the title lists a different name than the person selling you the car, do not complete the purchase. The person whose name is on the title is the legal owner, and they are the only one who can sign it over to you. Ask the seller to explain the discrepancy and to bring documentation proving they are the owner.
Do I need a bill of sale if I buy from a dealer?
Dealers provide a purchase agreement that serves the same purpose as a bill of sale. You do not need a separate bill of sale, but you should keep the purchase agreement for your records. The dealer will handle the title transfer for you.
What should I do if the seller wants to sign the title blank?
Do not accept a blank signature. The seller must sign the title in front of you, and you should verify that the signature matches the one on their driver's license. A blank signature creates a gap in the chain of ownership and can cause problems when you try to register the car.
Can I buy a car without seeing the title first?
No. Always see and inspect the title before you agree to buy the car. Check that the seller's name matches the title, that there are no liens listed, and that the title is not damaged or altered. If the seller refuses to show you the title, that is a reason to walk away from the deal.
