A handwritten bill of sale is legally valid in all 50 states if it contains the right information and is signed by both the buyer and seller

You do not need a printed form or a notary to create a bill of sale for a car. A handwritten document works just as well, provided it includes the vehicle identification number (VIN), the sale price, the date, and signatures from both parties. The document serves as proof of ownership transfer and protects both buyer and seller by creating a record of the transaction.

The main risk with a handwritten bill of sale is leaving out a required detail or writing it in a way that creates confusion later. A missing VIN, for example, can make it harder for the buyer to register the car. An unclear price or payment terms can lead to disputes. The document does not have to be fancy, but it does have to be complete and legible.

Key Takeaways

  • A handwritten bill of sale must include the VIN, sale price, date, and signatures from both buyer and seller to be legally valid.
  • The document should list the vehicle's make, model, year, and current odometer reading to prevent future ownership disputes.
  • Both parties should keep a copy of the signed bill of sale, and the buyer will need it when registering the car with the state.
  • State motor vehicle departments do not require a specific form, but some states have optional templates that follow their rules.

What information must go in a handwritten bill of sale

Start with the vehicle details. Write the year, make, model, and body style (sedan, truck, SUV, etc.). Then write the VIN exactly as it appears on the title or registration — this is the 17-character code that uniquely identifies the car. Include the current odometer reading. These details prevent confusion if either party later claims the wrong car was sold.

Next, write the sale price in both numbers and words. For example: "$5,000 (five thousand dollars)". This prevents disputes over whether the price was $500 or $5,000. State whether the sale is cash, payment plan, trade-in, or another arrangement. If the buyer is paying in installments, write the payment schedule — for example, "$2,000 down, $1,500 on [date], $1,500 on [date]".

Add the date of the sale and the full legal names and addresses of both the buyer and seller. Some states require the seller to disclose the title status — whether the title is clear (no liens), has a lien against it, or is branded (salvage, rebuilt, flood damage, etc.). Check your state's motor vehicle department website to see if this disclosure is required where you live.

How to structure and sign the document

Write the bill of sale on plain paper or use a template from your state's motor vehicle department website. Start with a heading like "Bill of Sale" at the top. Then list each piece of information in a clear order: seller name and address, buyer name and address, vehicle details, sale price, and payment terms.

Both the buyer and seller must sign and date the document in ink. Some states require the signature to be notarized; most do not. If your state does require notarization, a notary public will witness the signatures and stamp the document. You can find notaries at banks, UPS stores, or online through the National Notary Association. Notarization costs between $5 and $25 per signature, depending on your location.

Make at least two copies — one for the buyer and one for the seller. The buyer will need the original or a certified copy when registering the car. Keep your copy in a safe place in case a dispute arises later.

State-specific requirements and title transfer rules

Most states do not mandate a specific bill of sale form, but some provide optional templates on their motor vehicle department website. A few states — including Georgia, Illinois, and Kentucky — have specific language or formatting they prefer, though a handwritten document that includes all required information is still valid.

The bill of sale is separate from the title transfer. After both parties sign the bill of sale, the seller must sign the back of the title (or the title process, depending on the state) and give it to the buyer. The buyer then takes both documents to the motor vehicle department to register the car in their name. Some states require the bill of sale to be notarized before the title can be transferred; others do not.

A few states — such as Texas and Florida — allow the buyer to register the car without a bill of sale if the title is signed over, but having one protects both parties and is worth the few minutes it takes to write. Check your state's motor vehicle department website for the exact steps and any forms they require.

Common mistakes to avoid when writing a bill of sale

The most frequent error is writing the VIN incorrectly or leaving it out entirely. The VIN appears on the title, the registration, and the dashboard (visible through the windshield on the driver's side). Copy it exactly, character by character. A wrong VIN can delay or block registration.

Another common mistake is writing the price in words only or numbers only. Write it both ways to prevent the buyer or seller from later claiming a different amount was agreed to. Similarly, do not leave the payment terms blank. If it is a cash sale, write "cash at time of sale" or "full payment at signing".

Do not sign the document in pencil or with a signature that is illegible. Use pen and sign your full legal name as it appears on your driver's license. If either party uses a nickname or goes by a different name than what is on their ID, write the legal name on the bill of sale and note the nickname separately if needed.

Avoid crossing out or using white-out to make changes. If you make a mistake, start over on a fresh page. A document with multiple corrections can raise questions during registration or if a dispute arises.

What happens after both parties sign

The buyer should take the signed bill of sale and the signed title to the motor vehicle department within the timeframe required by their state — usually 10 to 30 days after the sale. The department will issue a new registration and title in the buyer's name. The seller should keep a copy of the signed bill of sale as proof that they no longer own the vehicle, in case the buyer fails to register it and the car is later involved in an accident or crime.

If the car has a lien (the seller still owes money on it), the lender must sign off on the title before it can be transferred. The seller is responsible for paying off the loan before the title can be given to the buyer. The bill of sale should note whether the sale is contingent on the lien being paid off.

If a dispute arises after the sale — for example, the buyer claims the car was damaged and wants money back, or the seller claims the buyer never paid — the bill of sale is the primary document proving what was agreed to. This is why clarity and completeness matter.

Frequently Asked Questions

Do I need to notarize a handwritten bill of sale?

Most states do not require notarization for a bill of sale to be valid. However, a few states recommend it or require it for title transfer. Check your state's motor vehicle department website to confirm. Notarization costs $5 to $25 and adds a layer of legal protection, so it is worth doing even if not required.

What if I lose my copy of the bill of sale after I sell the car?

If you are the seller and lose your copy, you can ask the buyer for a duplicate. If the buyer refuses or cannot be reached, contact your state's motor vehicle department — they may have a record of the title transfer. Keep your copy in a safe place for at least three to five years after the sale.

Can I use a bill of sale instead of transferring the title?

No. The bill of sale proves the sale happened, but the title transfer proves ownership. You must do both. The seller signs the title, and the buyer takes both the signed title and the bill of sale to the motor vehicle department to complete the registration.

What if the seller will not sign the bill of sale?

Do not complete the purchase. A seller who refuses to sign a bill of sale is a red flag — it suggests they may not own the car, the title may be unclear, or they are trying to avoid a record of the sale. Walk away from the deal.

Can I write a bill of sale on my phone or computer and print it instead of handwriting it?

Yes. A printed bill of sale is just as valid as a handwritten one, as long as it contains all required information and is signed in ink by both parties. Many people use a template from their state's motor vehicle department website and print it out.
