What a bill of sale is and why Alabama requires one
A bill of sale is a written record that you and the buyer (or seller) sign to prove that a car has changed hands. In Alabama, the bill of sale serves as proof of the sale price, the condition of the vehicle, and who owned it before the transfer. The state does not legally require a bill of sale to complete a car sale, but the Alabama Department of Revenue uses it to calculate sales tax, and your insurance company will ask for it when you register the vehicle in a new owner's name.
Without a bill of sale, you have no written proof of the transaction. If a dispute arises later—about the price paid, the condition of the car, or who is responsible for repairs—you have no document to reference. For the seller, a bill of sale protects you by showing that you transferred ownership on a specific date. For the buyer, it proves you paid for the vehicle and establishes your right to register it.
Key Takeaways
- Alabama does not legally require a bill of sale, but the Department of Revenue needs one to calculate sales tax when you register the vehicle.
- The bill of sale must include the vehicle identification number (VIN), sale price, date of sale, and signatures from both buyer and seller.
- You can use the official Alabama form (Form MVT 2-1) or write your own bill of sale as long as it contains all required information.
- The buyer must bring the bill of sale to the county probate office along with the title and proof of insurance to complete registration.
- Keep a copy for your records; the original goes to the buyer, and a copy may be filed with the probate office depending on local practice.
What information must go on an Alabama bill of sale
The bill of sale must contain specific details so that it serves as a valid record of the transaction. Include the full legal name and address of the seller, the full legal name and address of the buyer, the date of the sale, and the sale price in dollars. You must also list the vehicle's VIN (vehicle identification number, found on the dashboard or title), the year, make, model, and color of the car, and the current odometer reading.
Both the seller and buyer must sign and date the document. Some people add a line for the seller to confirm the condition of the vehicle (for example, "sold as-is" or "with warranty") to prevent later disputes. If the car is being sold by someone other than the registered owner—such as a power of attorney or estate representative—that person must sign and their relationship to the owner should be noted.
The bill of sale does not need to be notarized in Alabama, though having it notarized adds an extra layer of proof if questions arise later. If you choose to have it notarized, the notary will witness the signatures and stamp the document, but this step is optional.
Using the official Alabama form or writing your own
Alabama provides an official bill of sale form called Form MVT 2-1, available on the Alabama Department of Revenue website. This form is straightforward and includes all the fields the state needs. You can print it, fill it out by hand or typewriter, and have both parties sign it. Using the official form removes any question about whether you have included the right information.
You are not required to use the official form. You can write your own bill of sale on plain paper as long as it includes all the required information: seller name and address, buyer name and address, VIN, vehicle year/make/model/color, sale price, date, odometer reading, and signatures from both parties. A handwritten bill of sale is legally valid in Alabama as long as it is legible and signed by both the seller and buyer.
Whichever format you choose, keep the language clear and straightforward. Avoid vague terms like "good condition" or "runs well"—instead, note specific details like "engine runs, transmission shifts, tires have 50% tread" or "sold as-is, no warranty." This prevents misunderstandings after the sale is complete.
How to handle the sale price and sales tax
Write the actual sale price on the bill of sale, not a lower amount. The Alabama Department of Revenue uses the price you list to calculate sales tax when the buyer registers the vehicle. If you understate the price to reduce the buyer's tax burden, you are committing tax fraud, and both buyer and seller can face penalties.
The buyer is responsible for paying sales tax when they register the car at the county probate office. In Alabama, sales tax on a vehicle is calculated as a percentage of the sale price (the rate varies by county but is typically around 10 percent when you combine state and local tax). The buyer will owe this tax at registration, so they should know the full sale price before they sign the bill of sale.
If the car is being sold between family members or in certain other circumstances, the buyer may be may have access to to a sales tax exemption. The bill of sale should note any exemption that applies, and the buyer will need to provide documentation of that exemption when they register the vehicle.
What happens after both parties sign
Once you and the buyer have signed the bill of sale, each party should keep a copy. The buyer will need their copy when they go to the county probate office to register the vehicle in their name. They will bring the bill of sale, the original title (signed over by the seller), proof of insurance, and payment for registration fees and sales tax.
The probate office will process the registration and issue a new title in the buyer's name. Some counties ask for a copy of the bill of sale to be filed with the registration; others do not. The buyer should ask the probate office whether they need to submit the bill of sale or if they only need to present it as proof of the transaction.
The seller should keep a copy of the signed bill of sale for their records. This protects you if questions arise later about when you sold the vehicle or what condition it was in at the time of sale. If the car is involved in an accident or legal issue after the sale, the bill of sale proves you no longer owned it.
Common mistakes to avoid when writing a bill of sale
Do not leave the sale price blank or write "cash" instead of a dollar amount. The Department of Revenue needs a specific number to calculate tax. Do not sign the bill of sale before the buyer has reviewed it and agreed to all terms. Once both parties sign, the document is binding.
Do not assume the buyer will handle registration right away. Some buyers wait weeks or months to register a vehicle, and in that time the seller may be contacted about unpaid parking tickets or other issues tied to the old registration. Make sure the buyer understands they must register the car in their name promptly, and keep your copy of the bill of sale to prove you transferred ownership on the date stated.
Do not cross out or white-out information on the bill of sale after it is signed. If you need to correct something, start over with a new form. Alterations to a signed document can raise questions about its validity. If the buyer or seller notices an error before signing, fix it and initial the change, but avoid changes after signatures are in place.
Frequently Asked Questions
Do I need a bill of sale if the buyer is paying with a check or loan?
Yes. The bill of sale documents the sale regardless of how payment is made. Write the sale price on the bill of sale even if the buyer is financing the car through a bank or credit union. The lender may also ask for a copy of the bill of sale as proof of the purchase price.
What if I am selling a car with a lien on the title?
The bill of sale should note that the vehicle has a lien and that the seller will pay off the lien before transferring the title. The buyer should not sign the bill of sale until they understand that the title cannot be transferred until the lender releases the lien. This is typically handled through the lender's payoff process, not through the bill of sale itself.
Can I use a bill of sale from another state?
You can, but it is safer to use the Alabama form or write one that follows Alabama's requirements. A bill of sale from another state may not include all the information Alabama's Department of Revenue needs, and the probate office may ask for additional documentation. Using the Alabama form ensures you have everything in one place.
What if the seller will not sign the bill of sale?
Do not complete the purchase. A bill of sale protects both parties, and a seller who refuses to sign raises a red flag. The seller may not have clear title to the vehicle, or there may be an outstanding loan or lien. Walk away from the deal unless the seller can explain why they will not sign and resolve the issue.
Do I need to register the bill of sale with the state?
No. You do not file the bill of sale with the state. The buyer brings it to the county probate office when they register the vehicle, and the probate office may keep a copy or straightforward note that it was presented. The bill of sale is a record between the buyer and seller, not a state filing.
