A bill of sale needs to carry the full legal names and addresses of the buyer and seller, the date of the transaction, the purchase price, a detailed description of what’s being sold, and both parties’ signatures. Vehicle sales add federally required details, chiefly the Vehicle Identification Number and an odometer disclosure. The question of what information needs to be on a bill of sale has a short answer and a long one, because leaving any required piece out — or getting it wrong — can make the document unenforceable and block the buyer from registering, insuring, or reselling the property later.
The Core Elements Every Bill of Sale Needs
The same backbone applies whether you’re selling a sofa, a boat, or a tractor.
Full Legal Names and Addresses
Use the full legal name of each party as it appears on a government-issued ID, along with a current street address. No nicknames. No business names unless the sale actually involves a business entity. Check the spelling against a driver’s license, because a misspelled name on a bill of sale can delay a title transfer or a registration.
The Date of the Transaction
Write the exact date the sale takes place. That date establishes when ownership transfers and when any deadlines for title registration or tax filing start running. If the signing date is different from the date money changes hands, put both on the document.
Purchase Price and Payment Method
Write the final price in numerals and in words, for example “$8,500 / Eight Thousand Five Hundred Dollars.” If the two versions don’t match, the written-out version typically controls. Record how payment was made: cash, check, money order, or electronic transfer. If the buyer is paying in installments, write out the payment schedule, the amounts, and what happens if a payment is missed.
A Detailed Description of the Property
Describe the item with enough specificity that nothing else could be confused with it. For general goods, that means make, model, color, dimensions, condition, and any serial numbers or unique markings. “One couch” is almost useless in a dispute. “One brown leather three-seat sofa, Ashley Furniture model 3590138, serial number AF-20241587” leaves no room for argument.
Extra Details Required for Vehicle Sales
Motor vehicles are regulated assets, and a motor vehicle agency won’t process a title transfer without specific identifying information on the bill of sale.
Vehicle Identification Number
Every motor vehicle has a 17-character VIN assigned under federal standards.1eCFR. 49 CFR 565.13 General Requirements You’ll find it on a metal plate at the base of the windshield on the driver’s side, on the driver’s door jamb sticker, and on the title itself. Copy it character by character. Transposing one digit can derail the title transfer.
Make, Model, Year, and Body Type
List the make (Toyota), model (Camry), model year, and body type (sedan, pickup, SUV). These need to match the current title exactly. Inconsistencies between the bill of sale and the title are a common reason motor vehicle agencies reject transfer applications.
Odometer Reading and Disclosure
Federal law requires the seller to disclose the vehicle’s mileage at the time of transfer. The disclosure must include the odometer reading, a statement about whether that reading is accurate, and the signatures of both parties.2eCFR. 49 CFR 580.5 Disclosure of Odometer Information If the odometer has rolled over its mechanical limit or the seller knows the reading is inaccurate, the disclosure has to say so explicitly. Providing false mileage information can bring federal fines and imprisonment.
Older vehicles get an exemption. Vehicles with a model year of 2010 or earlier are exempt from odometer disclosure. For vehicles from model year 2011 onward, the exemption doesn’t apply until the vehicle is at least 20 years old from its model year, meaning the first 2011 models won’t qualify until 2031.3eCFR. 49 CFR 580.17 Exemptions If the vehicle qualifies, note on the bill of sale that the odometer reading is exempt rather than leaving the field blank.
Clauses That Make the Document Enforceable
The transaction facts form the backbone. A few standard clauses turn the paper from a receipt into something that will hold up if a dispute surfaces.
As-Is Language
Most private sales happen “as is,” meaning the buyer accepts the item in its current condition, faults and all. Under the Uniform Commercial Code, phrases like “as is” or “with all faults” eliminate implied warranties, including the implied warranty that goods are fit for ordinary use.4Legal Information Institute. UCC 2-316 Exclusion or Modification of Warranties Without that language, a buyer could argue the seller implicitly guaranteed the item worked properly, even if nothing was ever said about condition.
Any Warranty the Seller Does Give
If the seller wants to make a guarantee, say a 30-day warranty on a used appliance, it has to be written into the bill of sale with specifics: what’s covered, for how long, and what remedy the buyer gets (repair, replacement, or refund). Verbal promises are hard to enforce. If it’s not on paper, assume it doesn’t exist.
Lien-Free Statement
Include a statement from the seller confirming the property is free of liens — no lender or creditor has a legal claim against it. This matters most with vehicles, where an outstanding auto loan creates a lien on the title. If you buy a car with an undisclosed lien, the lender can repossess it from you even though you paid the seller in full. Before closing, check the title for any lienholder notation, and make sure the bill of sale explicitly states the item is sold free and clear.
Signatures, Witnesses, and Notarization
Both parties must sign, with the date of each signature next to it. Under the UCC, a contract for goods over $500 is enforceable only against the party who signed it, so if only the seller signs, the buyer can walk away, and vice versa.5Legal Information Institute. UCC 2-201 Formal Requirements; Statute of Frauds
A witness is a neutral person who observes the signing and can later confirm the identities of the signers and that nobody was coerced. The witness should print their name, sign, and include the date. For high-value items, this adds a useful layer of protection.
Some states require the bill of sale to be notarized before a motor vehicle agency will accept it for a title transfer. A notary public verifies identities using government-issued ID, witnesses the signatures, and applies an official seal. Even in states where notarization isn’t mandatory, a notarized bill of sale is much harder to challenge in court than an unnotarized one. Check with your state’s motor vehicle agency before the sale so you know what it requires.
Writing the Price Honestly
Some buyers and sellers agree to write a lower price on the bill of sale to reduce the sales tax owed at registration. That’s tax fraud, and state revenue agencies actively look for it. Many states calculate the tax owed on the listed price or the vehicle’s fair market value, whichever is higher, so understating the price doesn’t always save money and it creates criminal exposure for both parties.
Transactions listed as “$0” or “$1” get extra scrutiny. If you’re genuinely gifting property, write that on the bill of sale and note the relationship between the parties. The IRS requires gift tax reporting when the fair market value of a gift to any single person exceeds $19,000 in 2026.6Internal Revenue Service.

One boundary worth knowing: anyone in a trade or business who receives more than $10,000 in cash in a single transaction (or related transactions) must report it to the IRS on Form 8300.7Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 This applies to dealers and businesses, not to a one-time private sale between individuals. If you regularly sell vehicles or high-value goods, the threshold applies to you.
After You Sign
Signing the bill of sale isn’t the last step, especially for vehicles, where the seller’s name stays on the registration until the buyer completes the title transfer.
If you’re the seller, file a notice of transfer (sometimes called a release of liability) with your state’s motor vehicle agency as soon as the sale is complete. Until that notice is on file, you can be held responsible for parking tickets, toll violations, and even accidents involving a vehicle that’s technically still registered in your name. Most states let you submit this notice online, and the deadline is typically 30 days or less. Don’t wait for the buyer to handle their end.
If you’re the buyer, transfer the title into your name promptly. States set different deadlines, but most penalize late transfers with fees. Until the title is in your name, you don’t have clear legal ownership, which matters if the vehicle is stolen, damaged, or involved in an insurance claim.
Both parties should keep a signed copy of the bill of sale indefinitely. Store it with your other financial records. If a dispute surfaces years later about who owned what and when, that’s the document that settles it.
