Bill of Sale: What to Include So the Deal Actually Sticks

A Handshake Isn’t a Bill of Sale

You’re selling your used car to a coworker for $8,500. Or buying a commercial espresso machine from a coffee shop that’s closing down for $3,200. Or purchasing a used boat from someone you found on Facebook Marketplace for $15,000.

In each of these situations, you need a bill of sale. It’s one of the simplest legal documents out there, but skipping it --- or getting it wrong --- creates problems that range from annoying to expensive.

A bill of sale is a written record that ownership of property has transferred from one person to another. It documents who sold what to whom, when, for how much, and in what condition. Think of it as a receipt with legal teeth.

When You Need a Bill of Sale

Motor vehicles. Most states require a bill of sale to transfer vehicle title, register a vehicle, or pay sales tax. Even in states that don’t technically require one, having a bill of sale protects both buyer and seller.

Boats and watercraft. State registration offices typically require a bill of sale for vessel transfers.

Business equipment. Selling office furniture, machinery, restaurant equipment, or technology? A bill of sale documents the transaction and creates a paper trail for tax purposes.

Livestock and horses. The equine and livestock world runs on bills of sale, and breed registries often require them for ownership transfers.

High-value personal property. Jewelry, art, collectibles, musical instruments --- anything valuable enough that you’d want proof of ownership if it were stolen or disputed.

Business asset sales. When selling a business or its assets, a bill of sale documents exactly which assets transferred and at what value.

The general rule: if it’s worth more than a few hundred dollars and you’re transferring ownership, write it down.

What Every Bill of Sale Must Include

1. Identification of the Parties

Full legal names and addresses of both the buyer and seller. Not nicknames. Not “Dave from the gym.” Full names as they appear on government ID.

For businesses, include the legal business name, the name and title of the authorized representative signing on behalf of the business, and the business address.

2. Description of the Property

This is where specificity matters. The description should be detailed enough that there’s no ambiguity about what was sold.

For vehicles:

• Year, make, model, and trim level
• Vehicle Identification Number (VIN) --- this is the most important identifier
• Mileage at the time of sale
• Color (exterior and interior)
• License plate number (current)

For equipment:

• Manufacturer and model
• Serial number (if available)
• Condition description
• Any accessories or components included

For general personal property:

• Detailed physical description
• Any identifying marks, serial numbers, or registration numbers
• Condition (new, used, refurbished, as-is)
• Included accessories or documentation

3. Sale Price and Payment Terms

The total purchase price. How it was paid (cash, check, wire transfer, financing). Whether payment was received in full or if there’s a payment plan.

If there’s a payment plan, the bill of sale should reference a separate promissory note or installment agreement that details the payment schedule, interest rate, and consequences of default. Don’t try to cram complex financing terms into a bill of sale --- use the right document for the job.

For trades or exchanges, describe the property being exchanged and the agreed value of each item.

Important for tax purposes: The sale price on the bill of sale is typically what the buyer pays sales tax on. In some states, if you sell a car to a family member for $1, the DMV will assess sales tax on the fair market value instead of the stated price. Know your state’s rules.

4. Condition and Warranty Disclosures

Most private sales are “as is” --- the seller makes no warranties about the item’s condition, and the buyer accepts it in its current state. This needs to be stated explicitly:

“The property described herein is sold ‘AS IS’ with no warranties, express or implied, including but not limited to warranties of merchantability or fitness for a particular purpose.”

If the seller IS providing a warranty (which is more common in business-to-business sales), describe the warranty terms: what’s covered, for how long, and what the remedy is (repair, replacement, or refund).

For vehicles, many states require sellers to disclose known defects. An “as is” clause doesn’t necessarily override state lemon law protections or fraud claims. If you know the transmission is failing and you don’t disclose it, “as is” won’t protect you.

5. Date of Sale

The exact date the transaction takes place. This establishes when ownership transferred, which matters for:

• Insurance liability (if the car is in an accident an hour after the sale, whose insurance covers it?)
• Registration deadlines (most states give the buyer a window to register a vehicle after purchase)
• Tax reporting (which tax year the sale falls in)
• Warranty start dates

6. Signatures

Both buyer and seller must sign the bill of sale. In some states, signatures must be notarized for vehicle transfers or sales above a certain dollar amount.

Even when notarization isn’t legally required, it adds a layer of authentication that can be valuable if the bill of sale is ever questioned.

State-Specific Requirements for Vehicle Bills of Sale

Vehicle bill of sale requirements are all over the map (pun intended):

States that require a bill of sale for vehicle transfer: Most states, including New York, Pennsylvania, Maryland, Montana, Nebraska, and West Virginia.

States where the title transfer alone is sufficient: Some states (like California and Texas) primarily rely on the title for ownership transfer, but a bill of sale is still recommended for record-keeping and tax purposes.

Notarization requirements: Louisiana, Maryland, Montana, Nebraska, New Hampshire, and West Virginia require notarized bills of sale for vehicle transfers. Others don’t.

Odometer disclosure: Federal law requires an odometer disclosure statement for vehicles less than 25 years old and under 16,001 pounds. Many states include this on the title itself, but some require a separate odometer statement or include it in the bill of sale.

Emissions and safety inspection: Some states require proof of inspection before transfer can be completed.

Sales tax: The buyer typically pays sales tax based on the bill of sale amount when registering the vehicle. Tax rates and exemptions (family transfers, gifts) vary by state.

Common Mistakes That Cause Real Problems

Not keeping a copy. Both buyer and seller should have a signed copy. A seller who can’t prove they sold a vehicle can be held liable for parking tickets, toll violations, or even accidents that happen after the sale.

Vague property descriptions. “One used truck” is not adequate. If there’s a dispute about what was sold, a vague description makes the bill of sale nearly useless. Include VINs, serial numbers, and specific identifying details.

Leaving the date blank. Some people fill out the bill of sale but leave the date for “when we finalize.” Then nobody fills it in. An undated bill of sale creates ambiguity about when ownership transferred.

Not disclosing liens. If there’s an outstanding loan on a vehicle, the seller needs to disclose it and arrange for lien release at or before the sale. Buying a car with an undisclosed lien means the lender can repossess it from you even though you paid the seller in full.

Forgetting about sales tax. Especially in private sales, buyers sometimes forget that they’ll owe sales tax when they register the item. On a $20,000 vehicle in a state with 6% sales tax, that’s $1,200 you might not have budgeted for.

“Gift” sales to avoid taxes. Listing the sale price as $0 or “gift” when money actually changed hands is fraud. States are wise to this and often have minimum value rules or require affidavits for gift transfers.

How to Handle Payment Safely

For high-value sales between strangers:

• Cash works for smaller amounts but creates safety concerns for larger sums. Meet in a public place (many police stations have designated transaction areas).
• Cashier’s check is the traditional method for vehicle sales, but verify it with the issuing bank before handing over the property. Counterfeit cashier’s checks are common in private vehicle sales.
• Wire transfer provides a clear paper trail but ensure the funds have actually arrived (not just “pending”) before completing the sale.
• Escrow services add cost but provide security for both parties on high-value transactions.
• Never accept personal checks for high-value items from strangers. They can bounce days after you’ve handed over the keys.
