Firearm Bill of Sale Template & Guide

Selling or buying a firearm privately is one of the few transactions where a simple piece of paper can carry real legal weight. A firearm bill of sale, sometimes called a gun bill of sale, records who sold what to whom, when, and for how much. It is your proof that ownership and responsibility for a specific firearm passed from one person to another on a specific date.

This guide explains what a firearm bill of sale is, what every gun bill of sale should include, how to handle the legal side of a private transfer, and the mistakes that can turn a routine sale into a serious problem.

This article is general information, not legal advice. Firearm laws vary widely by state and change often. Always confirm your state and local requirements, and when in doubt, route the transfer through a licensed dealer.

What is a firearm bill of sale?

A firearm bill of sale is a written record of the sale of a gun between a buyer and a seller. It documents the firearm's identifying details, the price, the date, and the terms of the sale, and it is signed by both parties.

Unlike a vehicle, most firearms do not have a government-issued "title." That makes the bill of sale even more important: it is often the only document proving the chain of ownership. If the firearm is later lost, stolen, or recovered at a crime scene, your signed bill of sale shows that it left your hands on a particular date and is no longer your responsibility.

A bill of sale serves three core purposes:

• Proof of transfer: it shows the gun changed hands and when.
• Proof of price: useful for the buyer's records and any applicable tax.
• Limitation of liability: it marks the point at which responsibility shifted to the buyer.

Is a gun bill of sale legally required?

There is no single national answer. Requirements fall into a few categories:

• States that require a background check on private sales. A growing number of states require nearly all firearm transfers, including private, person-to-person sales, to go through a licensed dealer (an FFL) who runs a federal background check. In these states, the dealer typically handles the paperwork.
• States that require or recommend a record of transfer. Some states ask private sellers to keep or file a record of the sale.
• States with no recording requirement. In many states, private sales between residents are not separately regulated, and no document is legally mandated.

Even where a bill of sale is not required, creating one is simply good practice. The cost is a few minutes of paperwork; the downside of having no record can be substantial.

A few federal rules apply everywhere:

• You generally may sell a firearm only to a resident of your own state unless the transfer goes through an FFL.
• You may never knowingly sell to a prohibited person (more on that below).
• Selling firearms as a repeated business for profit requires a federal license; this guide is about genuine private, occasional sales.

What to include in a firearm bill of sale

A complete gun bill of sale should capture the parties, the firearm, the money, and the terms. Include the following:

1. The parties

• Full legal names of the buyer and seller
• Current mailing addresses
• Government-issued ID type and number for each (e.g., driver's license)
• The state of residence of both parties

2. The firearm details

This is the heart of the document. Record, exactly as printed on the gun:

• Manufacturer / make (e.g., Smith & Wesson, Ruger, Glock)
• Model
• Type (pistol, revolver, rifle, shotgun)
• Caliber or gauge
• Serial number (copy this character-for-character)
• Any accessories included in the sale (case, optics, magazines)

3. The financial terms

• The purchase price in numbers and words
• The form of payment (cash, cashier's check, etc.)
• Whether the price was paid in full or in installments

4. The sale terms

• The date of the sale
• An "as-is" clause stating the firearm is sold in its current condition with no warranties
• The buyer's attestation that they are legally permitted to own a firearm and are not a prohibited person
• A statement that the buyer is a resident of the required state (if applicable)

5. Signatures

• Signatures of both buyer and seller
• Date of each signature
• Space for a notary or witness if you choose to use one

How to write a gun bill of sale: step by step

Follow these steps to produce a clean, defensible document.

1. Confirm the buyer's eligibility. Before anything else, satisfy yourself that the buyer can legally own a firearm. The safest path is to meet at a licensed dealer and let them run a background check.
2. Verify identity. Check a government-issued photo ID and confirm the buyer is a resident of the appropriate state.
3. Record the firearm details. Read the make, model, caliber, and serial number directly off the gun, never from memory.
4. State the price and payment terms. Write the amount in both numerals and words to prevent later disputes.
5. Add the as-is and attestation language. Make clear there are no warranties and that the buyer affirms they are legally allowed to possess the firearm.
6. Sign and date together. Both parties sign in each other's presence (or before a notary).
7. Make two copies. Each party keeps a signed original. Store yours somewhere safe and lasting.

Handling the legal side of a private transfer

The paperwork is only part of the job. The transfer itself has to be legal.

Go through a licensed dealer when in doubt

Routing the sale through an FFL is the single best way to protect yourself. The dealer runs the background check, confirms eligibility, and creates a federal record of the transfer. In many states this is mandatory; everywhere else it is a smart, low-cost insurance policy.

Know who counts as a prohibited person

Federal law bars certain people from possessing firearms, including convicted felons, people subject to qualifying domestic-violence restraining orders, those with certain disqualifying convictions, unlawful drug users, and others. Knowingly transferring a firearm to a prohibited person is a federal crime. If anything about the buyer gives you pause, stop the sale.

Don't sell across state lines on your own

With narrow exceptions, a private seller may only transfer a firearm to a resident of the same state. Interstate transfers must generally go through an FFL in the buyer's state. This is similar in spirit to how other private sales are documented, see our overview of whether you need a bill of sale when selling a vehicle, but the firearm rules are stricter.

Think about liability

Because a firearm can cause harm, the moment of transfer matters. A signed, dated bill of sale establishes when responsibility shifted to the buyer. For high-value or higher-risk transactions, some sellers pair the bill of sale with a hold-harmless agreement to further document that the buyer assumes responsibility going forward.

Common mistakes to avoid

Even careful sellers slip up. Watch for these:

• Skipping the serial number. Without it, the document doesn't actually identify which firearm was sold. This is the most common and most damaging omission.
• Not verifying the buyer. Failing to check ID, or ignoring red flags about eligibility, exposes you to criminal liability, not just a bad deal.
• Assuming federal law is the whole story. State and local rules are often stricter. Always check yours.
• Leaving out as-is language. Without it, a buyer may later claim you warranted the firearm's condition.
• No buyer attestation. A short statement that the buyer is legally allowed to own the firearm strengthens the document and your defense if questions arise later.
• Only one copy. If the single copy is lost, neither party has proof. Always make two.
• Handling payment carelessly. For installment sales, document the terms clearly, much like you would in a promissory note for a personal loan, so there's no confusion about what's owed.
• Treating a bill of sale like a registration. It records the sale; it does not, by itself, satisfy any state registration or background-check requirement.

Firearm bill of sale vs. other transfer documents

A bill of sale is sometimes confused with other paperwork:

• Background check / FFL transfer record. This is the eligibility step. It confirms the buyer can own the gun; the bill of sale records the transaction. They serve different purposes and, where checks are required, you need both.
• Registration. Some states maintain firearm registries; most do not. A bill of sale is not a substitute for any required registration.
• Title. Firearms generally have no title, which is exactly why the bill of sale carries so much weight as the proof of ownership.

The pattern is the same one you'll see across private-sale documents, for instance, a motorcycle bill of sale records the deal while the DMV title handles ownership. For firearms, the bill of sale and the background-check step do that combined job.
