Gun Bill of Sale: Template & State Rules

Selling or buying a firearm privately? A gun bill of sale is the simple paper trail that records who sold what to whom, and when. It is short to fill out but genuinely worth doing — it protects the seller after the firearm leaves their hands and gives the buyer proof of how they came to own it. This guide explains what a firearm bill of sale is, when one is required, exactly what to include, the background-check basics behind private gun sales, and how to create one for free.

What Is a Gun Bill of Sale?

A gun bill of sale is a written record of a private firearm sale from one party to another. It identifies the seller and the buyer, describes the firearm (make, model, caliber or gauge, and serial number), states the price and the date, and is signed by both people. In plain terms, it is the receipt for the transaction.

That receipt does more work than it looks like. For the seller, a firearm bill of sale is evidence that they no longer owned the gun after a specific date — which matters a great deal if the firearm is ever lost, stolen, or misused once it is out of their possession. For the buyer, it documents a legitimate chain of ownership. Unlike a car, a firearm usually has no title or registration in most states, so this one document is often the only paper record that the sale ever happened.

A gun bill of sale is not a permit, a license, or a substitute for any background check your state requires. It records the transaction; it does not by itself make the transaction legal. Whether a private sale is even permitted, and what steps it must follow, is governed by the law where you live.

Is a Bill of Sale Required to Sell a Gun?

There is no single national rule, and this is the part people most often get wrong. Requirements fall into a few broad groups, and the honest answer for almost everyone is: it depends on your state, and you should check before you sell.

States with no statewide requirement

In many states there is no law requiring a written bill of sale for a private firearm sale, and no statewide registration of ordinary firearms. In these states a bill of sale is optional but still smart — it is the only record that protects you, so most people use one anyway.

States that regulate private transfers more tightly

A number of states regulate private (non-dealer) firearm transfers more closely. Depending on the state, that can mean the transfer must go through a licensed dealer, that a background check is required even for a private sale, that handguns are treated differently from long guns, or that a record of the transfer must be kept or reported. In these states a documented transfer is not just good practice — part of the process may be required by law.

The honest bottom line on requirements

Because the rules differ so much from one state to the next — and sometimes from one city or county to the next — never assume your state works the way a neighboring state does. Before any private firearm sale, look up your current state and local requirements (a search for "[your state] private firearm sale law" is a good start) or ask a licensed dealer. Our bill of sale requirements by state guide and do I need a bill of sale guide cover the document side of the question in more detail.

What to Include in a Gun Bill of Sale

A complete firearm bill of sale should capture the following. The more specific you are, the stronger your protection if the sale is ever questioned — and the serial number is the field you cannot afford to get wrong.

Firearm details

• Make and model: e.g., "Smith & Wesson M&P Shield." Record exactly what is stamped on the firearm.
• Caliber or gauge: e.g., "9mm" or "12 gauge."
• Serial number: Copy it letter-for-letter from the firearm itself. This is the single most important field — it is how the specific firearm is identified, and an inaccurate serial number undermines the whole document.
• Firearm type: Handgun, rifle, shotgun, or other.
• Barrel length and any other identifying detail, where relevant.
• Condition: New, like new, good, fair, or poor.

Buyer and seller information

• Full legal names of both parties (matching government-issued ID)
• Current addresses
• Phone numbers, if you want them on record
• Many sellers also note the buyer's ID type and number, so there is a record of who they sold to

Sale terms

• Sale price (or "gift" with $0 if no money changes hands)
• Date of the sale
• Payment method — cash, cashier's check, or bank transfer
• As-is clause: Most private firearm sales are "as-is, no warranty." Spelling this out protects the seller from later claims about function or condition — though it never excuses hiding a known defect.
• Signatures of both parties (and a notary or witness line if your state requires one)

Make two copies, signed in ink — one for each party. Keep yours somewhere safe for several years. If you are not sure how to fill in each field, our how to write a bill of sale guide walks through the structure with examples that apply to a firearm sale too.

Private Sales & Background-Check Basics

This is the area where the law is most likely to apply to your sale, so it is worth understanding the basics — while remembering that the details depend on your state and that this is general information, not legal advice.

At the federal level, the key distinction is between licensed dealers and private sellers. A licensed dealer (often called an FFL, for Federal Firearms License) is required to run a background check on a buyer before completing a sale. A private individual selling their own firearm is treated differently under federal law. That gap — the difference between a dealer sale and a private sale — is exactly the space that many state laws step in to fill.

Some states require all firearm transfers, including private ones, to go through a licensed dealer or to include a background check. Others require it for handguns but not long guns, and others have no such requirement at all. A few states also restrict who can buy or possess a firearm based on factors set in law. Because these rules vary so widely, the safe approach for a private seller is straightforward:

• Confirm whether your state requires a background check or dealer involvement for a private sale before you agree to anything.
• When in doubt, route the transfer through a licensed dealer — they handle the check and the paperwork correctly.
• Never sell to someone you know or suspect is prohibited from owning a firearm.
• For an out-of-state buyer, expect that the transfer will generally need to go through a licensed dealer in the buyer's state. Interstate private transfers are tightly restricted under federal law.

A bill of sale and a background check are not the same thing and do not replace each other. The bill of sale records the transaction; the background check (where required) is a separate legal step. Doing one does not satisfy the other.

Closing a Private Gun Sale Safely

Beyond the paperwork, a few habits make a private firearm sale go smoothly and keep both parties protected:

• Verify the buyer's ID and eligibility. Confirm who you are selling to, and do not sell to anyone you believe is prohibited from owning a firearm.
• Record the serial number exactly. Photograph it if you can, and double-check it against the bill of sale before signing.
• Use a traceable payment. A cashier's check or bank transfer leaves a record; if you take cash, note it on the bill of sale.
• Meet safely. Many sellers prefer to meet at, or route the transfer through, a licensed dealer — which also handles any required background check in one stop.
• Keep your copy. Store the signed bill of sale for several years as proof of when ownership transferred.

The Bottom Line

A gun bill of sale is short, but it carries real weight. Record the make, model, caliber, and — above all — the serial number exactly; capture both parties' names and the price and date; add an as-is clause; and have both people sign. Then check your own state and local rules on private sales and background checks before you complete the transaction, and use a licensed dealer whenever the law requires it or an out-of-state buyer is involved. Do that, and the sale is documented, defensible, and done right.
