A firearm bill of sale documents a private firearm transfer: who sold what to whom, for how much, on what date, and with signed certifications that the buyer may lawfully possess a firearm. For the seller, it is permanent proof that the firearm left their hands on a specific date; for the buyer, it is proof of lawful acquisition and ownership.
One thing this document is not: a substitute for the legal transfer process. Firearm transfers are governed by federal law and by the law of your state, and a growing number of states require every private sale to go through a licensed dealer with a background check. The paperwork records the deal; the law decides how the firearm may change hands.
Why sellers should never skip the paperwork
Firearms are serialized and traceable. If a firearm you once owned is recovered at a crime scene, the federal trace will lead to the last recorded transfer, and without a bill of sale that may be you. A signed record showing the firearm was sold to a named, identified buyer on a specific date is the seller's answer to that knock on the door, which is why experienced sellers keep firearm bills of sale permanently, not just for a few years.
- Proof for the seller that the firearm was transferred on a given date, to a named buyer who certified being eligible
- Proof for the buyer of lawful acquisition, useful for insurance, resale, and any later questions about origin
- A written record of the serial number, which both parties need if the firearm is ever lost or stolen
- Documentation of the price actually paid
The legal transfer process comes first
Federal law prohibits transferring a firearm to anyone you know or have reasonable cause to believe is a prohibited person, and it generally restricts direct transfers between unlicensed residents of different states, which normally must route through a licensed dealer. On top of that federal floor, states add their own rules: universal background check states require nearly all private transfers to be completed by an FFL, some states require purchase permits or firearm safety certificates, and some register certain firearms. These rules change and vary widely, so verify the current requirements of the state where the transfer takes place before money or the firearm changes hands.
When in doubt, use a licensed dealer
Any gun shop can run a private transfer for a modest fee: the dealer checks the buyer through the federal background check system and keeps the required transfer record. It is the safest route for both parties, and in many states it is the only lawful one for a private sale.
This template does not verify eligibility
The certifications in this document record what each party affirms; they do not verify anything. Only the background check process confirms that a buyer is not prohibited. Completing this form does not make an otherwise unlawful transfer lawful, and it is not legal advice about whether your transfer is permitted.
Where the federal rules live
Two sources define the federal floor for every private transfer. The Gun Control Act's implementing regulations at 27 CFR part 478 set the rules on licensed dealers, interstate transfers, prohibited persons, and the 2022 expansion of who counts as "engaged in the business" of dealing firearms, which can require frequent private sellers to obtain a license. The ATF's firearms resources publish the current forms, state law summaries, and guidance on private sales. Sellers who move more than the occasional personal firearm should read the engaged-in-the-business criteria carefully: selling for profit on a repetitive basis without a license is a federal offense, no matter how good the paperwork is.
State law then layers on top, and the spread is wide: universal background check states route nearly every private transfer through a dealer; permit-to-purchase states require the buyer to hold a current permit the seller should photocopy; a few states impose waiting periods or register handguns; and the remaining states allow direct private sales between residents who are not prohibited. The transfer-method clause in this template exists precisely because the same two people, with the same firearm, face different legal processes depending on which state line they are standing behind.
Filling out the form, step by step
- Identify both parties with full legal names and current addresses; sellers commonly also record the number of the buyer's government-issued photo ID on their copy
- Describe the firearm exactly as marked: manufacturer, model, caliber or gauge, and the serial number copied character by character from the frame or receiver
- List included accessories such as magazines, cases, or optics, so there is no dispute about what the price covered
- State the price, the payment method, and the date of sale
- Select how the transfer is completed: through an FFL with a background check, or directly where state law allows it
- Read the certifications, sign in each other's presence, and each keep a signed copy permanently
If anything about the buyer gives the seller pause, the seller should walk away or insist on an FFL transfer. The certification clause exists to make both parties confront the eligibility question in writing before the firearm changes hands.
Frequently asked questions
Is a bill of sale enough to legally transfer a firearm?
Not by itself. The bill of sale documents the sale; the transfer must separately comply with federal law and the law of the state where it happens, which may require a background check through a licensed dealer, a permit, a waiting period, or registration. Check your state's current rules before completing the sale.
Do private gun sales require a background check?
It depends on the state. Federal law requires background checks for dealer sales, and a substantial number of states extend that requirement to private transfers, which must then be completed through an FFL. In the remaining states, a direct private sale between residents may be lawful, but it is never lawful to transfer to someone you know or have reason to believe is prohibited.
Can I sell a firearm to someone from another state?
Generally not directly. Federal law requires most interstate transfers between unlicensed persons to go through a licensed dealer in the buyer's state, where the buyer completes the background check. Handguns are the strictest case; consult a dealer before attempting any interstate transfer.
How long should I keep a firearm bill of sale?
Permanently. Firearms circulate for decades, and a trace can arrive many years after you sold one. The bill of sale is the document that shows the firearm left your possession, so store it with your permanent records rather than discarding it after a few years.
Does a firearm bill of sale need to be notarized?
No law requires it for a private sale record, but notarization strengthens the document because it verifies who signed and when. Given how long this record may matter, many sellers choose to notarize it or at least have the parties sign in each other's presence with ID checked.
Can I gift a firearm to a family member with this form?
A genuine gift to an eligible family member in the same state is lawful under federal law and in many states, and this form can record it with a zero or nominal price. Several states exempt close-family transfers from their background check requirements, but not all do; check your state before handing the firearm over.
What is a straw purchase and why does the form mention it?
Buying a firearm on behalf of someone else who is the true recipient is a federal felony, even if that person could have bought it themselves. The buyer certification in this template includes an affirmation that the buyer acts for themselves precisely to put that question in writing.
How do I sell many firearms, for example an inherited collection?
Occasional sales from a personal or inherited collection are generally permitted, but repetitive buying and selling for profit can make you a dealer who needs a federal license. For a large collection, consider consigning through a licensed dealer or auction house, which also handles every background check.
Should the seller photocopy the buyer's ID?
Where state law allows it, recording the ID number or keeping a copy alongside the bill of sale strengthens the seller's record. At minimum, verify that the ID matches the name and in-state address written on the form.
Does this form work for antique or black-powder firearms?
Firearms made in or before 1898 and many muzzleloaders are exempt from the federal Gun Control Act's transfer rules, though some states regulate them anyway. The form works as a sale record either way; the transfer-process rules are simply lighter for true antiques.
