Selling or buying a firearm through a private transaction? In most states, there's no legal requirement to involve a dealer — but that doesn't mean you should skip the paperwork. A proper bill of sale protects both buyer and seller.
Why You Need a Bill of Sale
A bill of sale serves several critical purposes:
- Proof of legal transfer — Documents that the firearm changed hands voluntarily and lawfully
- Liability protection — If the firearm is later used in a crime, the seller has proof they no longer possessed it
- Ownership verification — The buyer can prove they legally acquired the firearm
- Financial record — Establishes the purchase price for insurance and tax purposes
- Serial number documentation — Creates a paper trail for the specific firearm
A bill of sale is not a substitute for a background check where required by law. Always comply with your state and local regulations.
What to Include

Seller Information

State-by-State Considerations
Firearm transfer laws vary significantly by state. Some key variations:
| Requirement | States That Require It |
|---|---|
| Universal background check for private sales | CA, CO, CT, DE, DC, HI, IL, MD, MA, NV, NJ, NM, NY, OR, PA, RI, VT, VA, WA |
| Bill of sale required by law | Very few — but always recommended |
| Must go through FFL dealer | Several states for handguns |
| Waiting period applies | Varies |
| Permit required to purchase | CT, HI, IL, IA, MA, MD, MI, MN, NE, NJ, NY, NC |
Always check your state and local laws before completing a private transfer. This article is informational, not legal advice.
Common Mistakes to Avoid
1. No Serial Number Verification
Always physically verify the serial number on the firearm matches what's written on the bill of sale. Don't take the seller's word for it.
2. Incomplete Buyer/Seller Information
Vague information defeats the purpose. "John from the gun show" isn't going to hold up if you need to prove a transfer happened.
3. No Copies
Both parties should keep a copy. This seems obvious, but many people hand over the only copy or forget to make one.
4. Selling to a Prohibited Person
If you have any reason to believe the buyer is prohibited from possessing firearms — they're a felon, under indictment, subject to a restraining order, etc. — do not complete the sale. A bill of sale doesn't protect you if you knowingly sell to a prohibited person.
5. Skipping the Bill of Sale Entirely
"We've been friends for 20 years, we don't need paperwork." Yes, you do. Friendships change. Memories fade. Paperwork is forever.

- Searchable — Find any transaction instantly by date, buyer, or firearm
- Backed up — Survives physical disasters
