How to sell a firearm in Connecticut

A firearm bill of sale records a private gun sale: the make, model, caliber and serial number, the price, the date, and a statement from each party that the sale is legal where it is taking place. It is the seller's proof that the firearm left their possession on a specific date.

Seller steps

  1. Confirm you hold clear ownership. If a lender is on the title, get the lien release before you list it.
  2. Agree on the price and fill in the Connecticut firearm bill of sale above with the buyer. Record the serial number.
  3. Both parties sign and each keeps a copy. Connecticut does not require a notary.
  4. Check Connecticut's private-sale rules. If the state requires a background check or a licensed-dealer transfer, complete that step before the firearm changes hands.
  5. Hand over the firearm and keep your signed copy of the bill of sale for your records.

Buyer steps

  1. Check the description against the firearm itself before you sign.
  2. Keep the signed bill of sale with your records; it is your proof of ownership and purchase price.
  3. If you bought it for a business, give the bill of sale to your bookkeeper for the asset record.

Before you sign

  • Copy the serial number exactly; letters and numbers like O/0 and I/1 cause problems.
  • Check your state's private-sale rules first. Several states require a background check through a licensed dealer for private sales.
  • Record a government ID number for the buyer only if your state requires it; otherwise ID type and state is enough.
  • Both parties sign and keep a copy.

Why a bill of sale matters for a firearm

  • Proves the date the firearm changed hands if it later turns up somewhere it should not.
  • Records the serial number so the buyer can show lawful ownership.
  • Includes a buyer eligibility statement, which many sellers insist on.
  • Some states require private sales to go through a licensed dealer; the bill of sale travels with that paperwork.

Want both parties to walk away with a signed copy and a notary page ready? The $9 ready-to-sign pack adds them.
