Washington State’s strict private transfer protocols make a dedicated Washington Firearm Bill of Sale a mandatory part of a responsible owner's files. While state law generally requires transfers to go through a licensed dealer, this document serves as your personal legal receipt for the transaction. For 2026, recording the firearm’s identifiers alongside the buyer’s signature is the only way to ensure your personal records are complete and that you are protected from future liability if the weapon is ever recovered at a crime scene.
