This template gives you everything you need for a professional, customizable and legally binding Bill Of Sale Firearm Indiana.
Indiana doesn't require one for private sales between residents. Still smart to have one though. Documentation protects you if ownership gets questioned.
One thing you need is the contact information for both people. Then you should also include the gun's make and model, caliber, serial number, what you paid for it, and when you bought it.
No background checks required for private sales between Indiana residents. Dealer sales still go through federal background check requirements.
