Firearms and Ammunition - As introduced, enacts the "Tennessee Voluntary Do Not Sell Firearms Act," which permits a person to voluntarily waive their firearm rights through filing a waiver with the clerk of the circuit court in the county of the person's residence; specifies procedures the clerk, TBI, and department of safety must follow upon receipt of a waiver. - Amends TCA Title 4, Chapter 3; Section 10-7-504 and Title 39, Chapter 17, Part 13.

SB 642 creates the "Tennessee Voluntary Do Not Sell Firearms Act," allowing Tennesseans to voluntarily restrict their own firearm access by filing a waiver with their county circuit court clerk. The waiver, verified with government-issued ID, prohibits firearm purchases and requires the Tennessee Bureau of Investigation (TBI) to enter it into background check systems within 24 hours, effectively blocking firearm transactions. Individuals can revoke the waiver after seven days, and the TBI removes their name from background systems 21 days later, reinstating handgun carry permits if applicable. This process is confidential, with false statements on waiver forms punishable as perjury.
