The Kansas Voluntary Do-Not-Sell Firearms List Act establishes a system for individuals to voluntarily register to be placed on a list that prevents them from purchasing firearms. The Kansas Bureau of Investigation (KBI) is tasked with creating and maintaining this list, which will be used to inform licensed firearm dealers if a buyer is prohibited from purchasing a firearm. Individuals aged 18 and older can apply to be added to or removed from the list, either directly or through a healthcare provider, who must verify the individual's identity before submitting the request to the KBI. The act also includes provisions for the confidentiality of the information on the list, allowing disclosure only to law enforcement or the individual themselves.

The bill outlines several unlawful actions related to the list, including inquiring about someone's status on the list for unauthorized purposes, providing false information to manipulate someone's status, and discriminating against individuals based on their inclusion on the list. Additionally, it prohibits licensed dealers from transferring firearms to individuals on the list. Violations of the act can result in civil penalties or community service. The provisions of the act are set to expire on July 1, 2030, unless reviewed and renewed by the legislature before that date.
