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 dealers if a buyer is prohibited from purchasing a firearm. Individuals aged 18 and older can apply for placement or removal from the list, either directly to the KBI or through a healthcare provider, who must verify the individual's identity before submitting the request. The KBI is required to keep all information related to the list confidential, with exceptions for law enforcement and the individuals themselves.

The bill also 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. Licensed firearm dealers are prohibited from transferring firearms to individuals on the list. Violations of the act can result in civil penalties or community service, but individuals who are on the list are exempt from penalties related to their own requests or placements. The provisions of the act are set to expire on July 1, 2030, unless renewed by the legislature.
