Relating to the registration as a lobbyist of persons who engage in certain lobbying activities on behalf of a foreign adversary and to prohibitions on the receipt of compensation related to those lobbying activities; providing a civil penalty.

SB 1845 requires lobbyists who communicate directly with Texas lawmakers to influence legislation on behalf of a "foreign adversary" (as defined by U.S. Commerce Department rules, including sanctioned foreign governments or entities) to register with the state. It prohibits such lobbyists from receiving compensation for these activities and imposes civil penalties for violations. The bill directly affects individuals or firms representing foreign governments or entities designated as adversaries under federal law. Key provisions include mandatory registration for lobbying related to foreign adversaries and a ban on accepting payment for those efforts, aiming to increase transparency around foreign influence in Texas policymaking.
