HB 4418 expands the enforcement authority of county and district attorneys in cases involving human trafficking awareness and prevention at commercial lodging establishments. The bill amends the Business & Commerce Code to allow county and district attorneys to issue written notices to lodging operators suspected of violating human trafficking prevention laws, specifying the violation and potential civil penalties. It also grants these attorneys the authority to initiate civil actions for penalties and injunctive relief to ensure compliance. Civil penalties recovered by county or district attorneys will be allocated to the county where the violation occurred.
