Ala. Code § 34-25B-50

(a)(1) A business entity and its agents, officers, and employees, whether domiciled within or outside of this state, which employ or subcontract with private investigators, may not practice, advertise, or hold themselves out to the public as a private investigation agency without first being licensed by the board. A violation of this subsection by an applicant or a licensee shall be punishable as a Class A misdemeanor. (2) This subsection does not prevent a business entity domiciled outside of this state from contracting with a private investigation agency domiciled within this state, but requires any private investigator doing contract work for a business entity domiciled outside of this state, which is not licensed in this state, to register as a private investigation agency. (b) Commencing on January 1, 2024, no business entity that conducts private investigations for compensation in this state, and employs private investigators in this state, may operate without a license.
