Current with changes from the 2024 legislative session effective on or before 7/1/2024, from Acts 2,3, 6-535, and 580-647
In any case where service on a foreign corporation may be made through the secretary of state, under any law heretofore or hereafter enacted, such service may be made in person on the secretary of state anywhere in the state. Should the secretary of state be absent from his office, service may be made on the assistant secretary of state, or on some other individual in the office of the secretary of state designated by the latter to receive service of process in his absence, and such service has the same effect as if made upon the secretary of state personally.
