(a) Notices of the requirement of the attendance of jury service in the Circuit Court of Chilton County may be served by first class mail, or may be served as provided by Section 12-17-73. If, in the discretion of the sheriff, the service is made by first class mail, such service shall be made as follows: It shall be the duty of the sheriff to enclose the summons in an envelope addressed to the person to be served and place all necessary postage and a return address thereon with notice to the postal authorities not to forward outside of the county. In the event said jury summons is returned to the sheriff by the United States Postal Service without delivery, the summons shall be made by the sheriff returned NOT FOUND. All jury summons not returned by the United States Postal Service shall be considered for all purposes as sufficient personal and legal service. The provisions of this section in reference to service by mail, however, shall not apply to jury summons returnable before the court instanter, but such summons shall be served only as provided by Section 12-17-73.

(b) Subpoenas requiring the attendance of witnesses in any civil, criminal, equity, or other case or proceeding in the county, or before the grand jury of the county may be served by the sheriff or constable personally or by leaving a copy thereof at the place of residence of the witness, or the sheriff may serve the same by placing a copy thereof in the United States mail, enclosing the subpoena in an envelope properly stamped and addressed to the person or witness to be served. Upon service by the sheriff upon any witness or person by any one of the foregoing methods, the sheriff shall immediately mark the process executed. If the subpoena so mailed is not delivered to the addressee but is returned to the sheriff by the United States Postal Service, then the sheriff shall immediately make a diligent effort to serve the subpoena either personally or by leaving a copy thereof at the place of residence of the witness.

(c) Anything to the contrary notwithstanding in subsection (b), any judge having jurisdiction of the proceeding or case may, on motion of any party or on the court's own motion, order any particular subpoena or the subpoenas in any case or proceeding to be served personally or by leaving a copy thereof at the place of residence of the witness or person or by United States registered or certified mail.
