Any process or notice may be executed on or before the return day thereof. If it appear to be duly served and good in other respects, it shall be deemed valid, although not directed to any officer, or although directed to an officer who is not qualified to execute it, provided it be executed by any other to whom it might lawfully have been directed. In any case in which it would be improper for the sheriff to execute any process, notice, writ or order, or summon a jury, because of interest or other disability, it shall be lawful for any deputy sheriff of such county not similarly disqualified to execute such process, notice, writ or order, or summon such jury, and make return thereof in his own name as deputy sheriff, and the execution and return thereof, if in other respects duly made, shall be valid, though it be directed to the sheriff. Process or notice to commence actions or suits, including writs of scire facias, mandamus, quo warranto, certiorari, prohibition, and alias or other process where the original is returned not executed, may also be served by any credible person; and the return of such person, verified by his affidavit, shall be evidence of the manner and time of service.
