(5) The affidavit may be made before the clerk or deputy clerk of the court in which the garnishment is filed or before any officer authorized to administer oaths, including a notary public, and may be approved by the clerk or deputy clerk if the judge or judges of the court promulgate rules supervising the initiation of the garnishment proceedings and the affidavit is made and approved pursuant to such rules. No court rule or practice shall preclude a plaintiff from proceeding pursuant to paragraph (1), (2), (3), or (4) of this Code section.
