Article 14 of Presidential Instruction Number 1 of 1991 concerning the Compilation of Islamic Law (KHI), states that to carry out a marriage there must be a prospective husband, prospective wife, marriage guardian, two witnesses, consent and acceptance. In Article 19 it is reaffirmed, marriage guardians (wali) in marriage are pillars that must be fulfilled for the prospective bride who acts to marry her off. On that basis, the guardian becomes one of the important requirements and must be present in every marriage event.
