- The guardian is a prerequisite for the validity of marriage. If the marriage occurs without a guardian or a woman marries herself off, the marriage is not valid.
- The guardian is the closest man to a woman. No distant guardian can marry her off while a closer guardian is available.
- A guardian must be: accountable, male, wise, aware of the interests related to marriage, and have the same religion as the one under his guardianship. Whoever does not fulfill these requirements is not qualified to be a guardian in a marriage contract.
