Wasi is the executor of a wasiyyah, and classically guardian of minors.
The Canadian position
Maps onto two separate Canadian appointments: estate trustee for property, guardian for children.
Canadian law gives effect to whatever a valid will says, so an Islamic concept takes effect here through the drafting rather than automatically.
The Islamic position
The role is an amanah — held in trust and answerable to the heirs.
Confirm the position for your own family and school with a qualified scholar rather than relying on a general summary.
All four schools want the same qualities in a wasi — adulthood and legal capacity, Islam, integrity and the ability to do the job. They differ on what failing one of them does. Three schools treat them as conditions of validity, so an appointment that fails one is void. The Hanafi school treats the appointment as valid and puts the remedy in the judge’s hands.
