What is the difference between a will and a power of attorney?

A power of attorney operates while you are alive and ends at death. A will operates only after death. They cover opposite periods and cannot substitute for each other.

A power of attorney operates while you are alive and ends at death. A will operates only after death. They cover opposite periods and cannot substitute for each other.

The Canadian position

Ontario distinguishes a continuing power of attorney for property from one for personal care. Acting under a POA after death is a common and serious error.

The Islamic position

A POA corresponds to wakalah, an agency that likewise lapses on death, at which point the wasi's authority begins.

Across the madhahib

The four Sunni schools are not recorded as differing materially on this point in the sources reviewed. Where your own case turns on it, put it to a scholar of your school.

Before you act on this

General information, not legal or religious advice. Inheritance depends entirely on the exact family circumstances. Confirm the Canadian position with a lawyer in your province and any religious ruling with a qualified scholar.
