Why power of attorney matters

It can support continuity during absence or incapacity, while creating serious authority, abuse, and oversight risks.

How it is applied

The document defines scope, effective date, durability, agents, successors, gifting powers, reporting, revocation, and jurisdiction.

Portfolio example

An agent pays bills and manages accounts after the principal becomes unable to act, where a durable power permits it.

How to interpret it

Authority comes from the document and law, not family relationship alone.

Limitations and common misconceptions

Institutions may require review, agents can abuse power, and documents may be invalid across borders. Legal advice is essential.
