Key takeaways
- Durable POAs remain effective if the principal becomes incapacitated.
- Springing POAs only take effect upon a defined event (typically certified incapacity).
- Medical POAs (healthcare proxies) handle health decisions; financial POAs handle money matters — most households need both.
- A POA ends at the principal's death — from that point, executors and trustees take over.
How Olomon thinks about this
Olomon stores the executed POA alongside the assets it can affect and lets you see, at a glance, who has authority for what. If a POA is updated or revoked, the record is updated in one place — not scattered across institutions.
In-depth definition
POAs are among the most powerful documents in personal finance: a properly drafted financial POA can move money, sign tax returns, manage real estate, and execute investment decisions. Choose your agent with the same care you'd choose a successor trustee or executor — and revisit the choice when relationships change.
Frequently asked questions
Yes — as long as you have legal capacity, you can revoke a POA in writing at any time. Best practice is to notify the agent and any institution that has been relying on the original POA.
