How is it different from a general power of attorney?
Scope, and therefore exposure. A general POA gives broad authority across your affairs; a special POA gives one authority for one purpose. If the job is to sell a single car, a special POA that names that car is the correct instrument.
The narrower document is also the easier one to get accepted, because a receiving authority can see on its face that the act being attempted is the act authorised.
- General POA: broad authority, usually until revoked
- Special POA: one act, ending when that act is done
- A narrow document is harder to misuse
- Receiving authorities question narrow documents less often
