joint power of attorney - what if one gets incapcitated?

[voltaire]

I have a question regarding joint power of attorney.

Person gives power of attorney to two people, let say A & B (acting jointly).
However, "A" becomes incapacitated and cannot perform the power of attorney duties.
Does "B" become the sole power of attorney by default?

What if "A" itself has power of attorney, let say "C". Does "B" now jointly power of attorney with "C"?

Please do not ignore the "What is your state?" question. Responses often depend upon the applicable state.

A well-written POA document should contain provisions specifying what happens if one or more of the agents/attorneys-in-fact chooses not to or can't continue to exercise the power granted. Did this one?

What if "A" itself has power of attorney, let say "C". Does "B" now jointly power of attorney with "C"?

I know of no state that would permit such "pyramiding."

In the absence of any clause as anteater recommends, the power of attorney is not usable unless both joint parties are acting. It matters not why one is not able to act.
