What is the name of your state (only U.S. law)? Armed Froces Pacific
Can I be forced to sign a power of attorney? Can those who attempt to have me sign one be held accountable?
Forced, as in them putting a pen in your hand and manipulating it in order to effect the signing of the POA? Probably not.
That being said, what kind of POA are we talking about, and why are they "forcing" you to try to sign one?
Choices have consequences. It's entirely possible that if you DON'T sign, then those consequences could be held against YOU.
