Power of attorney as a deal

The power of attorney is an instrument that supports civil rights. It is valid when there is a will and its expression as well as the absence of any circumstances that alter the initial arrangement of the person authorizing the other to act. The law requires the power of attorney to be completely honest with and loyal to the principal in the dealings. The will and the expression of the will must be consistent; the inconsistency means the deal is invalid. Moreover, the effect of the power of attorney ends when, for example, the authorizing person decides to cancel the agreement.
