Power of Attorney enables an agent to act in the principal's name and signature with full legal effect. Power of Attorney is the instrument by which a donor authorises a donee to act as the donor's agent and in the donor's stead. Section 2 of the Power of Attorney Act, 1882 provides that the donee may do acts in his own name and with his own signature by authority of the donor, and that such acts are effectual in law as if done by the donor in the donor's name and with the donor's signature.
