Revocation

The nullification of a person's own act; the extinguishment of a right by the person who created it; the cancellation of an instrument by its maker. As, to revoke an appointment, a power of attorney, a will, the probate of a will, letters testamentary or of administration, a submission to arbitrators or a referee, the power of a partner to act for the firm. "To revoke" is to recall what one has done or promised. By a loose use of language, anything which renders a bequest inoperative at the testator's death may be called a "revocation." The "ademption" of a legacy is not usually called revocation. When ademption is not used, the act is called satisfaction, payment, performance or execution. A revocation is an act done by a testator by which he recalls his will. Consists in the purpose to destroy or annul the operation of the instrument, manifested by some outward sign or symbol. The question is one of fact and intention.
