Chirograph

Chirograph, an instrument of gift or conveyance attested by the subscriptions and crosses of the witnesses. Anciently the chirograph was engrossed twice on one piece of parchment, contrariwise, leaving a space between in which was written in large words "Chirograph," and then the parchment was cut in two through the middle of the word, and a part given to each party. The first use of chirographs was in Henry III.'s time.
