Black's Law Dictionary
The chirography of a person; the cast or form of writing peculiar to a person, including the site, shape, and style of letters, tricks of penmanship, and whatever gives individuality to his writing, distinguishing it from that of other persons.
In re Hyland's Wlll (Surr. Ct.) 27 N. Y. Supp. 963.
Anything written by hand; an instrument written by the hand of a person, or a specimen of his writing. Handwriting, considered under the law of evidence, includes not only the ordinary writing of one able to write, but also writing done in a disguised hand, or in cipher, and a mark made by one able or unable to write.
