In law, the making of a false writing with the intent to defraud. Writing need not be handwriting: the law of forgery also covers printing, engraving, and keyboarding. Counterfeiting is usually regarded as a specific type of forgery. Checks, negotiable instruments, contracts, wills, and deeds are examples of documents that may be forged. Evidence may also be forged. Forgery requires fraudulent intent; it is not forgery to sign another's name, fill in blanks, or alter a genuine writing in the honest, though mistaken, belief that such conduct is authorized.
