CAUTION. A term of the Roman civil law, which is used in various senses. It signifies, sometimes, security, or security promised. Generally every writing is called cautio, a caution by which any object is provided for. Vicat, ad verb. In the common law a distinction is made between a contract and the security. The contract may be good and the security void. The contract may be divisible, and the security entire and indivisible. 2 Burr, 1082. The securities or cautions judicially required of the defendant, are, judicio sisti, to attend and appear during the pendency of the suit; de rato, to confirm the acts of his attorney or proctor; judicium solvi, to pay the sum adjudged against him.
