Demand
An assertion of a right or a claim, calling on another person to do something. In court, a complaint must include a demand for the relief sought (Fed. R. Civ. P. 8(a)(3)); a party may demand a jury trial by serving a written demand and filing it (Fed. R. Civ. P. 38(b)); and a written demand must be served on every party (Fed. R. Civ. P. 5(a)(1)(E)). Outside court, a demand letter asks for payment or performance before a lawsuit, and some claims or statutes require a demand before suit is filed. Under UCC § 3-108(a), a promise or order is payable on demand if it says it is payable on demand or at sight, otherwise indicates it is payable at the will of the holder, or states no time of payment.
