SERGEANTY (Serjeantia), signifies, in law, a service that cannot be due by a tenant to any lord but the king; and this is either grand serjeanty, or petit. The first is a tenure by which the one holds his lands of the king by such services as he ought to do in person to the king at his coronation; and may also concern matters military, or services of honour in peace; as to be the king's butler, carver, &c. Petit serjeanty is where a man holds lands of the king to furnish him yearly with some small thing towards his wars; and in effect payable as rent. Though all tenures are turned into scutage by the 12 Car. II. cap. 24; yet the honorary services of grand serjeanty still remain, being therein excepted. See KNIGHT-SERVICE.
