[001] and military services, and also homage,1 and thus need not be set forth in charters, [002] for if homage has been done and it is royal service it follows therefrom that relief [003] or wardship and marriage will belong to the chief lord, whether the military [004] service or the serjeanty connected with the host2 is great or small, if only to the [005] extent of a single halfpenny.3 There are some customs which are called neither [006] services nor the concomitants of services, as reasonable aids for making [the lord's] [007] eldest son a knight or marrying his eldest daughter, aids that are furnished, of [008] favour not of right, because of the need and indigence of the chief lord. For an aid [009] is never exacted unless necessity requires it, nor is anyone bound to furnish it [010] except because of the need of his chief lord and because he is his free man. These [011] aids are not praedial but personal, for they look to persons not fees,4 as may be [012] drawn from the command of the lord king by his writ, which is in this form: that [013] the sheriff rightfully and without delay cause such a one to have of his knights [014] and free tenants in his bailiwick a reasonable aid for making his eldest son a knight [015] (or for marrying his eldest daughter) as will be explained below.5 And since these [016] aids depend on the favour of tenants and not the will of lords, and are not feudal [017] but personal, regard ought to be had to the person of each, of the lord and the [018] tenant, that the lord's need, whether great or small, be relieved and the tenant [019] suffer no hardship, the aid being to the advantage of the donee and the honour of [020] the donor.6 There are also, among others, some personal payments not called [021] services, as sheriff's aids, which the feoffor is not bound to warrant. Also communal [022] fines set upon a whole county, as in the eyre of the justices and elsewhere, for [023] misdeeds, as where the county falls into mercy for a trespass; these are not [024] counted among services. There are also certain communal payments not termed [025] services, nor do they customarily arise except when the need for them occurs, as [026] hidages, cornages, carucages, and many others, introduced of necessity and by the [027] common consent of the whole realm, which do not belong to the lord of a fee and of [028] which no one is bound to acquit his tenant, unless in his charter he specially binds [029] himself to do so.
