Bouvier's Law Dictionary, Revised 6th Ed (1856):

AIDS, Engl. law. Formerly they were certain sums of money granted by the
tenant to his lord in times of difficulty and distress, but, as usual in
such cases, what was received as a gratuity by the rich and powerful from
the weak and poor, was soon claimed as a matter of right; and aids became a
species of tax to be paid by the tenant to his lord, in these cases: 1. To
ransom the lord's person, when taken prisoner; 2. To make the lord's eldest
son a knight; 3. To marry the lord's eldest daughter, by giving her a
suitable portion. The first of these remained uncertain; the other two were
fixed by act of parliament at twenty shillings each being the supposed
twentieth part of a knight's fee, 2 Bl. Com. 64.
