Bouvier's Law Dictionary, Revised 6th Ed (1856)
OUSTER LE MAIN. In law-French, this signifies, to take out of the hand. In
the old English law it signified a livery of lands out of the hands of the
lord, after the tenant came of age. If the lord refused to deliver such
lands, the tenant was entitled to a writ to recover the same from the lord;
this recovery out of the hands of the lord was called ouster le main.
