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

SEPARATE MAINTENANCE, contracts. An allowance made by a husband to his wife
for her separate support and maintenance.
     2. When this allowance is regularly paid, and notice of it has been
given, no person who has received such notice will be entitled to recover
against the husband for necessaries furnished to the wife, because the
liability of the husband, depends on a presumption of authority delegated by
him to the wife, which is negatived by the facts of the case. 2 Stark. Ev.
