Another day, another post about how long a mechanic's lien stays effective.  Today, we'll take a quick look at New York - one of the states in which a lien may be extended.  The time period in which an action to enforce a mechanic's lien must be initiated is necessarily congruent with the period of time the mechanic's lien remains effective; and that period is set in stone and cannot be modified or extended.  In New York, however, the lien claimant is able to extend the effective period of the lien, and have a longer time before which an action to enforce the lien must be initiated.
