N.Y. Lien Law § 83: Duration of lien

§ 83. Duration of lien. Every lien for a debt shall cease if the

vessel navigates the western or northwestern lakes, or either of them,

or the Saint Lawrence river, at the expiration of six months after the

first of January next succeeding the time when the debt was contracted,

and in case of any other vessel, at the expiration of twelve months

after the debt was contracted. If, upon the expiration of the time

herein limited in either of such cases, such vessel shall be absent from

the port at which the debt was contracted, the lien shall continue until

the expiration of thirty days after the return of such vessel to such

port. If proceedings are instituted for the enforcement of the lien

within the time herein limited, such lien shall continue until the

termination of such proceedings.
