N.Y. Real Property Actions & Proceedings Law § 933: Effect of judgment after sale

§ 933. Effect of judgment after sale. A final judgment after sale is

binding and conclusive upon the same persons upon whom a final judgment

for actual partition is binding and conclusive; and it bars each of

those persons who is not a purchaser at the sale from all right, title

and interest in the property sold. It is also a bar against each person

not a party who, at the time when it is entered, has a general lien by

judgment or decree on the undivided share or interest of a party, if

notice was given to appear before the referee and make proof of liens,

as prescribed in this article, and also against each person made a party

who then has a specific lien on any such undivided share or interest;

but a person having any such specific lien appearing of record at the

time of the filing of the notice of the pendency of the action, who is

not made a party, is not affected by such judgment.
