N.Y. Abandoned Property Law § 202: Parties to action

§ 202. Parties to action. There may be made parties to such action,

all persons who would have, might have or might claim to have any

interest in or lien upon the premises so escheated or forfeited, at the

time of such escheat or forfeiture, and all persons in possession of

such real property. Where the names of the defendants are unknown, they

may be designated as "unknown defendants." The provisions of law

applicable to actions to recover real property shall apply to such

actions, except that service of the summons shall not be deemed to be

complete until, pursuant to an order of the court, the summons together

with a notice directed to the defendants setting forth the object of the

action, a brief description of the land affected, the source and manner

in and by which it is alleged that said real property shall have

escheated or forfeited to the people, and the name or names of person or

persons whose title or interest shall have so escheated or have been

forfeited, shall have been published once in each week for four

successive weeks in two newspapers designated in the order for such

publication as most likely to give notice to the defendants to be

served.
