New York Consolidated Laws, City Civil Court Act - CCA § 302. Real property actions;  venue

(a) transfer the entire action to the county wherein the real property is situated, if the transfer may be effected without prejudice to the rights of any party;  or

(b) strike the real property cause of action, no matter by whom asserted, without prejudice to the party asserting it to commence it in the proper county.

If more than one real property cause of action appear, the court may make such disposition as is just under the circumstances, and a real property action, no matter by whom asserted, may be tried in a county other than that in which the real property or a part thereof is situated only if there is reason to believe that an impartial trial cannot be had in the latter county.
