The Appellate Division modified the Order which, to the extent appealed from as limited by the briefs, denied defendants' motion to compel production of plaintiffs' nonprivileged litigation files in another action, to the extent of granting defendants' motion for discovery, and remanding the matter for further proceedings to narrow the scope of the discovery, and otherwise affirmed. In a partition action against each other, plaintiffs mother and son placed into contention issues of property ownership, economic losses, mismanagement, and lack of property maintenance. As this action gives rise to similar economic issues, defendants are entitled to nonprivileged information contained in that action that is relevant to the defense of this action, since CPLR 3101(a) mandates full disclosure of matters that are material and necessary in the prosecution or defense of an action. The confidentiality order in the partition action cannot operate as a shield to preclude plaintiffs from having to produce relevant documents in this action, especially since they affirmatively place into contention similar economic issues. However, defendants are not entitled to the entirety of the nonprivileged litigation files. To the extent that documents and information contained therein relate exclusively to other properties owned by plaintiffs, and not to the property at issue in this action, the information is not relevant, and plaintiffs are not under an obligation to produce it.
