Order unanimously reversed on the law with costs and plaintiffs' motion granted. Memorandum: Plaintiffs' motion to amend their bill of particulars to assert as an item of damages a claim for the future institutional care of Richard Horvatis should have been granted. In view of the liberal policy allowing amendment of pleadings even after trial in the absence of prejudice to the opposing party (see, Loomis v. Civetta Corinno Constr. Corp., 54 N.Y.2d 18, rearg denied 55 N.Y.2d 801), leave to serve an amended bill of particulars should be freely granted (see, Kerlin v. Green, 36 A.D.2d 892; Bernas v. Kepner, 36 A.D.2d 58). Defendants cannot claim prejudice, since plaintiffs' medical reports clearly apprised defendants of Richard Horvatis' deteriorating condition and the possibility of institutional care. Plaintiff Richard Horvatis should be required to submit to a physical examination and to an examination before trial if so requested by defendants (Bernas v. Kepner, supra, at 60).
