*354To sustain a cause of action for abuse of process, the plaintiff must demonstrate “the deliberate premeditated infliction of economic injury without economic or social excuse or justification” (Board of Educ. v Farmingdale Classroom Teachers’ Assn., 38 NY2d 397, 405). Commencement of an action, even with malicious intent, is insufficient (Curiano v Suozzi, 63 NY2d 113, 116-117; Family Media v Printronic Corp., 140 AD2d 151, 152). In addition, the process employed must entail some “ ‘unlawful interference with one’s person or property’ ” (Curiano v Suozzi, supra, at 116, quoting Williams v Williams, 23 NY2d 592, 596). We note that defendant’s right to assume his brother’s tenancy was hardly free from doubt, and this litigation therefore possessed a valid legal basis. Finally, no specific, quantifiable damages were demonstrated to be attributable to this or any other tort advanced as the basis of a counterclaim by defendant.
