In Miller v. Sanchez, 6 Misc 3d 479 [Civ Ct, Kings County 2004], a small claims action, Justice Jack Battaglia held that a single repair estimate, prepared by a mechanic employed by defendant's insurance carrier, was admissible to establish the extent to which plaintiff's automobile was damaged. He reasoned that The unity of interest between defendant and its carrier, and the carrier's authority to act on defendant's behalf to resolve the claim, are sufficient to render the carrier's estimate admissible against defendant (id. at 483.)
