In an action by several related corporations involved in appraisal and valuation services seeking to require their malpractice insurer to provide a defense in underlying actions alleging that plaintiffs breached their obligations relating to appraisals prepared in connection with asset-based loans plaintiffs made, the trial court erred in granting the insurer’s motion for summary judgment and dismissing plaintiffs’ motion for summary judgment, since the language used in the policies issued by defendant triggered defendant’s duty to defend, even though the appraisals at issue were used by corporations within plaintiffs’ family of related corporations to support the loans made by other corporations within plaintiffs’ family.
