The appellant, a firm of attorneys, represented the respondent insurance company in approximately 400 matters under an oral mandate governed by an agreed fee structure and tariff. After disputes arose regarding fees and alleged arrears, the respondent terminated the mandate in March 2005 and demanded payment of monies collected by the appellant on its behalf. The appellant refused to pay over certain trust monies, asserting a right to set off disputed legal fees (which had not been taxed) against the collected funds. The respondent paid the undisputed portion of the fees and placed the balance into its attorneys’ trust account pending agreement or taxation, then sued for payment of the retained trust monies.
