The appellants in this case are former clients of the respondent firm of solicitors. They alleged that in the course of a contentious probate dispute concerning the will and estate of their late father, an oral agreement had been reached to cap their legal costs to those set out in their Precedent H costs budget. At first instance Master Whalan found that there had been no such agreement. This was upheld on appeal by Mr Justice Stewart. The decision provides a useful round up and examination of the law and principles related to both an appellate court’s approach to findings of fact and contractual interpretation.
