Sarah and Paul Hewitt represent Mrs Cowan in her claim for reasonable financial provision from the estate of her late husband. In July 2019 the Court of Appeal unanimously gave her permission to bring her claim notwithstanding it having been issued out of time. Here is a link to the Court of Appeal Judgment and to our article. Trial is due at the end of July 2020.

Sarah and Dawn Goodman for the successful beneficiaries in The Matter of the A Trust [2012] JRC 169A, where the Royal Court of Jersey made new law on the scope of the duties of trust protectors and the grounds on which they may be removed from office. The Royal Court found that, as with trustees, the correct test for removal of a protector arises from Letterstedt v Broers. Due not only to the protector’s misunderstanding his duties to his beneficiaries but also his failure to keep a watchful eye on the trustee’s management of the trusts, the Royal Court suspended his powers and removed him from office.
