Overview

• Jonathan Marcus has appealed a High Court decision that allowed his half-brother Edward to share their late father’s £14.5 million Kitfix Hobbies trust despite Edward’s non-paternity.
• Edward learned in 2010 from his mother that he was the product of Patricia Marcus’s affair with lawyer Sydney Glossop, but Jonathan only discovered the secret in 2023.
• In the original 2024 ruling, Master Marsh acknowledged Edward’s lack of biological ties yet concluded that Stuart’s intent to benefit both named sons took precedence.
• At this week’s appeal hearing, Jonathan’s barrister argued the ordinary meaning of ‘children’ excludes non-biological offspring while Edward’s counsel maintained the trust context reflects their father’s clear intention to provide for both brothers.
• After summarizing final submissions, Sir Anthony Mann reserved judgment on whether Edward’s status should exclude him from the family trust, with a decision expected at a later date.
