Great-Nephew Challenges Aunt’s £400,000 Will Over Dementia Claim

Judges will decide whether dementia left Doreen Stock unable to change her will following her power of attorney revocation

Overview

  • Ben Chiswick, 39, filed a claim in June 2025 arguing his great-aunt lacked capacity when she replaced a 1986 will to disinherit him
  • Doreen Stock revoked a lasting power of attorney granted to Chiswick’s parents before leaving her Mottingham home and £400,000 estate to nephew Simon Stock and his wife Catherine
  • The dispute stems from a 2019 suggestion by Chiswick’s parents that Stock move into a care home, which prompted a contested capacity assessment
  • Simon and Catherine Stock’s barrister told the court that multiple assessments found her competent and that she shared a close, familial bond with them
  • Judge Jane Evans-Gordon heard both sides’ evidence this week and is expected to deliver a ruling at a later date
