Two middle-aged brothers have been censured after a judge was told that they treated a sick elderly aunt's money as "their own private bank".
The 86-year-old woman, who has dementia and lives in a care home, gave her nephews the power to act as her attorney seven years ago, Judge Denzil Lush was told.
But a local authority with responsibility for the pensioner's welfare raised concerns about the way the woman's finances were being handled and an investigation was launched.
Detail of the case has emerged in a written ruling by the judge following a hearing in Court of Protection - which handles cases involving sick and vulnerable people - in London.
Judge Lush concluded that the two men breached their fiduciary duties and revoked their power to act as the pensioner's attorney.
