The wife of Lord Lucan, who vanished more than 40 years ago after murdering his children's nanny, cut her children out of her will on account of having "a lack of good manners".
A probate document has revealed that Veronica, the Dowager Countess of Lucan who died from a cocktail of drink and drugs last September after incorrectly diagnosing herself with Parkinson's disease, refused to leave a penny of her £576,626 estate to her son, George, the 8th Earl of Lucan, or to his sisters, Lady Camilla Bloch, QC, and Lady Frances Bingham.
She stated in the document: "In view of the lack of good manners and reverence shown to me as their parent, I do not wish any of my three children to benefit from my death any more than they have to."
Lady Lucan spent her final years as a recluse, having not spoken to her sister or her three children, George, Frances and Camilla, since the 1980s.
She has left her entire estate to the homelessness charity Shelter. George, who married Anne-Sofie Foghsgaard, the daughter of a wealthy Danish industrialist, in 2016, said: "I applaud the decision."
Custody of Lady Lucan's children was transferred to her sister, Christina Shand Kydd and her husband, Bill, after Lady Lucan reportedly became mentally ill.
While her Belgravia home was thought to be worth millions she did not own the property and it is reported that she had hoped her memoirs would provide her with the money for a new kitchen.
The aristocrat's possessions, including a large oil portrait of her husband and a personalised top hat, will be sold at an auction in Oxfordshire next month, according to the Mail.
Lady Lucan was found dead in the same two-storey terraced town house in Belgravia, central London, from which her husband had disappeared almost 44 years earlier.
The inquest into Lady Lucan's death heard that she had convinced herself that she had Parkinson's disease. She was said to have noticed a tremor in her right hand, was unable to sleep, thought she was losing her sense of smell, felt tired, anxious and was becoming forgetful.
Lord Lucan disappeared in 1974 after killing his children's nanny when he mistook her for his estranged wife. Lady Lucan had always maintained that her missing husband had committed suicide.
