A man was written out of his dad's £1million will because of lies his sister told about him.
But Sonia Whittle has now been disinherited from the post-humous document after it emerged she had turned her late father Gerald against her brother David.
She made a string of false accusations against him before David died having suffered with leukaemia, a court was told this week.
Sonia falsely labelled her brother and his wife as "psychopaths" and "criminals" to their elderly dad in a "disgraceful" attempt to cut them out of the will, the court heard.
She also failed to tell David of their father's death and hid the £1m inheritance of antiques and classic cars from him.
In a landmark ruling delivered this week, a High Court judge has ruled the will "invalid" on the grounds that it was obtained fraudulently and through undue influence.
Known as ‘fraudulent calumny’, it is only the third court ruling of its kind since 2007.
Delivering the verdict on Tuesday at Bristol High Court, District Judge Tony Woodburn described it as a “disgraceful” and “appalling” attempt to cut rightful beneficiary out of will.
The court heard father-of-two Gerald died aged 92 in December 2016, just three weeks after executing his will and appointing daughter Sonia and her partner, Ray Spicer, as executors.
Apart from a bequest to David of Gerald’s old cars, the entire estate, valued at approximately £1m was left to Sonia and Ray.
The court heard that Gerald's solicitors sent a trainee legal executive to his house to take instructions for the will.
During the meeting, Sonia told the legal executive that David and his wife Julie were “psychopaths and criminals” who had stolen large sums of money from Julie's mother.
The judge said: "It is clear Sonia immediately launched into an assassination of the characters of both the claimant and of his wife.
"Having rubbished her brother's character, Sonia then left to take Gerald's dog for a walk. It was against this immediate background that Gerald apparently proceeded to give instructions to Ms Spanner for his will."
Sonia also made claims that David had been looking for Gerald’s bank details while he had been in hospital, and that he had stolen his antiques and classic cars.
She also lied about the couple forcing their way into Gerald's house and that police had issued a harassment order against them.
But David told the court he had 'a good relationship with his father'; and argued that he visited his him regularly - at least once a week since his mum died in 2005.
He claimed that on October 15, 2016 he visited his dad's home where he overheard a conversation between Gerald and Sonia.
"Prior to entering his father's room overheard a conversation between (his sister and his father) telling him her brother had stolen money from his mother-in-law and that he was 'a violent man who assaulted women'," Judge Woodburn said.
Less than a month later Sonia made false claims to the trainee legal advisor.
The defendants denied fraudulent calumny.
Sonia admitted to making 'negative comments' about David on 11 November 2016, but claimed "truthfulness in the comments made" according to the verdict. Neither defendant's attended the hearing.
In giving his verdict, Judge Woodburn said: "On all of the evidence presented to me, it is abundantly clear that the aspersions cast on the characters of both David and his wife, are not merely unproven by (Sonia), but, I find, are completely false.
"The issue then arises as to whether Sonia's falsehoods so tainted Gerald's mind and thoughts that he was compelled to exclude David from a more substantial share in Gerald's estate?
"Was Gerald so pressured by the weight of (Sonia's) allegations as to be persuaded to marginalise David in the way described in the will?"
"From August to early November 2016, Gerald moved from 91 to 92 years of age, he was attempting to live with the debilitating diagnosis and condition caused by leukaemia; his health was deteriorating; he was prone to confusion and was physically frail."
The judge ruled Sonia "attempted and succeeded in falsely and unduly influencing" Gerald to marginalise or exclude David from a substantial share in the estate.
"The claimant has clearly succeeded in proving fraud and undue influence," Judge Woodburn added.
Speaking after the case, Amanda Noyce, partner and Head of the Inheritance Disputes Team at Royds Withy King, who advised David, said: "David had worked, until retirement, in a highly vetted position and Disclosure and Barring Service certificates proved that neither he nor his wife had ever been involved in any illegality.
“This has been a terrible ordeal for David and Julie, who have endured intense emotional trauma on every level. They were very close to Gerald, saw him very regularly and were central to his care in his later years.
"Sonia sought to poison her brother’s relationship with their father and, furthermore, to cut contact between Gerald and David right at the very end, when Gerald was most vulnerable and most in need of his son’s love and care.
“She even refused to allow the medical authorities and social services to let David know when their father had died. It was not until two months after Gerald`s death that David eventually found out - after much increasingly frantic searching and investigation."
