A disinherited nephew could face jail over claims he threatened to "beat the sh*t" out of "w**ker" lawyers after his aunt left her £200,000 fortune to charity.IT expert Sean Stimson has been locked in a bitter row over the will of his late aunt, Helen Smith, since she died in 2021, leaving her estate to the RSPCA and other causes.Mr Stimson claims that she had always intended that her Swindon home - which formed the majority of her fortune - to stay in the family, but instead it went to the charities under a 2016 will.He is still disputing the will, but has now been dragged to court by the charities' lawyers, Foot Anstey LLP, accused of a campaign of "vitriolic" threats and abuse against them and their employees.The nephew is accused of writing to the law firm, addressing them as "w**kers" and "b*tches" and threatening to "beat the sh*t" out of them if his aunt's house is not returned to him.The firm says the "abuse" puts him in contempt of court for breaching a previous court order - banning Mr Stimson from such conduct - which settled a Foot Anstey harassment claim against him last year.Sean Stimson outside court (Champion News)But Mr Stimson is fighting the contempt application - which could see him jailed for up to two years - denying that he was behind the letter.Although he admits sending an email to say his case would be "defended with force," he says that was not intended as a threat of violence and that he had nothing to do with the "w**kers" letter.In a previous judgment on the dispute between Mr Stimson and the law firm, High Court judge Mrs Justice Hill set out the background to the row."His aunt left a will made in 2016 which made provision for three animal charities and a hospice to recover under her estate," she said.“It made no provision for Dr Stimson and this led to a dispute between him and Foot Anstey, who are the administrators of the estate, instructed by the beneficiary charities.”Mr Stimson disputed his aunt’s will on grounds that she lacked sufficient mental capacity and understanding to make her 2016 will, also claiming that another later will of 2020 set out her true wishes about her £200,000 home in Cloudberry Road, Swindon.But Mrs Justice Hill said that, on the evidence she had seen, he had not been able to “substantiate these assertions” and since then probate has been granted to the charities involved.He has continued to dispute the validity of the will, but ended up in court after Foot Anstey accused him of a campaign of harassment against them amid the will row.The £200,000 home in Cloudberry Road, Swindon.

I have had enough of your cr*p and the jails are full so I will just keep coming for you until you comply or are permanently hospitalised.”Ms Wilson said the “b*tches” reference was especially troubling as the staff members who had worked on the charity will dispute were women.The letter was a “clear breach of the undertakings” and contained a “direct threat”, the barrister argued, adding: “the vitriolic nature of that abuse added to the intensity of the threats of violence”.She asked the judge, Mr Justice Griffiths, to find Mr Stimson in contempt of court for breaching the undertakings, with the potential then for a prison sentence.But Daniel Mullin, barrister for Mr Stimson, denied the "w**kers" letter had anything to do with his client, pointing out that the postmark was nowhere near his address."The claimants are totally incapable of proving to the relevant standard who sent the letter. The evidence relied upon by Foot Anstey is wholly insufficient," he continued.“It is accepted that the letter has the defendant’s typed name on the bottom and referred to the returning of ‘an aunt's house’. This is not direct evidence."Fingerprints or DNA on the letter would not be considered direct evidence, so it cannot be the case that a simple typed signature is direct evidence.”On the matter of the June email, he said the terms had been misunderstood and contained no underlying threat of violence, but was merely him stating his intention to pursue his case about the will.“The language in the email is consistent with the defendant intending to convey that he would defend his position fully and to the limit of his ability - ‘with force’ being synonymous, for example, with robustly,” he told the judge.After three hours of evidence and submissions from both barristers, the judge reserved his decision in the case, to be given at a later date.If Mr Stimson is found in contempt of court, he could be jailed for up to two years or receive an unlimited fine.
