The children of F1 legend Sir Stirling Moss are fighting each other in court over his £20million fortune and a helmet that saved his life. 

Elliot Moss and Allison Bradley are locked in a legal battle over the estate of Lady Susie, Sir Stirling's third wife, who inherited most of his estate when he died aged 90 in April 2020.

When Lady Susie passed away herself aged 69 in 2023, it emerged that her will - made in January 2022 - had left her entire estate to Allison, 59, Sir Stirling's daughter from his second marriage to Elaine Barbarino. 

Elliot lodged a caveat with the probate registry preventing the administration of her estate, prompting Allison to begin legal proceedings seeking to force the execution of the will and begin the probate process.

But Elliot, 44, has launched a counterclaim that contests the validity of Lady Susie's 2022 will - claiming in court documents that she was suffering from a mental disorder at the time.

Instead, he wants Lady Susie's earlier 2002 will to be recognised, which would see a 75-25 split in his favour.

Crucially, this would also leave him with a helmet Sir Stirling was wearing during a 1962 crash at Goodwood that put him in a month-long coma and ended his top-level racing career. 

In a counterclaim seen by the Daily Mail, Elliott accuses people around Lady Susie of seeking to 'poison' his mother's mind against him while she allegedly suffered from depression and an alcohol addiction after the death of her husband - prompting her to cut him out.

The document refers to a family friend who allegedly 'continued to supply Lady Susie with alcohol when he visited'.

The friend is accused of seeking to influence Sir Stirling's decisions about his estate when he remained alive, and allegedly inserting a clause into Lady Susie's 2022 will that allowed him to 'charge for his executorship services'.

He is not named as a party in the case. 

Tracey Angus, KC, acting for Elliot, suggests Sir Stirling's death in 2020 prompted Lady Susie to develop a 'complex bereavement disorder' that prompted her alcohol dependency and depression to worsen. 

'Following Sir Stirling's death, Lady Susie would carry the urn containing his ashes with her, cradling it and on occasions dabbing his ashes behind her ears,' she writes in one passage. 

'By January 2022, Lady Susie had withdrawn into herself completely and often did not know what day or date it was.

'She would forget conversations which she had had the previous week and had no idea what was going on in the world around her.' 

Ms Angus claims that Lady Susie's 'disorder' led her to develop 'feelings of bitterness and a loss of trust towards others to whom she had formerly been close and whom she had trusted – particularly the Defendant (Elliot)'.
