A woman tried to challenge her mother's will after she was left £100 and her brother bestowed tens of thousands of pounds of assets.
But Patricia Johnson lost her High Court fight today after a judge decided Maudlin Bascoe had "testamentary capacity" when her will was executed in her 80s.
The High Court hearing in London was told Ms Johnson questioned the validity of the document and believed her brother Bradford Barnaby put her under "undue influence".
Deputy Master John Linwood though dismissed the claim and described the will as "rational".

Mrs Bascoe, who lived in Brixton, south London, died in the summer of 2015 aged 96. She made the will around a decade earlier.
And a note in the document said Mrs Johnson had shown "very little care and concern for me in my later years" and had been "rude" and "unpleasant".
The proceedings today heard the mum was born in Jamaica and had worked as a seamstress after arriving in London in the 1960s.
