Betty Rogers died on 6 November 2004 in Harare. She had executed three wills: (1) a will dated 6 January 1995 executed in the United Kingdom bequeathing her UK immovable property to her two children (the appellant and first respondent) in equal shares and naming both as executors; (2) a will dated 23 March 1999 dealing with her Zimbabwean estate; and (3) a will dated 22 January 2004 executed in Harare which contained a general revocatory clause revoking all former wills and bequeathed her entire estate to her son, the first respondent, thereby disinheriting her daughter, the appellant. The appellant challenged the validity of the 22 January 2004 will, alleging the first respondent had exerted undue influence on the testatrix. She alleged he was a single, unemployed man who abused drugs and alcohol, became verbally and physically abusive, and caused the testatrix to be frightened. However, the appellant refused to plead specific particulars of the alleged undue influence when requested, stating these were matters of evidence. The first respondent brought an application under Order 11 rule 75 for dismissal of the action as frivolous or vexatious.
