The respondents were the joint trustees of the insolvent estate of Jurgen Harksen. The appellant purchased an expensive property in Clifton and, in February 2001, entered into a written lease which reflected Mrs Jeannette Harksen (the insolvent’s wife) as lessee. The lease was for ten months at a rental of R25 000 per month plus expenses, and substantial payments were made to the appellant. The trustees later sued the appellant for repayment, alleging that the true lessee was the insolvent himself, that the lease in Mrs Harksen’s name was simulated, and that the insolvent had paid the rental without the trustees’ knowledge or consent. The High Court found the transaction to be simulated and held the lease voidable at the instance of the trustees under s 23(2) of the Insolvency Act.
