Stratgro Capital (SA) Limited entered into a written agreement with the Theo Lombard Family Trust to purchase immovable property, subject to obtaining finance. The agreement lapsed when finance could not be secured. Subsequently, through an oral arrangement, Stratgro introduced a third-party purchaser at a higher price, entitling Stratgro to a profit share of R1.5 million. After partial payment, the Trust refused to pay the outstanding R1 million, alleging the claim amounted to unlawful commission. Stratgro instituted proceedings to recover the amount. In the interim, the Trust obtained an order compelling Stratgro to provide security for costs, and the taxed costs were not timeously paid. The Trust caused a writ of execution to be issued and instructed the sheriff to attach Stratgro’s incorporeal right of action against the Trust and sell it in execution, without giving notice of the attachment to Stratgro. The right of action was sold in execution to the fourth respondent. Stratgro applied to set aside the attachment and sale; the High Court dismissed the application, leading to this appeal.
