The respondent (Le Roux) signed a written contract on 15 January 1996 to sell to the first appellant, acting on behalf of a nominated trust, the western portion of Erf 186 R. The property was described in the contract as the “western portion of Erf 186 R as indicated on annexure ‘A’”, with subdivision still to be effected. Annexure ‘A’ was a sketch plan showing the erf and a straight dividing line separating eastern and western portions, partly drawn as a solid line and partly as a dotted line. The respondent later contended that the contract was invalid under section 2(1) of the Alienation of Land Act 68 of 1981 because the land sold could not be identified with sufficient certainty from the written contract without resort to inadmissible evidence. The appellants, as trustees, sued for enforcement. The Transvaal Provincial Division held the description inadequate and declared the contract invalid, prompting this appeal.
