The respondents, Mr and Mrs De Kock, were the registered owners of immovable property in George. In February 2006 they sold the property to the appellant, Mr Rhoode, subject to a suspensive condition that he obtain a loan for the full purchase price within twelve months. The loan was never obtained and the sale lapsed. Attempts in 2007 and 2008 to revive or extend the sale were invalid because Mrs De Kock, a co-owner married in community of property, did not sign the amendments as required by statute. Rhoode paid R400 000 towards the purchase price and remained in occupation, during which time he effected alterations and additions to the property without approved building plans. The De Kocks sought ejectment based on ownership (rei vindicatio). Rhoode resisted ejectment, alleging a lien for necessary or useful improvements and contending that ejectment could not be ordered without repayment or tender of the R400 000.
