A major challenge to maintaining an accurate and updated system related to the fact that transfer of ownership only took place on registration. Information was not automatically updated when an individual's marital status or marital regime changed, for example. In December 2001, the Registrar of Deeds launched an electronic system, ie the Deeds Office Tracking System (DOTS), which enabled the Office to scan deeds into different tracking points. The data preparation took six days to finalise, unless there was a document missing and rejected. Government-subsidised houses were processed in three days. The conveyancers dealing with subsidised projects should apply to the Deputy Registrar of Deeds prior the registration in order to be awarded priority. In such instances, a red stamp is affixed onto the deeds indicating state-subsidised housing, and consequently expedited.
