A liquidator in insolvency proceedings may only take into possession or control assets and property to which the company is entitled at the commencement of liquidation. Where a company has entered into valid agreements of sale, received payment, relinquished rights, title and interest in property, and allowed purchasers to take possession and make improvements, such property cannot be included in the liquidation process as it no longer belongs to the company. The requirements for granting a final interdict (as set out in Setlogelo v Setlogelo) are: (a) a clear or definite right established on a balance of probabilities; (b) an injury actually committed or reasonably apprehended; and (c) the absence of similar protection by any other remedy. A person may have locus standi to institute proceedings on behalf of others where clear proof exists of authorization, even if not in writing, and such determination must be made on the facts of each case.
