The appellant and another person, Janse van Rensburg, were appointed joint provisional trustees, and later joint trustees, of an insolvent estate. Each trustee separately signed a standard-form undertaking and bond of security in favour of the Master of the High Court, binding himself to properly administer the estate and to be liable up to a stated amount for loss caused by his own failure or maladministration. Fedsure, an insurer, furnished suretyships to the Master securing the trustees’ performance. Van Rensburg later forged the appellant’s signature on a power of attorney, sold estate property, and absconded with the proceeds. The Master called upon Fedsure to make good the loss, which it did. Fedsure then sought to recover the amount from the appellant alone, alleging joint and several liability as co-trustee, despite the appellant’s innocence and lack of negligence.
