An executor may accept from a debtor of the deceased estate who is unable to pay his or her debt in full, any reasonable part of the debt in discharge of the whole debt or grant any debtor of the deceased estate an extension of time for the payment of his or her debt in so far as this is compatible with section 35: Provided that if the debt exceeds R2 000, an executor shall, subject to the terms of the will (if any) of the deceased, not accept a part of the debt in discharge of the whole debt, unless he or she has been authorised to do so by the Master.
