What about investments (stocks) or properties? Can they also be put onto such trust?
Yes and Nedbank has its own investment platform also to make it easy. However the stocks don't even need to be on their platform it can be anywhere but will just make it a little more cumbersome to manage. Property, art, gold and literally most assets can be placed into the trust.
If so, why not to use such trust by default?
Well you can't control the assets in a discretionary trust. Also thinking you can stick stocks and bonds in there and then control them wont work. The term discretionary means the trustees decide how assets are distributed. A letter of wishes you create for the trust however can be used to provide guidance to the trustees. However it is also important if you have stocks in the trust to appoint a portfolio manager to the trust. Appointing one early helps in case you become a vegetable after a car accident for example and the trust needs the stocks to be manager. Nedbank provides portfolio managers as an extra service. You can discuss with them early your investment wishes and style or leave written instructions and if worst happens everything gets fully managed with them already appointed.
Does having such trust help or make it easier passing the wealth towards family members?
100% yes.
