A testamentary trust fund can be established with a provision in the event of death (will).
By establishing conditions for payment, the founder can determine the purpose or otherwise control pay out to heirs, even after his/her death and prevent, for example, the misuse of assets.
The founder is thus assured his/her estate will be handled in accordance with his/her will, and can ensure the effective inter-generational transfer of his/her assets through a testamentary fund.
