I am advising a client on a suitable trust structure for grandchildren. All minors. The trust will hold shares in a private company. Intention is for the shares to be held on a bare trust with the father of said children acting as trustee. In addition the grandmother (settlor) would like the trustee to be able to exercise the voting power on the shares until the children reach the age of say 25. Is it possible to put in such a contingency without affecting the element of the bare trust or does the contingency create a normal settlement as opposed to a bare trust?
