Can a trust have more than one founder?
The trite answer is “Yes”. But ask me the question and I would say “Why are you thinking of that?”
Firstly, is there any benefit to being a founder? The founder has no power once a trust has been formed. The only time their existence is relevant is if the trustees wish to change the trust deed. This cannot happen during the founder’s lifetime without his/her approval.
Secondly, is there any disadvantage in having two founders? Just clutter, in that again, the trust deed cannot be changed during the lifetime of the founders without their consent.
So, my view is “Keep it simple”.
