Substratum – What is it and do I need to worry about it?
There has been debate between legal academics and trust practitioners about whether a power holder is prohibited from exercising powers of addition or exclusion of beneficiaries, or other analogous powers, when the proposed change is so significant that it has the effect of changing the basic purpose, or ‘substratum’ of the trust. That is to say, the exercise of trust powers would result in an outcome closer to a fundamental change to the purpose of the trust itself than a simple variation, or addition or exclusion of beneficiaries.
