The LPA specifies that the LPA holders must consult with the third sibling. Does this affect your assessment? Presumably the requirement to consult does not allow a veto. Is that correct?
Yes it does. The LPA specifically states that the attorneys must consult with their brother who is named in the document.
A party can add restrictions or conditions to their LPA which are legally binding. They can also add guidance (which is not legally binding) to assist their Attorney on how theywant things done.
Therefore, if it is merely a ,note on guidance it is NOT legally binding.
I hope this helps.
