Thank you for your question
My name is ***** ***** I shall do my best to help you.
I am sorry but there is no such provision.
You have no claim whatsoever on any assets until your Aunt dies - nor can any gift now be made to reduce Inheritance Tax now that her assets have to be dealt with under the Power of Attorney
I am sorry to give disappointing news
Please ask if you need further details
No I am afraid that is not possible in these circumstances in the UK
