Q: My brother is POA over my family's finances..is it possible for my brother to change finances to suit him better?

A: Whether or not you inherit anything is not your decision nor something you are owed or due or have 'coming to you' or even anything you have a right to at this point. It is your families finances and / or property and as such they are allowed to do with it pretty much anything they want. It is up to the members of your family who the estate belongs to (or to the laws of intestate succession if they die without a will) to decide who gets what and frankly that is as it ought to be. So if you are asking is it possible for your brother to do shady things behind your back to convince or even manipulate your family members to leave more or even everything to him and / or to misuse family money to his or others benefit, then - the answer is yes. However as POA agent, your brother does have a fiduciary duty to the principle (your family) meaning, he is typically only to use the money in the best interest of the principle. He should also be keeping receipts and managing a record of expenditures and make at least an annual accounting - very much like a trustee. You can potentially check on what your brother is doing but you should likely consult with a local attorney on how to best do that. If you poke around in your family's financial business too much or in the wrong way, it is you who could come out as the weasel and weasels typically do not fair well when it come to inheritance.
