A personal representative is legally obligated to use their best reasonable effort to administer the estate of which they are in charge. If they act in a way that is disloyal or negligent, it constitutes an abuse of their position and they are considered to be in breach of their "fiduciary duty". This is a legal abuse of authority and, accordingly, the personal representative can be removed fro their poition and face liability for any losses to the estate that their actions cause. In this case, the PR's apparent acts of self-dealing may well give rise to a legal claim. At this point you need to consult directly with an attorney who specializes in these type cases. They can go over all details of your situation and best advise you further.
