What can I do if my brother kept his take of power of attorney of our mother from me, and while our mother was sick and used our mothers finances for himself, also gifting the property to himself. We are close to $100,000 over the last thirteen weeks. Our mother died last week, that day i found out about all of this when we went to the probate office to see about a will to pay for funeral expenses.... there is no will or estate holder. My brother is now threatenjng to refuse signature on probate with me to share the rest of the estate if I file against him for the money he used. What should I do?
