I am the only sibling. I live in Phx, AZ and they live in Kansas City KS. I didn't know she gave her 2 older children POA until my father passed away after she died. My sister passed away last June 2017 and my father passed away this past February 2018. The POAs have not shared any details of what is to be done and I being the only sibling alive and out of state, what rights do I have to any financials?
