Authority to Collect Decedent's Money

My father passed away on March 1, 2009. He had a joint bank account with my oldest brother. My oldest brother cashed by father's final checks (one social security and two annuities) and spent the majority of the money on his own rent and utilities. There is about $700 left in the joint bank account. Now, here is the twist. My oldest brother passed away on March 27, 2009. The bank account has been frozen. No one in the family wants to administer either estate and no one has enough money to hire an attorney. All personal property has been distributed. There is no real estate.

My mother passed away before my father passed away so, his only beneficiaries are my brothers and me. My oldest brother who passed away 26 days after my father never married and does not have any children. They both lived in the same rented house in Portage County, state of Ohio.

The only asset that is left in both estates is the money in this joint bank account. Is there any way to get these funds (ie. letter of authority) without administering either estate? Additionally, my brother has unclaimed funds (under $100) that are being held by the state of Ohio. Is there any way to claim these funds without administering his estate?
