Joseph is an experienced lawyer in the field of proabte -- the complicated court procedure that governs the processing and distribution of estates subject to the supervision of a judge.  The court formally appoints an executor who then inventories your assets, pays off your debts and distributes the balance, if any, to your heirs.
