After you file

Sorry for your loss.    And.....you and/or your sister need to consult an attorney.  Probate laws vary from one state to another, but the fact that your dad died intestate could be quite problematic if a large sum of money is involved.   Before you and your sister start dividing that money by two, or whatever you are doing, you need to determine whether there are any outstanding debts owed by the estate, which must be paid before you keep all the money from the account(s) and just divide the assets.
