The answer is it depends. If the estate is large enough to have probate (assuming no trust document or gifts that went directly to beneficiaries like bank accounts and insurance benefits), then you need to open probate. Once the proibate hearing is done, that is it. You will need to file a document indicating that the matter has been concluded, all items have been given to beneficiaries, or debts paid and the like. Contact your local courthouse for more information.
