In your situation, the title company will require more than the death certificate to transfer title to the heirs, or to sell the property to a third party. They are concerned with the dependability of the chain of title on the real estate. The title company will want to see documents establishing the identity of the heirs of the estate. Sometimes they will accept affidavits of heirship, if the circumstances are simple. Otherwise, the title company will require a letter testamentary (granted to the executor named in a will) an order admitting the will as a muniment of title only, or an order from the probate court identifying the heirs of the deceased.
