An Inheritance and Estate Tax Waiver or other consent to transfer issued by the Secretary of Revenue bearing the signature of the Secretary of Revenue or the official facsimile signature of the Secretary of Revenue may be registered by the Register of Deeds in the county or counties where the real estate described in the Inheritance and Estate Tax Waiver or consent to transfer is located in the same manner as deeds, and for the same fees, but no formalities as to acknowledgement, probate, or approval by an officer shall be required.  The name of the decedent owning the real property at death shall appear in the “Grantor” index.  Nothing herein shall require a personal representative or other person interested in the decedent’s estate to register Inheritance and Estate Tax Waivers or consents to transfer.
