Such register shall attach to such notice a plain copy of the will and codicils of such decedent, if he dies testate, or, if he died intestate, a list of his heirs and next of kin, so far as is known to such register. Within sixty days after the mailing of such notice the official or body charged with the administration of the death tax laws of the domiciliary state may file with such probate court in this commonwealth a petition for an accounting in such estate, and such official or body of the domiciliary state shall, for the purposes of this section, be a party interested for the purpose of petitioning such probate court for such accounting.
