If the commission is satisfied, upon the hearing or from the report of the fiduciary commissioner, that the legal presumption of death is established, the commission shall so declare by order, shall then proceed to hear, and to grant, if proper, the application for probate of the will of such supposed decedent, if such there be, and to grant letters testamentary or of administration, as the case may require, to the party entitled thereto, who shall qualify and give bonds as in cases of persons known to be dead. The probate of any such will and such letters, until revoked, and all acts done in pursuance thereof and in reliance thereupon, shall be as valid as if the supposed decedent were in fact dead.

Immediately upon the entry of such order declaring that the legal presumption of death is established, the commission shall direct the clerk thereof forthwith to make and deliver to the state registrar of vital statistics the order and such personal data and other information from the records of the proceedings as may enable the state registrar of vital statistics to issue a death certificate. Upon receipt of the order, personal data and other information, the registrar of vital statistics shall forthwith issue and deliver by mail unto the clerk of the county commission wherein such order was entered, a death certificate in the form prescribed by law, except that no medical certification shall be required. The clerk shall record such death certificate in the manner set forth in section nineteen, article five, chapter sixteen of this code.
