  (6)  No personal representative of a personal representative, in consequence thereof, shall be a personal representative of the first decedent.

  2.  When any corporation is named as personal representative in any will hereafter executed, and qualifies as such, the presumption is that the will was not prepared by a salaried employee of such corporation.  However, upon the application of any heir or devisee, made in the probate division of the circuit court of the county for the removal of such personal representative, said presumption may be rebutted by evidence satisfactory to the court hearing the application, unless the will or some codicil or certificate attached thereto contains a recital that at or before the execution of the will the testator had advice or counsel in relation thereto from someone not under salary from such corporation.  In the absence of such recital, the court may on such application and upon satisfactory evidence that said will was prepared by a salaried employee of the corporation revoke the appointment of and remove such corporation as personal representative.

  3.  Before a nonresident of this state or a corporation organized under the laws of another state or country is issued letters testamentary or of administration he, she or it shall file in the probate division of the circuit court a designation, including the signature and address, of a resident of this state, or a corporation of this state authorized to administer trusts, as agent for the service of process on and the receipt of notice by such nonresident or foreign corporation.  This designation shall be recited in the letters testamentary or of administration.  Such a designation may be revoked only by a new designation of an agent for service and notice in this state, which shall be endorsed on the letters testamentary or of administration.  By filing such designation, the nonresident submits personally to the jurisdiction of the court in all proceedings relating to the administration of the estate and to the performance of his fiduciary duties until discharged of those duties by the court.

  4.  Service of process may be made upon a personal representative who is a nonresident of this state, or a corporation organized under the laws of another state or country, by registered or certified mail, addressed to his, her or its last reasonably ascertainable address.  Notice by ordinary first class mail is sufficient if registered or certified mail service to the addressee is unavailable.  Service may be made upon such a personal representative in the manner in which service could have been made under other laws of this state on either the personal representative or his decedent immediately prior to death.  If service is made upon a personal representative as provided in this subsection, he shall be allowed at least thirty days within which to appear or respond.
