In all suits and proceedings in any of the courts of this state in which any estate or interest in, or lien or charge upon registered land is in any way involved or affected, or any registered land is to be sold, or the title otherwise transferred, all persons shown by the registered certificate of title to have any interest in the subject matter of the suit or proceeding, and all other persons known or appearing to have an interest, shall be made parties and brought before the court and shall be bound by the orders, judgments, and decrees of the court in the same manner and to the same extent as in the initial registration of title to land as provided in sections 5309.02 to 5310.21, inclusive, of the Revised Code. The residence and post-office address of any party in interest as shown by the certificate of title, or memorials, or memorandums indorsed thereon in the office of the county recorder, unless known by the plaintiff or party required to cause notice to be given to be incorrect, may be regarded as the correct residence and address of such party in interest and service made accordingly whether he resides within or without the state. In any matter or proceeding before the recorder in relation to registered land, or any interest in, or lien or charge upon such land, when notice is required to be or may be given, such residence and address, in the absence of knowledge to the contrary, may be regarded as correct and service made accordingly. In all such suits and proceedings in any court of the state or matters or proceedings before a recorder relating to registered land, or any interest in, or lien or charge upon such land, service of summons or notice may be made on any party in interest by the clerk of such court or recorder by mailing to such party such summons or notice in a registered letter with a five days' return card thereon, directed to his post-office address as shown by the registered certificate of title, or if not so shown, to his known post-office address. If said letter is not returned by the postal authorities to the officer mailing it, such service is deemed to have been made. If said letter is so returned, upon the filing of an affidavit of the plaintiff, or other party required to give notice, or his attorney, that he does not know and after diligent research has been unable to learn of any other residence and address of such party in interest than those stated in the registered certificate of title, or that he has been unable to learn the residence and address of any person in interest whose name, residence, and address is not so shown by the registered certificate of title, if such person in interest is shown by the registered certificate or is known to be a resident of this state, summons as provided in civil actions shall be issued for him to the sheriff of the county of his residence as so shown or known, and if returned "not found," such person and also such like person not so shown or known to reside in the state, may be served by publication as in other cases, or as in original registration, as one whose residence is unknown. Unknown heirs and devisees, and all other unknown persons, whether in being or not, under the designation of "whom it may concern" may be made parties and served by publication as in original registration or as in other civil cases, and all such persons so made parties and so served shall be bound by the judgment or decree with no right to question such judgment or decree except upon appeal, or for fraud of the successful party in procuring such judgment or decree to be asserted only against persons not bona fide purchasers or encumbrancers, or persons holding under them, by suit to be brought within one year from the entry of such judgment or decree.
