(1) Summons shall be served upon all owners or holders who are residents of this state in like manner as in service of summons in a civil action if such owners and holders are known to the sheriff in the county in which the cemetery is located. If the defendants are not known to the sheriff, it is sufficient to serve the owners and holders whose names appear on the tax rolls of the county for the year previous to that in which the suit is started. The plaintiff is not required to mail a copy of the summons or complaint to nonresident defendants.(2) All owners and holders of such unimproved lots whose names do not appear on the tax rolls as aforesaid as shown by the return of the sheriff may be served by publication in any legal newspaper published in the county in which the cemetery is located for four consecutive weeks upon return of the sheriff that such owners and holders are not known and cannot be served in the jurisdiction of the sheriff.(3) The published summons shall contain the names of the record owners, as shown by the records of the cemetery authority, and "also all other persons unknown claiming any right, title, estate, lien or interest in the unused and unimproved portions of the cemetery described in the complaint," together with a brief description of the lot, or subdivisions of lots, pieces or parcels of the cemetery and a statement setting forth the order and judgment described in ORS 97.890(1) for which the plaintiff has applied to the court in the complaint. Such summons shall require all parties defendant to appear and show cause why an order should not be made declaring the unused and unimproved portions of the cemeteries to be a common nuisance, directing the cemetery authority to abate the nuisance, creating a lien thereon, providing that it be foreclosed and directing that the unused and unimproved portion of the cemetery be sold within four weeks from and after the date of the first publication thereof.
