Oregon Revised Statutes Property Rights and Transactions § 97.610

When there are two or more owners of a burial plot or of rights of interment therein, such owners may designate one or more persons to designate the burials to be made in the plot and file written notice of such designation with the cemetery association. In the absence of such notice or of written objection to its so doing, the cemetery association is not liable to any owner for interring or permitting an interment therein upon the request or direction of any registered co-owner of the plot.
