ORS § 97.730
Gifts, grants and bequests of personal property in trust for the purpose of providing perpetual care and maintenance, improvement or embellishment of private burial lots in or outside of cemeteries and of the walks, fences, monuments, structures or tombs thereon, are permitted and shall be deemed to be for perpetual and benevolent uses. They are not invalid by reason of any indefiniteness or uncertainty of the persons designated as beneficiaries in the instrument creating the trust; nor are they invalid as violating any existing laws against perpetuities or suspension of the power of alienation of title to property. But nothing in this section affects any existing authority or cause to pass upon the reasonableness of the amount of such gift, grant or bequest. Any cemetery association may act as trustee of and execute any such trust with respect to lots, walks, fences, monuments, structures or tombs, both within or outside its own cemetery limits, but within the county where such cemetery association has its principal office and place of business, whether such power is otherwise included in its corporate powers or not.
