ORS § 93.210
If a deed to real estate has been made to a grantee in trust or designating the grantee as trustee, and no beneficiary is indicated or named in the deed, a deed thereafter executed by such grantee conveying the property is presumed to have been executed with full right and authority and conveys prima facie title to the property. The grantee in the last-mentioned deed is under no duty whatsoever to see to the application of the purchase price. If the last-mentioned deed is recorded after June 7, 1937, after five years from its recording or, if it was recorded prior to June 7, 1937, then after June 7, 1942, the presumption is conclusive as to any undisclosed beneficiary and the title to the real estate, based upon the last-mentioned deed, shall not be called in question by any one claiming as beneficiary under the first-mentioned deed.
