Oregon Revised Statutes Protective Proceedings; Powers of Attorney; Trusts § 130.570

Property that the settlor gives during the settlor's lifetime to a beneficiary of the trust is an advancement against the beneficiary's share of the trust only if either the settlor makes a written statement that the property constitutes an advancement or the beneficiary makes a written statement acknowledging that the property constitutes an advancement. For purposes of applying the property against the beneficiary's share of the trust, the property must be valued as of the time the beneficiary takes possession or enjoyment of the property, or as of the time of death of the settlor, whichever occurs first.
