(2) Except to the extent that a fiduciary’s right to disclaim is expressly restricted or limited by another statute of this state or by the instrument creating the fiduciary relationship, a fiduciary may disclaim, in whole or part, any interest in property or power over property, including a power of appointment, without regard to whether the fiduciary is acting in a personal or representative capacity. A fiduciary may disclaim the interest or power even if the creator of the interest or power imposed a spendthrift provision or similar restriction on transfer or a restriction or limitation on the right to disclaim, or an instrument other than the instrument that created the fiduciary relationship imposed a restriction or limitation on the right to disclaim.
(3) To be effective, a disclaimer must:
(a) Be in writing or otherwise recorded by inscription on a tangible medium or by storage in an electronic or other medium in a manner that allows the disclaimer to be retrieved in perceivable form;
(b) Declare that the person disclaims the interest in the property or in the power;
(c) Describe the interest in property or power over property that is disclaimed;
(d) Be signed by the person making the disclaimer; and
(e) Be delivered or filed in the manner provided in ORS 105.642.
(4) A partial disclaimer may be expressed as a fraction, percentage, monetary amount, term of years, limitation of a power or as any other interest or estate in the property.
(5) A disclaimer is irrevocable when the disclaimer is delivered or filed pursuant to ORS 105.642 or when the disclaimer becomes effective as provided in ORS 105.633 to 105.641, whichever occurs later.
(6) A disclaimer made under ORS 105.623 to 105.649 is not a transfer, assignment or release. [2001 c.245 §5]
