(1) Any part of the net estate of a decedent not effectively disposed of by the will of the decedent shall pass as provided in ORS 112.025 to 112.055.
(2) A decedent by will may expressly exclude or limit the right of an individual or class to succeed to property of the decedent passing by intestate succession. If that individual or a member of that class survives the decedent, the share of the decedent’s intestate estate to which that individual or class would have succeeded passes as if that individual or each member of that class had disclaimed that individual’s or member’s intestate share.
