Oregon Revised Statutes Probate Law § 116.333

(1) The personal representative or other person who is in possession of the property of the decedent and who is required to pay the tax may withhold from any property distributable to any person interested in the estate, upon its distribution to the person, the amount of tax attributable to the interest of the person. If the property in possession of the personal representative or other person required to pay the tax and distributable to any person interested in the estate is insufficient to satisfy the proportionate amount of the tax determined to be due from the person, the personal representative or other person required to pay the tax may recover the deficiency from the person interested in the estate. If the property is not in the possession of the personal representative or the other person required to pay the tax, the personal representative or the other person required to pay the tax may recover from any person interested in the estate the amount of the tax apportioned to the person in accordance with ORS 116.303 to 116.383.

(2) If property held by the personal representative is distributed prior to final apportionment of the tax, the distributee shall provide a bond or other security for the apportionment liability in the form and amount prescribed by the personal representative.
