Washington Revised Code Title 11. Probate and Trust Law § 11.68.011. Settlement without court intervention--Petition--Conditions--Exceptions

(a) The petitioning personal representative was named in the decedent's probated will as the personal representative;

(b) The decedent died intestate, the petitioning personal representative is the decedent's surviving spouse or surviving domestic partner, the decedent's estate is composed of community property only, and the decedent had no issue:  (i) Who is living or in gestation on the date of the petition;  (ii) whose identity is reasonably ascertainable on the date of the petition;  and (iii) who is not also the issue of the petitioning spouse or petitioning domestic partner;  or

(c) The personal representative was not a creditor of the decedent at the time of the decedent's death and the administration and settlement of the decedent's will or estate with nonintervention powers would be in the best interests of the decedent's beneficiaries and creditors.  However, the administration and settlement of the decedent's will or estate with nonintervention powers will be presumed to be in the beneficiaries' and creditors' best interest until a person entitled to notice under RCW 11.68.041 rebuts that presumption by coming forward with evidence that the grant of nonintervention powers would not be in the beneficiaries' or creditors' best interests.
