Quick answer: the biggest delay risks in Washington are skipping the optional creditor notice, not having nonintervention powers, and real estate that needs to be sold. Estimate your own timeline with the Washington probate timeline calculator.
1. Skipping the creditor notice
2. Not having nonintervention powers
Nonintervention powers under RCW § 11.68.011 are what let a Washington personal representative act — including selling real estate — without seeking court approval for each individual step. A will that doesn't request them, or an intestate estate the court won't grant them to (often because it's contested or possibly insolvent), forces the personal representative back to court repeatedly, adding real time at multiple points in the process.
3. Real estate that needs to be sold
Even with nonintervention powers in hand, selling estate real estate adds its own appraisal, listing, and closing timeline on top of the baseline. Without those powers, the sale itself may also require separate court approval, compounding the delay.
4. A contested appointment or will
A dispute over who should serve as personal representative, or a challenge to the will itself, has to be resolved by the Superior Court before normal administration can proceed — and a genuinely contested estate is also less likely to be granted nonintervention powers in the first place, compounding the delay on two fronts at once.
