Estate Planning & Probate in King County, Washington

King County estate questions split two ways—planning so your family skips probate, or settling an estate that is already in it. Start with your situation below; both paths use King County's actual court and recording details.

The Probate Process in King County

Probate is the court-supervised process of settling someone's estate after they die — validating the will, paying debts and taxes, and transferring what's left to the heirs. In King County, probate runs through the Superior Court at 516 3rd Ave, Rm C-203, Seattle. King County runs probate e-filing through kingcounty.gov, the only Washington county on that system.
