How Does Probate Work in King County, Washington?
Losing someone you love is hard enough without the confusion of legal paperwork. Not every estate in King County requires full probate. Estates valued under $100,000 may qualify for a faster path. The Superior Court accepts filings in person and online.
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.
The personal representative opens the case, gives notice to heirs and creditors, files an inventory of the estate's assets, settles outstanding debts and taxes, and then distributes the remainder under the will — or under Washington intestacy law when there is no will.
