Washington Probate Cost 2026: Fees, Filing Fee, and the Small-Estate Route

Updated July 26, 2026. Quick answer: Washington sets probate compensation using “reasonable” compensation with no percentage schedule. The two numbers that decide what an estate actually pays are the fee basis and the small-estate threshold — and whether that threshold reaches real estate, which is where most published guidance goes wrong.

What probate costs in Washington

Why Washington has no single answer

Washington does not publish a percentage schedule that produces one number, so any source quoting you a firm figure is estimating. What the statute actually fixes is the standard: No percentage schedule: personal representative receives ‘such compensation as the court shall deem just and reasonable’ (RCW 11.48.210); attorney fees likewise reasonable. Nonintervention powers (RCW 11.68) keep most administrations out of court supervision. That makes three things decide the bill — how many billable hours the administration takes, whether any beneficiary contests, and whether the estate qualifies for the small-estate route below and skips most of it. Get the fee basis in writing before engaging anyone.

For states that DO publish a schedule, and to compare, use the probate cost calculator.

What is the small estate limit in Washington?

$100,000 — disposition of personal property by affidavit where the probate estate subject to probate ≤$100,000 (RCW 11.62.010); 40-day wait; personal property only. Verified.

The small-estate route here does NOT clear real estate on its own. If the person who died owned a house in their sole name, that transfer needs a separate procedure or full probate, whatever the dollar limit says. This is the single most common mistake made about small-estate affidavits, and most cost guides omit it entirely.

Full thresholds for every state: small-estate limits by state.

If the estate is still being planned rather than settled, the usual way to keep a house out of probate entirely is a living trust, which carries its own upfront cost: whether a living trust is worth it in Washington.

Does a house have to go through probate in Washington?

Usually yes, if the house was solely owned. Because Washington’s small-estate route does not clear a solely owned house, an estate that looks small on paper can still face full administration — and the fee is usually calculated on the gross value of that house, not the equity in it. That is the single most common and most costly surprise in this area, and it is fixable in advance rather than after. A fiduciary advisor can price the exposure alongside the rest of the estate picture. talk to someone about the whole estate picture.

How Washington compares to the other 50

Washington’s small-estate threshold of $100,000 ranks 7 of 50 jurisdictions with a stated figure, and sits well above the national median of $51,500. The range runs from $15,000 at the bottom to $400,000 at the top, so where an estate falls relative to the line matters far more than any national “average probate cost” figure. On fee model, Washington is one of 30 of 51 jurisdictions using the reasonable-fee approach.

Death taxes in Washington, separately

Washington levies an estate tax, one of 13 jurisdictions that do. That is a different question from probate cost and is decided by different statutes, but families routinely conflate the two.

Estate tax: yes – 2026 applicable exclusion per WA DOR tables: $3,076,000 for deaths 1/1/2026-6/30/2026, then $3,000,000 for deaths on/after 7/1/2026 (no further increases due to an expired CPI reference in statute). Rates for deaths on/after 7/1/2025: 10% to a top rate of 35% (35% on taxable amount over $9,000,000) – the highest state estate tax rate in the U.S.

What this does not include

The figures above are the probate cost — the court and compensation side of settling an estate. They are separate from any state estate tax or inheritance tax, which are taxes on the transfer itself and are owed whether or not the estate goes through probate. Appraisal, bond premium, publication, and real-estate commissions if property is sold are additional and are not set by the fee statute.

Before you hire anyone

• Ask which statute the fee is charged under, and get the citation. In Washington the governing provisions are below.
• Ask whether the quoted fee is calculated on gross value or net of debts. Gross-value states charge on the full house value even if a mortgage covers most of it.
• Ask whether the personal representative is also claiming compensation, and on what basis.
• Ask in writing whether the estate qualifies for the small-estate route, and if a solely owned house is involved, whether that route reaches it.

Washington in the rest of the picture

Probate cost is one of four things Washington decides for a retiree and their heirs. The other three — income tax on withdrawals, estate tax, and inheritance tax — are priced separately:

• Every tax Washington charges a retiree: Washington retirement taxes
