Washington Probate Cost: Filing Fees, Attorney Fees, and What to Expect

When an executor in Washington asks "how much does probate cost?" they are usually asking about the court filing fee. But that $290 fee is only a fraction of what probate actually costs. Here is an honest breakdown of every cost category, what drives each one higher or lower, and where Washington's nonintervention system can save you significant money.

Court Filing Fees

The base fee to open a probate proceeding in Washington Superior Court is $290. This covers the initial Petition for Probate and the issuance of Letters Testamentary or Letters of Administration. If you are filing in a probate-heavy county like King or Pierce, expect this fee to be uniform — Washington standardized these fees statewide.

Additional court costs to budget for:

• Certified copies of Letters Testamentary: $5 to $10 per copy. Order eight to ten at the time of issue.
• Will filing fee (if filed separately as "Will Only" without opening probate): $20.
• Declaration of Completion of Probate: Filed at the close of the estate, typically no additional filing fee beyond the initial $290.
• Document recording fees at the county auditor: Approximately $303.50 for the first page of any deed or recorded affidavit, plus $1.00 per additional page.

So the baseline court cost for a straightforward Washington probate is roughly $300 to $450 in government fees, not counting any document preparation costs.

Attorney Fees

Washington does not cap or schedule attorney fees for probate the way California does. Attorneys charge on a variety of structures:

• Flat fee for simple probates: $1,500 to $4,000 for a straightforward, uncontested estate with a will, no tax return required, and one or two assets.
• Hourly billing: $300 to $450 per hour for a probate attorney in Seattle or other major metros; $200 to $300 per hour in smaller counties.
• Percentage-based informal arrangements: Some attorneys quote a percentage of the estate (commonly 1% to 3%), though this is not mandated by Washington statute.

For a complex estate — one with business interests, real estate in multiple counties, a Washington Estate Tax Return to file, or family disputes — attorney fees routinely reach $10,000 to $25,000 or more.

The good news: Washington's nonintervention powers substantially reduce attorney involvement. Once nonintervention powers are granted at the opening of probate, the Personal Representative can manage the entire estate without returning to court. An attorney is typically needed only for the opening petition and the final Declaration of Completion. Many families handle everything in between themselves, reducing legal fees to $2,000 to $5,000 even for moderately complex estates.

Notice to Creditors Publication Cost

To reduce the creditor claim window from 24 months to 4 months, Washington Personal Representatives should publish a Notice to Creditors in a county legal newspaper. This is not strictly mandatory, but failing to publish it leaves the estate exposed to creditor claims for two years after the date of death — which is a serious problem if you want to distribute assets and close the estate promptly.

Publication costs vary by newspaper and county. Expect $150 to $400 for the required notice publication.

Accounting and CPA Fees

If the estate generates income during administration — from rental properties, dividends, interest, or the liquidation of appreciated assets — a federal Form 1041 (Fiduciary Income Tax Return) must be filed for any year in which the estate earns more than $600.

Washington CPAs charge $700 to $1,500 to prepare a federal Form 1041, more if it involves complex capital gains calculations or pass-through entity income.

If the estate is large enough to require a Washington State Estate and Transfer Tax Return (gross estate above $3,000,000), professional CPA preparation typically runs $2,500 to $5,000 or more, particularly when appraisals, QFOBI deduction calculations, or the Spousal Personal Residence Exclusion are involved.

Appraisal Fees

Washington requires credible, defensible valuations for certain estate assets. The Department of Revenue will scrutinize reported values if the estate approaches the $3,000,000 state estate tax threshold. Real estate must be valued as of the date of death, not as of when the estate finally gets around to selling.

• Residential real estate appraisal: $400 to $800
• Commercial real estate or business appraisal: $2,000 to $10,000+
• Personal property appraisal (vehicles, art, jewelry, collectibles): $100 to $500 per item category

For estates well below the estate tax threshold and without contested assets, formal appraisals may not be necessary, and a written statement of fair market value from a qualified source (such as a Kelley Blue Book printout for vehicles) may suffice.

Washington State Estate Tax

For estates exceeding $3,000,000 in gross value (as of July 1, 2026), the Washington estate tax is the largest single cost. The tax uses a graduated rate schedule starting at 10% on the first $1,000,000 of taxable estate, rising through multiple brackets. Prior to July 1, 2026, the maximum rate reached 35% on the largest taxable brackets; after that date, rates compress to a maximum of 20%.

The taxable estate is calculated after subtracting allowable deductions — the marital deduction, funeral expenses, administrative expenses, mortgages, and any Qualified Family-Owned Business Interest (QFOBI) deduction. Even so, for an estate worth $4,000,000 with no special deductions, the Washington estate tax can easily reach $150,000 to $200,000.

This tax is due nine months after the date of death. If you cannot pay in full by then, you must request an extension to file and make an estimated tax payment — the extension does not pause interest accrual on unpaid tax.

Total Cost Estimates by Estate Size

What Can Reduce Washington Probate Costs

Use the Small Estate Affidavit when eligible. If the total probate assets are under $100,000 and no real estate is involved, Washington allows successors to claim assets using a Small Estate Affidavit under RCW 11.62.010, 40 days after death. This bypasses probate entirely.

Request nonintervention powers. This single step removes the court from routine estate management and reduces the number of attorney hours needed by potentially thousands of dollars.

Front-load the creditor notification process. Publishing Notice to Creditors early starts the four-month clock running. Letting this slip adds months to the overall timeline and accumulates carrying costs on estate assets.

Organize documents before your first CPA meeting. Washington CPAs charge by the hour. Walking in with a disorganized box of papers is expensive. An organized asset inventory, copies of all account statements as of the date of death, and a list of known creditors allows your CPA to focus on filing the return, not reconstructing the estate.
