Washington State Probate Court Forms: A Complete List

Every form required to open, administer, and close a Washington State probate estate — with plain-English descriptions of what each document does.

Where to Find Washington Probate Forms

Washington State probate forms are not issued by a single central authority the way driver's license forms are. They originate from a combination of sources, and understanding where to look saves significant time at the start of the process.

The Washington Courts website at courts.wa.gov maintains a forms library that includes standardized versions of many common probate documents. These are a good starting point, but they are not always the forms your specific county requires. Most Washington Superior Courts maintain their own probate form packets, available at the courthouse clerk's office or on the county court's website.

Counties with active self-help resources — including King, Pierce, Snohomish, Spokane, and Clark — often post complete probate form sets online with filing instructions. If your county does not, a call to the probate clerk's office will usually result in a packet being emailed or mailed to you.

Always check local court rules first. King County, Pierce County, and Snohomish County each publish Local Rules that govern formatting requirements, page limits, cover sheet requirements, and electronic filing procedures. Submitting a document that does not comply with local rules can result in rejection without a hearing.

Core Probate Forms — Required in Nearly Every Estate

Form 1
Petition for Probate of Will and Appointment of Personal Representative

The document that opens the estate. Filed with the Superior Court in the county where the decedent resided. Sets out the basic facts: who died, when, where they lived, whether there is a will, who the heirs are, and who is asking to be appointed as Personal Representative. This petition must be accompanied by the original will (if one exists) and a certified copy of the death certificate.

Form 2
Order Probating Will and Appointing Personal Representative

The court order signed by the judge that formally admits the will to probate, confirms that the will is valid, and appoints the Personal Representative. This is the document you present — along with Letters Testamentary — to financial institutions to prove you have authority to act. Some counties require the petitioner to draft this order; others have a clerk or commissioner prepare it.

Form 3
Letters Testamentary

The official court-issued credential authorizing the Personal Representative to act on behalf of the estate. Banks, brokerages, title companies, the DMV, and virtually every institution will require a certified copy of the Letters before releasing assets or accepting instructions. Letters are issued after the Order is signed and typically expire after a set period (often one year) — you can usually obtain extensions if the estate remains open. In intestate cases, the equivalent document is called Letters of Administration.

Form 4
Notice to Creditors (for Publication)

A legal notice that must be published in a newspaper of general circulation in the county for three consecutive weeks after Letters are issued. The publication triggers the four-month creditor claim period under RCW 11.40.020. The notice states that an estate has been opened, identifies the Personal Representative, and directs creditors to file claims within four months of first publication. You arrange publication directly with the newspaper and receive a proof of publication affidavit when the run is complete.

Form 5
Inventory and Appraisement

A complete listing of all probate assets owned by the decedent as of the date of death, with each asset's fair market value on that date. Required to be filed with the court in most estates. Includes real estate (with the date-of-death assessed or appraised value), financial accounts, investment accounts, vehicles, personal property, and any other probate assets. For real estate and certain business interests, a formal appraisal by a licensed appraiser may be needed to support the stated value.

Form 6
Declaration of Mailing (Notice to Creditors)

A sworn declaration signed by the Personal Representative confirming that written notice was mailed to each known or reasonably ascertainable creditor of the estate. Under RCW 11.40.020, known creditors must receive individual written notice in addition to the published newspaper notice. This declaration is filed with the court as proof that the mailing requirement was satisfied. Include a list of each creditor notified and the date of mailing.

Form 7
Final Report and Petition for Distribution

The complete accounting of the estate's administration: every asset received, every expense paid, every debt satisfied, and what remains for distribution. This document also proposes how the remaining assets should be distributed among the beneficiaries and requests court approval of the distribution. In a non-intervention estate, this accounting is filed as part of the closing process. Heirs must receive notice and have an opportunity to object before distribution is ordered.

Form 8
Order of Distribution

The court order, signed by the judge, that approves the Final Report and directs the Personal Representative to distribute the remaining estate assets to the named beneficiaries in the specified amounts. Once this order is entered, the Personal Representative can make distributions and obtain receipts. Required in supervised administrations and in non-intervention estates that opt for a court-supervised closing rather than the Declaration of Completion procedure.

Form 9
Declaration of Completion of Probate

The streamlined closing mechanism available to non-intervention estates under RCW 11.68.110. Instead of seeking a formal court hearing to close the estate, the Personal Representative files a sworn declaration stating that all debts have been paid, all taxes have been filed, and the remaining assets have been distributed (or will be distributed as described). If no heir files a written objection within 30 days of receiving the Notice of Filing, the estate closes automatically — no judge required.

Form 10
Notice of Filing of Declaration of Completion

A required notice that must be mailed to all heirs and beneficiaries of the estate when the Declaration of Completion is filed. The 30-day objection period runs from the date this notice is mailed (or served). The Personal Representative must be able to prove that all required parties received this notice, so keep records of exactly when and how each notice was sent.

Situational Forms — Required Only in Certain Estates

Depending on the specific circumstances of the estate, additional forms may be required:

Situational
Petition to Sell Real Property

If the Personal Representative does not have non-intervention powers, or if a sale of real estate at a price below a certain threshold requires court approval, this petition is filed to obtain court authorization before proceeding with a sale. In non-intervention estates, real estate can typically be sold without this petition — but review local rules and the Order granting non-intervention powers to confirm the scope of authority.

Situational
Renunciation of Personal Representative / Executor

When the person named as executor in the will chooses not to serve — due to the time commitment, family conflict, or any other reason — they file a Renunciation with the court. This document formally declines the appointment and clears the way for the next eligible person (typically the alternate executor named in the will, or a beneficiary who petitions to serve) to be appointed instead.

Local cover sheet reminder: King County requires a Probate Cover Sheet attached to the front of nearly every filing. Pierce County and Snohomish County have similar requirements with their own formats. Failure to include the local cover sheet is one of the most common reasons a probate filing gets rejected at the clerk's counter. Check the local rules for your specific county before your first filing.
Pro tip: When you file the initial Petition, ask the probate clerk for the complete local form packet for the rest of the estate administration — many counties will provide a set of all subsequent forms at once. This saves multiple trips to the courthouse and ensures you have the correct local versions of each document.
