Overview

Benton County is located in Washington with a population of approximately 218,000. The Benton County Superior Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Washington probate is governed by Title 11 of the Revised Code of Washington (RCW). The process begins with filing a Petition for Letters Testamentary (if there is a will) or Petition for Letters of Administration (if there is no will) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

Washington offers a simplified process for small estates called the Small Estate Affidavit procedure. This is available if the value of the probate estate (excluding liens and encumbrances) does not exceed $100,000, and the decedent had no real property in the state (or the real property is not part of the probate estate).

Washington does not have a statutory fee schedule for attorneys or personal representatives; fees must be "reasonable" based on the services provided.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the probate estate is valued at $100,000 or less and includes no real estate, you may be able to use a Small Estate Affidavit after a 40-day waiting period.
  • Community Property Agreement: If the decedent and spouse had a valid Community Property Agreement, assets may transfer without probate.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Letters with the Benton County Superior Court. Include:

  • Case Information Cover Sheet
  • Original Will (if applicable)
  • Certified Death Certificate
  • Filing fee (approximately $240–$290)
  • Proposed Order Appointing Personal Representative
  • Oath of Personal Representative

Benton County allows for e-filing through the Odyssey File & Serve system.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the appointment to all heirs, beneficiaries, and interested parties within 20 days of appointment.
  • Publish notice in a newspaper of general circulation in Benton County (such as the Tri-City Herald) for three successive weeks to alert creditors.

Step 4: Attend the Hearing

Many probate petitions in Washington can be handled "ex parte" (without a formal hearing) if all documents are in order. If a hearing is required, the court will schedule it upon filing. Once approved, the Clerk issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors and allow for the 4-month creditor claim period
  • Inventory and appraise all estate assets within 3 months
  • Pay valid creditor claims and administrative expenses
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • File a Declaration of Completion of Probate to close the estate

Benton County-Specific Procedures
