Cowlitz County, WA Probate Information

Before you file anything with the Cowlitz County Clerk, know exactly what is in the estate. Which Washington route fits depends on whether there is a will, on who is entitled to be appointed, and on the value and type of the assets, because a full probate with letters testamentary or letters of administration, an unsupervised administration under nonintervention powers (RCW 11.68.011), and a small estate affidavit that opens no court case (RCW 11.62.010) are different routes with different filings. Those routes and their thresholds are statewide and are explained on the Washington state page. Identify the estate first so you, and if needed your attorney, file the right papers once, because the clerk's counter in Kelso stops issuing queue numbers at 4:15 p.m. and a second trip costs a day.

Identify every bank and credit union account, retirement plan, brokerage holding, life insurance policy, vehicle, and parcel of real property, along with every debt, before you file. How each asset is titled decides which route you need: the small estate affidavit reaches personal property only, while a house in Longview or Kelso, timber ground in the Toutle valley, or any other real property generally requires a probate in the superior court so that a personal representative has authority to sign a deed. Knowing the debts matters too, because nonintervention powers are granted only if the court finds the estate solvent (RCW 11.68.011). Sunset's asset discovery work, searching more than 2,300 financial institutions, exists for this step.

The Cowlitz County Clerk, the Clerk of the Superior Court, is the single probate filing office for all of Cowlitz County, at one counter in Room 233 on the second floor of the Cowlitz County Hall of Justice at 312 SW 1st Avenue in Kelso. There is no second location and no branch counter, and there is no PO Box: filings arrive at the counter or by mail to Room 233. The office serves the entire county, including Kelso, the county seat, and Longview, the county's largest city, along with Castle Rock, Kalama, and Woodland, and the unincorporated communities around them, among them Lexington, Carrolls, Silver Lake, Toutle, and Ryderwood, out to the Mount St. Helens country on the county's eastern edge. Estates from every part of the county are filed here.

Two other Cowlitz County courts sit in or near the same building and neither handles probate. Cowlitz County District Court is in Room 207 of the Hall of Justice and is a court of limited jurisdiction; it also serves as the municipal court for Castle Rock, Kalama, Kelso, Longview, and Woodland. Juvenile Court is a department of the Superior Court but sits at 1725 First Avenue in Longview. Inside the Hall of Justice the work splits between two offices: the Clerk's Office in Room 233 takes filings, fees, records requests, and ex parte submissions, while Superior Court Administration in Suite 250, at (360) 577-3085, handles scheduling, the master calendar, and remote-appearance approvals. Send the petition to the clerk and scheduling questions to Court Administration.

Washington law lets the petitioner file a probate in the superior court of any county in the state (RCW 11.96A.050(4)), but in practice you file in the county where the decedent lived: an interested party can move venue there within four months of the notice of appointment, and if the probate is filed outside the county of residence the creditor notice must still be published in the county of residence (RCW 11.40.020(2)). So if the person who died lived in Cowlitz County, file with the Cowlitz County Clerk. One narrow exception is not optional: a petitioner who seeks appointment under RCW 11.28.120(3), the route for a person not otherwise entitled that opens only after 90 days, must file where the decedent resided, or, for a nonresident, in a county where estate property is. Once letters have been granted, the rest of the probate stays in that county (RCW 11.96A.050(5)). Cowlitz recognizes the other side of that rule in its own fee schedule, which charges $20 to file a notice to creditors here when the probate itself was filed in another county and the decedent resided in this one (RCW 36.18.050, RCW 11.40.020(2)).

The first Cowlitz distinctive is that most probate orders never reach a hearing, because the court has no formal ex parte docket and the clerk presents orders for you. The Clerk's Office publishes the procedure directly: each day a judge is assigned to review and sign ex parte orders as availability allows, and the office will present your orders on your behalf if you mail or drop off the original motion and order along with the copies you want conformed and a self-addressed stamped envelope. A $30 fee is due at submission for up to three orders in one case on one day (RCW 36.18.016(12)), and a separate $30 is due for each additional case. Under CCLAR 12(1) of the local rules the assigned judicial officer reviews and decides, or asks for more information, generally by no later than the next business day, and the documents then return to the Clerk's Office. Getting paper back to you is the slower half: the clerk warns that the process may take up to a week, that the office will not search for your order or tell you when it has been signed, and that it will not pay to mail anything, so the prepaid envelope is not optional. Conforming means the clerk stamps your copy with the filed stamp, the date, the judge's name, and any changes the judge made; if you skip the fee you simply wait for the order to be processed and scanned into the case, or you prepay for certified copies instead. The Superior Court's own ex parte page adds that documents can be submitted by mail or courier and that an emergency request goes in with a cover sheet identifying it as an emergency civil order request, which routes it to a judicial assistant for immediate assignment (CCLAR 12(3)).

The second is that the probate calendar is a Zoom calendar that decides matters on paper. The court's Guardianship and Probate docket sits on Wednesdays at 1 p.m., is held by Zoom, and is streamed on the court's YouTube channel, and it is one of the dockets the court lists as needing no prior approval to attend remotely. The clerk's Civil Calendar Notice, Clerk Form 12.2025, is the form that notes a matter onto it, and the form itself carries the terms: decisions are made on the filed written documents only with proof of service filed, you must respond in writing and appear by Zoom, you may not appear in person, an email address is required so the court can send hearing notification, and you must submit proposed draft orders for the court to sign. Deadlines are real. Under CCLCR 77(k)(3) materials for a motion docket must be filed with the Clerk's Office no later than 10 a.m. at least three court days before the docket, and a hard copy must go to the assigned judge for anything filed less than seven court days out; the form repeats a three-day cutoff and warns that later filings will not be available for court review without a bench copy. The calendar rotates with the assigned department's trial weeks, so it is not on every Wednesday, and the court posts its dockets and hearing days in the Hall of Justice second-floor lobby as well as online (CCLCR 77(k)(1)). Where a probate matter does need argument, non-jury sessions run 9 a.m. to noon and 1 p.m. to 4:30 p.m. (CCLCR 77(d)(1)).

The third is a dated change to how documents arrive. The Cowlitz local rules currently published by the Administrative Office of the Courts, effective September 1, 2025, contain no electronic filing rule, and their only electronic provision, CCLGR 17, lets the clerks accept documents whose original or verifiable electronic signatures were transmitted by fax, scan, or email while expressly declining to create any ability to file with the Clerk's Office by email or other electronic means unless another rule says so. The court has since adopted LGR 30, which provides that effective September 1, 2026 attorneys shall electronically file all documents using the court's designated eFiling service unless the rule provides otherwise, while non-attorneys and self-represented parties are not required to eFile and are encouraged but not compelled to do so. Three parts of that rule matter in an estate. Documents the law requires to be filed in non-electronic format may never be eFiled, and the rule names original wills as its example, so lodging the original will stays a paper errand. Attorneys and other eFilers are relieved of providing duplicate paper working copies. And materials must be eFiled no later than noon on the day before a scheduled hearing, which is tighter than the three-court-day docket rule and does not replace it. An attorney unable to eFile may request a waiver on good cause, must file a copy of it in each case and caption paper documents as exempt, and may be charged a fee for each paper document filed without one. Confirm the designated service and the rule's current status with the Cowlitz County Clerk, because the AOC-published rule set does not yet carry LGR 30.

Two smaller local points save trips. Filing and scheduling live in different offices in the same building: the Clerk's Office in Room 233 takes petitions, fees, records requests, and ex parte submissions at (360) 577-3016, while Superior Court Administration in Suite 250 handles the master calendar, special settings, and remote-appearance approvals at (360) 577-3085. And the county's Courthouse Facilitator, who is often the first person a self-represented filer hears about, is not a probate resource: the county describes the facilitator as giving procedural and form advice to self-represented parties in family law matters, by appointment only for $20 set when the appointment is made, and CCLCR 92 requires facilitator review only of family law final pleadings. For a probate, the practical substitutes are the clerk's published procedures, the free law library terminal on the second floor, and WashingtonLawHelp.

Many Cowlitz County estates are uncontested, and a personal representative granted nonintervention powers administers and closes a solvent estate without further court supervision (RCW 11.68.011), which is why plenty of families here get through probate with limited legal help. Consider counsel when a will is contested or a dispute among heirs is likely, when the estate is insolvent or a creditor is pressing a claim, when a Trust and Estate Dispute Resolution Act proceeding is filed, when a business, timber or river-front property, or property in another state has to be valued or divided, when the estate is large enough to owe Washington estate tax under chapter 83.100 RCW, or when no one entitled to appointment has come forward and the petition has to be made under RCW 11.28.120(3). Cowlitz adds two practical reasons. From September 1, 2026 an attorney filing here must eFile under the county's LGR 30, so a lawyer already set up on the court's designated service can put documents in front of a judge without a counter trip. And because contested probate matters are decided on the written documents noted onto the Wednesday Guardianship and Probate calendar, the quality of the declarations and the proposed orders is the case. The Cowlitz County Clerk can explain procedure but is instructed not to give legal advice, and the county's Courthouse Facilitator serves family law matters only.
