Key Statutory Takeaways for Washington Litigants
- Under Washington General Rule 13 (GR 13) and the Uniform Unsworn Declarations Act (Chapter 5.50 RCW), an unsworn Declaration Under Penalty of Perjury under the laws of the State of Washington has the exact same legal validity as a notarized affidavit.
- Under CR 4(g) and RCW 18.180.030, any person who serves process for a fee in Washington MUST include their county auditor process server registration number and county of registration on the Return of Service.
- Every Return of Service must explicitly state the date, time, exact physical address (or manner) of service, the specific title of each document served, and the name/relationship of the person who received delivery.
- Under CR 4(g)(7), while failure to make proof of service does not affect the validity of the service itself, no default judgment will be entered by a Washington court clerk or commissioner until a compliant Proof of Service is filed.
What Must Be Included on a Washington Return of Service Under CR 4(g)
After a summons, complaint, subpoena, or notice is served, the court has no way of knowing it acquired personal jurisdiction over the defendant until a formal Proof of Service—also called a Return of Service, Affidavit of Service, or Declaration of Service—is filed in the court record. Under Washington Superior Court Civil Rule CR 4(g) (and District Court Civil Rule CRRLJ 4(g)), when service is made by any person other than the sheriff, proof of service is made by the server's affidavit or declaration.
Under CR 4(g)(6), every Return of Service in Washington must clearly state the time, place, and manner of service. In practice, Superior Court clerks and ex parte commissioners scrutinize five core elements before signing an Order of Default under CR 55: (1) the exact title of every document served (matching the filed pleadings verbatim), (2) the full name of the party served and the person who physically accepted the documents, (3) if substitute abode service was used under RCW 4.28.080(16), specific facts confirming the recipient was of suitable age and discretion AND then resident at the defendant's house of usual abode, (4) the exact date, time, and street address of delivery, and (5) the server's qualification (over 18, not a party to the action) and RCW 18.180 registration details.
Unsworn Declarations Under GR 13 & RCW 5.50 vs. Notarized Affidavits
Do Proofs of Service filed in Washington state courts need to be notarized? No! Under Washington Court General Rule 13 (GR 13) and the Uniform Unsworn Declarations Act (Chapter 5.50 RCW, formerly RCW 9A.72.085), whenever any Washington statute or court rule requires or permits a matter to be supported by a sworn written declaration, verification, certificate, or affidavit, the matter may with like force and effect be supported by an unsworn written declaration.
To be legally valid under GR 13(a) and RCW 5.50.050, the declaration must be subscribed by the process server and state substantially the following statutory certification above the signature line: "I declare under penalty of perjury under the laws of the State of Washington that the foregoing is true and correct." Crucially, GR 13 requires the declaration to state both the DATE and the PLACE (City and State) of execution! Omitting the city and state where the server signed the declaration is one of the most common technical reasons Washington judges strike defective declarations.
The Mandatory RCW 18.180 Registration Number Rule
If a process server serves legal papers for a fee in the State of Washington, Chapter 18.180 RCW imposes a mandatory disclosure requirement on the Return of Service. Under RCW 18.180.030 and CR 4(g)(2), the process server MUST list their county auditor registration number and their county of registration on the proof of service.
What happens if a paid server forgets to put their RCW 18.180 registration number on the Return of Service? First, under RCW 18.180.040(2), the party who hired the unregistered server cannot collect the process server fee as a recoverable court cost under RCW 4.84.090. Second, opposing counsel may use the omission to challenge the credibility of the return. Every Declaration of Service issued by Pacific NW Process Serving includes the server's active Washington county auditor registration number, county of registration, and itemized fee.
E-Filing Proofs of Service in King County (KCSC) and Odyssey Portal Counties
Once our process server executes the Declaration of Service, you immediately receive a high-resolution, court-ready PDF via email. How is it filed? Washington Superior Courts use two primary electronic filing ecosystems:
• King County Superior Court (Seattle & Kent/MRJC): Uses its own standalone Clerk's eFiling Application (KC Script Portal). Proofs of Service are e-filed under the "Affidavit / Declaration of Service" filing code. • Odyssey File & Serve Counties: Most other large Washington counties—including Thurston, Spokane, Clark, Kitsap, Whatcom, Benton, and Skagit (with Pierce County operating its LINX e-filing portal and Snohomish County operating Odyssey)—accept electronic PDF filings.
If you need our court runner team to e-file or physically file the original Proof of Service directly with the Superior or District Court Clerk, you can add court filing to any service order.
Frequently Asked Questions: Proof of Service & GR 13 Declarations
What if my lawsuit is filed in an out-of-state court (like New York, Florida, or Texas) that requires a wet-ink notarized Affidavit of Service?
While Washington courts accept unsworn GR 13 declarations under penalty of perjury, many out-of-state courts require a traditional notarized Affidavit of Service. Just note your out-of-state court on the Order form, and we will execute a fully notarized Affidavit of Service.
Does your Proof of Service include a physical description of the person served?
Yes. Every personal and substitute abode Proof of Service we issue includes the recipient's approximate age, gender, ethnicity, height, weight, hair color, and any distinguishing features, along with GPS coordinates of the serve.
How fast do I receive my signed Declaration of Service after the papers are served?
In most cases, your signed GR 13 Declaration of Service PDF is generated and emailed to you the same day or within 24 hours of completed field service.
