Overview
Process Server in Washington: How Service of Process Works
In Washington, any adult who isn't a party can serve a summons under Civil Rule 4(c), but anyone who serves process for a fee must register with the auditor of the county where they live or do business under RCW 18.180. Papers can be left at the defendant's usual abode with a resident of suitable age and discretion. Timing matters: filing a complaint pauses the statute of limitations only if the defendant is served within 90 days.
Who serves process
Who Can Serve Legal Documents in Washington
Under Washington Civil Rule 4(c), service may be made by any competent adult who is not a party to the action. A plaintiff can't serve their own papers.
Anyone who serves process for a fee must be 18 or older, a Washington resident, and registered with the auditor of their county under RCW 18.180. Sheriffs, attorneys' unpaid staff, court-appointed persons and people who serve without pay are exempt. The registration number appears on the proof of service.
Typical documents include summonses and complaints, family law petitions, protection order papers, subpoenas and unlawful detainer (eviction) papers.
Proof you receive: a sworn affidavit of service
The server signs a proof of service, often a declaration under penalty of perjury, stating the date, time, place and manner of service. A registered server includes their registration number and county.

Treaties
Washington and the Hague Conventions: Treaty Status
The Hague Service Convention lets member countries send documents to each other's Central Authorities for service. Washington has not joined it, so that route isn't available, and the Convention's Article 10 rules on postal and private service don't apply. Whether those methods are acceptable depends on Washington's law and on what your court allows.
Washington is not a party to the Hague Evidence Convention, so requests for witness testimony or documents go through letters rogatory.
