1. Understanding Service of Process

Service of process is a legal procedure that ensures all parties in a court case receive proper notification. In Washington, this must be done in compliance with state laws, including those outlined in Washington Civil Rule 4. Improper service can lead to delays, increased costs, and even the dismissal of your case.


2. Grounds to Contest Service


  •  Improper Delivery If the papers were not delivered in accordance with Washington State laws (or the laws of the papers' state of origin), you may have grounds to contest the service. Examples of improper service include delivering the documents to the wrong person, leaving them with a young child, posting them on a gate or other location without court authorization, leaving them unattended on your porch, failing to provide any required notice, or, in the most serious cases, falsely claiming that service was completed when it was not.


  • Failure to Meet Due Diligence - If the process server did not make a reasonable effort to locate or serve you, this is a valid reason to quash service. For example, if a process server makes only two attempts, one in the morning and one in the afternoon, and claims they have exercised due diligence, the court may determine that those efforts were insufficient to satisfy the legal standard for due diligence.


  • Insufficient Information - Sometimes, the documents may lack critical information, such as the server's initials, date, and time of service, which can invalidate the service in certain states.


3. How to Quash Service of Process


If you believe you have been improperly served, these steps may help you to contest the service. Be sure to consult your local court, as this post is an example of a general process and does not constitute legal advice:


  • File a Motion You’ll need to file a motion to quash service with the court. This should include your reasons for contesting the service and any supporting photos and documentation.


  • Serve the Motion - Hire a process server to serve your motion to the plaintiff or their attorney, ensuring that all parties are notified of your intent to contest.


  • Attend the Hearing Be prepared to present your case in front of a judge. Bring any evidence, such as affidavits, photos, witnesses, or examples of case law that support your claim of improper service.


  • Consult an Attorney - While it’s possible to navigate this process on your own, having legal assistance may significantly improve your chances of success.


4. Why Choose Professional Process Servers?

Improper service often occurs when process servers are inadequately trained, inexperienced, or pressured to complete a high volume of assignments quickly. Some larger process-serving companies subcontract work at very low rates. In Washington, becoming a registered process server requires only a $10 annual registration fee, so registration doesn't guarantee training, experience, or professionalism. At WA Pro Se, we understand that proper service requires diligence, attention to detail, and a thorough understanding of Washington's legal requirements.
