Mandatory electronic filing for attorneys started July 1, 2009 (See King County Superior Court Local General Rule 30).  Unrepresented parties are encouraged to e-file but are not required to do so.

File Electronically

E-filing documents online is quick and easy.  Setting up an eFiling application user account is free.  Regular filing fees apply and paid with an internet check or credit card. 

To learn more, go to the Clerk's  e-filing information page

For assistance, contact the our eServices Clerk at 206-477-3000 or email:


File In-Person

If not required to e-file, you can file Superior Court case documents at any of the Clerk's three office locations (directions). 

If the document requires a filing fee, go directly to the cashiers counter. 

Documents that do not require a fee may be placed into the Clerk's filing drop box or given to the customer services clerk for filing.


File By Mail

If not required to e-file, you may mail documents to the Clerk's Office to be filed.  If a filing fee is required, include the appropriate payment and address your envelope ATTN: Cashiers. 

For a "received" stamped copy of your filed document, include a self-addressed stamped envelope and an extra copy of the document.

For assistance, call 206-296-9300 or email Customer Services.
