PLEASE NOTE: Mandatory electronic filing for attorneys started July 1, 2009 (See the King County Local General Rule 30). Unrepresented parties are encouraged to e-file but are not required to do so.
You can electronically file most documents into an existing case and file a new case electronically through the e-filing application; including, paying any filing fee(s) online. The document exceptions are listed in LGR 30. E-file now here.
You can also electronically submit working copies to the judicial officer through the eFiling application for a flat fee of $20.00 per submission.
If not required to e-file, you can file all King County Superior Court documents at the Clerk’s Office. We have three office locations. If your document requires a filing fee you will need to file it with the cashiers. If your document does not have a fee you can either drop it in the rapid filing box or take it to the customer service counter for filing.
If not required to e-file, you can mail documents to the Clerk's Office be filed. If there is a filing fee please include the appropriate payment and make your envelope ATTN: Cashiers. If you would like you may include a self-addressed stamped envelope as well as a copy of your document(s) and we will stamp it received and mail it back to you along with your receipt (if applicable).
