Faxing to King County Superior Court — FAQ
Label each page with the case number and the party names. Note the target division — civil, family, probate, or records — on the cover sheet. That routing detail is what lets the clerk reconnect the documents if they separate. Check the details once before you send so nothing bounces back.
For most filings, no — the court requires electronic filing. The Superior Court generally requires the court's official e-filing system for case filings, so a fax is for copies, records, or correspondence. Ask the division directly so you do not send to a line that no longer takes filings.
King County Superior Court receives faxes at any hour, but the clerk's office processes them on a set schedule. Processing generally runs Monday through Friday during business hours. Send routine requests early in the day for same-day handling.
Faxing to King County Superior Court is fine as long as the channel is encrypted. A consumer app or a shared office machine is a weak place for documents like these. Send FAX Mail sends from your phone or computer over an encrypted connection starting at $12.99/month for faxes to King County Superior Court. Handled that way, the document stays protected end to end.
In most courts a new civil case and its motions are e-filed through the court's official e-filing system, not faxed. Get the civil division's line from the clerk before a deadline. Keep the confirmation until the clerk acknowledges the filing. Name the clerk's division on the cover sheet so it is not misrouted. It is a small step that saves a follow-up call later.
