How to search for recorded documents

The following are instructions to help you search for your recorded documents. Please note the Records Search application performs searches by name, parcel and recording number (aka instrument number). It does not search by property address.


  1. Click on the green "Search Here" button to begin. You must accept the disclaimer on the following page to proceed to the index.

  2. Click on the appropriate database of your choice.

  3. To search by "Party Name": When searching for a document, make sure to enter full name of party (buyer, seller, giver, debtor, lender, etc…) in the “party name” field, ignoring all other fields at this point. After you click search, a list of documents that contain the party name will appear. Most people have a limited number of documents under their name, so bringing up a list of all the documents under the name will enable you to locate the one you are searching for.

  4. Refining your search by “Date Filed”. If you have a common name or you have found too many documents listed under the Party Name, you can refine your search by narrowing the date in which the document was filed. Make sure to add in the full name (last name, first name and middle initial) in the Party Name search criteria, then go to “Date Filed From” and add in the oldest date you want to search, followed by using today’s date (mm/dd/yyyy) in the “To” box.


  5. To search by “Tax Parcel”: If you know the King County Assessor’s Tax Account Number (parcel number) for a property, you can enter the first 10 digits in the “Parcel No. From” field, leaving the “To” field blank. All documents associated with this tax parcel will be listed. Keep in mind by searching by a tax parcel number will only pull up recorded documents form 1997-current. Since the online records database cannot search by address you can visit the King County's Geographical Information Systems (KCGIS) Parcel Viewer to obtain the parcel number.

  6. To search by "Instrument Number": It is helpful to know that the terms recording number and auditor’s file number are interchangeable. In addition, the first 8 numbers reflect the year, month and date a document was submitted for recording, followed by the day’s processing number. For example: recording number =19980125000355, therefore the document was recorded January 25, 1998 and it was the 355th document that was received by the office on that day.

  7. Viewing an image of the document. To view a document from your query results, the document image icon must appear on far right column. Click on the icon, choose if you prefer to download document as a PDF or TIFF, then click on the hyperlinked “view image”. To view the PDF/ TIFF image, you will need to have installed the compatible readers. If there is no option to download, the following will read as “Not scanned or not available online”.
