The Private Security Agreement (PSA) does not need to be filed, although it can be filed with the local county recorder if so desired, please review COURT PROTECTION SECRETS > ARTICLE III COURT FILING INSTRUCTIONS. Should the PSA be required due to a financial review or court action, the document should be scanned into a digital archive (Dropbox, Google Drive, etc.) and also kept in a safe location with all the other trust documents. For a UCC-1, filing is only required for the Pass-Through Trust having a lien on the Operating Trust(s) and/or Public Entity(ies) like an LLC, C-Corp, S-Corp, etc.
