# Lien Filing Improvements

> Sep 29, 2026

Several improvements to [Lien Filing](/docs/lien-filing-1):

* **Preview before you file.** `GET /lien_submissions/{filing_id}/preview_document` returns a PDF of your draft on the official UCC-1 or UCC-3 form, watermarked "PREVIEW — NOT FILED". The console shows it on the review step.
* **Download what was submitted.** `GET /lien_submissions/{filing_id}/submission_document` returns the PDF that was submitted to the state, and a new `has_submission_document` field tells you whether one is available. This applies to filings submitted from September 18, 2026 onward.
* **Filter and sort your filing history.** `GET /lien_submissions` now accepts `filed_from` / `filed_to`, `lapse_from` / `lapse_to`, `state`, `standing` (`Active`, `Lapsed`, `Terminated` or `Unknown`), `filing_type`, `action` and `secured_party`, plus `sort_by` (`updated_at`, `filing_date` or `lapse_date`) and `sort_direction`. The same filters are on the Lien Filings page in the console.
* **Filed amendments update the original lien.** When a UCC-3 is filed, the UCC-1 it amends now updates to match: a termination sets it to `Terminated`, a continuation extends its lapse date, and an assignment makes the assignee its secured party of record. The original lien fires a `LienFiling.updated` webhook when it changes, so you may see additional webhook events.
* **More you can do with imported liens.** Liens you [imported from the public record](/changelog/import-existing-liens-from-the-public-record) can now be continued and assigned, not just terminated.
* **Filing date optional on lookup.** `POST /lien_submissions/initial_filing_lookup` no longer requires a filing date. It is still required when `allow_unverified` is `true`.

No integration changes required.
