# Normalized Lien Filing Type

> Mar 29, 2026

The `filing_type` field in lien filing responses is now normalized to a consistent set of values across all states. Previously, the raw value from each state's system was returned - which varied widely (e.g. `"1"`, `"UCC FINANCING STATEMENT"`, `"Original"`, `"Amendment"` depending on the state).

`filing_type` now returns a standardized value making cross-state filtering and classification reliable without custom state-by-state handling on your end.

You can read more about the enums and structure in our [Lien Search: Basics](https://docs.baselayer.com/docs/lien-search-basics.md) guide.
