Uniform Commercial Code (UCC) Lien Filings

Most liens are filed under the Uniform Commercial Code, but the dataset also contains vessel and aircraft liens, and liens filed by the Internal Revenue Service, the Connecticut Department of Labor, and municipalities. The dataset only contains liens that are active (e.g., not lapsed) or that are less than one year past their natural lapse date.

Note that liens showing a lapse date of December 31, 9999 have no lapse date and are effective until released/terminated. These liens will remain on the data set for one year following termination/release. The source data for this dataset (Uniform Commercial Code (UCC) Lien Filings 4.0 Revised 7.2021) is business.ct.gov as of 7.2021.
