Uniform Commercial Code

The Uniform Commercial Code Section of the Division of Corporate & Consumer Services at the Department of Financial Institutions examines and files documents under the Uniform Commercial Code, including statements of business indebtedness, consignments, terminations, and financing statements and maintains the statewide Uniform Commercial Code lien system.

New Filing Rejection Policy

Beginning July 1, 2019, UCC documents that are received in a state that is unsuitable for filing with the Department shall be fully and completely reject by the Department. The Department will not ‘hold’ filings that are awaiting corrections, revisions or additional fees or information from the filer.

Any fees received that are intended for filing a rejected document will be submitted for a refund to the filer immediately and will be refunded as soon as allowable under Department policy.

Rejected filings will need to be corrected and submitted anew, along with all appropriate fees for that filing.
