What is a UCC filing and why do ABL lenders require lien searches before closing?
A UCC filing is a UCC-1 financing statement that gives public notice of a security interest and perfects the lien under Article 9 (Zolvo; California SOS Form UCC1 example). ABL lenders run a lien search before initial funding to confirm priority and competing filings (OCC; UCCGuide). A UCC search alone does not reveal tax or judgment liens.

What a UCC filing is
A Zolvo UCC filing glossary says: "A UCC filing is a UCC-1 financing statement recorded with a state filing office (usually the Secretary of State) to give public notice of a lender's security interest in a borrower's collateral." The same page states that "It is the step that perfects the lien under Article 9 of the Uniform Commercial Code and establishes the lender's priority against other creditors." The California Secretary of State financing-statement page (Form UCC1 example) says: "A financing statement (Form UCC1) is filed to perfect a security interest in named collateral and establishes priority in case of debtor default or bankruptcy." Cite that as a California SOS example — not universal national filing law for every state.
Why ABL lenders require a lien search before closing
The OCC Comptroller's Handbook on Asset-Based Lending says: "To ensure the priority of the bank's lien position, the bank should conduct a lien search before the initial funding of an ABL facility and periodically thereafter." UCCGuide states that a pre-loan UCC search "reveals every active UCC-1 Financing Statement filed against a prospective borrower, tells you who their existing lenders are, what collateral is already encumbered, and where you would rank in priority if the borrower defaults." Zolvo adds: "Because of this rule, no responsible lender advances funds without first running a UCC lien search against the prospective borrower in the relevant state."
LegalClarity states that lenders run UCC searches "before extending credit or acquiring assets to confirm nothing is already encumbered," and that "Getting the debtor's name exactly right is the single most important part of a UCC search." Wolters Kluwer expert insights define a UCC search as uncovering claims or liens against personal property used as collateral and advise searching past legal names and DBAs.
What a UCC search does — and does not — show
LegalClarity UCC due diligence says: "A UCC search only reveals Article 9 financing statements. It won't show federal tax liens, judgment liens, or other encumbrances that can outrank or compete with your security interest." The same page lists the fundamental priority rule: "first to file or perfect." Wolters Kluwer says: "Searching for UCCs is only part of the picture. Should a creditor file bankruptcy, certain liabilities are paid before anyone else, including federal tax liens, state tax liens, and judgment liens." LII UCC § 9-322 states that conflicting perfected security interests "rank according to priority in time of filing or perfection."
On the ABL rail, OCC also states that the bank "needs a tickler system to alert the bank to file continuation statements for financing statements (UCC filings), which generally expire after five years," and that "The bank should also conduct periodic lien searches, particularly for higher-risk borrowers. A lien search discloses any other party that has filed a security interest in collateral."
M&A context: Glacier on who files UCC-1s
Glacier Lake Partners (M&A closing diligence) states that "Most founder-owned businesses carry UCC-1 financing statements filed by banks, equipment lessors, and factoring companies," and that "Blanket liens filed by banks on "all assets" are the most common finding; they are released at closing via a payoff letter and UCC-3 termination statement filed by the lender once the loan is retired." That is M&A payoff / release theater.
