A
Money owed to a business by its customers for goods or services delivered. AR is a common UCC collateral category — ABL lenders and factors take security interests in receivables as the primary collateral for revolving credit lines.
The section of the Uniform Commercial Code that governs secured transactions involving personal property. Article 9 sets the rules for creating, perfecting, and enforcing security interests — including when UCC-1s must be filed, how long they last, and what happens when they lapse.
A UCC-3 amendment that transfers the secured party's rights in a financing statement to a new secured party. Common when a lender sells its loan portfolio or a borrower's debt is acquired. After assignment, the new secured party has all the rights of the original lender.
The moment a security interest becomes enforceable against the debtor — when value is given, the debtor has rights in the collateral, and the debtor has authenticated a security agreement. Attachment creates rights against the debtor; perfection is the additional step that creates rights against third parties.
B
A UCC-1 filing with a collateral description covering "all assets," "all personal property," or similar all-encompassing language — rather than naming specific equipment or inventory. Blanket liens are common in commercial lending (SBA loans, lines of credit) and give the secured party a claim on essentially everything the debtor owns.
C
The property subject to a security interest — what the lender can claim if the borrower defaults. UCC Article 9 collateral includes equipment, inventory, accounts receivable, deposit accounts, instruments, investment property, intellectual property, and general intangibles. Real estate is not Article 9 collateral.
A UCC-3 amendment that extends a financing statement for another 5 years. Must be filed within the 6-month window before the original lapse date — not before, not after. A continuation filed outside this window is ineffective, and the original filing lapses as scheduled.
D
The party who grants a security interest in collateral — typically the borrower in a lending transaction. The debtor's name and address on the UCC-1 are critical: even minor errors in the debtor's name can render the filing "seriously misleading" and potentially unperfected under UCC 9-506.
F
The public record document filed with the Secretary of State to perfect a security interest — formally called a UCC-1 financing statement. It names the debtor, the secured party, and the collateral. It does not prove the amount owed or the existence of a valid underlying loan — it only proves that a security interest has been asserted.
A specialized UCC filing for goods that become fixtures — physically attached to real estate (HVAC systems, industrial equipment bolted to a building). Fixture filings must be made in the county where the real property is located, not only with the Secretary of State. They don't create a real estate lien but do cover the attached personal property.
G
A catch-all UCC collateral category covering intangible assets that don't fit other categories — software, trade secrets, goodwill, intellectual property rights, and similar non-physical business assets. Often included in blanket lien collateral descriptions as part of "all personal property."
L
The automatic expiration of a UCC-1 financing statement 5 years from the filing date, if no continuation is filed in time. Lapse renders the security interest unperfected — the secured party loses priority against other creditors and a bankruptcy trustee. The lien does not disappear, but it loses its enforceable position.
A broad legal concept — any legal claim on property that secures payment of a debt or performance of an obligation. Liens can be voluntary (granted by the debtor, like a mortgage or UCC security interest) or involuntary (imposed without consent, like a tax lien or judgment lien). A UCC filing creates a specific type of voluntary lien on personal property.
P
The process that makes a security interest enforceable against third parties — other creditors, lien holders, and a bankruptcy trustee. For most personal property collateral under Article 9, perfection requires filing a UCC-1 with the Secretary of State. Without perfection, the security interest loses to any later-perfected creditor and to the bankruptcy trustee.
A security interest in goods that secures the purchase price of those goods — equipment financing is a common example. PMSIs have "super-priority" under UCC 9-324: if perfected within 20 days of delivery, they take priority over a prior blanket lien on the same collateral. This is the main exception to the first-to-file priority rule.
The ordering of competing claims on the same collateral. Under UCC 9-322, the general rule is first-to-file-or-perfect wins — a lender who files a UCC-1 on Monday has priority over a lender who files on Tuesday, even if the Tuesday lender has a better claim factually. Priority determines who gets paid first when collateral is sold or liquidated.
S
The lender, creditor, or other party who holds a security interest in the debtor's collateral — listed on the UCC-1 financing statement. The secured party has the right to enforce the security interest if the debtor defaults, including repossessing and selling the collateral to satisfy the debt.
The underlying contract between the debtor and secured party that creates the security interest — signed (or "authenticated") by the debtor, granting a lien on described collateral to secure an obligation. The UCC-1 financing statement is NOT the security agreement; it's the public notice filing that perfects the security interest created by the agreement.
A property right in collateral that secures payment of a debt or performance of an obligation under UCC Article 9. The functional equivalent of a lien on personal property. Created by a security agreement, perfected by filing a UCC-1, and enforced by repossession and sale if the debtor defaults.
T
A UCC-3 amendment filed by the secured party to officially end a financing statement — typically when the underlying debt is repaid. Under UCC 9-513, the secured party must file a termination within 20 days of receiving an authenticated demand from the debtor for consumer goods, or upon the debtor's request for business collateral. Paying off a loan does not automatically terminate the UCC-1.
U
The standard form filed with the Secretary of State to perfect a security interest in personal property under Article 9 of the UCC. Lists the debtor name, secured party name, and collateral description. Effective for 5 years from the filing date unless continued by a UCC-3 Continuation filing.
A filing that modifies an existing UCC-1 financing statement. Four types: Continuation (extends for 5 more years), Termination (ends the filing), Assignment (transfers the secured party's rights to a new party), and Amendment (changes debtor name, collateral description, or other information). Each type has different rules about who can file it.
A public records search that retrieves all active UCC-1 financing statements filed against a named debtor in one or more Secretary of State databases. Lenders run UCC searches before extending credit to check priority position. Buyers run UCC searches to find liens on assets they're acquiring. A clean search result means no active UCC liens were found — not that no liens of any type exist.
W
Short-term financing used to fund day-to-day business operations — typically secured by a blanket lien on all business assets or a revolving lien on receivables and inventory. Online lenders (Kabbage, OnDeck, Fundbox) commonly file broad UCC-1s for working capital products, which can surprise business owners who didn't realize their equipment and IP were pledged as collateral.
What is a UCC filing?
A UCC filing is a public record — typically a UCC-1 financing statement — filed with the Secretary of State to perfect a secured party's security interest in a debtor's personal property. It's how a lender puts the world on notice that they have a claim on specific collateral (equipment, inventory, accounts receivable, etc.) if the borrower defaults. UCC filings are governed by Article 9 of the Uniform Commercial Code.
What does UCC stand for in the context of liens?
UCC stands for Uniform Commercial Code — a comprehensive set of laws governing commercial transactions that has been adopted (with variations) in all 50 U.S. states and D.C. In the context of liens and secured lending, "UCC" almost always refers to Article 9, which covers secured transactions involving personal property — the rules for UCC-1 filings, perfection, priority, and lapse.
How do I run a UCC lien search?
You can run a UCC search manually through each state's Secretary of State portal — free, but takes 30–60 minutes per debtor since you need to search each state where the debtor may be organized or operating. For business entities, the correct state to search is typically the state of organization (where the entity was incorporated or formed), not where it operates. LienClear automates this across all 51 jurisdictions and delivers results with AI analysis in under 5 minutes.

How long is a UCC filing valid?
A UCC-1 financing statement is effective for 5 years from the date of filing. To extend it, the secured party must file a UCC-3 Continuation within the 6-month window before the lapse date. If no continuation is filed, the financing statement lapses — the security interest becomes unperfected and loses priority against other creditors and a bankruptcy trustee.

What is the difference between a UCC-1 and a UCC-3?
A UCC-1 is the original financing statement that creates and perfects the security interest. A UCC-3 is an amendment to an existing UCC-1. There are four types of UCC-3: Continuation (extends the filing 5 years), Termination (ends it), Assignment (transfers rights to a new secured party), and Amendment (changes debtor name, collateral, or other information). Every UCC-3 must reference the file number of the original UCC-1 it's modifying.
Does a paid-off loan automatically clear a UCC lien?
No. Paying off a loan doesn't automatically trigger a UCC-3 Termination. The secured party must file a termination with the Secretary of State. Under UCC 9-513, they're required to file within 20 days of an authenticated demand from the debtor (for consumer goods) or upon the debtor's written request (for business collateral). In practice, lenders often file terminations at payoff — but delays happen. If a UCC-1 is still active after a loan is paid, the debtor should request termination in writing.

What is a "blanket lien" and why does it matter?
A blanket lien is a UCC-1 with a collateral description covering "all assets" or "all personal property" of the debtor — rather than specific items. They're common in SBA loans, lines of credit, and online business lending. A blanket lien matters because it blocks a new lender from getting first-priority position on any specific collateral — the existing lender's blanket claim takes priority over any later filing. Discovering an existing blanket lien is one of the most common outcomes of a UCC lien search.
LienClear searches UCC-1 financing statements filed with the Secretary of State in all 51 U.S. jurisdictions — all 50 states plus the District of Columbia. Enter a debtor name, select a state (or search all 51), and get a complete AI-analyzed report in under 5 minutes.
