Uniform Commercial Code, Article 9 — Secured Transactions

Editorial note. Article 9 was the Code's most ambitious innovation: it unified pre-Code chattel-mortgage, conditional-sale, factor's-lien, and trust-receipt regimes into a single framework governing every consensual security interest in personal property. The 1998 Revision, drafted by Reporters Steven L. Harris and Charles W. Mooney, Jr., comprehensively modernized the 1972 Official Text; the 2010 and 2022 Amendments make targeted refinements.

Editorial note. To supply a comprehensive and internally coherent law of consensual security interests in personal property and fixtures; to reduce transaction costs through a public notice-filing system; and to protect third parties who advance credit or take priority interests in reliance on public records.

Editorial note. Applies to any transaction, regardless of form, that creates a security interest in personal property or fixtures by contract (§ 9-109(a)(1)); to agricultural liens, sales of accounts, chattel paper, payment intangibles, or promissory notes; to consignments (§ 9-109(a)(4)); and to security interests arising under Articles 2, 2A, 4, and 5 (§ 9-109(a)(5), (6)).

Editorial note. Article 9 provides that a security interest attaches on satisfaction of § 9-203 (value, rights in collateral, authenticated security agreement or possession); perfects by filing, possession, or control depending on collateral type (§§ 9-308 through 9-316); and takes priority under the first-to-file-or-perfect rule (§ 9-322) and its purchase-money and fixture exceptions (§§ 9-324, 9-334).

Editorial note. Article 9 governs security interests in goods sold under Article 2 and in negotiable instruments and payment rights governed by Article 3. Section 9-334 coordinates Article 9 with the real-property law of fixtures; § 9-102(a)(41) supplies the Article 9 definition of 'fixture.' Article 12 (2022) coordinates with Article 9 on controllable electronic records.

Editorial note. Revised Article 9 (1998) expanded the scope of covered collateral, extended the reach of after-acquired property, adopted the debtor's location (rather than the collateral's location) as the general choice-of-law rule for perfection (§ 9-301), and modernized the treatment of proceeds, deposit accounts, and letter-of-credit rights.

Editorial note. Article 9 is accompanied by extensive Official Comments authored by the Reporters. The Comments to §§ 9-102, 9-203, 9-322, and 9-334 are especially important interpretive aids and are routinely cited by courts.

Editorial note. Revised Article 9 has been enacted in every U.S. jurisdiction, with Louisiana adopting a modified version. The 2010 Amendments addressed the debtor-name and filing-office rules; the 2022 Amendments add Article 12 and conforming Article 9 revisions.

Editorial note. Article 9 is heavily litigated in bankruptcy, foreclosure, and priority disputes. In re Estate of Reed (secured-party status in bankruptcy) and the many decisions interpreting § 9-334 fixture priorities illustrate the Article's central role in modern commercial and real-property litigation.

Editorial note. Article 9 is the operative regime for asset-based lending, factoring, equipment finance, mortgage-warehouse lending, and the securitization of receivables. Its coordination with real-property mortgage law (§ 9-334, § 9-604) is central to modern secured-lending practice.

Editorial note. See U.C.C. §§ 9-102 (definitions); 9-109 (scope); 9-203 (attachment); 9-301 (choice of law); 9-308 (perfection); 9-317 (interests taking priority over unperfected security interests); 9-322 (priorities among conflicting interests); 9-334 (fixtures); 9-501 (filing office); Restatement (Third) of Property: Mortgages (Am. L. Inst. 1997).

Editorial note. Every practitioner advising on collateral, foreclosure, bankruptcy, or asset-based finance must analyze the transaction under the enacted Article 9 of the governing jurisdiction. Perfection, priority, and enforcement rules are Article 9's core institutional contribution to American commercial law.
