2023 District of Columbia Code › Title 28 - Commercial Instruments and Transactions. [Enacted title] › Subtitle I - Uniform Commercial Code › Article 9 - Secured Transactions › Part III - Perfection and Priority › Subpart 3 - Priority › § 28:9–335. Accessions

§ 28:9–335. Accessions.
(a) A security interest may be created in an accession and continues in collateral that becomes an accession.
(b) If a security interest is perfected when the collateral becomes an accession, the security interest remains perfected in the collateral.
(c) Except as otherwise provided in subsection (d), the other provisions of this part determine the priority of a security interest in an accession.
(d) A security interest in an accession is subordinate to a security interest in the whole which is perfected by compliance with the requirements of a certificate-of-title statute under § 28:9-311(b).
(e) After default, subject to Part 6, a secured party may remove an accession from other goods if the security interest in the accession has priority over the claims of every person having an interest in the whole.
(f) A secured party that removes an accession from other goods under subsection (e) shall promptly reimburse any holder of a security interest or other lien on, or owner of, the whole or of the other goods, other than the debtor, for the cost of repair of any physical injury to the whole or the other goods. The secured party need not reimburse the holder or owner for any diminution in value of the whole or the other goods caused by the absence of the accession removed or by any necessity for replacing it. A person entitled to reimbursement may refuse permission to remove until the secured party gives adequate assurance for the performance of the obligation to reimburse.

Uniform Commercial Code Comment
1. Source. Former Section 9-314.
2. “Accession.” This section applies to an “accession,” as defined in Section 9-102, regardless of the cost or difficulty of removing the accession from the other goods, and regardless of whether the original goods have come to form an integral part of the other goods. This section does not apply to goods whose identity has been lost. Goods of that kind are “commingled goods” governed by Section 9-336. Neither this section nor the following one addresses the case of collateral that changes form without the addition of other goods.
3. “Accession” vs. “Other Goods.” This section distinguishes among the “accession,” the “other goods,” and the “whole.” The last term refers to the combination of the “accession” and the “other goods.” If one person’s collateral becomes physically united with another person’s collateral, each is an “accession.”
Example 1: SP-1 holds a security interest in the debtor’s tractors (which are not subject to a certificate-of-title statute), and SP-2 holds a security interest in a particular tractor engine. The engine is installed in a tractor. From the perspective of SP-1, the tractor becomes an “accession” and the engine is the “other goods.” From the perspective of SP-2, the engine is the “accession” and the tractor is the “other goods.” The completed tractor-tractor cum engine-constitutes the “whole.”
4. Scope. This section governs only a few issues concerning accessions. Subsection (a) contains rules governing continuation of a security interest in an accession. Subsection (b) contains a rule governing continued perfection of a security interest in goods that become an accession. Subsection (d) contains a special priority rule governing accessions that become part of a whole covered by a certificate of title. Subsections (e) and (f) govern enforcement of a security interest in an accession.
5. Matters Left to Other Provisions of This Article: Attachment and Perfection. Other provisions of this Article often govern accession-related issues. For example, this section does not address whether a secured party acquires a security interest in the whole if its collateral becomes an accession. Normally this will turn on the description of the collateral in the security agreement.
Example 2: Debtor owns a computer subject to a perfected security interest in favor of SP-1. Debtor acquires memory and installs it in the computer. Whether SP-1’s security interest attaches to the memory depends on whether the security agreement covers it.
Similarly, this section does not determine whether perfection against collateral that becomes an accession is effective to perfect a security interest in the whole. Other provisions of this Article, including the requirements for indicating the collateral covered by a financing statement, resolve that question.
6. Matters Left to Other Provisions of This Article: Priority. With one exception, concerning goods covered by a certificate of title (see subsection (d)), the other provisions of this Part, including the rules governing purchase-money security interests, determine the priority of most security interests in an accession, including the relative priority of a security interest in an accession and a security interest in the whole. See subsection (c).
Example 3: Debtor owns an office computer subject to a security interest in favor of SP-1. Debtor acquires memory and grants a perfected security interest in the memory to SP-2. Debtor installs the memory in the computer, at which time (one assumes) SP-1’s security interest attaches to the memory. The first-to-file-or-perfect rule of Section 9-322 governs priority in the memory. If, however, SP-2’s security interest is a purchase-money security interest, Section 9-324(a) would afford priority in the memory to SP-2, regardless of which security interest was perfected first.
7. Goods Covered by Certificate of Title. This section does govern the priority of a security interest in an accession that is or becomes part of a whole that is subject to a security interest perfected by compliance with a certificate-of-title statute. Subsection (d) provides that a security interest in the whole, perfected by compliance with a certificate-of-title statute, takes priority over a security interest in the accession. It enables a secured party to rely upon a certificate of title without having to check the UCC files to determine whether any components of the collateral may be encumbered. The subsection imposes a corresponding risk upon those who finance goods that may become part of goods covered by a certificate of title. In doing so, it reverses the priority that appeared reasonable to most pre-UCC courts.
Example 4: Debtor owns an automobile subject to a security interest in favor of SP-1. The security interest is perfected by notation on the certificate of title. Debtor buys tires subject to a perfected-by-filing purchase-money security interest in favor of SP-2 and mounts the tires on the automobile’s wheels. If the security interest in the automobile attaches to the tires, then SP-1 acquires priority over SP-2. The same result would obtain if SP-1’s security interest attached to the automobile and was perfected after the tires had been mounted on the wheels.
