Colorado Code
Part 3 - Perfection and Priority
§ 4-9-310. When Filing Required to Perfect Security Interest or Agricultural Lien - Security Interests and Agricultural Liens to Which Filing Provisions Do Not Apply

Source: L. 2001: Entire article R&RE, p. 1348, § 1, effective July 1. L. 2006: (b)(5) and (b)(8) amended, p. 501, § 38, effective September 1.
Editor's note: This section is similar to former § 4-9-302 as it existed prior to 2001.

Example 1: Buyer buys goods from Seller, who retains a security interest in them. After Seller perfects the security interest by filing, Seller assigns the perfected security interest to X. The security interest, in X's hands and without further steps on X's part, continues perfected against Buyer's transferees and creditors.
Example 2: Dealer creates a security interest in specific equipment in favor of Lender. After Lender perfects the security interest in the equipment by filing, Lender assigns the chattel paper (which includes the perfected security interest in Dealer's equipment) to X. The security interest in the equipment, in X's hands and without further steps on X's part, continues perfected against Dealer's transferees and creditors. However, regardless of whether Lender made the assignment to secure Lender's obligation to X or whether the assignment was an outright sale of the chattel paper, the assignment creates a security interest in the chattel paper in favor of X. Accordingly, X must take whatever steps may be required for perfection in order to be protected against Lender's transferees and creditors with respect to the chattel paper.
Subsection (c) applies not only to an assignment of a security interest perfected by filing but also to an assignment of a security interest perfected by a method other than by filing, such as by control or by possession. Although subsection (c) addresses explicitly only the absence of an additional filing requirement, the same result normally will follow in the case of an assignment of a security interest perfected by a method other than by filing. For example, as long as possession of collateral is maintained by an assignee or by the assignor or another person on behalf of the assignee, no further perfection steps need be taken on account of the assignment to continue perfection as against creditors and transferees of the original debtor. Of course, additional action may be required for perfection of the assignee's interest as against creditors and transferees of the assignor .
Similarly, subsection (c) applies to the assignment of a security interest perfected by compliance with a statute, regulation, or treaty under Section 9-311(b), such as a certificate-of-title statute. Unless the statute expressly provides to the contrary, the security interest will remain perfected against creditors of and transferees from the original debtor, even if the assignee takes no action to cause the certificate of title to reflect the assignment or to cause its name to appear on the certificate of title. See PEB Commentary No. 12, which discusses this issue under former Section 9-302(3). Compliance with the statute is "equivalent to filing" under Section 9-311(b).
