§ 9-601. RIGHTS AFTER DEFAULT; JUDICIAL ENFORCEMENT; CONSIGNOR OR BUYER OF ACCOUNTS, CHATTEL PAPER, PAYMENT INTANGIBLES, OR PROMISSORY NOTES.
(1) may reduce a claim to judgment, foreclose, or otherwise enforce the claim, security interest, or agricultural lien by any available judicial procedure; and
(2) if the collateral is documents, may proceed either as to the documents or as to the goods they cover.
The rights under subsections (a) and (b) are cumulative and may be exercised simultaneously.
If a secured party has reduced its claim to judgment, the lien of any levy that may be made upon the collateral by virtue of an execution based upon the judgment relates back to the earliest of:
(1) the date of perfection of the security interest or agricultural lien in the collateral;
(2) the date of filing a financing statement covering the collateral; or
(3) any date specified in a statute under which the agricultural lien was created.
A sale pursuant to an execution is a foreclosure of the security interest or agricultural lien by judicial procedure within the meaning of this section. A secured party may purchase at the sale and thereafter hold the collateral free of any other requirements of this article.
Except as otherwise provided in Section 9-607(c), this part imposes no duties upon a secured party that is a consignor or is a buyer of accounts, chattel paper, payment intangibles, or promissory notes.
