9. Sales of Receivables; Consignments. Subsection (g) [Maine cite subsection (7)] provides that, except as provided in Section 9-607(c) [Maine cite section 9-1607, subsection (3)], the duties imposed on secured parties do not apply to buyers of accounts, chattel paper, payment intangibles, or promissory notes. Although denominated "secured parties," these buyers own the entire interest in the property sold and so may enforce their rights without regard to the seller ("debtor") or the seller's creditors. Likewise, a true consignor may enforce its ownership interest under other law without regard to the duties that this Part imposes on secured parties. Note, however, that Section 9- 615 [Maine cite section 9-1615] governs cases in which a consignee's secured party (other than a consignor) is enforcing a security interest that is senior to the security interest (i.e., ownership interest) of a true consignor.

§9-1602.__Waiver and variance of rights and duties

(3) Section 9-1607, subsection (3), which deals with collection and enforcement of collateral;

(5) Section 9-1608, subsection (1) and section 9-1615, subsection (4) to the extent that they require accounting for or payment of surplus proceeds of collateral;
