National form of financing statement and related forms. Section 9-521 [Maine cite section 9-1521] provides for uniform, national written forms of financing statements and related written records that must be accepted by a filing office that accepts written records.

i. Default and Enforcement. Part 6 of Article 9 [Maine cite Article 9-A] extensively revises former Part 5. Provisions relating to enforcement of consumer-goods transactions and consumer transactions are discussed in Comment 4.j.

Debtor, secondary obligor; waiver. Section 9-602 [Maine cite section 9-1602] clarifies the identity of persons who have rights and persons to whom a secured party owes specified duties under Part 6. Under that section, the rights and duties are enjoyed by and run to the "debtor," defined in Section 9-102 [Maine cite section 9-1102] to mean any person with a non-lien property interest in collateral, and to any "obligor." However, with one exception (Section 9-616 [Maine cite section 9-1616], as it relates to a consumer obligor), the rights and duties concerned affect non-debtor obligors only if they are "secondary obligors." "Secondary obligor" is defined in Section 9-102 [Maine cite section 9-1102] to include one who is secondarily obligated on the secured obligation, e.g., a guarantor, or one who has a right of recourse against the debtor or another obligor with respect to an obligation secured by collateral. However, under Section 9- 628 [Maine cite section 9-1628], the secured party is relieved from any duty or liability to any person unless the secured party knows that the person is a debtor or obligor. Resolving an issue on which courts disagreed under former Article 9, this Article generally prohibits waiver by a secondary obligor of its rights and a secured party's duties under Part 6. See Section 9-602 [Maine cite section 9-1602]. However, Section 9-624 [Maine cite section 9-1624] permits a secondary obligor or debtor to waive the right to notification of disposition of collateral and, in a non-consumer transaction, the right to redeem collateral, if the secondary obligor or debtor agrees to do so after default.

Rights of collection and enforcement of collateral. Section 9-607 [Maine cite section 9-1607] explains in greater detail than former 9-502 the rights of a secured party who seeks to collect or enforce collateral, including accounts, chattel paper, and
