2. General Rule. This Article uses the term "attach" to describe the point at which property becomes subject to a security interest. The requisites for attachment are stated in Section 9-203 [Maine cite section 9-1203]. When it attaches, a security interest may be either perfected or unperfected. "Perfected" means that the security interest has attached and the secured party has taken all the steps required by this Article as specified in Sections 9-310 to 9-316 [Maine cite sections 9-1310 through 9-1316]. A perfected security interest may still be or become subordinate to other interests. See, e.g., Sections 9- 320, 9-322 [Maine cite section 9-1320, section 9-1322]. However, in general, after perfection the secured party is protected against creditors and transferees of the debtor and, in particular, against any representative of creditors in insolvency proceedings instituted by or against the debtor. See, e.g., Section 9-317 [Maine cite section 9-1317].
