Priority of security interests created by new debtor.

(a) Subject to Subsection (b) of this section, a security interest that is created by a new debtor in collateral in which the new debtor has or acquires rights and is perfected solely by a filed financing statement that would be ineffective to perfect the security interest but for the application of Paragraph (1) of Subsection (i) of Section 55-9-316 or Section 55-9-508 NMSA 1978 is subordinate to a security interest in the same collateral that is perfected other than by such a filed financing statement. (b) The other provisions of Sections 55-9-301 through 55-9-342 NMSA 1978 determine the priority among conflicting security interests in the same collateral perfected by filed financing statements described in Subsection (a) of this section. However, if the security agreements to which a new debtor became bound as debtor were not entered into by the same original debtor, the conflicting security interests rank according to priority in time of the new debtor having become bound.
