N.M. Code R. § 12.6.2.206
DATA ENTRY OF NAMES NO DESIGNATED FIELDS. A UCC document that is an initial financing statement or an amendment that adds a debtor to a financing statement and that fails to specify whether the debtor is an individual or an organization will be refused by the filing office. However, if it is accepted for filing in error, the following rules shall apply.
D. Individual names. The failure to designate the individual’s surname of an individual debtor in an initial financing statement or an amendment adding such debtor to a financing statement will cause a filing to be refused. If the filing is accepted in error, or if only the individual’s surname is designated, the following data entry rules apply.
(1) Freestanding initials. An initial in the first position of the name is treated as a first personal name. An initial in the second position of the name is treated as additional name(s) or initial(s).
(2) Combined initials and names. An initial and a name to which the initial apparently corresponds is entered into one name field only [e.g. "D. (David)" in the name "John D. (David) Rockefeller" is entered as "John" (first personal name); "D. (David)" (additional name(s) or initial(s)); "Rockefeller" (individual’s surname)].
(3) Multiple individual names on a single line. Two individual names contained in a single line are entered as two, different debtors on separate debtor lines [e.g. the debtor name "John and Mary Smith" is entered as two debtors: "John Smith", and "Mary Smith"]. Otherwise, more than one debtor in a single line will cause the filing to be refused pursuant to Subsection A of 12.6.2.28 NMAC [e.g. the debtor names "John Smith dba Smith Auto Sales"].
(4) One word names. A one word name is entered as a individual’s surname [e.g. "Cher" is treated as a individual’s surname].
(5) Nicknames. A nickname is entered in the name field together with the name preceding the nickname, or if none, then as the first personal name (e.g., "William (Bill) Jones").
