Cal. Commercial Code § 9520

(a) A filing office shall refuse to accept a record for filing for a reason set forth in subdivision (b) of Section 9516 and may refuse to accept a record for filing only for a reason set forth in subdivision (b) of Section 9516. (b) If a filing office refuses to accept a record for filing, it shall communicate to the person that presented the record the fact of and reason for the refusal and the date and time the record would have been filed had the filing office accepted it. The communication shall be made at the time and in the manner prescribed by filing-office rule, but in the case of a filing office described in paragraph (2) of subdivision (a) of Section 9501, in no event more than two business days after the filing office receives the record. (c) A filed financing statement satisfying subdivisions (a) and (b) of Section 9502 is effective, even if the filing office is required to refuse to accept it for filing under subdivision (a). However, Section 9338 applies to a filed financing statement providing information described in paragraph (5) of subdivision (b) of Section 9516 which is incorrect at the time the financing statement is filed. (d) If a record communicated to a filing office provides information that relates to more than one debtor, this chapter applies as to each debtor separately.
