Section 9--520. Acceptance and Refusal to Accept Record.
    (a) Mandatory  refusal  to accept record. A filing office shall refuse
  to accept a record  for  filing  for  a  reason  set  forth  in  Section
  9--516(b) and may refuse to accept a record for filing only for a reason
  set forth in Section 9--516(b).
    (b) Communication  concerning  refusal.  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  must  be  made  at  the  time and in the manner
  prescribed by filing-office rule but, in the case  of  a  filing  office
  described  in  Section  9--501(a)(2), in no event more than two business
  days after the filing office receives the record.
    (c) When  filed  financing  statement  effective.  A  filed  financing
  statement satisfying Section 9--502(a) and (b) is effective, even if the
  filing  office  is  required  to  refuse  to  accept it for filing under
  subsection (a). However, Section 9--338 applies  to  a  filed  financing
  statement  providing information described in Section 9--516(b)(5) which
  is incorrect at the time the financing statement is filed.
