If the filing office finds grounds under 950 CMR 140.14 to refuse acceptance of a UCC record, the filing office shall return the record to the filer and return the filing fee if paid by separate check. The filing office shall send a notice that contains the date and time the record would have been filed had it been accepted for filing (unless such date and time are stamped on the record), and a brief description of the reason for refusal to accept the record. The notice shall be sent to a secured party or the filer no later than the second business day after the filing office receives the record.
