(a) Except as otherwise provided in subsection (b) of this section, communication of a record to a filing office and tender of the filing fee or acceptance of the record by the filing office constitutes filing. In the case of the recording of a record in a filing office described in subdivision (1) of subsection (a) of § 42a-9-501, tender of the filing fee means tender of the fee specified in § 7-34a.

(b) Filing does not occur with respect to a record that a filing office refuses to accept because:

(1) The record is not communicated by a method or medium of communication authorized by the filing office;

(2) An amount equal to or greater than the applicable filing fee is not tendered;

(3) The filing office is unable to index the record because:

(A) In the case of an initial financing statement, the record does not provide a name for the debtor;

(B) In the case of an amendment or information statement, the record:

(i) Does not identify the initial financing statement as required by § 42a-9-512 or 42a-9-518, as applicable; or

(ii) Identifies an initial financing statement whose effectiveness has lapsed under § 42a-9-515; or

(C) In the case of an initial financing statement that provides the name of a debtor identified as an individual or an amendment that provides a name of a debtor identified as an individual which was not previously provided in the financing statement to which the record relates, the record does not identify the debtor’s surname;

(4) In the case of an initial financing statement or an amendment that adds a secured party of record, the record does not provide a name and mailing address for the secured party of record;

(5) In the case of an initial financing statement or an amendment that provides a name of a debtor which was not previously provided in the financing statement to which the amendment relates, the record does not:

(A) Provide a mailing address for the debtor; or

(B) Indicate whether the name provided as the name of the debtor is the name of an individual or an organization;

(6) In the case of an assignment reflected in an initial financing statement under subsection (a) of § 42a-9-514 or an amendment filed under subsection (b) of § 42a-9-514, the record does not provide a name and mailing address for the assignee; or

(7) In the case of a continuation statement, the record is not filed within the six-month period prescribed by subsection (d) of § 42a-9-515.

(c) For purposes of subsection (b) of this section:

(1) A record does not provide information if the filing office is unable to read or decipher the information; and

(2) A record that does not indicate that it is an amendment or identify an initial financing statement to which it relates, as required by § 42a-9-512, 42a-9-514 or 42a-9-518, is an initial financing statement.

(d) A record that is communicated to the filing office with tender of the filing fee, but which the filing office refuses to accept for a reason other than one set forth in subsection (b) of this section, is effective as a filed record except as against a purchaser of the collateral which gives value in reasonable reliance upon the absence of the record from the files.
