Corp. Code, § 110

(a) Upon receipt of any instrument by the Secretary of State for filing pursuant to this division, if it conforms to law, it shall be filed by, and in the office of, the Secretary of State and the date of filing endorsed thereon. Except for instruments filed pursuant to Section 1502, the date of filing shall be the date the instrument is received by the Secretary of State unless the instrument provides that it is to be withheld from filing until a future date, other than instruments filed pursuant to Section 119, or, unless in the judgment of the Secretary of State, the filing is intended to be coordinated with the filing of some other corporate document which cannot be filed. The Secretary of State shall file a document as of any requested future date not more than 90 days after its receipt, including a Saturday, Sunday, or legal holiday, if the document is received in the Secretary of State’s office at least one business day prior to the requested date of filing. An instrument does not fail to conform to law because it is not accompanied by the full filing fee if the unpaid portion of the fee does not exceed the limits established by the policy of the Secretary of State for extending credit in these cases.

(b) If the Secretary of State determines that an instrument submitted for filing or otherwise submitted does not conform to law and returns it to the person submitting it, the instrument may be resubmitted accompanied by a written opinion of the member of the State Bar of California submitting the instrument, or representing the person submitting it, to the effect that the specific provision of the instrument objected to by the Secretary of State does conform to law and stating the points and authorities upon which the opinion is based. The Secretary of State shall rely, with respect to any disputed point of law (other than the application of Sections 119, 201, 2101, and 2106), upon that written opinion in determining whether the instrument conforms to law. The date of filing in that case shall be the date the instrument is received on resubmission.

(c) Any instrument filed with respect to a corporation, other than original articles or instruments filed pursuant to Section 119, may provide that it is to become effective not more than 90 days subsequent to its filing date. In case such a delayed effective date is specified, the instrument may be prevented from becoming effective by a certificate stating that by appropriate corporate action it has been revoked and is null and void, executed in the same manner as the original instrument and filed before the specified effective date. In the case of a merger agreement, the certificate revoking the earlier filing need only be executed on behalf of one of the constituent corporations. If no revocation certificate is filed, the instrument becomes effective on the date specified.

(d) Any instrument submitted to the Secretary of State for filing by a domestic corporation or a foreign corporation that is qualified to transact business in California under Section 2105 shall include the entity name and number as they exist on the Secretary of State’s records.
