Corp. Code, § 2106

(a) Subject to the provisions of subdivision (b), upon payment of the fees required by law the Secretary of State shall file the statement and designation prescribed in Section 2105 and shall issue to the corporation a certificate of qualification stating the date of filing of said statement and designation and that the corporation is qualified to transact intrastate business, subject, however, to any licensing requirements otherwise imposed by the laws of this state.

(b) No foreign corporation having a name which would not be available pursuant to subdivision (b) of Section 201 to a new corporation organized under this division shall transact intrastate business in this state or qualify to do so under this chapter or file an amended statement and designation containing such name unless either: (1) it obtains and files an order from a court of competent jurisdiction permanently enjoining the other corporation having a conflicting name from doing business in this state under that name; or (2) the Secretary of State finds, upon proof by affidavit or otherwise as the Secretary of State may determine, that the business to be conducted in this state by the foreign corporation is not the same as or similar to the business being conducted by the corporation (or to be conducted by the proposed corporation) with whose name it may conflict and that the public is not likely to be deceived, and the foreign corporation agrees that it will transact business in this state under an alternate name disclosed to the Secretary of State and that it will use the alternate name in all of its dealings with the Secretary of State and in the conduct of its affairs in this state. The alternate name may be its name with the addition of some distinguishing word or words acceptable to the Secretary of State or a name available for the name of a domestic corporation pursuant to subdivision (b) of Section 201. A corporation which has made such an agreement with the Secretary of State shall not do business in this state except under the name agreed upon, so long as the agreement remains in effect.

This subdivision shall not apply to any corporation that is subject to the Insurance Code as an insurer unless the insurer has first obtained from the Insurance Commissioner a certificate approving the alternate name.
