Different expert here - my name is ***** ***** I have a different answer.
Form 3533 is a Change of Address form NOT a Change of Name form.
Since you stated in your original question that you are changing the NAME of your corporation, you would NOT use Form 3533.
If your corporation is a Delaware corporation REGISTERED to do business in California, you will first need to file a Certificate of Foreign Corporation Amendment in Delaware.
Once you have received the filed copy of the Certificate of Foreign Corporation Amendment from Delaware, you will then file an Amended Statement by Foreign Corporations with California. There must be attached to the Amended Statement by Foreign Corporation a certificate of an authorized public official of the state or place of incorporation certifying the change of name was made in accordance with the laws of that state or place. (California Corporations Code section 2107.) Both the old and new corporate names must be set forth on the face of the certificate. A certified copy of the name change amendment does not meet California statutory requirements. Note: That certificate is not required if the corporation is filing the Amended Statement by Foreign Corporation to merely delete or change a “doing business as” name without changing the legal corporate name. Note: When changing the name of a corporation .
I hope this additional information is helpful to you.
