OPINION
Appellant based this action on fraud and breach of an agreement making him a Tuc *196 son distributor for products of Solahart, Inc. The complaint named as defendants, among others, Solahart, Inc., and Jerry Singer, Jane Doe Singer, Gene Hoffman and Jane Doe Hoffman, doing business as Solahart, Inc. Jerry Singer died during pendency of the action and his wife, Tina, filed a motion for summary judgment on the ground that the complaint failed to state a claim against her or her husband individually because any liability would extend only to the corporation. The trial court granted the motion and this appeal followed.
The pleadings, depositions and affidavits establish the following sequence of events:
1. June 29, 1977. Appellant entered into a written dealership agreement which was signed by him and Gene Hoffman on behalf of Solahart, Inc.
2. August 8. The corporation commission received the articles of incorporation of Solahart, Inc.
3. August 9. Appellant filed his complaint in this action.
4. August 11. The Solahart articles of incorporation were filed.
5. August 24. Tina Singer filed a motion for summary judgment seeking to dismiss “the subject action as against the individual defendant Singer.” The motion was granted after argument.
Appellant contends the action was improperly dismissed as to appellee because as a promoter her husband may be personally liable for all pre-incorporation agreements signed on behalf of the corporation. We agree.
In Arizona a corporation’s existence begins with the filing of the articles of incorporation. A.R.S. Sec. 10-056(A). August 11, the date on which the articles were filed, therefore marks the beginning of Solahart’s existence as a corporate entity. It is well established that a corporate structure is a separate legal entity which has the legitimate purpose of insulating individuals from personal liability for acts done on behalf of the corporation.
Dietel v. Day,
Those who take an active part in organizing the corporation prior to its coming into being are called promoters of the corporation. Unless there is a specific agreement to the contrary, promoters remain liable on their pre-incorporation contracts even after incorporation.
RKO-Stanley Warner Theaters, Inc. v. Graziano,
*197
Appellee argues that appellant is precluded from pursuing his claim against her because he failed to allege a theory of partnership liability in his complaint. The complaint names Singer and his co-promoter individually, however. If appellee was unclear as to the theory of liability, she had the option of asking for clarification.
Markel v. Transamerica Insurance Title Company,
Appellee argues that the action was properly dismissed because the complaint failed to name as an indispensable party another member of the partnership. Where partners are both jointly and severally liable, however, suit may be brought against all or any of the partners.
Brown v. Coates,
Finally, we reject appellee’s contention that appellant is barred under the doctrine of election of remedies from pursuing his claim on a partnership theory because he originally elected to sue the corporation. The doctrine of election of remedies operates to preclude a claimant from maintaining an action on one theory and then pursuing an inconsistent theory based on the same claim.
Hennesy Equipment Sales Co.
v.
Valley National Bank,
Reversed and remanded.
Notes
. A motion to amend the complaint was filed on September 16 after the filing of the articles and granted on November 21. The only amendment, however, was deletion of a count for rescission and in any event, under 16 A.R.S., Rules of Civil Procedure, Rule 15(c), the amendment relates back to the date of the original pleading and therefore still predates the articles of incorporation.
