17918. No person transacting business under a fictitious business name contrary to the provisions of this chapter, or his assignee, may maintain any action upon or on account of any contract made, or transaction had, in the fictitious business name in any court of this state until the fictitious business name statement has been executed, filed, and published as required by this chapter.
