No insurer who provides professional liability insurance for persons licensed under the provisions of Part 1 (commencing with Section 10000) of Division 4 of the Business and Professions Code shall exclude from coverage under that policy liability arising from the breach of the duty of the licensee arising under Article 2 (commencing with Section 2079) of Chapter 3 of Title 6 of Part 4 of Division 3 of the Civil Code. Notwithstanding the foregoing, an insurer may exclude coverage against liability arising out of a dishonest, fraudulent, criminal, or malicious act, error, or omission committed by, at the direction of, or with the knowledge of the insured.
For the purposes of this section, "professional liability insurance" means insurance against liability for damages caused by any act or omission of a real estate licensee in rendering professional services in this state.
