What liability can equity impose on a lawyer for a client's breach of fiduciary duty?

• A. Vicarious liability
• B. Direct liability
• C. Criminal liability
• D. Accessorial liability

Answer: (D)

Equity can hold a lawyer liable as an accessory for a client’s breach of fiduciary duty. If a lawyer knowingly assists, counsels, or procures the breach—behaving with knowledge that the client is acting improper—they become financially responsible for the wrong. This is known as accessorial liability: it targets those who help or enable fiduciary misconduct, not the fiduciary themselves.

This differs from vicarious liability, which concerns being responsible for another’s actions in certain relationships (like employer-employee) and isn’t the usual framework for a lawyer who simply assists a client’s breach. Direct liability would be for the lawyer’s own breach, which isn’t the situation described. Criminal liability would require a separate criminal element, which isn’t the focus when discussing civil equity for assisting a breach.

So the best answer is accessorial liability because it captures the lawyer’s potential liability for knowingly aiding a client’s fiduciary breach.
