It is common in estate disputes to encounter a party attempting to deal inappropriately with the affairs of a limited company whose shares should be an estate asset, and when this occurs, one should look for a breach of the directors fiduciary duty owed to the company.
The fiduciary duty of a director to the company is one of loyalty ,good faith, avoidance of conflict of duty and self-interest.
The leading case in this area is Canadian Aero Services Ltd v O’Malley 1974 SCR 592 where the court found senior management who had left the plaintiff with confidential information were fiduciaries and that duty continued after their employment ceased.
