Breach Of Fiduciary Duty: When Can You Sue Directors?
August 31, 2026

Business partnerships thrive on collaboration, but disagreements are inevitable. When conflicts arise between partners, how you handle them determines whether your business survives or falls apart. Understanding your options and acting strategically protects both your investment and the business itself.
A deadlock happens when two equal owners of a business cannot agree on a decision, and neither has enough votes to break the tie.
In a 50/50 partnership or corporation, every major decision requires agreement from both sides. When that agreement breaks down, nobody wins the vote. The business cannot move forward. Contracts stall. Hiring freezes. Strategic decisions sit unanswered. Meanwhile, the relationship between the partners deteriorates further with every passing week.

Partner A names a price for the business. Partner B must then either buy Partner A’s shares at that price or sell their own shares to Partner A at that same price. The result is swift and decisive. One partner exits. The other stays. The business continues.
Your agreement should answer these questions:
