Many businesses operate either as sole proprietorships or as partnerships. No formal agreement is required to operate as a partnership. Most of the time a partnership is just something that evolves naturally over time. Sometimes the partners memorialize their agreement with a written agreement. Other times their agreement is verbal. Frequently disputes arise between partners where the partners are not able to resolve those disputes between themselves.
I have been involved in resolving business disputes for almost twenty years now. My approach to resolving business disputes is efficient and I am always conscientious of costs. Never underestimate the value of picking up the phone and initiating a conversation with the opposing side to a dispute. A simple conversation can frequently lead to the best possible resolution and prove to be an inexpensive approach compared to litigation.
