Start with what you both signed
The operating agreement, shareholders agreement, or partnership agreement often contains the roadmap: buy-sell provisions, deadlock procedures, valuation formulas, mediation or arbitration requirements, and rules about who can sign checks. Many owners have not read theirs since the business started. If there is no written agreement, default rules under state law fill the gap, and those defaults may not reflect what either of you expected. The type of entity matters too, because a corporation, an LLC, and a partnership are each handled differently when owners fall out. Knowing which rules apply is usually the first step toward a realistic plan.
Protecting yourself while things are unsettled
Keep copies of documents you already have legitimate access to, such as financial statements, tax returns, and your own correspondence, and ask a lawyer before taking company files beyond that. Watch the bank accounts and tax filings, since an owner can remain exposed for obligations incurred while the dispute drags on. Avoid moves that may look like retaliation, such as locking your partner out of systems or cutting their distributions, before understanding whether you have that authority. Work through the timeline of key events with your lawyer rather than on a shared company drive. Keep dealing with customers and employees in a calm, business-as-usual way, because the value of the business is what both of you stand to lose.
Paths short of a courtroom
Many partner disputes end in a negotiated buyout, where one owner purchases the other's interest at a price set by agreement, appraisal, or a formula in the governing documents. Others end with a planned sale of the whole business, a division of clients or locations, or a revised agreement that changes roles. Mediation can help when the relationship is strained but both sides want to avoid the cost of litigation. If there is evidence of diverted money or a competing business, a faster legal response may be needed. In a first consultation we discuss your goal, whether that is staying, leaving, or winding down, and which of these paths fits the documents and the facts.
