Start with what you signed, or did not
An operating agreement, shareholders' agreement, or partnership agreement often decides more than either partner remembers, including how decisions are made, what happens when votes are split, whether one owner can force a buyout, and how an interest is valued. If nothing was signed, default rules under state law fill the gaps, and those rules may not match what the partners assumed. The type of entity matters as well, because the duties owners owe each other and the remedies available differ among partnerships, LLCs, and corporations. Reading these documents closely is usually the first step in any business partner dispute, and it often changes how each side sees its options.
Keeping the business running while you disagree
Disagreements become expensive when the business stops functioning: payroll slips, vendors go unpaid, or customers sense instability. Keep doing your job, keep a record of decisions and communications, and get advice before unilateral moves such as changing bank access, firing the other partner's allies, or moving clients, since those steps can become the basis for claims against you. Hold on to your own emails and messages, but ask before copying company files to a personal account. Ownership records, tax returns, bank statements, and any written understandings, even informal ones, help clarify where each person stands.
Paths short of litigation
Many partner disputes end in a negotiated buyout, a reshuffling of roles, or an orderly sale or wind-down. Mediation can work well when both owners want to preserve value, and an independent valuation can narrow arguments about price. Where the documents include a buy-sell mechanism, using it may be faster than any lawsuit. Litigation remains available when one side is acting in bad faith or assets are at risk, and some situations call for quick court relief. When we first sit down, we go through the documents, the finances, and your goals, and we discuss which direction fits: staying in, getting out, or holding your position while the facts become clearer.
