What You Need to Know About Partnership Agreements

By Michael D. Rubin, CEO & Founder · Updated September 2026 · 728 words

The most important thing to know about a partnership agreement is that its value shows at the end, not the beginning: it decides what happens when a partner wants out, when one dies or divorces, and when a buyer offers to purchase the whole company. Most co-owners write the start-up sections carefully and treat the exit sections as boilerplate. The exit sections are the ones that end up in dispute.

If you are buying a business with a partner, or already own one together, these are the points to get right.

Put it in writing, whatever the relationship

Friends and relatives are the partners most likely to skip a written agreement and the ones with the most to lose when a disagreement turns personal. Every co-owned business needs one, whether it is called a partnership agreement, an LLC company agreement or a shareholders' agreement. The sections on ownership, pay and daily decisions matter. The exit sections matter more, because they are written for the day the partners no longer agree. A short agreement signed on the first day is worth more than a thorough one that never gets finished.

How one partner leaves

Owners leave for predictable reasons: retirement, burnout, a new opportunity, illness, death, divorce or a falling-out. For each, the agreement should say whether the remaining owners have the right or the obligation to buy the departing owner's share, how the price is set and how it is paid. Paying a departing partner in full at once can drain a company; installments over a set period, or insurance for death and disability, are common answers.

The price method is where most agreements are weakest. A fixed figure written in years ago will be wrong. A formula, an annually agreed value or an independent appraisal at the time of exit is better. A formal business valuation is the usual way to settle it fairly, and our guide to what a business is worth explains the methods buyers use.

How the whole company gets sold

Sooner or later, a buyer may offer to purchase the entire business. The agreement should say who can accept. Three provisions do most of the work, and a right of first refusal, which lets the existing owners match any outside offer for one partner's share, covers most of what remains:

• Approval threshold. Whether a sale of the company needs a simple majority, a larger majority or every owner.
• Drag-along rights. If the required majority approves a sale, the minority must sell on the same terms, so one holdout cannot block a deal the others want.
• Tag-along rights. If a majority owner sells, the minority can join on the same terms instead of being left with a partner they did not choose.

Alternatives to a full sale

Not every exit means selling everything. When one partner wants to cash out and another wants to keep going, a recapitalization, in which an investor buys part of the company and the continuing owner keeps a stake, can pay out the departing partner without a sale to a single buyer. Our article on recapitalization versus a complete sale explains when that fits. Make sure your agreement does not rule such a transaction out by requiring terms no investor would accept.

Why buyers and lenders will read your agreement

When the day comes to sell the company, the buyer's attorney will ask for the governing agreement early in due diligence. They want to know that the people signing can bind the company, that no former partner has a claim, and that every owner's share is properly documented. Missing signatures, informal promises of equity to a key employee, or a partner who left without a documented buyout can delay a closing or reduce the price. A lender to a buying group reads the same document to see who controls the borrower.

How MDR & Associates sees it from the deal table

MDR & Associates represents owners selling established Texas companies with $3 million to $100 million in annual revenue, and many of those companies have more than one owner. A clear agreement lets co-owners give one answer to a buyer's offer and one set of instructions to their advisor. Your attorney drafts the agreement; we can help partners understand what their company might be worth and what a sale would involve. To start that conversation confidentially, contact the firm.

Questions owners ask next

What if my partner and I disagree about selling the company?

Look at the agreement first. It may set the approval threshold, give one side drag-along rights or provide a buyout mechanism. If it is silent, the options are negotiation, mediation or one partner buying the other out, and each is easier with a professional view of what the company is worth.

Should a partner buyout be paid all at once?

Rarely. A lump sum can strain the company's cash, so agreements often allow installments over a set period, sometimes with interest and security for the departing owner. Life and disability insurance can fund buyouts triggered by death or disability. Your attorney and CPA can set terms the business can afford.
