The Buy-Sell Agreement Every Business With Partners Should Have

By MercConsulting · Published 2026-08-21 · Updated 2026-09-07

A buy-sell agreement decides what happens to a partner's interest on death, disability, divorce, departure or deadlock, at what price and with what money. What it must cover and why it has to exist before a dispute.

A buy-sell agreement is a contract among the owners of a business, and often the business itself, that decides in advance what happens to an owner's interest when a trigger event occurs: death, disability, divorce, departure, bankruptcy or deadlock. It fixes who can buy, who must sell, how the price is set and where the money comes from. Without one, an owner's share passes to whoever inherits it or wins it in court, and the remaining partners find themselves in business with someone they never chose, at a price nobody agreed.

This article explains what happens by default when there is no agreement, the trigger events a good one covers, the ways the price can be set, the cross-purchase and redemption structures and how each is funded, how the agreement fits the operating agreement and your estate plan, and how to get one done. The short answer is not the whole answer because most operating agreements contain a paragraph on transfers that owners mistake for a buy-sell, and because an agreement with no funding behind it is a promise nobody can keep.

"We were three equal partners with a handshake. When one of us went through a divorce, we spent a year and a lot of legal fees finding out what the handshake meant. The agreement we have now took a month to write."

What Happens to a Partner's Share Without a Buy-Sell Agreement

Texas law fills the gap with default rules that satisfy nobody. When a member of an LLC dies, the membership interest passes through the estate to the heirs as assignees. An assignee is entitled to the economic rights, meaning the distributions that interest would receive, but is not a member and has no vote or management rights unless the company agreement or the remaining members admit them. The surviving partners now run a company whose profits partly flow to someone who does not work there and cannot be forced to sell; the heirs own something they cannot manage or easily sell.

Divorce works the same way in a community property state: a spouse awarded part of an interest becomes an assignee with a claim on distributions. A disabled partner keeps drawing while contributing nothing, with no mechanism to buy them out. A partner's personal creditor obtains a charging order against distributions. Two equal partners who cannot agree simply stop, with no exit for either. Each of these has a clean solution in an agreement drafted in advance and none afterward, which is why it ranks among the LLC formation mistakes we see most and belongs on the checklist of what to do after forming an LLC.

The Trigger Events to Cover

• Death. The estate must sell and the company or the surviving owners must buy, at a price and on terms fixed in the agreement.
• Disability. Defined by duration, usually matching the definition in the disability buyout policy so the trigger and the funding line up.
• Divorce. A spouse awarded any part of an interest must offer it back at the agreement price; spouses sign an acknowledgment when the agreement is executed.
• Voluntary departure or retirement. Notice periods, a non-compete, and often a lower price for a partner who leaves early or badly than for one who retires on schedule.
• Termination for cause. What counts as cause, and a price that reflects it.
• Bankruptcy or creditor attachment. An option for the others to buy before a creditor becomes a permanent assignee.
• Loss of a professional license, for firms where ownership requires one.
• Deadlock. A mediation step, then a buyout mechanism such as a shotgun clause, where one partner names a price and the other chooses whether to buy or sell at it.
• Attempted transfer to an outsider. A right of first refusal or first offer for the company and the other owners.

A trigger that is not listed is a trigger the agreement does not handle, so the list should be long and the definitions precise.

How the Price Gets Set

The price can differ by trigger. Death and retirement typically pay full value; a partner who leaves early or is terminated for cause may receive a discount, which discourages abrupt exits. Whether minority and marketability discounts apply should be stated, not left to argument. For family-owned businesses the tax rules add conditions before a buy-sell price will be respected for estate tax purposes, which your attorney and CPA must address. The mechanics of valuing a small company are covered in our article on small business valuation.

Where the Money Comes From: Cross-Purchase, Redemption and Funding

Two structures dominate. In a cross-purchase agreement, the remaining owners personally buy the departing owner's interest, and each owner holds life and disability policies on the others. In an entity redemption, the company buys the interest back and owns the policies. A hybrid lets the parties choose at the time of the trigger. The choice affects how many policies are needed, who pays the premiums, and the tax basis the survivors receive in the purchased interest, which is why it is a CPA question as much as a legal one.

Funding is the difference between an agreement and a wish. Life insurance handles death cleanly if the coverage matches the price. Disability buyout insurance handles disability. Everything else, from retirement to deadlock, is usually paid with a down payment and an installment note over several years, secured by the interest being sold, with interest, a term and a personal guarantee from the buyer. A sinking fund inside the company can supplement it. Without a funding plan, the survivors face a choice between a purchase they cannot afford and a partner they never chose.

If your partners agree that this matters and nobody has started, the free 30-minute discovery call is a sensible first step; we help partners settle the business terms before the lawyer's clock starts.

How the Buy-Sell Fits the Operating Agreement and Your Estate Plan

The buy-sell can live inside the company agreement or stand alone, but the two must not contradict each other. Transfer restrictions, permitted transfers to trusts for estate planning, drag-along and tag-along rights, and confidentiality and non-compete terms on exit all need to point the same direction. Wills and trusts should reference the agreement, beneficiary designations on the funding policies should match the structure, and spouses should sign acknowledgments so the divorce trigger is enforceable. Because the agreement sets what your family receives for your interest, it is a core piece of estate planning for business owners and of any succession plan.

Why It Must Be Drafted Before a Dispute, and How to Get It Done

While every partner is healthy, married and equally committed, nobody knows which side of a trigger they will land on, so the terms come out fair. After a diagnosis, a separation or a falling-out, each partner knows exactly which terms favor them, and agreement becomes expensive or impossible. The process is short when it starts early.

1. Inventory the owners, their spouses and the triggers that matter for your business.
2. Agree the structure: cross-purchase, redemption or hybrid.
3. Choose the valuation method and whether the price differs by trigger.
4. Fund it: insurance quotes for death and disability, note terms for everything else.
5. Have the attorney draft, the CPA review the tax effects, and everyone sign, spouses included.
6. Calendar a review every two or three years, and whenever value changes materially or an owner joins or leaves.

Where MercConsulting Fits

MercConsulting is a boutique business consulting firm in Houston, Texas, organized around five outcomes, and the buy-sell sits under Protect Assets: it protects your family's share of the value and protects the company from an unplanned partner. We are not a law firm and we do not draft the agreement. What we do is help partners reach agreement on the business terms, the triggers, the valuation approach and the funding, prepare the financial picture the valuation relies on, and coordinate the attorney, CPA and insurance adviser who draft, model and fund it. Most of what we recommend we can also build, including the record-keeping that makes the annual price update actually happen.

We are not a CPA firm, insurance agency or investment adviser either. The legal drafting, the tax analysis and the policies come from licensed professionals; our role is to make sure the business terms are settled and the process finishes.

Frequently Asked Questions

What happens if my business partner dies and we have no buy-sell agreement?

The partner's interest passes through the estate to the heirs, who under Texas default rules become assignees with a right to distributions but no vote or management role unless admitted as members. You cannot force them to sell and they cannot force you to buy, so you may be running a company that pays profits to people who do not work there. A buy-sell agreement replaces that with a fixed price, a funded purchase and a clean exit.

Should the buy-sell agreement be part of the operating agreement or a separate document?

Either works, provided the two never contradict each other. Many small companies put the buy-sell provisions inside the company agreement so there is one document to maintain; others use a standalone agreement, especially when the company and insurance policies are parties. What matters is that transfer restrictions, triggers, price and funding are all addressed, that spouses sign, and that both documents are reviewed together whenever one changes.

How is the price determined in a buy-sell agreement?

By whichever method the owners chose in advance: a fixed price updated each year with a fallback, a formula such as a multiple of earnings, an independent appraisal, or a combination in a stated sequence. The price can differ by trigger, with full value on death or retirement and a discount for an early or for-cause departure. State whether minority discounts apply, and have your CPA and attorney address the estate-tax conditions for family-owned companies.

What is the difference between a cross-purchase and an entity redemption agreement?

In a cross-purchase, the remaining owners personally buy the departing owner's interest and hold the insurance policies on each other. In an entity redemption, the company buys the interest and owns the policies. Cross-purchase generally gives the buyers a higher tax basis in what they acquire but needs more policies as the owner count grows; redemption is simpler to administer but raises valuation and tax questions your CPA should model.

Does a buy-sell agreement protect the business if a partner gets divorced?

It can, if divorce is a listed trigger and the spouses signed acknowledgments when the agreement was executed. A typical provision requires any interest awarded to a former spouse to be offered back to the partner or the company at the agreement price, so the former spouse becomes a paid seller rather than a permanent assignee. Family law and the agreement interact, so have a Texas attorney draft the provision.
