Buy-Sell Agreements for Multi-Owner Businesses

Buy-Sell Agreements for Multi-Owner Businesses

A buy-sell agreement is a legally binding contract that controls what happens to an owner's share of a business when a triggering event occurs, such as death, disability, divorce, or a voluntary exit. Without one, your co-owner's spouse, estate, or a stranger could end up as your new business partner. Every multi-owner business in Florida should have one in place before a problem forces the issue.

What is a buy-sell agreement and why does it matter?

Think of a buy-sell agreement as a prenuptial agreement for your business. It answers the hard questions in advance, while everyone is still on good terms and thinking clearly. Who gets to buy a departing owner's interest? At what price? On what payment terms? What events trigger the buyout in the first place?

Without this document, Florida's default rules under the Florida Revised Limited Liability Company Act or the Florida Business Corporation Act fill in the gaps. Those defaults rarely match what the owners actually want, and sorting it out in court is expensive and slow. A well-drafted buy-sell agreement keeps a business dispute from turning into full-blown business litigation.

What events should a buy-sell agreement cover?

A solid agreement addresses at least six scenarios:

Death. When an owner dies, their interest passes to their estate or heirs under Florida probate law. Those heirs may have no interest in running the business and every interest in cashing out at the highest possible price. A buy-sell agreement can require the surviving owners to purchase the deceased owner's interest at a predetermined price or formula.

Disability. A long-term disability that prevents an owner from contributing to the business is often more disruptive than death. The agreement should define what counts as a disability (typically inability to perform duties for 90 or 180 consecutive days) and set the buyout mechanism.

Voluntary departure. If an owner wants to leave, the remaining owners should have the first right to purchase the interest before it can be sold to an outsider. This is called a right of first refusal.

Involuntary transfer. Divorce, bankruptcy, and creditor judgments can all threaten to transfer an ownership interest to someone the other owners never agreed to work with. A well-drafted agreement restricts those transfers.

Deadlock. When two equal owners simply cannot agree on the direction of the business, the agreement can include a buyout mechanism, sometimes called a shotgun or Texas shoot-out clause, that forces a resolution without litigation.

Retirement. If an owner wants to phase out over time, the agreement can set a timeline and payment structure that works for everyone.

How is the buyout price determined?

This is where most buy-sell agreements get it wrong. Owners agree to use a fixed dollar figure, update it once, and then forget it for a decade. By the time a triggering event actually occurs, the number is completely disconnected from reality.

There are three common approaches:

1. Fixed price, which must be reviewed and updated annually to stay meaningful.
2. Formula-based valuation, such as a multiple of EBITDA or annual revenue. As of 2026, a common starting point for small service businesses is three to five times adjusted EBITDA, though the right multiple depends heavily on the industry.
3. Third-party appraisal, which is the most accurate but also the most expensive and time-consuming at the moment you need certainty the most.

Many well-structured agreements use a formula as the default and require a third-party appraisal if either party disputes the result within a set window, often 30 days.

What type of buy-sell agreement structure should you use?

There are two main structures:

Cross-purchase agreement. Each owner agrees to buy the others' interests directly. This works well in smaller two-owner businesses, especially when paired with life insurance policies that owners take out on each other to fund the death buyout.

Entity-purchase (redemption) agreement. The business itself buys back the departing owner's interest. This simplifies administration when there are three or more owners, but it has different tax consequences that your accountant and attorney need to coordinate on.

Some businesses use a hybrid approach. The tax treatment for each structure is meaningfully different, so getting this right from the start matters. This is not a document to download from a website.

How does life insurance connect to this?

Life insurance is the most common funding mechanism for death buyouts. Each owner is insured for an amount approximating their buyout value, and the proceeds fund the purchase when the time comes. This only works if the insurance coverage is reviewed alongside the valuation formula. If your business has grown significantly and the policies haven't kept pace, the surviving owners may face a shortfall exactly when they can least afford one.

For disability buyouts, disability buyout insurance exists and is worth exploring, though it tends to be more expensive and has stricter underwriting.

Does a buy-sell agreement affect estate planning?

Yes, significantly. If an owner dies and the buy-sell agreement controls the value of the business interest for estate purposes, that price may also set the taxable value of the estate. The IRS has rules under 26 U.S.C. 2703 about when a buy-sell price will or won't be respected for estate tax purposes. A buy-sell agreement that was designed without an eye toward estate planning can create an unexpected tax problem for the owner's family.

If you're working through your own estate planning, your business interests need to be part of that conversation, not treated as a separate topic. The two documents need to coordinate, especially when a trust is involved. You can review how trusts interact with other planning tools in our trust vs will guide.

What does a buy-sell agreement cost in Florida?

A properly drafted buy-sell agreement for a small Florida business typically runs between $1,500 and $5,000 in legal fees depending on complexity, the number of owners, and whether it needs to coordinate with existing operating agreements, shareholder agreements, or estate plans. That number goes up if the business has unusual ownership structures or multiple classes of membership interests.

Compare that to the cost of business disputes when there is no agreement: litigation over a forced buyout or a disputed valuation can easily reach five or six figures before it resolves, and that assumes it resolves at all.

When is the right time to put one in place?

The right time is when the business is formed. The second-best time is right now. Buy-sell agreements get harder to negotiate as the business grows because the stakes are higher, relationships may be more strained, and owners have stronger opinions about valuation. If you already have an agreement but haven't reviewed it in more than two years, treat this as a prompt to pull it out and check the numbers.

Frequently asked questions

Can an operating agreement substitute for a buy-sell agreement?

An operating agreement can include buy-sell provisions, and many do. But a standalone buy-sell agreement is often more detailed, easier to update without amending the full operating agreement, and easier to coordinate with life insurance policies. If your operating agreement has basic transfer restrictions but no valuation formula or funding mechanism, it is not doing the job of a true buy-sell agreement.

What happens if a co-owner dies and there is no buy-sell agreement?

The deceased owner's interest passes to their estate and eventually to their heirs under Florida probate law. Those heirs become your new co-owners unless the operating agreement restricts the transfer. Even if the transfer is restricted, you may face a legal fight over the value of the interest and the terms of any buyout. That process can take months and cost far more than the agreement would have.

Does a buy-sell agreement need to be notarized in Florida?

Notarization is not required for a buy-sell agreement to be enforceable in Florida, but it is common practice and can help with authentication if the agreement is ever challenged in court. More important than notarization is making sure the agreement is actually signed by all parties and stored somewhere accessible, not just in one owner's email inbox.

How often should a buy-sell agreement be reviewed?

At minimum, every two to three years, or whenever a significant event occurs: a new owner joins, an owner leaves, the business takes on significant debt, revenue doubles, or any owner's personal situation changes materially. If you funded the buyout with life insurance, review the policy coverage at the same time. A stale agreement with outdated numbers can cause as many problems as no agreement at all.

Can a buy-sell agreement restrict a divorce transfer in Florida?

Yes, with careful drafting. A buy-sell agreement can require that any transfer of a business interest resulting from a divorce decree triggers a right of first refusal or an automatic buyout. However, Florida divorce courts have discretion over marital asset division, and an agreement that is not structured properly may not be enforceable against a non-owner spouse. This is an area where the agreement language matters a great deal.
