Buy-Sell Agreements for LLCs: How to Protect Your Business and Its Members

Your LLC operating agreement probably doesn't cover what happens when a member dies or wants out. Most operating agreements include a few paragraphs about transferring membership interests, but they rarely address the hard questions: Who buys the departing member's share? How much do they pay? Where does the money come from?

That's where a buy-sell agreement comes in. It's a legally binding contract between LLC members that spells out exactly what happens to ownership interests when a triggering event occurs—death, disability, retirement, divorce, or a member simply wanting to leave.

Without one, you're leaving your business and your members exposed to disputes, forced sales, and unwanted new partners.

Why LLCs Need a Separate Buy-Sell Agreement

Most LLC operating agreements include basic transfer restrictions. They might say that a member can't sell their interest to an outsider without the consent of the other members. That's a start, but it's nowhere near enough.

Here's what operating agreements typically don't address:

• Funding. Even if the operating agreement says the remaining members can buy out a departing member, it doesn't say where the money comes from. And that's the whole problem.
• Valuation methodology. "Fair market value" sounds reasonable until two parties disagree on what that means. A buy-sell agreement locks in a specific valuation method so there's no room for argument.
• Timeline and payment terms. When does the buyout happen? Is it a lump sum or installment payments? Over how many years? At what interest rate?
• Specific triggering events. Death is obvious. But what about disability? Divorce? Bankruptcy? A member who just stops showing up?

A buy-sell agreement fills every one of these gaps. Think of it as the financial and operational companion to your operating agreement—the document that makes your ownership structure actually work under pressure.

Buy-Sell Agreement vs. Operating Agreement

These two documents serve different purposes, but they need to work together. Here's how they compare:

You need both. The operating agreement runs your LLC. The buy-sell agreement protects it when membership changes. Make sure they don't contradict each other—your attorney should draft or review them together.

How Buy-Sell Agreements Work in an LLC

The mechanics of an LLC buy-sell agreement depend on how your LLC is structured and managed.

Member-Managed LLCs

In a member-managed LLC, all members participate in running the business. The buy-sell agreement typically gives remaining members the right (or obligation) to purchase a departing member's interest directly. Every member is both an owner and an operator, so the agreement needs to address both the financial and operational transition.

Manager-Managed LLCs

In a manager-managed LLC, one or more designated managers run the business while other members are passive investors. The buy-sell agreement needs to account for the different roles—losing a managing member has different implications than losing a passive investor. The agreement might include different terms or triggers depending on the member's role.

Membership Interest Transfer Mechanics

When a triggering event occurs, the buy-sell agreement sets the process in motion:

1. The triggering event is identified and verified (death certificate, disability determination, written notice of withdrawal, etc.).
2. The valuation process begins, following the method specified in the agreement.
3. The buying party (remaining members or the LLC itself) is obligated to purchase at the determined price.
4. Payment is made according to the terms—lump sum from insurance proceeds, installments, or a combination.
5. The membership interest is transferred, and the operating agreement is updated to reflect new ownership percentages.

The key point: none of this works if the agreement doesn't exist, or if it exists but isn't funded. The agreement creates the obligation. Insurance creates the ability to fulfill it.

Types of LLC Buy-Sell Agreements

There are two primary structures for LLC buy-sell agreements. Which one works best depends on the number of members, tax considerations, and how you want to handle the mechanics.

Cross-Purchase Agreement

Each member buys coverage on the other members. When a member dies or triggers a buyout, the remaining members use the insurance proceeds to purchase that member's interest directly from them (or their estate).

Entity-Purchase (Redemption) Agreement

The LLC itself buys coverage on each member. When a triggering event occurs, the LLC buys back the departing member's interest. The remaining members' ownership percentages increase proportionally.

Triggering Events for LLCs

A thorough LLC buy-sell agreement addresses every realistic scenario that could cause a membership change. Here are the events your agreement should cover:

• Death. The most obvious trigger. The agreement specifies whether the deceased member's interest is purchased by remaining members, the LLC, or both—and ensures the estate receives fair compensation.
• Disability. Define what qualifies as disability (typically the inability to perform duties for a specified period, such as 6 or 12 months). Include how disability is determined and who makes that call.
• Retirement. If members have different retirement timelines, the agreement should address how and when a retiring member can exit and at what price.
• Voluntary withdrawal. A member decides they want out. The agreement should specify notice requirements, a cooling-off period, and the buyout terms—which may differ from a death or disability buyout.
• Involuntary removal. Sometimes a member needs to be removed for cause—breach of fiduciary duty, criminal conduct, or failure to meet obligations. The agreement should define what constitutes cause and the process for removal.
• Divorce. This one is critical for LLCs. If a member's spouse receives a portion of their membership interest in a divorce settlement, the remaining members could end up with an unwanted business partner. The agreement should require the divorcing member to buy back any interest awarded to a spouse, or trigger a buyout by the LLC.
• Bankruptcy. If a member files for personal bankruptcy, their membership interest could become an asset of the bankruptcy estate. The agreement should include provisions to prevent a bankruptcy trustee from becoming a member.

Funding Your LLC Buy-Sell Agreement

A buy-sell agreement without funding is just a piece of paper. It creates the obligation to buy, but it doesn't create the ability to pay. And that's the part most LLCs get wrong.

Here's the math. Say your LLC is worth $2 million and has two equal members. If one member dies, the surviving member is obligated to buy the deceased member's 50% interest—that's $1 million. Where does that money come from?

• Cash reserves? Most LLCs don't have $1 million sitting in the bank.
• A business loan? Good luck getting one when you just lost a key member and your revenue is about to take a hit.
• Installment payments? The estate may not want to wait 5–10 years to be paid out, especially if they need the money to support the deceased member's family.

Insurance solves this problem. Each member (or the LLC) carries coverage on the other members equal to their buyout obligation. When a member dies, the coverage pays out immediately—providing the exact cash needed to complete the buyout without draining the business or taking on debt.

The cost of funding is remarkably low relative to the protection it provides. For two healthy members in their 40s, $1 million in term coverage for each might cost $100–$300 per month total—a fraction of what either member generates in revenue.

Valuation Methods for LLC Interests

The valuation method in your buy-sell agreement determines the price paid for a departing member's interest. Get this wrong, and you'll either overpay (hurting the business) or underpay (inviting a lawsuit from the departing member or their estate).

Fixed Price

Members agree on a specific dollar value for the business and update it annually. Simple and predictable, but only works if you actually update it. We've seen agreements with fixed valuations that haven't been revised in 10 years—during which the business tripled in value.

Formula-Based

The agreement specifies a formula (e.g., 4x annual net income, or 1.5x revenue) to calculate value at the time of the triggering event. No need for annual updates, but the formula needs to reflect how businesses in your industry are actually valued.

Independent Appraisal

A qualified business appraiser determines fair market value at the time of the event. Most accurate, but also the most expensive and time-consuming. Can delay the buyout process by weeks or months.

Hybrid Approach

Use a fixed price or formula as the default, with either party having the right to request a formal appraisal if they disagree. This balances efficiency with fairness and is the approach we recommend for most LLCs.

Special Considerations for Multi-Member LLCs

When your LLC has three or more members, the buy-sell mechanics get more complex.

Cross-Purchase Complexity

With a cross-purchase agreement, each member needs coverage on every other member. For a 2-member LLC, that's 2 coverages. For 3 members, it's 6. For 4 members, it's 12. For 5 members, it's 20. The administrative burden grows fast, and the total cost increases with every additional member.

Unequal Ownership Stakes

When members own different percentages, the buyout obligations are different for each member. A member with a 10% stake has a much smaller buyout obligation than a member with a 50% stake. Cross-purchase agreements need to account for this asymmetry.

Entity-Purchase Simplicity

For LLCs with 4 or more members, entity-purchase agreements are often the better choice. The LLC carries one coverage per member, making administration straightforward. When a buyout occurs, the LLC handles the entire transaction and remaining ownership percentages adjust automatically.

Adding New Members

Your buy-sell agreement should include provisions for adding new members—requiring them to sign onto the agreement as a condition of joining the LLC. Otherwise, you'll have some members bound by the agreement and others who aren't, which defeats the entire purpose.

Common LLC Buy-Sell Mistakes

We see these errors repeatedly, and every one of them can be avoided with proper planning:

Relying on the Operating Agreement Alone

The operating agreement was never designed to handle the financial mechanics of an ownership transition. It sets the rules for running the business, not for funding a buyout. Treating it as a substitute for a buy-sell agreement is like treating a job description as an employment contract.

Not Funding the Agreement

This is the single most common and most dangerous mistake. An unfunded agreement creates a legal obligation with no financial backing. When a triggering event occurs, the remaining members scramble for cash they don't have, and the departing member (or their estate) is left waiting for money that may never come.

Ignoring Divorce as a Triggering Event

In many states, membership interests in an LLC are considered marital property. If your buy-sell agreement doesn't address divorce, a member's ex-spouse could end up with a claim to part of the business. This is one of the most overlooked provisions, and one of the most consequential.

Failing to Update When Membership Changes

When a new member joins or an existing member leaves, the buy-sell agreement needs to be updated. Ownership percentages change, coverage amounts need adjustment, and the new member needs to be a party to the agreement. Failing to update creates gaps that can render the entire agreement unenforceable.

Choosing the Wrong Valuation Method

A fixed-price valuation that never gets updated. A formula that doesn't reflect how your industry actually values businesses. An appraisal requirement that slows the buyout by months. The valuation method needs to be realistic, current, and appropriate for your specific business.

Setting Up a Buy-Sell Agreement for Your LLC

The process is more straightforward than most LLC members expect. From initial conversation to a fully funded, executed agreement, you're looking at roughly 30 days.

Week 1: Assessment

We review your LLC structure, operating agreement, number of members, ownership percentages, and overall business valuation. We identify which triggering events matter most for your situation and discuss cross-purchase vs. entity-purchase structures.

Week 2: Design and Drafting

Based on the assessment, we work with your attorney to draft the buy-sell agreement. Simultaneously, we determine the coverage amounts needed for each member and begin the approval process.

Weeks 3–4: Approval and Execution

Members complete their health questionnaires and any required exams. Coverage is approved and bound. The buy-sell agreement is executed by all members. Your LLC is now protected.

Once the agreement is in place, we schedule annual reviews to ensure valuations stay current, coverage amounts remain adequate, and any membership changes are reflected in the agreement.

Protect Your LLC Before You Need To

Every LLC with two or more members needs a funded buy-sell agreement. Not eventually. Not when you get around to it. Now. The triggering events this agreement protects against—death, disability, divorce—don't send advance notice. When they happen, your members either have a clear, funded plan in place, or they're left scrambling.
