Buy-Sell Agreements: What Happens to a Colorado Business When an Owner Leaves, Dies, Becomes Disabled, or Divorces?

When you build a company with someone, you are also trusting each other with employees’ livelihoods, family wealth, customer relationships, and years of work. A buy-sell agreement turns that trust into a practical plan so no one has to invent the rules during a departure, disability, divorce, or loss.

In general terms, a buy-sell agreement restricts how owners may transfer their interests and gives the business, the other owners, or both a right—and sometimes an obligation—to purchase an owner’s interest after a specified event. It may appear in an LLC operating agreement, shareholder agreement, partnership agreement, or separate contract, as explained in this overview of buy-sell agreements and insurance funding.

For a Colorado business, the goal is not merely to have a document labeled “Buy-Sell Agreement.” The goal is to create coordinated instructions answering four questions:

What event activates the agreement?
Who may or must purchase the affected ownership interest?
How will the purchase price be determined?
Where will the buyer obtain the money?

If any answer is missing, the owners may still face an expensive negotiation at exactly the moment when time, cash, and emotional capacity are limited.

What does a buy-sell agreement actually do?

Think of the agreement as an ownership-transition map. It can address voluntary events, such as retirement or a planned sale, and unexpected events, such as death, permanent disability, bankruptcy, or a transfer risk connected to divorce. These are commonly called triggering events; possible triggers extend beyond death to include permanent disability, termination of employment, and potential involuntary transfers arising from divorce or bankruptcy, according to this detailed discussion of buy-sell provisions.

For every trigger, the agreement should identify whether a purchase is:

Mandatory: The seller must sell and the designated buyer must buy.
Optional: The business or remaining owners may choose whether to buy.
Sequential: One buyer receives the first opportunity, followed by another if the first declines.
Subject to a right of first refusal: The owner may seek an outside buyer, but the existing owners or company receive the first chance to match the proposed terms.

Those choices matter. A right to buy is not the same as a duty to buy, and a restriction on transferring management or voting rights is not necessarily the same as a requirement to purchase the economic interest.

When an owner wants to leave or retire

A planned exit can still become disruptive if the documents do not establish timing, notice, price, and payment terms.

Owners should decide in advance:

How much written notice a departing owner must provide.
Whether the company, the remaining owners, or both may purchase the interest.
Whether an outside sale is allowed.
Whether the other owners have a right of first refusal.
Whether the purchase price is paid at closing or over time.
What security, interest, or default protections apply if the seller accepts installment payments.
Whether employment termination triggers a buyout even when the person remains an owner.
Whether different rules apply to retirement, resignation, or termination for cause.

The agreement should also separate ownership value from amounts the business may separately owe the departing owner, such as compensation, reimbursable expenses, or documented loans. Combining everything into one undefined “buyout” number invites disagreement.

When an owner dies

After an owner’s death, the family may need liquidity while the remaining owners need continuity. A buy-sell agreement can create an orderly exchange: the estate or successor transfers the ownership interest, and the identified buyer pays the price established under the agreement.

The drafting questions include:

Does the surviving owner have the first option to buy?
Must the company redeem the interest if the surviving owner declines?
Who receives payment—the estate, a trust, or another successor?
When must the transfer close?
How is the value measured as of the owner’s death?
Does the agreement’s valuation process coordinate with the company’s life-insurance coverage?
What happens if the insurance proceeds are less than the purchase price?

Life insurance can supply cash at death, but it does not repair unclear purchase terms. The agreement and policy records should agree on who owns each policy, who pays the premiums, who receives the proceeds, and how those proceeds are intended to be used.

When an owner becomes disabled

“Disability” should not be left as an everyday-language concept. The agreement needs an administrable standard.

Questions to resolve include:

Is the trigger based on inability to perform the owner’s usual duties or any duties?
How long must the condition continue before a buyout begins?
Who determines disability—a treating physician, an independent physician, an insurer, or another process?
Can the owner return during a waiting period?
Is the buyout mandatory or optional?
How will the purchase be funded if no death benefit is payable?
How do salary, benefits, voting rights, and management authority operate before closing?

A disability provision should also coordinate with employment agreements and insurance policies. Otherwise, one document may say that an owner’s employment has ended while another leaves that person’s management or voting authority unresolved.

When an owner divorces

Divorce planning should be handled carefully and without assuming that a business contract alone decides every family-law issue. A buy-sell provision can address the risk of an involuntary transfer by establishing purchase rights, transfer restrictions, or procedures that activate when an ownership interest becomes involved in a divorce proceeding. Buy-sell triggers may include a potential involuntary transfer arising from divorce, as this business-succession analysis explains.

The agreement should clearly address questions such as:

What precise event triggers the provision: filing, entry of an order, an attempted transfer, or an actual transfer?
Does the company or another owner receive an option or a mandatory purchase right?
Is the affected owner required to notify the company?
How is the interest valued, and on what date?
Must owners obtain spousal acknowledgments or consents?
How will the business protect confidential financial and operational information while complying with lawful disclosure obligations?

These provisions should be reviewed with Colorado business, family-law, and tax considerations in mind. They should also coordinate with any prenuptial or postnuptial agreement. The documents may serve different purposes, and one should not silently contradict another.

Who buys: the company or the other owners?

Two common structures are an entity purchase, often called a redemption, and a cross-purchase.

Entity purchase or redemption

The company buys the departing or deceased owner’s interest. When insurance is used for a death buyout, the company may own the policies, pay the premiums, receive the proceeds, and use the cash for the redemption.

This may be administratively straightforward, but the tax and valuation consequences need careful review—especially after the U.S. Supreme Court’s 2024 decision in Connelly v. United States.

Cross-purchase

The remaining owners purchase the affected owner’s interest. In an insurance-funded arrangement, the owners may own policies on one another and use the proceeds to complete the purchase.

Cross-purchase planning can become cumbersome as the number of owners grows because multiple policies may be needed. It can also raise questions involving premium allocation, policy ownership, insurability, and what happens when an owner joins or leaves.

Hybrid or sequential structure

Some agreements give the remaining owners the first opportunity to buy and then require or permit the company to redeem the interest if they decline. That flexibility can be useful, but the agreement must clearly state the order, deadlines, allocation among buyers, and funding mechanics.

No structure is automatically best for every Colorado company. Entity type, ownership percentages, tax classification, number and ages of owners, insurability, cash flow, and estate plans can all affect the decision.

How should the business be valued?

A buyout promise without a workable valuation method is incomplete. The parties may agree on the trigger and buyer yet still end up disputing the price.

Common approaches include:

1. Fixed agreed value

The owners sign a certificate or schedule stating the company’s current value. This can be simple, but only if they update it regularly. A value set years ago may no longer reflect new contracts, debt, real estate, intellectual property, equipment, or changes in profitability.

2. Formula value

The agreement uses a defined formula tied to specified financial information. A formula must identify the data source, measurement period, treatment of owner compensation, debt, cash, insurance proceeds, unusual income or expenses, and any applicable discounts or adjustments.

3. Independent appraisal

A qualified appraiser values the interest when the trigger occurs. The agreement should say who selects the appraiser, what standard and valuation date apply, who pays the cost, and how disagreements are resolved.

4. Multiple-appraiser process

Each side may select an appraiser, with a third appraiser used if the first two results differ beyond an agreed range. Although this can provide a dispute mechanism, it can also add time and expense.

Buy-sell agreements commonly use either an appraisal at the relevant time or a valuation formula; when a formula is used, it is especially important to review it periodically to confirm that it still produces an appropriate value, according to this analysis of valuation provisions.

Whatever method the owners choose, the agreement should distinguish between the value of the entire company and the value of the particular ownership interest being purchased. It should also state whether life-insurance proceeds are included in the valuation and ensure that the contractual method is actually followed.

Funding: a purchase obligation needs a realistic source of money

A buy-sell agreement can be legally operative without a dedicated funding mechanism, but funding is what makes the planned purchase financially manageable. Life insurance is commonly used for death-triggered obligations because it can provide liquidity when an owner dies; the proceeds may cover all or only part of the required purchase, as described in this insurance-funded buy-sell guide.

Possible funding sources include:

Company cash reserves.
Personal funds of the remaining owners.
Life-insurance proceeds.
Available disability-related coverage structured for the plan.
Bank financing.
An installment note issued to the departing owner or estate.
A combination of these sources.

The agreement should anticipate a shortfall. If the purchase price is $2 million but only $1.2 million is available, does the balance become a promissory note? Over what period? At what interest rate? Is the obligation secured? Can the business prepay? What happens after a payment default?

Insurance coverage also needs periodic attention. A policy purchased when the company was worth $1 million may not adequately support a buyout after years of growth. Conversely, policy ownership and beneficiary designations should not be changed casually because they are part of the agreement’s larger legal and tax structure.

The Connelly decision: company-owned life insurance can affect estate-tax value

The Supreme Court decided Connelly v. United States on June 6, 2024. Two brothers owned a corporation with an agreement giving the surviving brother the option to purchase the deceased brother’s shares; if he declined, the corporation was required to redeem them. The corporation held $3.5 million of life insurance on each brother.

After Michael Connelly died, the surviving brother declined to purchase the shares, and the corporation redeemed them. The estate argued that the corporation’s obligation to redeem the shares offset the insurance proceeds when valuing the company for federal estate-tax purposes.

The Supreme Court rejected that position. Its holding was precise: “A corporation’s contractual obligation to redeem shares is not necessarily a liability that reduces a corporation’s value for purposes of the federal estate tax.” The unanimous Court, in Connelly v. United States, 602 U.S. 257 (2024), explained that a redemption at fair market value “has no effect on any shareholder’s economic interest.” See the Court’s opinion, syllabus, and holding in Connelly.

That does not mean life insurance is inherently a poor funding tool, nor does it mean every entity-owned policy produces the same result. It means an existing company-owned-insurance and redemption arrangement should be reviewed rather than assuming the redemption obligation automatically offsets the insurance proceeds for federal estate-tax valuation.

A careful review should examine:

Whether the company or individual owners own the policies.
Who is the beneficiary.
Whether the agreement uses an entity redemption, cross-purchase, or hybrid structure.
How the purchase price is determined.
Whether the agreement’s valuation procedures are current and consistently followed.
How the insurance proceeds interact with the stated valuation method.
Whether the arrangement still aligns with each owner’s broader estate and tax plan.

Because Connelly involved a closely held corporation and federal estate-tax valuation, owners should avoid casually extending its holding to every LLC, every policy, or every tax question. The business’s legal form and tax classification matter, and restructuring insurance can create additional legal, tax, and practical consequences.

Where should the terms live?

For a Colorado LLC, buy-sell terms are often placed directly in the operating agreement or coordinated with it through a separate agreement. For a corporation, they are commonly included in or coordinated with a shareholder or stock-purchase agreement. Buy-sell provisions may also appear in partnership or other ownership agreements, according to this summary of common document structures.

A separate agreement can work, but all governing documents should use consistent definitions, voting requirements, transfer restrictions, and valuation rules. The review should include:

The operating, shareholder, or partnership agreement.
Any separate buy-sell or stock-purchase agreement.
Articles, bylaws, and amendments.
Employment and deferred-compensation agreements.
Insurance policies and beneficiary records.
Promissory notes and security agreements.
Trust and estate-planning documents.
Prenuptial or postnuptial agreements affecting an owner.

A clause saying “transfers are prohibited” is not a complete buyout plan. Likewise, a life-insurance policy is not a substitute for contractual instructions identifying the buyer, price, timing, and transfer obligations.

A practical review checklist for Colorado owners

Bring the agreement, amendments, insurance records, current ownership ledger, and recent financial information to the review. Then ask:

Are all current owners actually parties to the agreement?
Are ownership percentages accurate?
Are death, disability, retirement, resignation, termination, divorce-related transfers, and bankruptcy addressed?
Does each trigger create an option or an obligation?
Who buys first: the other owners or the company?
Is the valuation method objective and workable?
When was the agreed value or formula last reviewed?
Does the agreement identify a valuation date and standard?
Is there enough funding for the likely purchase price?
What happens if insurance proceeds or cash reserves are insufficient?
Are installment obligations secured and documented?
Do policy ownership and beneficiary designations match the agreement?
Has an entity-owned life-insurance arrangement been reviewed after Connelly?
Do the business documents coordinate with each owner’s estate plan and marital agreements?
Does the agreement explain what happens to voting, management, distributions, and employment before the buyout closes?
Is there a clear dispute-resolution process?

Build the plan while everyone can still decide together

The best time to discuss an ownership transition is while the owners are working well together and can make balanced decisions. That conversation is not a prediction that someone will leave or that a family will face loss. It is a way to protect the company, create financial clarity for every owner, and make sure employees and families are not left guessing.

Fusion Legal & Tax helps Colorado business owners review and coordinate operating agreements, shareholder agreements, buy-sell terms, valuation procedures, insurance funding, and federal tax considerations. The right structure depends on the company and its owners, so any changes should be made only after reviewing the governing documents, insurance arrangements, and tax consequences together.
