If you are the sole owner of your business, there is no co-owner waiting to buy your interest if you die. A multi-owner cross-purchase or entity-purchase structure is built around existing partners - not around a single owner with no internal buyer already on the cap table.
A one-way buy-sell arrangement (often searched as a unilateral buy-sell agreement) is the continuity pattern many sole owners explore: identify a prospective purchaser in advance, have counsel draft purchase and transfer terms, establish value with a qualified valuation professional, and - when appropriate - explore life insurance as a death-triggered funding tool so cash may be available toward that purchase path.
"One-way buy-sell" is often clearer than contract-law jargon. The exact legal form depends on an attorney-drafted agreement and on state and entity law. It is not a distinct statutory product type with one universal template.
This guide is educational only - not legal, tax, valuation, or insurance advice. Gary Cosby is a licensed life insurance agent, licensed in all 50 U.S. states. His role is the life-insurance funding component for death-triggered purchase obligations under an attorney-drafted arrangement. He does not identify buyers, draft agreements, set appraisals, design estate succession, or finance lifetime buyouts.
Key Takeaways
- A one-way (unilateral) buy-sell arrangement is commonly used when a sole owner wants a pre-identified purchaser - often a key employee, family member, or other appropriate party
- Life insurance, when used, is typically aimed at death-triggered funding only; disability, retirement, and voluntary exit need separate design
- A common pattern is for the intended purchaser to own a policy on the owner and be named beneficiary - subject to insurable interest, underwriting, policy terms, attorney-drafted obligations, and tax/legal review. That pattern is not mandatory
- Funding is contingent: the policy must be in force, terms and claim requirements must be met, and proceeds depend on the carrier's claims-paying ability. Insurance does not "guarantee" a buyout
- An attorney addresses purchaser/seller/estate obligations, triggers, transfer restrictions, lifetime-sale terms, consents, and enforceability - counsel may address these topics; this article is not a mandatory clause checklist
- A qualified valuation professional supports formal value; Gary does not set price. Coverage conversations follow professionally established need
- What happens to heirs or a spouse without a plan depends on entity type, governing documents, estate plan, and state law - outcomes are not automatic
- After counsel drafts the agreement and valuation is addressed, Gary can explore death-triggered life-insurance funding via business life insurance, coordinated with your CPA and attorney
What Is a One-Way (Unilateral) Buy-Sell Arrangement?
A buy-sell agreement is a legal contract that governs what happens to an ownership interest when defined events occur. A one-way design is the version sole owners often use: one designated party has a defined right and/or obligation to purchase the owner's interest on terms counsel drafts.
In practical terms, the arrangement can give employees, family, and stakeholders a clearer path for how ownership might transfer if the owner dies - when the agreement, funding, and estate documents are coordinated. It is not a substitute for a will, trust, or full succession plan. For broader exit context, see developing a succession plan and exit strategy and buy-sell planning.
A common (not required) funding pattern for death: the intended purchaser may own a life insurance policy on the sole owner and be named beneficiary, then use proceeds toward the purchase from the estate under the agreement. Whether that structure fits depends on insurable interest rules, underwriting, policy ownership and beneficiary design, tax treatment, and the attorney-drafted purchase obligations. Confirm design with counsel and a tax professional.
This differs from cross-purchase (co-owners buy each other out) and entity-purchase / stock redemption (the business redeems the interest). Those multi-owner structures assume more than one existing owner. A sole owner typically needs a different buyer identification and a one-way design rather than owner-to-owner cross policies - not because multi-owner tools are "impossible," but because the ownership structure is different. Dedicated articles cover cross-purchase, stock redemption, and business partner buyout themes. Owners coordinating a wider handoff may also review related succession and exit-planning educational content, while the attorney remains responsible for the one-way agreement and Gary remains limited to death-triggered life-insurance funding.
Who Often Considers a One-Way Arrangement?
- Sole owners without a business partner who want a pre-identified purchase path
- Businesses with a key employee or manager who could step into ownership if terms and funding are workable
- Owners whose family members may or may not want to operate the company - readiness varies by situation
- Owners coordinating continuity documents as part of a broader buy-sell plan conversation or business succession and exit planning
Fit is fact-specific. Counsel, valuation, tax, and insurance roles should stay separate. Broader succession or exit-planning education does not replace your attorney, valuation professional, or CPA, and Gary's role remains death-triggered life-insurance funding only.
Why Sole Owners Explore One-Way Continuity Planning
Without a written purchase path, what happens to the business interest after death is driven by entity documents, estate planning instruments, and state law - not by a single universal default. In some situations, interests may pass to a spouse or heirs through the estate. In others, operating agreements, shareholder agreements, or licensing rules shape who can own or operate the company. Outcomes can include continued family ownership, a negotiated sale, outside management, winding down, or other paths - none of which is automatic for every business.
Families and employees may face uncertainty about who controls the company, how value is determined, and where cash comes from if a sale is expected. That uncertainty is one reason owners work with an attorney and a valuation professional before they talk about insurance amounts.
Licensing and professional-practice rules can also matter in some industries and states. Whether an unlicensed heir can operate, even briefly, is a legal and regulatory question for counsel - not something an insurance article can settle with one example.
A one-way arrangement does not erase every risk. It can, when properly drafted and funded for the death path, give the estate and the intended purchaser a clearer contractual framework than improvising after a death.
How a One-Way Buy-Sell Arrangement Often Works
Mechanics vary by entity type and counsel's drafting. A typical planning sequence looks like this:
- Identify a prospective purchaser. Often a key employee, family member, or other appropriate party willing and able to take on ownership under defined terms.
- Attorney drafts the agreement. Counsel may address purchase obligations, triggers, payment timing, transfer restrictions, lifetime-sale or right-of-first-refusal style terms, consents, and enforceability under applicable law. This is not a DIY checklist of "four required elements."
- Valuation professional supports formal value. Price or pricing method should be owned by a qualified valuation professional. Funding conversations follow that need; the insurance agent does not set the business price.
- Explore death-triggered life insurance when appropriate. If the design uses life insurance, ownership, beneficiary, amount, and premium responsibility should match the attorney-drafted purchase path and tax advice. Insurable interest and underwriting must be satisfied.
- Maintain and review. Policies must stay in force per their terms. Reviews matter after ownership, valuation, insurability, or agreement changes - see buy-sell planning.
- At a covered death. If a valid claim is paid, proceeds may provide liquidity toward the contractual purchase. Closing mechanics stay with counsel and the estate's representatives.
There is no single numeric example that fits every firm. Valuation, ownership percentages, and policy design are case-specific and belong with the valuation professional, attorney, and CPA.
What Counsel and Valuation May Address (Not a Mandatory Checklist)
An attorney-drafted one-way arrangement may cover topics such as:
- Triggering events. Death is the path life insurance typically funds. Disability, retirement, divorce, or voluntary exit - if included - usually need separate terms and often separate funding analysis.
- Purchase price or valuation method. Fixed price with update cadence, formula, or independent appraisal at trigger are common approaches counsel and valuation advisors discuss. Stale fixed prices can drift from reality.
- Transfer restrictions and lifetime sales. Terms that limit sales to outsiders or require offering the interest to the designated purchaser first are drafting choices, not universal mandates.
- Funding and premium obligations. If life insurance is part of the design, the agreement may allocate who must keep coverage in force. A lapse can leave the contractual promise without matching cash.
- Estate and entity coordination. How the purchase interacts with wills, trusts, operating agreements, and spousal rights is counsel's lane.

One-Way vs Cross-Purchase vs Entity-Purchase
| Structure | Typical buyer | Typical ownership context |
|---|---|---|
| One-way / unilateral | A pre-identified purchaser (e.g., key employee, family member) | Often sole owner or single dominant owner |
| Cross-purchase | Remaining co-owners | Two or more active owners |
| Entity-purchase (redemption) | The business entity | Multi-owner entities where company-level redemption fits |
| Wait-and-see / hybrid | Path elected per counsel's design | Multi-owner businesses wanting flexibility |
If you already have business partners, cross-purchase or entity-purchase designs are usually the starting point - see cross-purchase and stock redemption. Sole owners more often need a one-way purchaser identified outside the current owner group. Structure choice is a legal decision; insurance follows the death-funding design counsel and advisors select.
Funding the Death-Triggered Purchase With Life Insurance
An agreement without a realistic funding path can leave the estate and the purchaser negotiating under cash pressure. Life insurance is often considered for death-triggered liquidity because a death benefit may become payable when the insured dies while coverage is in force - subject to policy terms, claim requirements, and the issuing carrier's claims-paying ability.
Life insurance does not:
- Guarantee that buyout money will be there in every scenario
- Deliver cash "exactly when needed" in all cases (contestability, claim review, ownership errors, and lapses can delay or defeat payment)
- Fund disability, retirement, or voluntary exit by itself
Compare common alternatives for death funding (each with tradeoffs counsel and a CPA should weigh):
- Personal or business savings - requires cash already accumulated before an unpredictable death
- Loans - depend on credit, collateral, and approval timing
- Installment notes - stretch payments over time and leave the estate exposed to the buyer's future performance
Typical Policy Themes (When Life Insurance Is Used)
In many one-way designs that use life insurance for death:
- The designated purchaser (or another owner structure counsel designs) may own the policy
- That party may pay premiums as the agreement and advisors specify
- Beneficiary designations are aligned so proceeds can support the contractual purchase path
Tax treatment of premiums and death benefits is fact-specific and depends on the ownership structure and other circumstances. Confirm the intended tax treatment with the business's CPA or tax attorney rather than relying on a general blog summary.
Disability and non-death triggers need separate analysis and often separate products or payment designs. Life insurance is not a stand-in for disability funding. Gary's lane here remains death-triggered life insurance, not disability product licensing narratives.

Frequently Asked Questions
What does "unilateral" mean in a unilateral buy-sell agreement?
In this business context, "unilateral" or one-way usually means a sole owner (or single dominant owner) designates one purchaser path rather than co-owners trading reciprocal buyout rights. It is not the same lesson as contract-law "unilateral contracts" (for example, reward-for-performance analogies). Prefer the phrase one-way buy-sell arrangement; the binding form is whatever counsel drafts under applicable law.
Is a one-way buy-sell arrangement legally binding?
When properly drafted, executed, and enforceable under applicable state and entity law, it can be a binding contract. An attorney should handle drafting and execution formalities. Insurance policies are separate contracts with their own terms.
Can multi-owner businesses use a one-way design?
Sometimes a dominant-owner or key-person path is drafted in multi-owner settings, but classic multi-owner continuity more often uses cross-purchase, entity-purchase, or hybrid structures. Sole owners are the usual audience for a pure one-way purchaser design. Structure choice belongs with counsel.
How much life insurance might be considered?
Coverage discussions should follow the agreement's valuation framework and a qualified valuation professional's work - with room to revisit as the business changes. The agent does not invent the price of the company. Periodic reviews help keep face amounts and legal terms from drifting apart.
What if the designated purchaser stops paying premiums?
If the design depends on a policy staying in force, a lapse can leave the purchase obligation without matching death-benefit liquidity. Counsel may address premium responsibility and remedies in the agreement; monitoring is part of ongoing buy-sell planning. Alternatives if someone is uninsurable or coverage lapses are legal and financial design questions - not something life insurance alone solves after the fact.
Do I need an attorney before talking about life insurance?
Yes for the agreement and often for sequencing. Legal structure, valuation method, and tax posture should lead. After the attorney establishes the arrangement and valuation is addressed, a licensed agent can explore death-triggered life-insurance funding. Start funding conversations in context at business life insurance, and keep counsel and your CPA in the loop.
Next Steps
- Speak with a business or estate attorney about whether a one-way purchase path fits your entity and family situation.
- Engage a qualified valuation professional for a usable value framework.
- Have your CPA review tax and basis implications of the proposed design.
- When the death-triggered obligation and value need are clear, contact Gary Cosby to explore life-insurance funding options through business life insurance.
