Buying a Business With a Partner: Roles and Buy-Sell

Buying with a partner works best when you settle roles, ownership and exit terms in writing before you sign anything with a seller or a lender. Expect a lender, including a Small Business Administration (SBA) 7(a) lender, to ask each significant owner for a personal guaranty of the loan, and expect a buy-sell agreement to decide what happens when a partner dies, leaves or disagrees. This guide is for entrepreneurship through acquisition (ETA) searchers who partner up, friends buying together and operators teaming with a capital partner. It is general information, not legal or tax advice, so work with deal counsel and your accountant.

The short answer

Agree before you sign: roles, time, money in, ownership, decision rights, deadlocks and exits. Your attorney drafts the agreement.
Lenders look at every significant owner. In an SBA 7(a) loan, each person who owns 20% or more must give an unlimited personal guaranty, and a lender can ask others to sign too.
A buy-sell agreement sets the price and process when a partner dies, becomes disabled, divorces, goes bankrupt, quits or sells. Funding it with life insurance is common but not required, and the tax and structure choices belong with an estate or tax attorney.
Business insurance does not buy out a partner. Property, liability and business income policies do not fund a buyout or replace a partner. Key person and buy-sell funding are life and disability questions for a life insurance specialist.
Do pairs do better? No general rule. IESE Business School (IESE) says its search fund data support no general preference for pairs over solo searchers, so decide on roles and exit terms you can actually agree.

How can two or more people buy a business together?

There are many ways to structure a partnership, and the right one is a decision for your attorney and tax advisor. This table shows common setups at a general level and how each touches lending and insurance.

Common partnership setups and what each means for lenders and insurance
Setup	What it usually means	Lender and insurance angle
Equal co-owners who both operate	Two people share ownership and run the business together	Both likely own 20% or more, so in an SBA 7(a) loan each must give an unlimited full guaranty. Each is a key person, so a buy-sell plan matters.
Operator plus capital partner	One person runs the business and the other mainly supplies money	A non-controlling investor with under 20% and no control can count toward the SBA equity injection, within an SBA cap: limited sources like this together may cover no more than half of the required injection, and your lender confirms how it applies. A capital partner who owns 20% or more must give an unlimited guaranty, like the operator. The operator carries the day-to-day risk.
Co-searchers backed by investors	Two searchers raise search capital from investors, then buy and run one company	Investors often hold most of the board seats after the deal in the traditional model, which raises directors and officers (D&O) liability and investor reporting questions. See D&O for a search fund board.
Seller keeps a stake	A partial change of ownership where the seller stays an owner	The operating company and every new owner buying any interest must be co-borrowers. A selling owner who keeps under 20% must give a guaranty of the full loan for at least two years.
Holding company with investors	An entity owns the operating company and outside investors own the entity	An entity owning 20% or more also gives an unlimited guaranty. See insurance for holding companies and roll-ups.

One SBA caution: "multi-step" partial changes, where existing owners bring in a new owner by forming a new entity that becomes the 100% owner of the operating company, are not eligible. Ask your lender before you design the structure.

Do partners do better? IESE Business School's 2026 study of funds outside the United States and Canada found that 77.5% of concluded partnered searches ended in an acquisition, against 69.9% of concluded solo searches, but IESE says its data support no general preference for pairs. These are investor-backed search funds, not a forecast for your deal. For the model itself, see how search funds work.

What should partners agree on before they sign?

Most partnership trouble comes from questions nobody asked while everyone was friendly. Put each of these on the table and write down the answers. Your attorney turns them into the operating or shareholder agreement.

Roles and time. Who is the chief executive, who runs finance and operations, and how much time does each person commit? What happens if one person works much more than the other?
Money in. Who puts in how much equity, who gives a guaranty on which debt, and who covers a cash shortfall later? Are loans from partners treated differently from equity?
Ownership split. Does the split follow capital, effort, who found the deal, or a mix? Should some equity be earned over time? These are negotiating and tax questions, so ask counsel.
Decision rights. What needs both signatures: borrowing, hiring a senior person, signing a large contract, selling the business?
Deadlock. What is the process if you cannot agree, and who breaks the tie?
Pay. What does each partner draw, and how does that compare with the debt service your lender expects?
Exit. How is a partner's interest priced, who can buy it, and how fast must payment happen? That is the buy-sell agreement, covered below.

What do personal guaranties mean for each partner?

A guaranty is a personal promise to repay if the business cannot. SBA's rulebook makes this concrete:

Every SBA loan must be backed by a guaranty from at least one individual or entity. Any individual who directly or indirectly owns 20% or more of the borrower must give an unlimited full guaranty, and so must an entity or trust owning 20% or more. Ownership of spouses and minor children is combined.
A lender may ask others to sign too, such as a minority owner or a non-owner who is critical to operations. A six-month lookback applies to someone who recently owned 20% or more, and trusts add a further step, so ask your lender which rules apply to your group.

In an SBA initial acquisition by an individual, the business and the buyer are co-borrowers. How the co-borrower and guaranty rules apply across several buying partners is settled in the lender's documents, so read them with your attorney. In practice, expect the lender to ask each significant owner for a guaranty of the whole loan. How partners share that risk with each other is a question for counsel.

A hypothetical example. Two partners each buy 50% of a company with a $1,000,000 SBA loan. Each owns more than 20%, so SBA rules require both to sign an unlimited full guaranty. Depending on the documents, each could be pursued for the whole balance and not just half. Then one partner dies. The lender still has the surviving partner's guaranty, the business has lost a key person, and the question of whether the survivor can buy the estate's share depends on whether a buy-sell agreement exists and how it is funded. Neither the business's liability policy nor its property policy answers any of those questions.

A guaranty makes the person who signs it personally liable. Business insurance policies insure the business against covered losses and do not pay the loan the owner personally backed. They can still matter indirectly, because a covered loss that keeps the business running protects its ability to repay. See insurance after an SBA acquisition loan. The full rules, and what they mean for your personal insurance, are in the guide on personal guaranties and personal insurance, listed under Keep reading at the end of this page.

What is a buy-sell agreement and how is it funded?

A buy-sell agreement is a contract among the owners that continues the business by requiring an owner's interest to be sold on a triggering event at a price set in advance, either fixed or by formula. It is often funded by life insurance, though funding is not needed for the agreement to be valid.

Practitioners describe four common structures. Tax and lender facts decide which fits, so ask your attorney and accountant.

Redemption (entity purchase): the company buys the departing owner's interest. Simple, but lender or creditor limits may apply.
Cross-purchase: the other owners buy it, each holding policies on the others. Three owners need six policies, four need twelve.
Hybrid: the company and the owners share the purchase.
Insurance LLC: a separate entity holds the policies.

Buy-sell triggers and the role of insurance
Trigger	What the agreement should answer	Insurance role
Death	Who buys, at what price and how fast the estate is paid	Life insurance is a common funding tool. A life insurance specialist can advise.
Permanent disability	How disability is defined and when a buyout starts	Disability coverage may be one way to fund it. Ask a disability specialist.
Divorce	Whether a spouse can end up an owner, and how the interest is bought back	None directly. Price and payment terms matter.
Quitting or leaving the job	Whether the owner must sell, and how fast	None directly. Often paid in installments.
Bankruptcy	Whether a creditor or trustee can take an interest	None directly.

Morrow is not a law or tax firm, so treat this list as background, not advice. Questions to bring to an estate or tax attorney and a life insurance specialist:

Is the structure a redemption or a cross-purchase?
How are the premiums and proceeds taxed?
How does the price affect estate tax value? The Supreme Court's 2024 decision in Connelly v. United States is one reason to ask.
What happens if term coverage becomes costly or lapses?
What notice and consent rules apply to employer-owned policies?

Ask these before you pick a structure.

What does business insurance cover when partners die, leave or disagree?

Be precise about what business insurance does. Property, liability, workers' compensation and business income policies protect the business against covered losses. Business income insurance responds to direct physical loss to property, not to the loss of an owner or a key person. None of them funds the purchase of a partner's interest. See business interruption when the owner was the business.

Key person insurance is life or disability insurance a business buys on a person whose death or absence could cost lost profit or the expense of finding a successor. A business generally cannot deduct premiums on a policy under which it is a beneficiary, and employer-owned policies have notice and consent rules that must be met before the policy is issued. These products are outside Morrow's commercial property and casualty focus, so ask a life insurance specialist and your tax advisor.
Lender life insurance. For a standard SBA 7(a) loan that is not fully secured, the lender must require life insurance equal to the collateral shortfall on principals of a business that depends on one owner's active participation, and lenders can require more under their own policy. That policy is usually assigned to the lender and the death benefit is normally applied to the loan balance, so it does not fund a buy-sell agreement. Plan separately for the buyout. See life and disability insurance and an acquisition loan.
Disputes between owners. Ask your broker whether the company has a management liability policy (which can include directors and officers, or D&O, coverage) at all, and whether it responds to a claim one owner brings against another. Some policies limit or exclude claims between insured people, so read the wording.
Ownership changes. A partner joining, leaving or being bought out can be an ownership change for workers' compensation, depending on the size of the interest and the state's rules. California's rating bureau, for example, treats a change as material only if the prior owners hold less than one-half afterward (check the current rating plan). In states that use National Council on Compensation Insurance (NCCI) forms, and in several states with their own bureaus, the policy requires you to report it to your insurer within 90 days when it applies, and the rating bureau decides how it affects your experience modification. Update the named insureds and signers on other policies at the same time.

A Morrow review can cover the property and casualty side: who is named on each policy, whether limits and liability coverage fit the business, and what to ask carriers about owners and officers. For the life and disability side, a life insurance specialist is the right person, working with your attorney on the buy-sell agreement.

Frequently asked questions

Should I buy a business with a partner or alone?

It depends on what you need. A partner can add skills, capital and a second person who can run the business, but you share decisions, equity and personal risk. IESE says its search fund data support no general preference for pairs over solo searchers. Decide on the roles and the exit terms you can actually agree.

Will each partner have to sign a personal guaranty?

For an SBA 7(a) loan, any individual who owns 20% or more of the borrower must give an unlimited full guaranty, spouses' ownership is combined, and the lender can ask others to sign too. Your lender's documents set the details, so review them with your attorney before signing.

What is a buy-sell agreement?

It is a contract among owners that sets the price and process for buying out an owner who dies, becomes disabled, divorces, goes bankrupt, quits or sells. It is often funded with life insurance, but funding is optional. An attorney should draft it, with tax advice on the structure.

Does my business insurance pay to buy out a partner?

No. Property, liability and business income policies protect the business against covered losses and do not fund a buyout. Business income insurance responds to direct physical loss to property, not to losing a partner. Buyouts are usually funded with life or disability insurance, so ask a life insurance specialist.

Does key person insurance help the business if a partner dies?

It can help the business pay for lost profit or the cost of finding a successor, depending on how the policy is written and owned. It is a life insurance product with its own tax and consent rules, so work with a life insurance specialist and your tax advisor.
