Buying a Deceased Partner's Stake: Financing Options for Surviving Co-Owners

The First 72 Hours After a Partner's Death

The death of a business partner triggers obligations most surviving co-owners aren't prepared for. Operations need to continue. Bank accounts may have authorization issues. The deceased partner's family is dealing with grief and may soon have questions about the business, their inheritance, and their rights.

The clearest path through this situation depends on one document: a buy-sell agreement.

A buy-sell agreement (also called a buyout agreement or shareholder agreement) is a contract among co-owners that specifies exactly what happens to an ownership stake when an owner dies, becomes disabled, or wants to exit. A well-drafted buy-sell agreement answers: Who can buy the stake? At what price? On what terms? How is it funded?

If a buy-sell agreement exists and is properly funded (typically with life insurance), the buyout process is relatively straightforward. The life insurance proceeds fund the purchase, the estate is paid, and ownership consolidates with the surviving partner(s). Without a buy-sell agreement, the surviving partner is negotiating a business acquisition with a grieving family who just became involuntary co-owners of a business they likely know little about.

The Buy-Sell Agreement: How Funded Buyouts Work

The most common funding mechanism for buy-sell agreements is cross-purchase life insurance: each partner owns a policy on the other. When a partner dies, the surviving partner receives the life insurance proceeds and uses them to purchase the deceased partner's ownership stake from the estate.

For a two-partner business valued at $800,000, a cross-purchase structure means each partner holds a $400,000 life insurance policy on the other. Annual premium for a healthy 50-year-old on a 20-year $400,000 term policy runs $800-$2,000/year. Modest relative to the protection.

If the business has grown since the buy-sell was funded and insurance coverage is inadequate, the surviving partner faces a shortfall. The estate receives the insurance payout; the remaining balance must be financed through other means (SBA loan, installment payment to estate, or third-party sale).

Most small business attorneys recommend reviewing buy-sell agreement coverage amounts every 3-5 years as the business grows. An underfunded buy-sell creates almost as many problems as no buy-sell.

When No Buy-Sell Agreement Exists

Without a buy-sell agreement, the deceased partner's ownership stake passes through their estate to their heirs. The heirs (who may have no interest in, and no knowledge of, the business) now own a stake in it.

The surviving partner's options:

Negotiate a buyout with the estate. This is the most common outcome. The surviving partner approaches the estate (through the executor or administrator) and negotiates to purchase the inherited stake. Price is the central issue. The estate's interest is maximizing value; the surviving partner's interest is paying a fair price on workable terms.

A third-party business valuation is essential here. Both parties need a defensible number as the starting point. Expect 60-120 days for negotiation and closing, longer if the estate is complex or the heirs dispute the valuation.

Take on heir-partners. If the heirs want to retain ownership, the surviving partner becomes co-owner with the deceased's family. This rarely works long-term. Operating a business with uninvolved family heirs creates governance problems, distribution disputes, and eventual forced-sale pressure.

Force a full sale. Some operating agreements give surviving partners the right to trigger a full business sale if the deceased partner's stake isn't sold within a specified period. If no such provision exists, forcing a sale requires court action.

Do nothing. Not viable indefinitely. The heirs' rights accumulate, and deferred resolution typically leads to litigation or a distressed sale.

SBA 7(a) Financing for a Partner Buyout

SBA 7(a) loans can finance the buyout of a deceased partner's stake. The surviving partner is the borrower; the purchase is the acquisition of a business interest from an estate.

SBA requirements specific to partner buyouts:

The timing challenge in deceased-partner buyouts is probate. In most states, transferring business assets from an estate requires either probate court approval or (if the deceased had a trust or appropriate titling) a simplified transfer. SBA lenders generally won't close a loan on business assets still in probate. Clear title must exist first.

Probate timelines vary dramatically by state. Simple estates in states with streamlined probate processes can clear in 4-6 months. Complex estates with disputes, real estate, or federal estate tax implications can take 12-24 months. Get a probate attorney's timeline estimate before committing to an SBA financing path.

Financing Without SBA: Installment Payment to the Estate

When SBA financing is unavailable (because probate is unresolved, the business cash flow doesn't support debt service, or the timeline is impractical), an installment payment arrangement directly with the estate is the fallback.

This structure mirrors a seller-held note: the surviving partner pays the estate over time rather than in a lump sum at closing. The estate (and eventually the heirs) receive regular payments from the business's cash flow.

Key negotiation points with an estate:

Interim operating agreement. Who manages the business during the buyout period? The surviving partner typically takes full management control in exchange for personal liability for operating decisions.

Valuation date. Is the price based on the value at the date of death? At the date of the buyout agreement? This matters if the business has changed value in the intervening period.

Interest on deferred payments. The estate will expect interest on deferred payments, typically at AFR or market rate. Current AFR rates at irs.gov.

Guarantees. The estate may request a personal guarantee from the surviving partner on the installment obligation.

An estate attorney and a business attorney on each side are essential for this structure. An installment sale to an estate has estate tax implications, income tax implications for the heirs, and legal complexity that requires professional guidance at every step.

A Representative Deceased-Partner Buyout

Two business partners each owned 50% of a $1.2M landscaping company in Georgia. They had no buy-sell agreement.

When one partner died unexpectedly at 58, the surviving partner had no legal mechanism to purchase the 50% stake automatically. The deceased partner's spouse inherited the ownership stake. She had no interest in running the business but wanted fair value for her husband's share.

The surviving partner negotiated a buyout of the 50% stake ($600,000 at appraised value) over 14 months. Probate in Georgia took 11 months to clear title. Structure at closing: $280,000 paid from business cash reserves accumulated during the probate period, and a $320,000 installment note to the estate at 4.7% interest (long-term AFR at time of closing), 7-year term.

Total professional fees: probate attorney $12,000, business attorney $8,000, business appraiser $6,500. Total time from partner's death to closed buyout: 16 months.

Had a funded buy-sell agreement been in place, estimated time to completion: 45-60 days. Estimated professional fees: $3,000-$5,000.
