Shareholder Protection for International Businesses: What Happens if a Partner Dies?

For business owners with partners, a question that is easy to defer but dangerous to ignore: what happens to the business if one of you dies or becomes seriously ill?

Without planning, the answer is often chaotic. The deceased partner's shares pass to their heirs. Those heirs may want to sell. They may want a say in how the business is run. The surviving owners may want to buy the shares but lack the funds to do so immediately. What should be a manageable succession event can become a protracted dispute that damages the business, its staff and its clients.

Shareholder protection is the structured solution. It combines insurance — to fund a buy-out — with a legal agreement that creates a clear process when the triggering event occurs. This guide explains how it works, how it is structured for international businesses, and why it is one of the most overlooked areas of business planning for internationally mobile entrepreneurs.

The Risk That Most Business Owners Underestimate

Ask most business owners whether they have a will. Many will say yes. Ask whether their business has shareholder protection. Far fewer will say yes.

The oversight is understandable. Shareholder protection involves thinking about your own death or serious illness, coordinating with business partners, engaging lawyers and insurers simultaneously, and reviewing the arrangement regularly. It is easy to defer.

The consequences of deferral can be severe:

Forced sale: if the estate of the deceased needs liquidity and the surviving shareholders cannot buy them out, a sale of the whole business may be the only option — potentially at a poor price and at a time not of anyone's choosing.

Unwanted new shareholders: a deceased partner's spouse, adult children or other heirs become shareholders. They may have no business experience, different risk appetites, or simply wish to extract value as quickly as possible. The dynamics of the shareholder group change fundamentally.

Disputes over valuation: without a pre-agreed mechanism, the estate and the surviving shareholders may dispute what the shares are worth. Legal proceedings delay everything and cost money.

Loss of key relationships: in many businesses, the departing partner's client relationships, supplier contacts or technical expertise are personally held. The business needs time and resources to cope — precisely when it is being disrupted by the shareholder transition.

How Shareholder Protection Works

The structure has two components that must work together: the insurance and the legal agreement.

The Insurance Component

Each shareholder takes out a life (and typically critical illness) insurance policy on their own life. The sum assured should reflect the value of their shareholding. The policy is typically written in trust for the other shareholders — so that on death, the benefit is paid to the surviving shareholders rather than to the deceased's estate.

Policy ownership in trust: the trust structure is important. If the policy is not written in trust, the payout may form part of the deceased's estate, passing through probate and potentially attracting inheritance tax (UK) or equivalent estate taxes, and being delayed by the probate process. Writing the policy in a business trust (or a specially designed shareholder protection trust) keeps the funds outside the estate and available to the surviving shareholders promptly.

The Cross-Option Agreement

The insurance alone is not sufficient. Without a legal agreement connecting the insurance payout to the share transfer, the surviving shareholders have money but no obligation to buy — and the estate has shares but no obligation to sell at a specific price or on a specific timeline.

A cross-option agreement creates:

• A put option for the estate: the right (but not the obligation) to require the surviving shareholders to buy the shares at the agreed price
• A call option for the surviving shareholders: the right (but not the obligation) to require the estate to sell the shares at the agreed price

When both options are triggered (as they typically are simultaneously), the transaction completes. The share transfer and the insurance payment are coordinated, the estate receives fair value for its shares, and the surviving shareholders acquire full control.

Why cross-option rather than compulsory buy-back? A compulsory buy-sell arrangement (a "shotgun clause") may inadvertently create a pre-sale agreement for IHT or CGT purposes, potentially eliminating Business Relief (formerly Business Property Relief) on the shares. The cross-option structure, properly drafted, preserves Business Relief eligibility. HMRC have accepted this approach when the options are not both mandatory.

Valuation Mechanisms

The cross-option agreement must specify how the shares are valued at the point of the triggering event. Common approaches:

Fixed valuation: a pre-agreed figure, typically the value at the time the agreement was set up. Simple but risks becoming outdated.

Formula valuation: a multiple of the latest audited profits (EBITDA, EBIT or net profit), or net asset value per the last audited accounts. Transparent and objective, but the chosen multiple should reflect industry norms.

Independent expert: an appointed chartered accountant or business valuer determines the price at the time of the event. Fair but can be slow and expensive.

Agreed annual review: the shareholders meet annually (or at each share class review) and record an agreed valuation. This is written into the agreement and resets the basis annually. Simple to operate if the shareholders have a good working relationship.

The most important thing is to agree a mechanism — any reasonable mechanism — in advance. Disputes about valuation at the time of a shareholder's death are destructive and avoidable.

---

Critical Illness Cover

Many shareholder protection arrangements extend to critical illness — covering the shareholder if they are diagnosed with a qualifying serious illness (typically heart attack, stroke, cancer and other specified conditions), even if they survive. Critical illness can be equally disruptive to a business: the shareholder may need to step back for months or years, during which time their continued shareholding creates uncertainty.

Critical illness cover under a shareholder protection arrangement typically triggers the same buy-out mechanism as the life cover, but with additional complexity — the shareholder is still alive and may recover, making the permanent transfer of shares more sensitive. Specialist advice is needed on the structure of critical illness provisions.

International Business Considerations

For businesses with shareholders in multiple jurisdictions — which is common among globally mobile entrepreneurs — shareholder protection structures need to account for:

Governing law of the agreement: the cross-option agreement should specify which jurisdiction's law governs it. This matters most if shareholders are resident in different countries and the agreement needs to be enforced.

Insurability across borders: life insurance is generally available to individuals in most major jurisdictions, but policy terms, critical illness definitions, and underwriting standards vary. Obtaining cover for a UK-resident shareholder on one hand and a UAE-resident shareholder on the other may require policies from different insurers under different terms.

Corporate structure: where the business is held in a company in one jurisdiction (e.g., a UK limited company) but shareholders are resident elsewhere, the cross-option agreement should be governed by the law of the company's jurisdiction whilst also being consistent with the shareholders' own estate planning in their country of residence.

Inheritance and succession laws: forced heirship rules in some countries (France, many civil law jurisdictions) give surviving spouses or children mandatory rights to portions of an estate, which can override a shareholder agreement or will. Legal advice in each relevant jurisdiction is essential.

Tax treatment of policy proceeds: in the UK, the lump sum paid under a shareholder protection policy written in trust is generally free of income tax when received by the surviving shareholders, and outside the deceased's estate for IHT purposes. Other jurisdictions treat insurance proceeds differently.

Trust Structures and Business Trusts

The most common trust arrangement for shareholder protection in the UK is a business trust (sometimes called a shareholder protection trust or a relevant life policy trust). The policy is written into this trust, with the surviving shareholders as beneficiaries.

Alternative structures:

• Discretionary trust: where the trustees have discretion over the distribution of the insurance proceeds. Can be flexible but adds complexity.
• Absolute trust: where the beneficiaries are fixed. Simpler but less flexible if the shareholder group changes.

The trust structure must be consistent with the cross-option agreement. If a shareholder dies, the trustee releases the insurance proceeds to the surviving shareholders, who use them to fund the share purchase. This should be coordinated to happen quickly and with minimum friction.

Reviewing the Arrangement

Shareholder protection is not a "set and forget" arrangement. It requires regular review because:

• Business value changes: if the business grows from £1m to £5m, the sum assured of each policy may become inadequate
• Shareholders change: if a new shareholder joins or an existing one leaves, the agreement and policies need updating
• Personal circumstances change: marriage, divorce, children, change of residency — all affect how trust documents should be drawn
• Insurance terms change: policies may be reviewed at renewal; terms may become less favourable as shareholders age

An annual review — ideally coinciding with the business's financial year end — is best practice.
