Shareholder Agreement on Death: What Happens to Company Shares?
When a shareholder in a private company dies, their shares become part of their estate. Without a cross-option agreement, those shares can pass to a family member with no business role — creating a difficult situation for everyone. Here is how to plan ahead.
The Problem: Shares in the Wrong Hands
What happens without planning
→ Shares pass to executors and then to the beneficiary under the will (or under intestacy rules if no will)
→ A spouse or child who has no involvement in the business becomes a significant shareholder
→ They can vote on resolutions, block decisions, and demand a seat on the board
→ Surviving shareholders cannot force a sale — they are stuck with an unwanted co-owner
→ The estate has a hard-to-value, illiquid asset that may be difficult to sell
→ Pre-emption rights in the company articles may require shares to be offered to existing shareholders — but the price and timing may not work for the estate
The solution: cross-option agreement + life insurance in trust
→ Estate gets cash at fair value for the shares promptly
→ Surviving shareholders get the shares they need to continue the business
→ Business Property Relief preserved (no binding contract for sale)
→ Life insurance policies in trust fund the buyout — lump sum paid before probate
How a Cross-Option Agreement Works
Agreement in place during lifetime
All shareholders enter into a cross-option agreement. Each shareholder simultaneously: (a) grants the other shareholders a CALL option — the right to buy their shares at a fair value within the option period after death; (b) grants their estate a PUT option — the right to require the surviving shareholders to buy the deceased's shares at the same fair value. Both options are exercisable only within the option period (typically 3–12 months). Critically, neither is an obligation to buy or sell — each is only an option.
Life insurance policies written in trust
Each shareholder takes out a whole-of-life or term life insurance policy on their own life, equal to the current value of their shares. The policy is written in trust for the other shareholders. On death, the life insurance pays out to the surviving shareholders before probate — they receive the cash they need to fund the purchase. Because the policy is in trust, it does not form part of the deceased's estate and is not delayed by probate.
Death of a shareholder
On death, the deceased's shares pass to the executor and then to the beneficiary under the will. The cross-option agreement is triggered. Either the estate exercises its put option (requiring the surviving shareholders to buy) or the surviving shareholders exercise their call option (requiring the estate to sell). The purchase price is the agreed fair value (set by the agreement or by independent valuation). The life insurance proceeds fund the payment.
BPR is preserved
Because neither party is obliged to complete a transaction at the date of death, the shares are not 'subject to a contract for sale' under s113 IHTA 1984 at the point of death. BPR (100% for unquoted trading company shares) applies. The estate receives full BPR on the shares — then receives fair value cash from the surviving shareholders after the option is exercised.
Cross-Option vs Buy-Sell: The BPR Difference
| Feature | Cross-option agreement | Buy-sell agreement |
|---|---|---|
| Obligation to buy/sell on death | No — each party has an option | Yes — binding obligation |
| Business Property Relief | Preserved (no contract for sale) | Potentially destroyed (contract for sale at death) |
| IHT risk on estate | Low — BPR applies; 0% IHT on qualifying shares | High — shares may attract 40% IHT if BPR lost |
| Practical outcome | Parties decide after death whether to exercise | Transaction proceeds automatically |
| Preferred for BPR-qualifying companies | Yes | No — avoid |
Valuing Unquoted Company Shares on Death
HMRC values unquoted company shares at their “open market value” at the date of death — the price a hypothetical willing buyer would pay a hypothetical willing seller. For a minority shareholding in a private company, this typically means a significant discount to the pro rata value (commonly 30%–50% discount for a minority share with no control).
The shareholder agreement should specify how shares are valued for cross-option purposes — typically: an agreed formula (e.g., a multiple of EBITDA or net asset value), or an independent valuation by a named class of accountant, or a default to HMRC open market value. A clear valuation mechanism avoids disputes between the estate and the surviving shareholders at a difficult time.
Because values change over time, life insurance cover should be reviewed every 2–3 years to ensure it matches the current value of the shares. Underinsurance means the estate receives less than fair value; overinsurance means premiums are wasted.
Frequently Asked Questions
What happens to company shares when a shareholder dies without a shareholder agreement?
Without a shareholder agreement (or relevant provisions in the company's articles of association), shares in a private company pass under the deceased's will or intestacy rules to their personal representatives (executors or administrators). The personal representative becomes a 'legal holder' of the shares but the actual beneficial owner is whoever the shares are left to under the will. The surviving shareholders cannot prevent this — shares are property of the estate. The new shareholder may have no business experience, no relationship with the surviving shareholders, and no interest in helping the company. They can attend general meetings, vote on resolutions (including to block decisions the directors want), and appoint a new director. They can also sell their shares to a third party — potentially an unknown buyer — subject to any pre-emption rights in the articles.
What is a cross-option agreement and how does it work on death?
A cross-option agreement (sometimes called a double option agreement) is a contract between the shareholders of a company. It gives: (1) the deceased's estate a PUT option — the right to require the surviving shareholders to buy the deceased's shares at a specified price within a set period after death; (2) each surviving shareholder a CALL option — the right to require the estate to sell the deceased's shares to them at the same price. Both options can only be exercised within the option period (typically 3–12 months after death). The critical feature of a cross-option agreement (as opposed to a binding buy-sell agreement) is that neither party is obliged to buy or sell — each has the right but not the obligation. This preserves Business Property Relief (BPR): HMRC accepts that where shares are subject only to cross-options (not a binding sale obligation at death), they are not 'subject to a contract for sale' and therefore continue to qualify for 100% BPR. The agreement is typically funded by 'own life in trust' life insurance policies — each shareholder takes out a policy on their own life, written in trust for the other shareholders, equal to the current value of their shares.
Why is a buy-sell agreement riskier than a cross-option agreement for BPR?
A buy-sell agreement (sometimes called a cross-purchase agreement or 'put and call' agreement) creates a binding obligation to buy and sell shares on death — not just an option. Under s113 IHTA 1984, property is excluded from BPR if it is 'subject to a contract for sale' at the date of death. HMRC's view is that a binding buy-sell agreement creates a contract for sale that is triggered by death. This means the shares do not qualify for BPR — 100% relief is lost, and the shares could be subject to 40% IHT on the estate's value above the nil-rate band. A cross-option agreement (where both parties only have an option, not an obligation) avoids this: there is no binding contract for sale until one party exercises their option after death. The Shareholders' Agreement should be carefully drafted by a solicitor experienced in business succession planning to ensure the cross-option structure is preserved.
Do I need to update my will if I have a cross-option agreement?
Yes. A shareholder agreement and a cross-option agreement operate independently from your will: (1) your will directs who inherits your shares if the cross-option is not exercised (e.g., if the surviving shareholders choose not to exercise their call option, or if there are no surviving shareholders); (2) your will appoints the executor who will deal with the shares during the option period — the executor needs the power and authority to enter into the sale under the cross-option; (3) if you want your spouse or family to inherit the shares rather than see them bought out, this should be addressed in both the agreement and the will. Your will should: give the executor express power to deal with company shares and exercise or not exercise rights under shareholder agreements; address what happens to the purchase price received under the cross-option (part of the residuary estate); and consider what happens if the company is insolvent at the date of death.
What happens to Business Property Relief if company shares pass to a surviving spouse?
Shares in an unquoted trading company that qualify for BPR (currently at 100%) are exempt from IHT on the first death whether they pass to a spouse or to other beneficiaries — the spouse exemption applies to surviving spouse transfers regardless of BPR. However, on the surviving spouse's death: (1) BPR is available on the shares if the surviving spouse has held the shares for at least 2 years and the company still qualifies; (2) the surviving spouse cannot double up the deceased's BPR with their own BPR — BPR on the surviving spouse's estate applies to the shares they own at their death. A key planning point: if shares pass directly to children, each child can qualify for BPR on their own holding after 2 years. This can be more efficient than routing through the spouse. A shareholder agreement and good estate planning work together to determine whether shares pass to the spouse, to children, or are bought by surviving shareholders.
Business Owners Need a Will That Works Alongside the Shareholder Agreement
Your will needs to give your executors the powers to deal with company shares and interact with the cross-option agreement. The WillSafe kit gives you the foundation — from £19.97 for England and Wales.
