Going into a property partnership or a joint venture is much like a professional marriage. You have spent months scouting the right assets, crunching numbers on an SPV structure and aligning your investment goals. When you step back and look at what you have built, the most critical element is almost always the least protected: the people behind it.
If your co-director or JV partner passes away without a formal agreement in place, those shares or ownership interests do not just vanish. They usually pass to the next of kin. Suddenly you are not in business with your trusted partner. You are in business with their bereaved spouse or children, who may know nothing about property and simply want their capital back. This often leads to forced asset sales at the worst possible time, destroying the very portfolio you worked so hard to build.
The fix is to professionalise your setup at the same time as your SPV. By combining a legal agreement with a tailored insurance policy, you ensure that if the unthinkable happens, the surviving partner has the funds to buy out the deceased partner's family.
What happens to your SPV shares on death?
In a standard limited company SPV, shares are personal property. If a shareholder dies, those shares become part of their estate. Unless your articles of association or a specific shareholders' agreement say otherwise, the legal title passes to the executors named in the will.
Without a plan, you face two major risks:
· Loss of control: beneficiaries may want to involve themselves in day-to-day decisions or block financing moves.
· Capital pressure: the family may demand an immediate buyout. If the company's cash is tied up in bricks and mortar, you may have to sell properties in a down market just to settle the debt.
The cross-option agreement: your legal blueprint
A cross-option agreement is the foundation of partnership protection. It is a simple legal contract between you and your business partners that creates two options:
· The call option: the surviving partners have the right to buy the deceased partner's shares.
· The put option: the deceased partner's estate has the right to force the surviving partners to buy those shares.
Crucially, this is not a binding contract for sale at the moment of signing. That distinction is vital for tax purposes, because it is an option only exercised after death. This usually allows the shares to qualify for Business Property Relief.
From 6 April 2026 the rules for BPR changed significantly. The 100% relief is capped at a combined £2.5m allowance per individual across business and agricultural assets. Any value above that threshold receives only 50% relief. For property investors there is an even bigger hurdle: HMRC generally views property letting as an investment rather than a trade, so most BTL SPVs do not qualify for BPR at all. This makes having the cash ready via insurance even more critical, as your estate will likely face a full 40% inheritance tax bill on your share of the portfolio. Tax rules change. Always confirm the current position with a qualified tax adviser.
How the policy funds the buyout
A legal agreement is useless if you do not have the cash to back it up. That is where shareholder protection insurance comes in. Each partner takes out a life insurance policy equal to the value of their interest in the business, usually written under trust for the benefit of the other partners.
If a partner dies, the policy pays a tax-free lump sum directly to the surviving partners. They use that cash to exercise their call option and buy the shares from the estate. The family receives a fair market price in cash. You retain 100% control of the property SPV.
Why you must set this up early
Investors often say they will get around to the insurance once the first few refurbishments are done. That is a mistake. Setting up business protection at the point of incorporation is much easier:
· Valuation clarity: easier to agree on a valuation formula when the business is fresh.
· Underwriting: you are likely younger and healthier now. Getting cover early locks in better rates.
· Lender confidence: a robust partnership agreement de-risks the key person element of the deal, which can help with complex financing.
Interaction with inheritance tax planning
Most investment property does not qualify for BPR, but the way you structure protection can still save your family a fortune. By writing the insurance policies under a specific business trust, the payout itself usually falls outside your personal estate for IHT purposes. The money goes exactly where it is needed, the buyout, without being eroded by a 40% tax bill before it reaches the surviving partner.
Frequently asked questions
Does this apply to LLPs as well as limited companies?
Yes. For limited liability partnerships we call it Partnership Protection. The mechanics are slightly different because you are dealing with partnership interests rather than shares. The outcome of providing cash to buy out a partner is exactly the same.
What happens if the business value increases significantly?
Your protection should not be a set-and-forget task. Review your cover and your cross-option agreement annually or whenever you add a significant asset. Most policies allow for increases to keep pace with growth.
Can the company pay the premiums?
Sometimes. Depending on how the policy is structured, the company can pay the premiums. This needs careful handling to avoid a benefit-in-kind charge for the directors. We work with your accountant to find the most tax-efficient route.
What if my partner becomes critically ill?
We often suggest adding critical illness cover to the plan. If a partner suffers a major heart attack or stroke and can no longer contribute to the JV, the policy can pay out to fund a buyout while they are still alive. They get the funds they need for recovery while you maintain control of the assets.
