When Silence Costs Millions: Estate Planning Lessons for High Net Worth Families

IN THE COURT ROOM, A Fortune in Dispute

The Succession High  Court was unusually full that Tuesday morning. Word had spread through legal circles that the matter set for hearing — In the Matter of the Estate of the Late J.M.K. — involved not just a single parcel of land, but a business empire: four commercial properties in town, a fleet of matatus, shareholding in two private companies, a coffee farm in Subukia, and accounts held in three different banks.

J.M.K. had built all of this from nothing over four decades. He was, by any measure, a high net worth individual. What he did not have, when he died suddenly of a heart attack at 68, was a valid will.

What followed was two and a half years of litigation. A widow from his first marriage. A second wife married under customary law whose union was contested. Five adult children, two of whom had worked in the business for over a decade without any formal shareholding. A business partner holding 40% of the shares in one company, now uncertain who his co-director's estate representative would be. And a stalled coffee export contract worth several million shillings, frozen because no one had authority to sign on the estate's behalf.

This is not a hypothetical. It is a composite of the kind of matter that lands, with painful regularity, on my desk as a succession practitioner in Kenya. And it illustrates, better than any textbook chapter can, why estate planning for high net worth families is not a luxury exercise in paperwork — it is risk management for wealth that took a lifetime to build.

Why High Net Worth Estates Fail Differently

Ordinary estates can often limp through intestacy under the Law of Succession Act (Cap 160) without catastrophic damage. High net worth estates rarely have that luxury, for three reasons that played out directly in J.M.K.'s case.

First, complexity multiplies conflict. A single house can be divided or sold. A business cannot be split down the middle without destroying its value. When J.M.K.'s children and widow could not agree on whether to sell the commercial properties, lease them, or continue running them, the properties sat generating disputes instead of income while the matter dragged through court.

Second, the assets themselves become vulnerable during the vacuum. With no substitute director appointed and no clarity on estate representation, the company's bank could not process routine transactions. The coffee export contract lapsed. A tenant in one of the commercial buildings, sensing the confusion, simply stopped paying rent — and it took a separate suit in the Environment and Land Court, with all the delay that entails, to resolve occupation and rental arrears alongside the succession cause.

Third, family structure disputes become inseparable from asset disputes. Because J.M.K. left no will acknowledging his second wife or clarifying the status of children born to her, the court could not proceed to distribute a single asset until it had first determined, as a threshold issue, who qualified as a dependant and beneficiary under Sections 29 and 35 of the Law of Succession Act. Two years were spent essentially answering the question "who are the heirs?" before the court could even begin to answer "who gets what?"

The Legal Tools That Could Have Prevented This

Kenyan law offers high net worth families several instruments that, used properly, would have kept J.M.K.'s estate out of court entirely — or at least narrowed dramatically what remained to be contested.

1. A Properly Executed Will

A will drafted in compliance with Section 5 and 11 of the Law of Succession Act would have allowed J.M.K. to name an executor, specify how the business shares should be handled (including any right of first refusal for his business partner), and expressly provide for his second wife and her children — removing the need for the court to determine dependency status from scratch. Even a straightforward will, properly witnessed and stored, would likely have cut the litigation timeline by more than half.

2. Family and Discretionary Trusts

For assets like the commercial buildings and farm, a trust structure — whether a simple deed-based trust under Cap 285 or a fully incorporated trust under the Trustees (Perpetual Succession) Act (Cap 164) — would have kept those assets outside the probate process altogether. Trustees could have continued managing the properties and collecting rent without interruption the moment J.M.K. died, because legal title would already sit with the trust rather than with him personally. This is often the single most effective tool for high net worth families with income-generating property, and it is precisely the gap that caused the rental dispute in J.M.K.'s matter.

3. Buy-Sell and Shareholder Agreements

The uncertainty facing J.M.K.'s business partner was entirely avoidable. A shareholder agreement with a buy-sell clause, often funded by a life insurance policy on each shareholder's life, would have given the surviving partner a clear, funded mechanism to buy out the deceased's shares — or would have set out exactly how the estate's representative should step into governance in the interim.

4. Lifetime Gifting and Advancement Records

Two of J.M.K.'s children had worked unpaid or underpaid in the business for years, believing they were building an inheritance. Without documentation, the court was left to assess, largely on oral testimony, whether this constituted an advancement to be brought into account under Section 42 of the Act, or simply employment. Clear records — even informal letters or minutes — of lifetime gifts and advancements prevent exactly this kind of evidentiary battle.

5. Letters of Wishes and Family Governance Frameworks

Beyond the strictly legal instruments, many high net worth families now pair their wills and trusts with a letter of wishes: a non-binding but persuasive document explaining the reasoning behind asset division, expectations for children active in the business versus those who are not, and guidance for trustees exercising discretion. It will not bind a court, but it frequently prevents disputes from starting in the first place by removing ambiguity about intent.

What This Means for Your Family

If you have built a business, acquired property, or accumulated wealth across multiple assets and entities, the story above should feel uncomfortably familiar in its structure, even if the details differ. The good news is that everything that went wrong for J.M.K.'s family is preventable — but only if it is addressed while you are here to make the decisions yourself.

Here is where I would encourage you to start:

• Get a complete picture of what you actually hold. Most high net worth families underestimate how scattered their assets are — land here, shares there, a vehicle fleet, accounts in different banks, an interest in a business that was never formally documented. Before any plan can protect your estate, it needs to account for every piece of it. I work with clients to build this map as the foundation of any succession strategy.
• Choose the right instrument for each asset, not a one-size-fits-all will. Income-generating property is often best placed in a trust so it keeps running the day you are no longer there to manage it. A controlling shareholding needs a shareholder or buy-sell agreement, not just a mention in a will. Getting this matched correctly is where most self-drafted or template plans fall short.
• Resolve marital and family status questions now, not later. If your family includes more than one marriage, children from different unions, or informal arrangements that have never been legally regularised, this is the single most common source of the kind of multi-year dispute described above. Addressing it while you are alive is far simpler than leaving a court to determine it after you are gone.
• Review your plan as your life changes. A plan drafted a decade ago rarely still fits the estate you hold today. I recommend revisiting your will, trust, and shareholder arrangements whenever a business grows, a child joins the enterprise, or your family circumstances shift.
• Bring your family into the picture, on your terms. Disputes are driven far more often by surprise than by disagreement over substance. A well-prepared letter of wishes, discussed with your family in advance, does more to preserve both your wealth and your relationships than almost any other single step.

None of this needs to happen all at once, and it does not need to be uncomfortable. It simply needs to start with a conversation. If you recognise your own family's situation in any part of J.M.K.'s story, I would welcome the opportunity to sit down with you, review what you currently have in place, and help you build an estate plan that keeps your family out of the courtroom altogether.

Closing Thought

J.M.K.'s estate was eventually settled — through a consent order that took the family most of three years and a significant portion of the estate's liquidity to reach. The business survived, but diminished. The relationships within the family did not fare as well.

For high net worth families, the true cost of inadequate estate planning is rarely the legal fees of the eventual dispute. It is the years of frozen assets, strained relationships, and diminished enterprise value that accumulate while a court works through questions that a will, a trust, or a shareholder agreement could have answered in advance.

The most valuable estate plan is not the one that anticipates every possible dispute. It is the one that never has to go to court at all.
