Wealth transfer isn’t just about passing on money — it’s about preserving values, preparing the next generation, and avoiding unintended conflict. Yet even financially successful South African families fall into the same avoidable traps, and the cost is often measured in both rands and relationships.
Whether you’re a first-generation entrepreneur, a high-net-worth individual, or a family stewarding wealth across generations, sidestepping these ten mistakes goes a long way to ensuring a smooth transition. For the bigger picture on why family wealth so often fails to last, read this alongside our pillar guide on generational wealth transfer in South Africa.
Key Definitions
Situs tax
Tax levied by a foreign jurisdiction based on where an asset is located (“situs”). For example, US-listed shares are US-situs assets and can attract US estate tax for non-residents, regardless of where the owner lives.
Letter of wishes
A non-binding document that sits alongside a will or trust, explaining the reasoning behind decisions — particularly useful where heirs are treated differently.
Buy-and-sell agreement
A formal arrangement, usually funded by life cover, that sets out what happens to a business owner’s share on death or disability — a cornerstone of business succession planning.
Liquidity audit
A review of how much cash an estate can access to cover estate duty, executor’s fees, and bequests without being forced to sell assets the family wants to keep.
The 10 Mistakes at a Glance
The detail matters, but here is the quick version — the ten mistakes and the fix for each.
| The Mistake | The Fix |
|---|---|
| 1. Delaying the conversation | Talk openly about intentions and values, not just numbers |
| 2. Outdated wills and plans | Review every 3-5 years or after any major life event |
| 3. Tax-inefficient structuring | Use appropriate trusts, endowments, and giving structures |
| 4. No liquidity plan | Run a liquidity audit; earmark cash or cover for estate costs |
| 5. No business succession plan | Buy-and-sell agreements, management training, a transition roadmap |
| 6. Assuming equal must mean fair | Use letters of wishes to explain differentiated decisions |
| 7. Ignoring cross-border issues | Check for separate wills, situs tax, and offshore heirs |
| 8. Neglecting the relational side | Capture values and intent in a family charter or legacy letter |
| 9. Assuming a trust solves everything | Keep the deed current, trustees capable, purpose aligned |
| 10. Leaving advice too late | Engage a multi-disciplinary team early |
The 10 Mistakes in Detail
1. Delaying the conversation until it’s too late
Too many families postpone estate conversations until someone dies or becomes incapacitated, which leads to confusion, conflict, and drawn-out administration. A 2023 Sanlam Wealth Index found that only around a quarter of South African high-net-worth individuals had discussed their estate intentions with their heirs.
The fix: Proactive, transparent communication. Host a family meeting to share your intentions and values — not just the numbers.
2. Failing to update wills and estate plans
Wills drafted a decade ago often don’t reflect current realities — new marriages, divorces, children, assets, or business structures. Even rapidly rising asset values can create unforeseen problems, such as a growing estate duty liability. One Cape Town entrepreneur died during the pandemic with no golden thread tying his will, family trust, and business together, leaving his wife to assemble the pieces of the puzzle with no picture on the box.
The fix: Review your estate plan every three to five years, or after any major life event. See our guide on why a valid will matters and how to structure one.
3. Structuring assets inefficiently for tax and estate duty
Investments and properties held in your personal name can result in unnecessary estate duty, capital gains tax, and executor’s fees.
The fix: Consider tax-efficient vehicles such as inter vivos trusts, endowments, or donations to Public Benefit Organisations, which can reduce your estate’s tax burden. Our estate planning guide covers the options in depth.
4. Not planning for liquidity
Many estates are asset-rich but cash-poor, with properties, farms, or shareholdings that can’t easily be liquidated. That forces heirs to sell valuable assets simply to cover estate costs.
The fix: Run a liquidity audit. Life cover, offshore cash reserves, or local investment portfolios can be earmarked for estate duty, executor’s fees, and bequests.
5. Overlooking business succession
If you own a business, who leads it when you’re gone? Without a succession plan, you risk the collapse of the business — and the family’s wealth with it. In one case, a Western Cape entrepreneur’s successful business effectively closed overnight: there was no one with authority to act, which triggered immediate contract losses and cash-flow problems, and the heirs had no management plan in place.
The fix: Formalise succession with buy-and-sell agreements, management training, and a clear transition roadmap for continuity.
6. Assuming all children should inherit equally
Equal isn’t always fair. One child might run the family business while another received support through university or a property deposit years earlier.
The fix: Use letters of wishes or a family charter to explain your decisions, and consider documenting past financial assistance or sweat equity.
7. Ignoring cross-border considerations
Modern families are global, but many still hold only a South African will — which creates significant complications where there are foreign assets or heirs living overseas.
Foreign assets and the “one will” problem. Even holding Apple or Tesla shares through a global platform can trigger situs tax and probate in the US. These are US-situs assets, and for non-residents they can attract US estate tax of up to 40% on the value above a US$60,000 threshold. Your executor may also need to initiate probate in the US, delaying distributions and adding cost. The same applies to UK property, EU bank accounts, or Australian retirement funds, none of which fall under a South African will unless explicitly addressed.
The UK non-dom changes. The UK has scrapped its long-standing “non-dom” regime. Since 6 April 2025, longer-term UK tax residents are taxed on worldwide income and gains, regardless of where the funds sit. That directly affects South African families with offshore life-wrapped investments, foreign trusts or endowments, or global share portfolios — particularly where an heir lives in the UK.
The fix: Review whether you need separate wills in other jurisdictions, and work with a cross-border fiduciary team so your global estate is structured to avoid probate delays, tax leakage, and double taxation.
8. Neglecting the emotional and relational side
Wealth can unite or divide. When inheritance expectations go unspoken, even close families can fall into conflict.
The fix: Create a family charter or legacy letter that communicates your values, vision, and the intent behind your decisions. It builds understanding across generations in a way a will never can.
9. Assuming a trust will solve everything
Trusts are powerful, but they aren’t silver bullets. Poorly managed or outdated trusts can trigger adverse tax consequences, fall foul of legislation, or simply lose the family’s trust — pun intended.
The fix: Keep the trust deed current, ensure trustees are capable and genuinely independent, and check that the trust’s purpose still aligns with your goals. See our guide to using family trusts effectively.
10. Leaving professional advice too late
Too many families rely on generic wills or cookie-cutter advice from professionals who don’t specialise in estate structuring or cross-border tax.
The fix: Engage a multi-disciplinary team — fiduciary, legal, tax, and financial planning — to build a custom, future-proof plan. For one practical example of where good advice matters, see our guide on helping your child settle their home loan without triggering donations tax.

Frequently Asked Questions
What is the most common wealth transfer mistake?
Delaying the conversation. Families often avoid discussing estate intentions until a death or incapacity forces the issue, which leads to confusion, conflict, and slow administration. The single highest-leverage step is an open family conversation about intentions and values while the wealth creators are still able to lead it.
How often should I update my will and estate plan?
Every three to five years as a baseline, and immediately after any major event — a marriage, divorce, birth, death, business sale, or a significant change in assets or residency. An outdated will is one of the most common and most avoidable causes of estate disputes.
Do I need a separate will for offshore assets?
Often, yes. Foreign assets — including US-listed shares, UK property, or offshore accounts — can fall outside a South African will and may trigger situs tax and foreign probate. A cross-border review will tell you whether separate jurisdictional wills are needed and how to avoid double taxation and delays.
Should all my children inherit equally?
Not necessarily. Equal and fair aren't always the same thing, especially where one child runs the family business or another received earlier financial support. A letter of wishes or family charter lets you explain differentiated decisions, which greatly reduces the risk of resentment and disputes.
Will setting up a trust protect my family's wealth on its own?
No. A trust is a powerful tool, but only if it's properly run — with a current deed, capable and independent trustees, and a purpose still aligned with your goals. A trust that exists on paper but functions as an extension of personal finances can create more problems than it solves.
Final Word
Successful wealth transfer isn’t really about who gets what. It’s about making sure your life’s work benefits the people and causes you care about — without confusion, delays, or disputes.
Almost every mistake on this list traces back to the same three things: planning early, communicating clearly, and structuring wisely. None of them require enormous wealth to get right — they require intention, and a willingness to have the conversations most families put off.
If any of these ten feel uncomfortably familiar, that discomfort is usually the signal to look again — while the people who built the wealth are still there to shape how it passes on.
Recognise a few of these in your own situation? We help families pressure-test their estate and succession plans — the structures, the liquidity, and the conversations — so wealth passes on cleanly. If that’s worth a discussion, we’re happy to talk it through.
