When it comes to planning your estate in South Africa, you have two primary legal instruments at your disposal: a will and a trust. Both allow you to direct what happens to your assets when you die (or during your lifetime). Both have legitimate and important roles in estate planning.
But they are not interchangeable, and choosing the wrong one — or neglecting to use both together — can cost your estate significantly in taxes, fees, and delays.
What Is a Will?
A will (formally a “Last Will and Testament”) is a legal document in which you set out your instructions for the distribution of your assets after your death. It is the cornerstone of any estate plan.
Key characteristics of a will:
- Takes effect at death — a will has no legal force while you are alive.
- Must be administered through the estate process — the executor is appointed, the Master of the High Court is involved, a Liquidation and Distribution Account is prepared.
- Becomes a public record — once lodged with the Master, a will becomes accessible to interested parties.
- Can be contested — heirs and interested parties may challenge the validity of a will in court.
- Can be simple or complex — a will can include a testamentary trust (a trust that comes into existence when you die) as part of its provisions.
What Is a Trust?
A trust is a legal arrangement in which assets are transferred to and held by trustees for the benefit of beneficiaries. Trusts can be created to serve many different purposes — protecting assets, managing wealth across generations, providing for minor children, or reducing estate duty.
In South Africa, trusts are governed by the Trust Property Control Act 57 of 1988 and are overseen by the Master of the High Court (which registers and regulates trusts).
Two Types of Trusts Relevant to Estate Planning
1. Inter Vivos Trust (Living Trust) Created and operative during your lifetime. You transfer assets into the trust now, and the trust holds and manages them according to the trust deed. The trust continues after your death — assets in the trust do not form part of your deceased estate.
2. Testamentary Trust Created within your will and only comes into existence when you die. Assets flow from your estate into the testamentary trust and are then managed by trustees for the benefit of beneficiaries (typically minor children until they reach a specified age).
Side-by-Side Comparison
| Factor | Will | Inter Vivos Trust | Testamentary Trust |
| When it takes effect | At death | During your lifetime | At death (via will) |
| Assets form part of estate? | Yes | No (if properly structured) | Assets pass through estate first |
| Subject to estate administration? | Yes | No | Yes (initially) |
| Estate duty exposure | Yes — full estate assessed | Reduced — assets outside estate | Yes — on assets before entering trust |
| Privacy | Limited — will is accessible to interested parties | Higher — trust deed is not publicly accessible in the same way | Limited initially |
| Setup cost | Low (legal fees to draft) | Higher (trust deed, registration, ongoing administration) | Moderate (within will drafting) |
| Ongoing costs | None (one-off document) | Annual trustee meetings, accounting, potential audit | Trustees’ fees and administration while trust operates |
| Control during your lifetime | None (takes effect at death) | Full (you can be a trustee) | None until death |
| Complexity | Low to moderate | Moderate to high | Moderate |
| Useful for minor children? | Yes (via testamentary trust clause) | Yes | Yes |
When a Will Alone Is Sufficient
For many South Africans, a well-drafted will is all the estate planning they need. A will is appropriate when:
- Your estate is straightforward — primarily South African assets, a modest estate, few complications.
- Your estate value is below the estate duty threshold — the R3.5 million abatement means estates up to this value are not subject to estate duty (with the Section 4(q) spousal exemption potentially sheltering far more).
- You have a surviving spouse — assets left to a spouse are exempt from estate duty under Section 4(q), so the duty liability is deferred.
- Your children are adults — no need for a protective trust structure to hold assets until they come of age.
- You do not have complex offshore assets or business interests — these typically benefit from trust structures.
A will costs relatively little to draft and has no ongoing maintenance costs. For many people, it is the right tool — and the only one they need.
When an Inter Vivos Trust Should Be Considered
An inter vivos trust makes sense in the following situations:
1. Your Estate Will Exceed the Estate Duty Threshold
Estate duty is levied at 20% on dutiable estates above R3.5 million (25% above R30 million). By transferring appreciating assets into an inter vivos trust during your lifetime, the future growth of those assets accrues in the trust — not in your personal estate. This reduces your estate duty exposure over time.
However, this requires careful planning: the transfer of assets to a trust may attract donations tax (at 20%, with an annual exemption of R100,000) and capital gains tax. The long-term estate duty saving must outweigh these entry costs.
2. You Have Minor Children
An inter vivos trust can be structured to provide for your minor children during your lifetime (if you become incapacitated) and after your death. Assets held in a trust for minor children are protected from mismanagement and do not fall into the estate administration process on your death.
3. Asset Protection
Assets held by a trust are generally protected from claims against you personally — including divorce claims (subject to limitations), business creditors, and sequestration. This is a legitimate estate planning and asset protection tool when structured correctly.
4. Business Continuity
If you own a business, holding it through a trust ensures continuity — the business is not wound up as part of your estate when you die, and trustees can manage it without interruption.
5. Offshore Assets
For estates with offshore assets, a trust structure may improve efficiency of administration and potentially reduce exposure to foreign estate or inheritance taxes.
When Both Are Needed
In most sophisticated estate plans, a will and a trust are used together:
- The inter vivos trust holds the major appreciating assets (property portfolio, business interests, investments) during your lifetime and continues after your death.
- The will deals with your personal assets not held in the trust (personal belongings, vehicles, remaining cash, life insurance proceeds paid to your estate).
- The will may also include a testamentary trust as a safety net for minor children who are beneficiaries — if you die before they come of age, their inheritance is managed by trustees rather than distributed outright.
This combined approach maximises estate duty efficiency, ensures continuity, and protects beneficiaries.
The Common Mistakes to Avoid
Funding the Trust Properly
A trust that holds no assets is useless. Many people set up an inter vivos trust but never transfer their assets into it. This is called an “empty trust” — it offers none of the benefits while still incurring setup and running costs.
Treating the Trust as Your Own Bank Account
For an inter vivos trust to be effective as an asset protection and estate duty planning tool, it must be administered as a genuine separate legal entity. This means: – Separate bank account – Trustee meetings with proper minutes – Formal resolutions for trust decisions – Trusts assets clearly distinguished from personal assets.
Blurring the line between trust and personal assets risks the trust being “pierced” — a court finding that it is not a genuine trust and including the assets in your personal estate.
Ignoring the Loan Account
When assets are sold to a trust (the recommended method to avoid donations tax and CGT on transfer), the trust owes you the purchase price, recorded as a loan account. This loan account is an asset of your estate at death. Proper planning includes a strategy for reducing the loan account over time.
Frequently Asked Questions
Is a trust more expensive to administer than a will?
Yes. A trust has setup costs (typically R15,000–R50,000 for a properly drafted deed and registration), annual administration costs (trustees’ fees, accounting, potential audit), and any tax associated with asset transfers. A will is a once-off cost. The trust is only cost-effective if the estate duty saving outweighs the ongoing costs — typically at estate values above R5–10 million.
Can I be a trustee of my own inter vivos trust?
Yes, in South Africa a founder can also be a trustee. However, you should not be the only trustee — the trust needs at least one independent trustee to be considered a genuine separate entity. Being both founder, trustee, and beneficiary of your own trust is scrutinised by SARS and the courts.
Does a trust avoid executor’s fees?
Assets held in an inter vivos trust at your death do not form part of your deceased estate and are therefore not subject to executor’s fees on those assets. This is an additional cost saving on large estates.
Can SARS challenge my trust?
SARS has become increasingly active in challenging trusts that appear to be vehicles for tax avoidance rather than genuine estate planning structures. A trust that is properly constituted, genuinely funded, and administered with formal trustee governance is far less vulnerable to challenge.
I already have a will. Do I still need a trust?
It depends on your circumstances — the size of your estate, your family structure, your business interests, and your estate planning goals. A consultation with an estate planning attorney will give you a clear picture of whether a trust adds sufficient value to justify the cost.
Make the Right Choice for Your Estate
The choice between a will and a trust is not binary — the right answer for most people is a properly drafted will, potentially combined with a trust when circumstances justify it. The catch is to be sure of the context and whether a trust is appropriate.
