Testamentary Trust for Minor Children in South Africa

When both parents die and the will does not include a testamentary trust, the minor children's inheritance is paid into the state-run Guardian's Fund. The money sits there until each child turns 18, earning modest interest, administered by an under-resourced government office, and accessible to the guardian only through a cumbersome application process for documented expenses. This is the default outcome — and it is entirely preventable.

A testamentary trust is a clause in your will that creates a trust upon your death, managed by trustees you choose, for the benefit of your minor children. It keeps the inheritance out of the Guardian's Fund, allows professional management and growth of the assets, and gives the trustees discretion to release funds for the children's needs throughout their minority.

How a Testamentary Trust Works

Unlike an inter vivos trust (created during your lifetime), a testamentary trust only comes into existence when you die. It is created by the will itself, governed by the Trust Property Control Act 57 of 1988, and registered with the Master of the High Court.

The will specifies:

• The trustees — who will manage the trust assets. Ask the Master or a trust practitioner whether an independent trustee is required for the proposed structure.
• The beneficiaries — your minor children, and potentially their descendants.
• The distribution rules — when and how the capital and income should be distributed. Common structures include income for maintenance during minority, capital released at 21 or 25 (or in tranches), and discretionary distributions for education, medical expenses, and emergencies.
• The termination date — when the trust winds up and distributes remaining assets outright.

Why Not the Guardian's Fund

The Guardian's Fund is administered by the Master of the High Court. It accepts and holds funds belonging to minors, mentally incapacitated persons, and absent heirs. While it provides a safe repository, it has significant limitations:

Limited growth — the fund earns interest set by the government, which has historically tracked below inflation. A R500,000 inheritance held for 15 years in the Guardian's Fund may have less purchasing power when the child accesses it at 18 than when it was deposited.

Administrative friction — the guardian must apply to the Master's Office for every withdrawal, providing documentation that the funds are needed for the child's maintenance, education, or medical care. Processing times are slow, and applications are sometimes rejected for insufficient documentation.

No investment discretion — the fund cannot invest in equities, property, or other growth assets. A testamentary trust, by contrast, can invest in a diversified portfolio managed by professional fund managers.

Nominating a Guardian in the Will

A testamentary trust protects the money. A guardian nomination protects the child. These are separate appointments — the guardian raises the child, while the trustees manage the inheritance.

Your will can nominate a legal guardian for your minor children. While this nomination is not automatically binding, it carries significant weight. Courts will generally respect a parent's expressed wishes unless there is a compelling reason not to.

Choose the guardian based on who will provide the best day-to-day care for the child — values, parenting approach, geographic stability, and willingness to take on the role. Choose the trustees based on financial competence, integrity, and independence. These should ideally be different people — the guardian should not have unsupervised access to the inheritance.

Tax Implications

Testamentary trusts are taxed as separate entities. Income earned by the trust is taxed at the trust rate (45% for retained income), but income distributed to beneficiaries is taxed in the beneficiary's hands — and minor children have their own tax-free thresholds.

Careful structuring by a tax practitioner can ensure that income is distributed efficiently, minimising the tax burden while maintaining the trust's capital for long-term growth.

Capital gains tax also applies when trust assets are sold. The annual CGT exclusion for trusts is significantly lower than for individuals, so large asset sales should be timed carefully.

Practical Considerations

Name at least two trustees — if one dies, resigns, or becomes incapacitated, the trust can continue to operate without needing a court application to appoint a replacement.

Include a substitution clause — specify who becomes the beneficiary if a child predeceases you or dies before the trust terminates.

Define "maintenance" broadly — include education (school fees, university, tutoring), medical and dental care, housing, clothing, extracurricular activities, and travel. Narrow definitions create disputes between the guardian and trustees about what qualifies as a trust expense.

Set realistic distribution ages — many parents instinctively choose 18, but a lump sum paid to an 18-year-old is frequently squandered. A staggered distribution (one-third at 21, one-third at 25, the remainder at 30) reduces this risk.

Frequently Asked Questions

Can I set up a testamentary trust without an attorney?

Technically yes — any valid will can include trust provisions. But trust clauses are technically complex, and a poorly drafted clause can create tax inefficiencies, administrative difficulties, or ambiguities that lead to costly disputes. The cost of professional drafting (R3,000 to R8,000) is trivial compared to the inheritance it protects.

What happens to the trust if my children are adults when I die?

A testamentary trust for minor children only operates while the beneficiaries are minors (or until the distribution ages you specified). If your children are already adults at the time of your death, the trust clause has no effect — the inheritance passes to them directly under the will.

Can the guardian access trust funds for the child's daily expenses?

The guardian must apply to the trustees, who have discretion to approve or deny the request based on the trust deed's provisions. This separation of control is deliberate — it prevents the guardian from using the child's inheritance for personal expenses while ensuring legitimate needs are met.
