Testamentary Trust vs Will: Understanding the Difference

A will is a document that takes legal effect only on the testator’s death, instructing the Executor on how to distribute the deceased’s estate under the Wills Act 7 of 1953. A testamentary trust is not a separate instrument — it is a trust created by a clause inside the will, which comes into existence on the testator’s death and holds and manages assets on behalf of specified beneficiaries under the Trust Property Control Act 57 of 1988. The two are not alternatives: every testamentary trust is set up through a will, and the choice a testator actually faces is whether to leave assets outright in the will or to ring-fence them in a trust created by the will.

What a Will Does (and What It Cannot Do)

A will takes legal effect only on the testator’s death and is administered by the Executor named in the will — or, where no Executor is named or able to act, by an Executor appointed by the Master of the High Court. Under the Wills Act, the will directs who inherits, what they inherit, and on what terms. Once the Executor files the liquidation and distribution account and that account is approved by the Master, the assets vest absolutely in the named beneficiaries.

A bare will cannot keep assets under ongoing management after distribution. Where a minor child inherits in their own name, the inheritance technically vests in the child on reaching majority at age 18, and any management in the intervening period depends on a separate guardianship arrangement layered on top. A will also cannot impose ongoing conditions on how a beneficiary uses an inheritance once it has vested — attempts to do so can be challenged, and the Western Cape High Court’s decision in Hanekom v Voight N.O and Others 2016 (1) SA 416 (WCC) is widely treated by practitioners as the leading authority on the boundary between permissible testamentary conditions and impermissible attempts to fetter a beneficiary’s ownership.

What a Testamentary Trust Adds on Top of a Will

A testamentary trust is created by a clause inside the will — naming trustees, beneficiaries, and the terms on which trust assets are held and distributed. It has no legal existence before the testator dies. On the testator’s death, the inheritance that would otherwise have vested in a beneficiary outright is instead held by the trustees in terms of the trust deed (which is itself part of the will), and is administered for the beneficiary’s benefit until the trust terminates.

The trust must be registered with the Master of the High Court, and the Master issues letters of authority to the trustees — without those letters, the trustees cannot open a trust bank account, invest trust funds, or make distributions. A common misconception is that “you need a trust as well as a will.” That is wrong: a properly drafted will can contain the full trust establishment clause, and that single instrument does both jobs.

Burger Huyser Attorneys’ Wills & Estates team at the Linden, Randburg head office drafts both straightforward wills and wills containing testamentary trust clauses, and works through the trade-offs in a single consultation.

Side-by-Side Comparison: Will vs Testamentary Trust

Dimension	Will (only)	Testamentary Trust (inside the will)
When it takes effect	On the testator’s death	On the testator’s death (no existence during the testator’s lifetime)
Who manages the inheritance	Executor until the liquidation and distribution account is approved; thereafter the beneficiary	Trustees, for the duration of the trust
Vesting of ownership	Vests absolutely in the named beneficiary once the estate is finalised	Held by the trustees; beneficiary has a right to benefit, not direct ownership of the underlying assets
Position of a minor beneficiary	Inherits in their own name at age 18 — a guardian or parent must manage the money in the meantime	Trust holds the inheritance until the age specified in the trust deed (often a staged distribution at 18, 21, 25)
Ongoing administration after death	None (Executor’s role ends when the estate is wound up)	Annual accounting to the Master; trustees continue managing the trust until it terminates
Cost to set up	Standard will-drafting fee	Will-drafting fee plus a more involved trust clause (longer drafting time, more consultations)
Cost after death	Executor remuneration and Master’s Office fees	Executor and Master’s fees plus ongoing trust-administration fees, trustee fees, annual accounting
Tax treatment of income	Income tax in the beneficiary’s hands once distributed	Trust itself is taxed (currently at a flat 45% on trust income, less any exemption); distributions to beneficiaries can be tax-neutral if structured correctly
Termination	Distribution of the estate closes the file	Trust terminates on the date or event specified in the trust deed (commonly the beneficiary reaching a stated age, or the death of the last beneficiary)
Best suited to	Simple estates with adult beneficiaries who can manage their own inheritance	Estates with minor children, vulnerable or financially inexperienced beneficiaries, blended-family situations, or assets that should not vest outright

When a Plain Will Is Enough

• The beneficiaries are all adults with no need for ongoing management of their inheritance.
• The estate is straightforward — no blended-family complications, no business interests that need protection, and no concern about a beneficiary’s creditors.
• The testator does not want the additional cost and ongoing administration burden of a trust.

For these estates, a will that nominates an Executor, sets out bequests, and provides a residuary clause is generally sufficient. This is the position most adult-only testators with simple estates end up in, and it is where most of Burger Huyser Attorneys’ standard will-drafting work sits.

When a Testamentary Trust Should Be Built Into the Will

• There are minor children (under 18) who stand to inherit — without a trust, the inheritance vests in them at majority with no staged hand-over and no protection in between.
• A beneficiary has a disability, addiction, or financial-management difficulty that makes outright vesting risky.
• The testator wants to protect an inheritance from the beneficiary’s creditors or from a future marriage (the trust assets do not form part of a beneficiary’s personal estate).
• The testator wants staged distributions — for example, one-third at 21, one-third at 25, balance at 30 — rather than a lump-sum inheritance on the day the beneficiary turns 18.
• The estate includes a family business or other asset that should not be sold or divided on the testator’s death, but should continue to be managed for the family’s benefit.

How the Two Are Set Up Together in Practice

In practice, the will is drafted first and includes the standard Executor appointment, the bequests, and the residuary clause. Inside the will, a separate clause sets up the testamentary trust, names the trustees (typically with a substitute if a named trustee predeceases the testator or is unable to act), names the beneficiaries, and sets out the trust’s vesting date or distribution milestones.

After the testator’s death, the trustees apply to the Master of the High Court for letters of authority once the estate has been reported; until those letters issue, the trustees cannot open a trust bank account, invest trust funds, or make distributions. The trustees then administer the trust under the will and the Trust Property Control Act, with annual accounting and reporting obligations to the Master for the duration of the trust.

1. Will drafted with Executor appointment, bequests, residuary clause, and trust clause.
2. Testator dies; Executor reports the estate to the Master of the High Court.
3. Trustees apply for letters of authority once the estate’s liquidation and distribution account has been reported.
4. Trustees open a trust bank account, invest trust funds, and make distributions in line with the trust deed.
5. Trustees submit annual accounting to the Master until the trust terminates.

What It Costs and What the Ongoing Obligations Look Like

Drafting a will with a testamentary trust clause costs more than a straightforward will because the trust provisions, trustee nominations, and vesting provisions require additional drafting time and a more detailed consultation. After the testator’s death, the estate still has to be wound up by the Executor; the trust then adds a parallel layer of administration — a trust bank account, annual accounting, and Master’s Office compliance — that continues until the trust terminates.

Trustees carry fiduciary duties under the Trust Property Control Act and can be held personally liable for breach, so choosing competent trustees and accepting the ongoing compliance burden is part of the decision. Fees are quoted per file after the first review; Burger Huyser Attorneys does not publish fixed fees for trust-clause drafting because the scope depends on the number of beneficiaries, the vesting schedule, and the trustee structure.

Practical Drafting Pointers

• Nominate at least one trustee (typically two, with a substitute) and provide for the contingency of a trustee predeceasing the testator or being unable to act.
• Set out the beneficiaries, the vesting age, the trustees’ powers (investment, distribution, capital vs income), and the trust’s termination event in the trust clause inside the will.
• Nominate trustees in the will rather than leaving the appointment to the Master’s default rules — the Master has discretion where the will is silent, and that discretion does not always produce the result the testator would have wanted.
• Review the will and trust clause every few years, particularly after life events (birth of a new grandchild, divorce, change in financial circumstances). The trust can be amended by codicil, but a full will revision is usually simpler.

Supervision by the Master’s Office and Filing Through the Johannesburg or Pretoria Seat

Every deceased estate in South Africa is administered under the supervision of the Master of the High Court, and the Master’s Office that serves a particular estate depends on where the deceased was ordinarily resident at death. For Gauteng testators, estates are reported either to the Master’s Office in Johannesburg (covering the southern and central Magisterial Districts — Johannesburg, Randburg, Sandton, Roodepoort, Bedfordview, Alberton, and Midrand) or to the Master’s Office in Pretoria (covering the northern districts, including Pretoria, Centurion, and Menlyn).

The same regional split applies to the registration of a testamentary trust once activated by the testator’s death: the trust is registered with the same Master’s Office that handles the deceased estate. The Master will only issue letters of authority once the underlying estate’s liquidation and distribution account has been reported and the trust assets have vested in the trustees — which is why the trust’s administration is sequenced behind the estate’s winding-up, not run in parallel from day one.

For Randburg, Johannesburg, Sandton, Roodepoort, Bedfordview, Alberton, and Midrand estates, the relevant Master’s Office is Johannesburg. For Pretoria, Centurion, and Menlyn estates, it is Pretoria. The Master of the High Court’s portal on justice.gov.za, and the Department’s “How to report a deceased estate” page, are the authoritative sources for current filing fees, reporting forms, and any updates to the deceased-estate-administration timelines.

Burger Huyser Attorneys’ head office at 49 First Avenue, Linden, Randburg handles wills, testamentary trust drafting, and deceased estate administration for the Johannesburg-seat Magisterial Districts. For clients based in the northern districts (Pretoria, Centurion, Menlyn), the firm’s Pretoria branch at Unit 4, 1st Floor, Block 5, Glen Manor Office Park, 138 Frikkie De Beer Street, Menlyn (012 471 5700) is the practical intake point and reports estates into the Pretoria Master’s Office. The same firm — under one Deceased Estate Administrator (Lance Pearson) — administers the resulting testamentary trust alongside the underlying estate.

Frequently Asked Questions

Do I need a separate trust deed if I want a testamentary trust?

No. A testamentary trust is created by a clause inside the will itself, not by a separate trust deed signed during the testator’s lifetime. The trust has no legal existence until the testator dies, and the terms of the trust are set out in the will. A separate trust deed is only needed for an inter vivos (living) trust, which is a different instrument.

At what age can a child inherit under a South African will?

Under South African law, a minor (anyone under 18) can inherit, but cannot give a valid receipt for the inheritance until they reach majority or have a legal guardian appointed to receive it on their behalf. Without a testamentary trust, the inheritance technically vests in the minor and a guardian has to manage the funds until the child turns 18, at which point the full amount is handed over with no staged release.

Does a testamentary trust avoid estate duty?

No. Assets that flow into a testamentary trust on the testator’s death are still included in the deceased estate for estate duty purposes under the Estate Duty Act 45 of 1955. The trust does not by itself reduce estate duty, although proper structuring (bequests to a surviving spouse, the section 4(q) deduction, and other statutory exemptions) can reduce the dutiable amount. The trust’s main advantage is what happens after estate duty has been assessed, not avoiding the duty itself.

Can I update my testamentary trust after the will has been signed?

Yes. The trust clause is part of the will, so amending the trust clause means amending the will by way of a codicil or a new will. Lifetime changes to the testator’s circumstances (a new grandchild, a divorce, a change in financial position) usually warrant a full will revision rather than a series of small codicils.

Who can be the trustee of my testamentary trust?

Any natural person — or in some cases a corporate trustee such as a trust company or a bank’s fiduciary division — who is willing to act and whom the Master of the High Court will accept as fit and proper. Most testators nominate a spouse, an adult child, a sibling, or a professional advisor. A substitute trustee should always be named in case the first choice predeceases the testator or is unable to act.

What happens if a beneficiary dies before the testator?

The will’s accrual clause (the default rule under the Wills Act 7 of 1953) determines whether that beneficiary’s share lapses, accrues to the other beneficiaries, or falls into the residue. A properly drafted will specifies what happens in this scenario — without it, the default accrual rule applies and can produce unintended consequences.
