What is the Most Important Decision in Estate Planning?

The single most consequential decision in South African estate planning is whether you have a valid, current will. Every other estate planning choice — executor appointment, guardian nomination for minor children, trust structuring, liquidity provision, beneficiary identification — flows from that will or fails in its absence. Under the Administration of Estates Act 66 of 1965, dying without a valid will triggers a default inheritance regime the deceased may not have wanted, and the Master of the High Court — not the family — appoints an administrator to wind up the estate. Drafting the will is not the only estate planning decision, but it is the foundational one: it sets the framework inside which every other decision becomes meaningful, or, in its absence, irrelevant.

Why “the Will” Beats the Other Decisions in Importance

A valid will is the document that activates every other estate planning tool. Through a will the testator can nominate an executor, name a guardian for minor children, set up a testamentary trust, identify specific bequests and residuary heirs, and direct how business interests, retirement funds, and policy proceeds are to be handled through the estate. Without a valid will, none of those choices can be exercised.

Where there is no valid will, the Intestate Succession Act 81 of 1987 applies, the Master of the High Court appoints an administrator (often a family member, sometimes a stranger), and the default inheritance rules may distribute the estate in ways the deceased would not have chosen. All other estate planning decisions — executor selection, trust formation, liquidity planning, tax structuring — operate inside the will. If the will is absent, those decisions have no vehicle to ride on, and the legislature’s default rules take over.

What the Wills Act 7 of 1953 Actually Requires

For a will to be valid in South Africa, the formalities set out in the Wills Act must be satisfied. A defective will can be challenged or set aside, which is why executors and the Master pay close attention to compliance at the reporting stage.

Requirement	What the Wills Act 7 of 1953 says
Age of the testator	The testator must be at least 16 years old, or, if married or previously married, the age of majority.
Form	The will must be in writing.
Witnesses	Signed by the testator in the presence of two or more competent witnesses, who simultaneously attest and sign the will in the testator’s presence and in the presence of each other.
Testamentary capacity	The testator must understand the nature of making a will, the extent of the estate, the claims of those who might expect to inherit, and must not be suffering from a disorder of the mind that influences the disposition.
Signature	The testator must sign at the end of the will. Any matter after the signature is generally ignored, and adding pages or amendments after execution usually requires a formal codicil or a new will.

A common practical pitfall is the “beneficiary as witness” problem: a witness (or the spouse of a witness) who is also a beneficiary under the will generally forfeits the benefit, even though the will itself remains valid. Using independent witnesses avoids this trap.

The Decision Tree: Have a Will, Update It, or Draft One Now

Once “have a will” is accepted as the most important decision, the next question is which branch of the decision tree applies to the reader.

• No will exists. The highest-leverage decision is to draft one now, however simple the estate looks. The cost of drafting a basic will is a fraction of the cost of intestate administration, and far less than the family friction that often follows it.
• Will exists but is years out of date. Marriage, divorce, the birth of a child, the death of an heir, a change in property ownership, or a change in business interests all break the assumptions the original will was drafted on. Section 2B of the Wills Act now provides a limited safety net for some unintentional revocations on divorce, but marriage still revokes a prior will unless the will is clearly expressed to be made in contemplation of that marriage.
• Will exists and is current. The decision shifts to making sure the executors nominated are still alive and willing, the chosen guardians are still appropriate, and the liquidity (cash, policies, access to retirement proceeds) is sufficient to settle the estate without forcing a sale of family assets.

Why Choosing an Executor Is the Strong Runner-Up

The executor (or executors) named in the will is the person or institution that winds up the estate after death — collects assets, pays debts, lodges the liquidation and distribution account with the Master, and distributes to heirs. The Master is not bound to confirm the testator’s nominated executor; it may decline if the nominated party is unsuitable, incapacitated, or unwilling, in which case it appoints another. But having a willing, capable, named executor shortens the process dramatically.

A specialist fiduciary firm — or a co-executor pairing of a family member and an attorney — reduces the risk of conflict, family disputes, and amateur errors in the administration account, which can stall the Master’s approval for months. Burger Huyser Attorneys handles deceased estate administration across Gauteng and can be nominated as executor or co-executor from any branch.

The Other Important Decisions That Rank Behind the Will

These decisions all matter, but each one only works if the will itself is in place.

Decision	Why it ranks behind the will
Liquidity planning	Ensures the estate has enough cash to cover debts, taxes (where applicable), and administration costs without a forced sale of the family home or business. Retirement funds and life policies with nominated beneficiaries bypass the estate and are paid directly, but only if the nominations are current.
Trust formation	Inter vivos (living) trusts and testamentary trusts have legitimate roles but are situational tools; without a will, a testamentary trust cannot be created at all.
Beneficiary nominations on retirement funds and policies	These override the will for the asset in question, which means an outdated nomination can defeat the entire estate plan. Review nominations at the same life events as the will itself.
Power of attorney and advance directives	Relevant during life rather than after death, but a properly drafted general power of attorney and a living will (advance healthcare directive) protect the testator’s autonomy if they become incapacitated before the estate plan is triggered.

What Happens When the Most Important Decision Is Skipped: Intestate Succession

The Intestate Succession Act 81 of 1987 sets the default distribution order — surviving spouse, descendants, parents, siblings, and more distant relatives in a defined sequence, with the spouse’s share depending on whether there are descendants and whether the marriage was in or out of community of property. A customary marriage, a civil union, or a Muslim marriage recognised under the Recognition of Customary Marriages Act and the Civil Union Act each carry specific intestate consequences — none of which the deceased gets to shape if there is no will.

The Master’s appointment of an administrator can be contested, the heirs’ identities may need to be proven genealogically (slowing the process), and the family home or business may have to be sold to settle the estate if the heirs cannot agree on a way forward. The process is typically slower and more expensive than testate administration, and the heirs may not receive what the deceased would have wanted.

Practical Considerations: When, How, and What to Bring

Wills should be reviewed at every major life event — marriage, divorce, birth, death, acquisition or disposal of a major asset, starting or selling a business — and at least every three to five years regardless of life events. The first consultation for a basic will typically requires:

1. ID document for the testator (and usually for the spouse, if relevant).
2. A list of assets and liabilities — immovable property, vehicles, policies, retirement fund interests, business interests, debts.
3. The full names and details of intended heirs and any specific bequests.
4. The names of intended executors and, where there are minor children, intended guardians.

Original wills should be kept in safe custody — most attorneys keep the original in their deed’s safe and the client retains a copy; the Master does not hold original wills. Burger Huyser Attorneys’ Wills & Estates practice drafts standard wills, complex wills with testamentary trusts, and cohabitation / antenuptial planning across Gauteng from the Linden/Randburg head office.

Frequently Asked Questions

What is the single most important decision in estate planning in South Africa?

Whether you have a valid, current will. Every other estate planning decision — executor nomination, guardian appointment, trust structuring, beneficiary identification, liquidity planning — flows from the will or fails in its absence. Without a valid will, the Administration of Estates Act 66 of 1965 and the Intestate Succession Act 81 of 1987 dictate what happens, and the Master of the High Court (not the family) appoints an administrator to wind up the estate.

What makes a will legally valid in South Africa?

Under the Wills Act 7 of 1953, the testator must be at least 16 (or the age of majority if married or previously married), the will must be in writing, signed by the testator at the end in the presence of two or more competent witnesses who simultaneously attest and sign in the testator’s presence and in the presence of each other, and the testator must have testamentary capacity at the time of signing.

Does getting married or divorced cancel my old will?

Marriage generally revokes a prior will unless the will is clearly expressed to have been made in contemplation of that marriage, and divorce used to revoke benefits to a former spouse until section 2B of the Wills Act introduced a limited safety net. Both events are triggers to draft a fresh will or a formal codicil — relying on an outdated will after a major change in marital status is one of the most common and avoidable estate planning mistakes.

What happens if I die without a will in South Africa?

The Intestate Succession Act 81 of 1987 sets a default distribution order based on the surviving spouse, descendants, parents, and more distant relatives in a defined sequence. The Master of the High Court appoints an administrator (often a family member, sometimes a third party) to wind up the estate, and the heirs may not receive what the deceased would have wanted. The process is typically slower and more expensive than testate administration.

Can I nominate an attorney as executor of my will?

Yes. The testator may nominate an individual or an institution as executor (or co-executor alongside a family member), and the Master will normally confirm the nomination unless the party is unsuitable, incapacitated, or unwilling. A specialist firm like Burger Huyser Attorneys can be nominated to act alone or in partnership with a family member, which reduces the risk of amateur errors in the Master’s liquidation and distribution account and protects the estate against family conflict.
