The Power of Attorney Myth: Planning for Incapacity in South Africa

Many families believe they have planned for a parent's old age because a power of attorney has been signed. It is one of the most dangerous misconceptions in South African law. A power of attorney fails at precisely the moment it is needed most: the moment the person who granted it loses the mental capacity to manage their own affairs. Understanding why — and what the law offers instead — is essential for anyone caring for an ageing parent or planning their own later years.

What a power of attorney actually is

A power of attorney is an instrument of agency. The principal (the person granting the power) authorises an agent to act on their behalf — either for a specific task, such as signing transfer documents (a special power of attorney), or for their affairs generally (a general power of attorney). Two points follow from that legal nature. First, the principal does not give up any power: they can still act for themselves, and can revoke the authority at any time. Second, and critically, the agent can never have greater capacity to act than the principal. The agent is merely the principal's hand; the mind must remain the principal's.

The critical flaw: it lapses on incapacity

Because an agent only extends the principal's own legal capacity, a power of attorney automatically lapses when the principal loses the mental capacity to make decisions — for example through dementia, a stroke or a serious brain injury. From that moment, anything the agent does under the lapsed power is invalid, even if the family, the bank and the agent all act in perfect good faith. An agent who continues to sign, transact and withdraw on a lapsed power exposes themselves to personal liability and the transactions to being unwound.

Unlike the United Kingdom and many other jurisdictions, South African law does not currently recognise an enduring power of attorney — one that survives, or only comes into force upon, the principal's incapacity. Clauses purporting to make a South African power of attorney "enduring" have no effect. The South African Law Reform Commission recommended the introduction of enduring powers of attorney in its Project 122 report on assisted decision-making as far back as December 2015, but that recommendation has not yet been enacted into law. Until it is, families must use the mechanisms that do exist.

Option 1: curatorship through the High Court

The traditional remedy is an application to the High Court, under Rule 57 of the Uniform Rules of Court, to declare a person incapable of managing their own affairs and to appoint a curator. A curator bonis is appointed to manage the person's property and financial affairs; where decisions about the person's body and welfare are needed, a curator personae may be appointed. The application is served on interested parties and supported by medical evidence, and the court appoints an advocate as curator ad litem to investigate and report independently on the person's condition and best interests.

Curatorship offers strong judicial oversight — the curator acts under the supervision of the Master of the High Court, must usually furnish security and must account for their administration. The drawbacks are equally real: the procedure is expensive, slow and public, and it strips the person of control in a way many families find distressing.

Option 2: an administrator under the Mental Health Care Act

A more accessible route exists under the Mental Health Care Act 17 of 2002. Where a person has been diagnosed as mentally ill, or has a severe or profound intellectual disability, an application may be made to the Master of the High Court for the appointment of an administrator to care for and administer that person's property. Because the application is made to the Master rather than by way of High Court proceedings, it is generally quicker and considerably less expensive than curatorship. The administrator, once appointed, controls and administers the person's assets and applies them for the person's maintenance and benefit, subject to the powers and duties set out in the Act.

Which route is appropriate depends on the nature of the incapacity, the size and complexity of the estate, and whether decisions about the person (and not only their property) are required. We advise families on both procedures as part of our estate planning services.

Planning while you still can

The uncomfortable truth is that once capacity is lost, every remaining option involves a formal application and months of delay. The time to plan is while you are still well. Sensible measures include:

• An inter vivos (living) trust. Assets transferred to a family trust are managed by its trustees, and that management continues seamlessly if you later lose capacity. For many clients this is the closest South African law comes to an enduring arrangement.
• A power of attorney for the good years. A general power of attorney remains genuinely useful for convenience while you have capacity — for travel, illness or immobility — provided everyone understands that it will lapse if capacity is lost.
• An up-to-date will. Incapacity planning and estate planning go hand in hand; a will cannot be validly made or changed once capacity is gone.
• Structuring access for your spouse or family — reviewing how accounts, investments and policies are held, so that a household is not paralysed the day one member can no longer transact.
• Recording your wishes. Document where your important papers are kept and discuss your preferences for care and finances with your family and advisers while you can still express them.

Act before the gap, not after it

Incapacity rarely announces itself in advance. Families who assume a power of attorney has them covered often discover the gap only when a bank declines a transaction — and by then, only curatorship or administration can bridge it. If you are planning for your own future, or you are watching a parent's capacity decline, contact us early. The earlier the planning, the more options remain open.
