Understanding the Duties of a Curator Bonis in South Africa

A curator bonis is appointed by the High Court under either the Mental Health Care Act 17 of 2002 (for mental incapacity) or the common law (for other incapacity) to administer the property and financial affairs of a person who cannot do so themselves, and once appointed the curator operates under the ongoing supervision of the Master of the High Court. The duties attach from the date of appointment: lodge security with the Master, prepare a sworn inventory of the estate within three months, and thereafter file annual accounts covering income, expenditure, and assets under administration. The curator must act prudently and for the benefit of the patient or person under administration, may not deal with the estate for personal benefit without express authority, and remains in office until the Master’s office discharges the appointment on recovery, death, or a court order terminating the curatorship.

What a Curator Bonis Is — and What a Curator Bonis Is Not

A curator bonis is a court-appointed fiduciary who manages the property and financial affairs of a living person who lacks the capacity to do so themselves. The role is protective and supervisory in nature: the curator steps into the property-management shoes of someone who cannot, for the time being, look after their own financial life, and does so under the watching eye of the Master of the High Court.

The curator bonis role is distinct from, and often confused with, several adjacent fiduciary roles in South African law:

• A curator bonis is not an executor — executors administer deceased estates once someone has died.
• A curator bonis is not a tutor — tutors look after the person (and sometimes property) of a minor, not the finances of an incapacitated adult.
• A curator bonis is not a curator ad litem — a curator ad litem is a litigation representative appointed only for the duration of a specific court case, not an ongoing administrator.
• A curator bonis is not a trustee — trustees administer a trust fund for named beneficiaries under a trust deed, not the estate of a living person who lacks capacity.

The distinction matters because each of those roles is governed by different statutes, supervised by different authorities, and carries a different set of duties. Conflating them is one of the most common reasons curator bonis applications run into procedural difficulties before the Master.

When a Curator Bonis Is Needed

A curator bonis appointment is needed when a living person is unable to manage their own financial affairs, and that incapacity is significant and ongoing enough that an interested party (usually a family member) is willing to bring a formal application to the High Court.

The two principal pathways are:

• Mental illness or severe intellectual disability. Where the person has been positively diagnosed as mentally ill, or has a severe or profound intellectual disability, the Mental Health Care Act 17 of 2002 sets out a statutory pathway. Under this Act the Master of the High Court appoints an “administrator” of the person’s property; the role is the same in substance as a common-law curator bonis, although the statute uses the modern term “administrator.”
• Other incapacity short of mental illness. Conditions such as advanced dementia, severe physical incapacity, or other impairments that prevent a person from acting rationally about their property fall under the common-law route. The High Court appoints the curator under Rule 57 of the Uniform Rules of Court.

Where the underlying incapacity arose through injury, the appointment may sit alongside or follow a personal-injury or motor-vehicle accident (MVA) claims process; where family dispute has prompted the application, family-law practitioners are often the ones bringing the application.

How a Curator Bonis Is Appointed

The pathway to a curator bonis appointment follows a structured sequence, with the exact route depending on whether the matter is brought under the Mental Health Care Act or at common law.

Common-Law Route (Uniform Rule 57)

1. An interested party (typically a family member, but also the Master, a social worker, or an attorney) brings an application to the High Court having jurisdiction over the person whose affairs are to be administered.
2. The application is supported by medical or psychiatric reports and affidavits explaining why a curator is needed, together with identification of the proposed curator.
3. The Master of the High Court is cited as a respondent and files a report on the suitability of the proposed curator and the size of the estate.
4. Where practicable, the person whose affairs are to be administered is given notice and an opportunity to be heard; the court may appoint a curator ad litem to represent that person’s interests during the application itself.
5. The High Court makes the appointment order, which sets out the curator’s powers and the security that must be lodged.
6. The appointed curator lodges security with the Master (cash, a bond, or an insurance guarantee), takes the oath of office, and is then authorised to act.

Mental Health Care Act Route

For persons diagnosed with mental illness or severe or profound intellectual disability, the Mental Health Care Act 17 of 2002 provides a more streamlined route: an interested party lodges an application with the Master of the High Court (Form J197), supported by the relevant medical reports. The Master assesses suitability and the size of the estate, sets the security, and issues letters of appointment. The Master can terminate the administration under section 64 of the Act once the person has recovered sufficiently. The High Court’s involvement in this route is narrower than under the common-law pathway, but the ongoing supervisory obligations on the administrator are the same in substance.

Gauteng Applications — Pretoria and Johannesburg Seats

For Gauteng residents, curator bonis applications are brought in the Gauteng Division of the High Court, which sits in both Pretoria and Johannesburg. Applicants based in Tshwane, Centurion, and the northern reaches of Gauteng typically file at the Pretoria seat; applicants based in Johannesburg, the East and West Rand, and Sedibeng typically file at the Johannesburg seat. The Master of the High Court’s office in the relevant division (Pretoria or Johannesburg) is cited as a respondent, and the Master’s report on the suitability of the proposed curator and the size of the estate determines, among other things, the amount of security the curator will have to lodge. Practitioners handling curator bonis work from Pretoria or Centurion therefore anchor the application at the Pretoria seat of the Gauteng Division, while Johannesburg- and East-Rand-based practitioners anchor at the Johannesburg seat. Once appointed, the curator files the three-month inventory, the annual accounts, and any ad hoc applications for authority (such as a sale of immovable property) with the same Master’s office in the division of appointment.

The Core Duties of a Curator Bonis Once Appointed

Once the appointment is made and the curator has lodged security and taken the oath of office, a defined set of statutory and common-law duties attaches. The duties are not optional — they are what the Master’s office scrutinises on an ongoing basis, and failure to perform them can lead to suspension or discharge of the appointment.

Lodge Security with the Master

Before acting, the curator must lodge security sufficient to cover the value of the estate under administration (Form J262, the “Bond of Security”). The security is released only on proper discharge of the curatorship, and is in substance the Master’s guarantee that any loss caused by the curator’s mismanagement can be made good out of the security.

Take the Oath of Office

The curator formally accepts the appointment and the fiduciary duties that attach to it. The oath is what gives the curator authority to act in the name of the person under administration.

Prepare and File a Sworn Inventory

Within three months of appointment, the curator must prepare and file a sworn inventory (Form J243) of the assets and liabilities of the person under administration. The inventory is lodged with the Master and forms the baseline against which the curator’s annual accounts are later measured.

Administer the Estate Prudently

The curator collects income, pays debts and outgoings, keeps proper records, and acts at all times in the best interests of the person under administration. The Master scrutinises the administration on an ongoing basis and may require corrections.

File Annual Accounts

The curator must lodge a yearly administration account with the Master, detailing income, expenses, and capital asset values, supported by vouchers and reconciliations. This is the Master’s primary supervisory tool — it is what allows the Master’s office to audit the administration on an ongoing basis.

Apply to the Master for Authority Before Non-Routine Transactions

Selling immovable property, instituting or defending litigation, making major investments, or changing the structure of the estate are non-routine transactions that the curator may not undertake on the curator’s own authority. The curator must apply to the Master (or to the court) for prior written authority before doing so.

Avoid Self-Dealing and Conflict-of-Interest Transactions

The curator may not benefit personally from the administration except where the court or the Master’s express authority allows it. The fiduciary duties that attach to the curatorship are similar to those that apply to an executor or a trustee.

Support the Person Under Administration

The curator must use the income and capital of the estate as the person’s needs reasonably require, supporting the person (and any dependants) from the estate under administration.

Report Material Changes to the Master

The curator must report to the Master’s office on any change in the condition of the person under administration that might warrant a variation or termination of the curatorship — most notably, recovery, which triggers the termination process.

Comparing the Curator Bonis with Adjacent Roles

The table below sets out the key differences between a curator bonis and the most commonly confused adjacent fiduciary roles in South African law.

Role	Appointed by	Purpose	Duration	Typical trigger
Curator bonis (or “administrator” under the Mental Health Care Act)	High Court (common law) or Master (Mental Health Care Act)	Administer the property and finances of a living person unable to manage their own affairs	Indefinite (until recovery, death, or termination by court)	Mental illness, intellectual disability, dementia, severe incapacity
Curator ad litem	High Court (or court before whom proceedings are pending)	Represent a person’s interests in specific litigation because they cannot do so themselves	Limited to the litigation in question	Minor or unborn or unascertained beneficiary in court proceedings; person under disability defending or bringing a claim
Tutor	High Court (and the Master for minors)	Look after the person (and sometimes property) of a minor	Until the minor reaches majority	Minor child whose parents are deceased, unfit, or absent
Executor	Master of the High Court (under a will) or the court (intestate)	Administer a deceased estate	Until the estate is wound up and final accounts are filed	Death of the deceased
Trustee	Trust deed (or court if the deed is silent or defective)	Administer a trust fund for named beneficiaries	Indefinite (per the trust deed)	Creation of an inter vivos trust or a testamentary trust in a will

The point that most often trips families up is that the curator bonis, the curator ad litem, and the tutor are all appointed by the High Court, but they do completely different things. Where a practitioner or family member is uncertain which of these roles is needed, the starting question is always: what problem are we actually solving — managing someone’s finances because they cannot, representing someone in a court case because they cannot, or caring for a minor’s person because no one else can?

How the Duties End

The curatorship is not indefinite by default — it ends on one of several defined triggers, after which the curator must wrap up the administration and apply to be released.

• Death of the person under administration. The curator’s role ends on death, after which an executor is appointed for the deceased estate.
• Recovery of the person under administration. The court (under Rule 57) or the Master (under section 64 of the Mental Health Care Act) may discharge the appointment on application supported by medical evidence of recovery.
• Termination on the curator’s own application. The court may terminate the curatorship where the curator applies to be discharged.
• Termination by the court on Master’s report. Where the Master’s office reports that the curator is no longer suitable or has failed to perform the duties, the court may suspend or discharge the appointment.

On termination, the curator must lodge final accounts with the Master and apply for release from the security lodged at appointment. Until the curator is formally released, the curator remains answerable to the Master for any shortfall — the lodged security stays in place until the Master’s office is satisfied that the administration has been properly wound up.

What Happens If a Curator Bonis Fails to Perform the Duties

The Master’s office has a graduated set of responses available where a curator fails to perform the duties, ranging from informal correction to formal removal and personal liability.

• The Master’s office can call for an explanation, audit the annual accounts, and require corrections.
• The Master can report the curator to the court, which may suspend or discharge the appointment and direct the curator to make good any loss.
• Beneficiaries (typically the person under administration, or dependants supported from the estate) may bring a claim against the curator personally for breach of fiduciary duty.
• The curator’s lodged security is available to satisfy any liability the Master or court finds against the curator before the curator is released.

The security lodged at appointment is what makes the supervisory regime workable in practice — it is the Master’s enforcement tool, and it is also the practical assurance for the person under administration that the estate is protected against mismanagement even before any claim is proved.

Where This Work Crosses the Firm’s Other Practice Areas

Curator bonis work sits inside the broader fiduciary-administration track that a wills-and-estates practice already covers, and it regularly intersects with the firm’s other practice areas.

• A curator bonis for a person who is also a beneficiary under a will may need to coordinate with the executor appointed under that will after the person’s death.
• A curator bonis for a beneficiary of a trust needs to interact with the trustees on income and capital distributions.
• Where the underlying incapacity arose through injury, the appointment may sit alongside or follow a personal-injury or motor-vehicle accident claims process.
• Where family dispute has prompted the application, family-law practitioners are often the ones bringing the application.

For a family dealing with all of this at once — a parent losing capacity, a will already in place, a trust set up years ago, and an injury claim still running — the value of having a single firm that can handle the curator appointment, the will, the trust interaction, and the underlying litigation is that the curator’s duties (annual accounts, Master’s reporting, applications for authority) can be coordinated rather than handed off between unrelated advisers. Burger Huyser Attorneys’ Wills & Estates practice covers this scope, with the Pretoria and Centurion branches anchored to the Pretoria seat of the Gauteng Division for curator bonis applications.

Frequently Asked Questions

Who can apply to be appointed as curator bonis?

Any suitable adult may be proposed — typically a family member, a close friend, or a professional such as an attorney, accountant, or trust company. The Master of the High Court assesses suitability in its report to the court, and the court has the final say. Unsuitability (for example, an undischarged insolvent, a person with a criminal record involving dishonesty, or a person with a conflict of interest) can disqualify a candidate.

Does the person whose affairs will be administered get a say?

Where practicable, yes. The court requires notice to be given to the person whose affairs are to be administered, and that person is entitled to oppose the application or to propose an alternative curator. In mental-health matters under the Mental Health Care Act, a curator ad litem is typically appointed to represent the person’s interests during the application.

How much does a curator bonis get paid?

The curator’s remuneration is set by the Master’s office (or by the court on application), and is ordinarily calculated as a percentage of the gross income and capital of the estate under administration, subject to a tariff. Under the Administration of Estates Act the standard tariff is 6% on annual income and 2% on capital asset value at termination. Where the curator is a professional such as an attorney or accountant, professional fees may be claimed; the Master must approve the tariff before it is charged, and may reduce, disallow, or increase the fees for special reasons.

What is the difference between a curator bonis and an executor?

A curator bonis administers the affairs of a living person who cannot do so themselves; an executor administers a deceased estate after death. The two roles sometimes interact — for example, where a person under curatorship dies, the curator’s role ends and an executor (appointed either under the deceased’s will or by the Master for an intestate estate) takes over.

Can a curator bonis sell the person’s house?

Not without authority. Selling immovable property is a non-routine transaction that requires either the Master’s prior written authority or a court order. The Master will typically authorise a sale only on evidence that it is in the best interests of the person under administration — for example, to fund care, to remove a property that is unsafe, or to release tied-up capital.

How long does a curatorship last?

Until the court discharges the appointment. This usually happens on the death of the person under administration, on recovery supported by medical evidence, or on the court accepting the curator’s application to be discharged. There is no fixed term — the curatorship endures for as long as the incapacity does.
