If You Have Children Under 18, Your Estate Plan Has a Gap. Here Is How to Close It.
Most parents believe that if they die, the people they love will take care of their children and their children’s money. That belief is natural, deeply human, and in many cases legally incorrect. South African law has very specific rules about what happens to minor children and their inheritance when a parent dies, and those rules do not care about your intentions, your verbal agreements, or your assumption that things will be sorted out sensibly by the people you trust. By the end of this article, you will understand exactly what the law does with your children’s inheritance if you have not made specific provision in your will, why that outcome is almost never what parents actually want, and what three structures you can put in place today to make sure your children are genuinely protected, not just technically provided for.
The Assumption Most Parents Make, and Why It Is Wrong
When I ask parents what would happen to their children if both parents died tomorrow, the answer is almost always some version of the same thing. My sister would take them. My parents would step in. We have always said that my brother and his wife would raise them if anything happened to us.
That arrangement, spoken about, agreed to in principle, assumed rather than documented, is not legally binding. It is a conversation. And a conversation cannot protect your children in a courtroom, in a Master’s office, or in any legal proceeding that determines what happens to them and their money after you are gone.
The law does not know about the conversation. It knows about your will. If your will does not name a guardian, if your will does not include a testamentary trust, if your will does not address what happens to your children’s inheritance until they are adults, the law fills those gaps with its own defaults. And those defaults are rarely what any parent would have chosen.
The law does not know about the conversation you had with your sister. It knows about your will.
What the Law Actually Does With Your Children’s Inheritance
Let us start with the money, because this is where most parents are most surprised.
The Guardian’s Fund: The Default Nobody Chooses
If you die and your children are under 18, any cash inheritance they receive from your estate cannot be held by a family member on their behalf. It cannot sit in a bank account managed by your sister or your parents, no matter how trustworthy or capable they are. Under the Administration of Estates Act, a minor cannot legally own or manage assets of significant value. Someone must manage those assets on their behalf.
If your will does not create a trust for that purpose, the money goes to the Guardian’s Fund. The Guardian’s Fund is a government fund administered by the Master of the High Court. It is a legal holding mechanism, not a wealth management vehicle. Here is what that means in practice.
Your children cannot access the funds until they turn 18
No matter how young they are when you die, no matter what financial needs arise during their childhood, the funds are held in the Guardian’s Fund until each child reaches majority. There is no flexibility. A 16-year-old who needs funds for university cannot access them early. A 14-year-old who needs specialised medical care cannot access the funds that were left specifically to provide for them.
They receive everything as a lump sum at 18
When each child turns 18, they receive the full balance of their share in a single payment. There are no conditions attached. No requirement that the money be used for education, housing, or any other specific purpose. An 18-year-old, still in their first year of adulthood, possibly still raw with grief, receives a potentially significant sum of money with no guidance, no structure, and no protection around how it is used.
You have no say over how the money is invested in the meantime
The Guardian’s Fund invests conservatively and collectively. You cannot specify an investment approach. You cannot direct the funds toward growth assets. You cannot ensure the real value of your children’s inheritance is preserved in the way a properly structured trust, managed by trustees of your choosing, could achieve.
Navigating the Guardian’s Fund is administratively burdensome
The guardian who is raising your children, already managing an enormous practical and emotional load, must deal with the Master’s office every time they need to access funds for the children’s reasonable needs. The process involves applications, approvals, and delays that add administrative strain to an already difficult life.
The Guardian’s Fund is what the law provides. A testamentary trust is what parents actually want.
The Three Structures That Actually Protect Your Children
There are three elements of an estate plan that work together to protect minor children comprehensively. Each addresses a different dimension of the risk. Together they form a complete plan.
Structure 1: The Guardian Appointment
A guardian is the person who will raise your children if you die while they are still minors. The appointment of a guardian is made in your will, and it is one of the most important decisions a parent can make.
Without a named guardian in your will, the appointment of a guardian falls to the High Court. The court will consider what is in the best interests of the child, which is the correct legal standard. But it means a legal process, potential delays, and an outcome determined by a court that does not know your children, your family, or your values.
What to consider when choosing a guardian
The choice of guardian is deeply personal and there is no universally correct answer. Here are the questions worth working through deliberately.
- Do they share your values around parenting, education, religion, and lifestyle?
- Are they physically and emotionally capable of raising additional children?
- Do they live in a location that would minimise disruption to your children’s schooling and social environment?
- Do they have a stable relationship and home environment?
- Have you spoken to them directly and confirmed they are willing and prepared to take on this responsibility?
- What happens if your chosen guardian predeceases you or becomes incapable? Have you named a substitute?
The guardian does not need to be the same person as the trustee of your children’s testamentary trust. In fact, there is a strong argument for separating these roles. The guardian focuses on the day-to-day care of your children. The trustee manages the financial assets. The separation of these functions creates a natural check that protects your children’s interests from all angles.
Structure 2: The Testamentary Trust
A testamentary trust is a trust that is created by your will and comes into effect when you die. It does not exist before your death. It is not a structure you set up and manage during your lifetime. It is a set of instructions in your will that tells the executor and the trustees exactly how your children’s inheritance must be managed until the point you specify.
This is the single most powerful tool available to parents for protecting a minor child’s inheritance. Here is what it gives you that the Guardian’s Fund cannot.
You choose the trustees
The trustees of your testamentary trust are the people responsible for managing the trust assets on behalf of your children. You name them in your will. You choose people who understand your values, who are financially capable, and who you trust to make good decisions for your children over many years. You can name a professional trustee alongside a family member trustee to combine personal knowledge of your family with professional financial expertise.
You control the distribution age
The most common structure is for the trust to hold assets until the youngest beneficiary reaches a specified age, often 21, 25, or even later, depending on your assessment of when your children will be mature enough to manage the assets responsibly. You can specify different ages for income distributions and capital distributions. You can build in flexibility for trustees to make earlier distributions for specific purposes such as education, medical needs, or a first home deposit.
You can set conditions and purposes
A well-drafted testamentary trust gives trustees the ability to use trust income and capital for the maintenance, education, and general welfare of the beneficiaries. It can specify that capital distributions are tied to specific milestones. It can protect assets from being dissipated immediately. It can provide for multiple children from the same pool of assets, with trustees having discretion to distribute according to each child’s specific needs rather than rigidly equal shares.
The assets are protected from creditors
Assets held in a properly structured trust are generally protected from the personal creditors of the beneficiaries. If one of your children later faces financial difficulty or a failed business venture, the trust assets are not automatically available to settle their personal debts. This protection lasts for as long as the trust is in operation.
The investment approach can be tailored
Unlike the Guardian’s Fund, trustees of a testamentary trust can invest the trust assets in line with a mandate you set out, or in line with their fiduciary duty to grow the assets appropriately for the long-term benefit of the beneficiaries. The assets can be invested for growth during the years before distribution, preserving and building the real value of the inheritance rather than simply holding it.
Structure 3: Life Insurance Nominated Directly to the Trust
A testamentary trust and a guardian appointment in a will are essential. But they do not solve the liquidity problem that arises in the immediate period after death.
As we discussed in Article 3 of this series, a deceased estate can take 12 to 36 months to administer. During that period, the assets in the estate are frozen. The testamentary trust cannot be properly funded until the estate is wound up and assets are transferred into it. This means that for the first year or more after your death, the trust exists but may have limited liquid assets to draw on for the children’s immediate needs.
The solution is to nominate the testamentary trust as the beneficiary of a life insurance policy. Life insurance proceeds paid to a named beneficiary fall outside the deceased estate entirely. They are paid directly to the nominated beneficiary, which in this case is the trust, relatively quickly after the claim is submitted. The trust is immediately funded with liquid capital that can be used for the children’s needs from the earliest stages, without waiting for the estate to be finalised.
This three-part structure, guardian appointment, testamentary trust, and life insurance nominated to the trust, is the complete answer to the question of how parents protect their minor children through an estate plan. Each element does a job the others cannot do alone.
What Happens in a Blended Family
For parents in blended families, the picture is more complex and the stakes are higher. If you have children from a previous relationship, or if your partner has children from a previous relationship, a standard will that leaves everything to a surviving spouse can produce outcomes that were never intended.
The Stepparent Inheritance Problem
Consider a common scenario. A father with two children from a first marriage remarries. His new wife has one child from her previous relationship. He leaves everything to his wife in his will, trusting that she will provide for all the children appropriately. He dies. His estate passes to his wife. She later remarries. When she dies, her estate, which includes assets that originated with her first husband, passes to her new husband and ultimately to her own biological child. His two children from his first marriage receive nothing.
This is not a malicious outcome. It is the consequence of a will that trusted good intentions rather than building proper structures. Good intentions are not legally enforceable. Structures are.
The Usufruct as a Solution
A usufruct is a legal arrangement that allows a surviving spouse to benefit from assets during their lifetime while preserving the underlying capital for specified beneficiaries, typically the deceased’s biological children. The surviving spouse can live in the family home, receive income from investments, and generally use the assets for their daily needs. But when the surviving spouse dies, the capital passes to the children named in the usufruct, not to whoever the surviving spouse has named in their own will.
A usufruct does not prevent the surviving spouse from being provided for. It prevents the children from being accidentally disinherited through a chain of events that no one intended but that the law allows to happen without the right structures in place.
Separate Testamentary Trusts for Each Set of Children
In some blended family situations, the cleanest solution is to establish separate testamentary trusts for each set of children, funded by ring-fenced assets or insurance proceeds, so that each child’s inheritance is protected from the moment of death regardless of what subsequently happens to the surviving spouse’s estate.
The right structure for a blended family depends on the specific circumstances, the nature of the assets, the ages of the children, and the relationship dynamics. There is no single template. But the need for deliberate, specifically designed structures is universal.
The Questions Every Parent Needs to Answer in Their Will
If you have children under 18, your will needs to address each of the following questions explicitly. If it does not, the law answers them for you, and you will not like the answers.
Who will raise your children if both parents die?
Name a primary guardian and a substitute guardian. Confirm with both that they are willing and prepared. Do not assume.
Who will manage your children’s money?
Name trustees for the testamentary trust. Consider separating the guardian and trustee roles. Consider including a professional trustee alongside a family member for the combination of personal knowledge and financial expertise.
At what age should your children receive their inheritance?
18 is the legal default. It is rarely the right answer. Most parents who think carefully about this choose 21, 25, or a staged approach where income is available earlier and capital is distributed later.
What should the money be used for before distribution?
Maintenance and education are the standard provision. Consider whether you want to add specific provisions for medical care, housing, or other purposes that matter to your family.
What happens to the trust assets if a child dies before receiving their inheritance?
This question makes parents deeply uncomfortable. It is also essential. If a child dies while the trust is still in operation, what happens to their share? Does it pass to their siblings? To their own children if they have any? Back into their own estate? Your will and trust deed need to answer this.
Who steps in if a trustee or guardian cannot continue?
Death, incapacity, and changed circumstances affect trustees and guardians as much as anyone. Name substitutes for every appointment in the will. Build continuity into the structure from the start.
The Conversation You Need to Have Before You Need to Have It
I have sat with parents who are deeply distressed because they never had this conversation with the person they assumed would raise their children. They assumed agreement. The assumed person assumed they were not being serious. Or the assumed person has since moved overseas, or gone through a divorce of their own, or had three more children of their own.
Assumptions about who will raise your children are not estate planning. They are wishful thinking with legal consequences.
The guardian conversation needs to happen directly, explicitly, and with enough detail that the person you are asking genuinely understands what they are agreeing to. It is a significant ask. Most people who are asked directly, with respect and specificity, rise to it. But they need to be asked.
The trustee conversation is different in nature but equally important. Your trustees need to understand what assets they will be managing, on what terms, for whose benefit, and with what powers. A trustee who discovers the scope of the role after your death and was never properly briefed is a trustee who is starting from zero when your children need them to be starting from strength.
Assumptions are not estate planning. Structures written into a valid will are.
How Trinity Board of Executors Helps Parents Get This Right
At Trinity Board of Executors, we work with parents at every stage of this process. We help draft wills that include properly structured testamentary trusts with the flexibility, clarity, and legal precision that your children’s protection requires. We advise on trustee selection, distribution ages, and the specific provisions that reflect your values and your family’s circumstances rather than a generic template.
We also serve as professional trustees where families want the combination of professional accountability and personal knowledge that an independent professional trustee brings to a long-running testamentary trust.
And as professional independent executors, we wind up the deceased estate that funds the trust efficiently and correctly, so the trust is properly capitalised as quickly as the law allows.
Every element of your children’s protection connects to every other element. A will that creates the trust. An executor who funds it. Trustees who manage it. Life insurance that provides immediate liquidity. These are not separate decisions. They are parts of one coherent plan, and they need to be designed together.
Contact Trinity Board of Executors
If you have children under 18 and your will does not include a testamentary trust, a named guardian, and provision for how their inheritance will be managed until they are adults, your estate plan has a gap that needs to be closed.
Contact Trinity Board of Executors today. We will help you build an estate plan that actually does what you intend it to do, protecting your children not just in theory, but in the specific legal and financial structures that make protection real.

Frequently Asked Questions
1. Can I name anyone as a guardian for my children in my will?
You can name any person you choose as guardian in your will, but the appointment is not automatically legally binding. In South Africa, the High Court has ultimate oversight of matters affecting minor children and will consider the best interests of the child above all else. In practice, a named guardian in a will carries significant weight and will typically be respected by the court, provided the named person is willing, suitable, and the appointment is in the child’s best interests. The court is unlikely to override a well-considered guardian appointment made by a parent who knew their child and their circumstances. However, naming a guardian who would clearly not serve the child’s interests, or failing to consult the person before naming them, can create complications. Always confirm the appointment with the person you intend to name before the will is signed.
2. What is the difference between a testamentary trust and a living trust for estate planning purposes?
A living trust, also called an inter vivos trust, is created and operates during your lifetime. It is funded with assets you transfer into it while you are alive, and it continues after your death. A testamentary trust, by contrast, is created by your will and only comes into existence when you die. It is funded with assets from your deceased estate at the conclusion of the estate administration. Each serves different purposes. A living trust can be used to remove assets from your estate during your lifetime for estate duty or asset protection purposes. A testamentary trust is used to manage and protect assets for specific beneficiaries, most commonly minor children, after your death. Many comprehensive estate plans include both, with the living trust handling certain assets during your lifetime and the testamentary trust providing the structure for what remains in your estate at death.
3. What happens to my children if my appointed guardian refuses the role after my death?
If the guardian you named in your will refuses the appointment or is unable to act, the matter is referred to the High Court, which will make an appointment in the best interests of the child. This is why naming a substitute guardian in your will is so important. A substitute guardian steps in automatically if the primary guardian cannot act, without the need for a court process. It is also worth having a candid conversation with your named guardian about what would happen if their circumstances changed, and revisiting the appointment in your will if those circumstances do change. An estate plan is a living set of documents that should be reviewed whenever major life events occur.
4. Can the trustees of a testamentary trust make distributions before the age specified in the will?
This depends on how the trust deed within your will is drafted. A well-structured testamentary trust typically gives trustees discretion to make distributions from trust income, and sometimes capital, for the maintenance, education, medical care, and general welfare of the beneficiaries before the specified distribution age. The distribution age specified in the will usually refers to when the trustees must distribute the remaining capital, not when they can make any distribution at all. This flexibility is one of the key advantages of a testamentary trust over the Guardian’s Fund, which has no such flexibility. The precise powers of the trustees are determined by the wording of the trust deed in your will, which is why professional drafting matters.
5. If both parents die simultaneously, for example in an accident, what happens immediately to the children before the estate is administered?
In the immediate period after both parents die, the practical care of the children typically falls to close family members while the legal process catches up. The named guardian in the will has moral authority from the moment of death, and most family members and institutions, including schools, will cooperate with that appointment informally while the formal process unfolds. However, the guardian does not have full legal authority until the court has formally confirmed the appointment. The estate administration begins as soon as the executor reports the estate to the Master, and the testamentary trust is funded once the estate is finalised. In the interim, life insurance proceeds nominated directly to the trust can provide the guardian with liquid funds for the children’s needs without waiting for the estate to be wound up. This is why the combination of a named guardian, a testamentary trust, and insurance nominated to the trust is the complete answer rather than any one element alone.
