The effectiveness of trusts in estate planning depends largely on when protection is required and the level of control needed. While inter vivos and testamentary trusts are both widely used in South African estate planning, their intended purposes differ.

This distinction is often overlooked. Individuals frequently select a form of trust without properly considering timing and control, which ultimately determine whether the trust is appropriate for its intended purpose. Both types of trusts can play a valuable role in estate planning, provided they are applied in the right context.

The key distinction

The key difference is the point at which the establishment takes place. An inter vivos trust is created during the founder’s lifetime and involves the accumulation of property before the founder’s death. On the other hand, a testamentary trust can take effect only upon the founder's death, as provided in a will.

The important point here is not so much the definition, but when control and protection become active. The inter vivos trust has immediate control through the trust deed, which governs the property at present and in the future. The testamentary trust, on the other hand, cannot be established until after the founder’s death.

Inter vivos trusts

An inter vivos trust may be ideal where there is an immediate need for control and protection during one's lifetime.

In practice, an inter vivos trust can -

• provide immediate governance of assets through the trust deed;
• ensure continuity of management in the event of incapacity;
• remove assets from an individual’s personal estate (if structured correctly); and/or
• enable trustees to manage and control assets on an ongoing basis.

In essence, it is a preventative structure that mitigates risk before it materialises.

However, several key considerations should be noted. Inter vivos trusts are not static structures. They require ongoing administration, including trustee involvement, compliance, and financial reporting. Proper management is essential to maintain their validity. In addition, there is a real divestiture of ownership. Assets transferred to the trust no longer belong to the founder, and this separation must be respected to preserve the trust’s integrity. Finally, costs arise from the outset. Establishment, compliance, and administration expenses cannot be deferred and must be accounted for from the beginning.

Testamentary trusts

Where control and protection are only required after death, testamentary trusts play a key role. They are triggered by a future event, namely, the testator's death.

In practice, a testamentary trust is useful when -

• assets should only be distributed upon death;
• a legacy must be structured through a will; and/or
• the use and management of funds need to be clearly prescribed.

Testamentary trusts, however, have limitations. They do not protect an individual’s assets during one’s lifetime, as assets remain within the personal estate and remain under the individual’s control. In addition, they offer limited flexibility, as the provisions and beneficiaries are fixed in the will. In this sense, a testamentary trust is closely tied to the will itself: it reflects the testator’s clear intentions at the time the will is executed and is designed to give effect to those wishes after death. Because of this, it is inherently inflexible - its terms cannot easily adapt to changed circumstances, shifting family dynamics, or evolving financial needs, as it is bound by the original wording and intent recorded in the will.

Planning ahead

When beneficiaries have specific needs or concerns about wealth planning and preservation, early planning becomes essential. The key question remains: does the need for protection lie only in the future, or does it already exist in the present? Importantly, inter vivos and testamentary trusts are not mutually exclusive. Many well-structured estate plans may incorporate both: an inter vivos trust to address current needs and provide protection during a person’s lifetime, and a testamentary trust to cater for future contingencies and ensure continued management of assets after death.

Trusts remain an effective means of estate planning. The effectiveness of a trust depends on the type of trust one chooses. Inter vivos trusts are instant trusts, while testamentary trusts are future-based. Neither is inherently superior; however, the appropriate choice depends on when protection is needed and the level of control required.
