What Is a Trust? A Beginner's Guide to How Trusts Work

Trusts are one of the most powerful tools in estate planning. Yet many people find them confusing or assume they are only for the ultra-wealthy. In reality, trusts serve a wide range of purposes: protecting assets, providing for dependants, ensuring your wishes are carried out efficiently, and in many cases avoiding probate (the legal process of administering a deceased person's estate through the courts).

Most guides explain trusts by listing types - a living trust, a discretionary trust, an offshore trust, and so on. The problem with this approach is that these labels often overlap, and the same trust can go by different names depending on who is describing it.

A more useful way to understand trusts is through their features. Every trust is built from a set of defining features, and understanding each feature helps you understand what a trust can and cannot do, and how different trusts are structured to serve different purposes. A trust you encounter in the real world is simply a combination of these features, tailored to the settlor's specific goals.

What Is a Trust and How Does It Work?

A trust is a legal arrangement where one person (the settlor) transfers ownership of assets to another person or entity (the trustee) to hold and manage on behalf of one or more intended recipients (the beneficiaries). The assets placed into the trust are generally no longer owned by the settlor. Instead, legal ownership is held by the trustee, who manages the assets according to the rules set out in a legal document called the trust deed for the benefit of the beneficiaries or stated purpose of the trust.

The trustee is bound by a fiduciary duty (a legal obligation to act honestly, in good faith, and solely in the interests of the beneficiaries). A trustee who breaches this duty can potentially be held personally liable for any resulting loss.

Trusts are commonly used in estate planning to:

• Control how and when assets are distributed to beneficiaries;

• Protect assets from creditors or legal claims;

• Provide for dependants, including minor children or family members with special needs;

• Avoid or minimise the probate process;

• Maintain privacy over the distribution of an estate.

A trust can hold almost any type of asset such as property, cash, investments, shares, insurance policies, and more.

What Are the Key Features That Define How a Trust Works?

Rather than categorising trusts into rigid types, it is more helpful to understand the key features that define how any trust is structured and how it operates. Every trust is a combination of these features, chosen to match the settlor's intentions and circumstances.

The eight features below are some common ones you will encounter. But depending on the jurisdiction and the complexity of the arrangement, a trust may be shaped by additional features beyond what is covered here.

1. When Does a Trust Take Effect - Living vs Testamentary?

A trust either comes into existence during the settlor's lifetime or upon their death. This single feature shapes everything about when and how the trust operates.

A living trust is created and activated while the settlor is alive. Assets are transferred into the trust immediately, and it begins operating straight away. This is the most common structure for estate planning because it allows the settlor to see the trust in action, make adjustments over time if it is revocable, and ensure a smoother transfer of assets on death without going through probate.

A testamentary trust is written into a Will and only comes into existence when the settlor dies and the Will is executed through probate. It does not exist as a legal structure during the settlor's lifetime. While it does go through probate, it is a useful tool for settlors who want to control how assets are managed for beneficiaries after death, particularly for minor children or staged distributions.

2. Can a Trust Be Changed After It Is Created - Revocable vs Irrevocable?

Whether a trust can be changed after it is set up is one of the most consequential decisions a settlor makes, as it directly affects control, asset protection, and how the trust interacts with the estate.

A revocable trust can be amended, modified, or dissolved by the settlor at any time during their lifetime. The settlor retains full control, which also means the assets can still be considered part of their estate for legal purposes and can remain accessible to creditors.

Once established, an irrevocable trust is generally difficult or cannot be changed unilaterally by the settlor, although modification may still be possible depending on the trust deed and applicable law. When assets are transferred in, they are no longer legally owned by the settlor. This provides stronger asset protection, can potentially remove assets from the taxable estate, and may shield them from personal creditors.

3. How Are Distributions Decided - Discretionary vs Fixed?

This feature determines how much control the trustee has over distributing assets to beneficiaries, and how much certainty the beneficiaries themselves can expect.

In a discretionary trust, the trustee has full discretion over how, when, and how much to distribute to beneficiaries. No beneficiary has a guaranteed entitlement. The trustee exercises judgment based on each beneficiary's needs and circumstances, often guided by a letter of wishes (a non-binding document written by the settlor to guide the trustee on how they would like assets managed and distributed).

A trust deed tells your trustee what they are legally required to do. But it cannot capture the nuance of your intentions - why you made certain decisions, how you want your trustee to interpret grey areas, or what you hope for your beneficiaries beyond the legal terms. That is what a Letter of Wishes is for.

In a fixed trust, each beneficiary's entitlement is predetermined and specified in the trust deed. The trustee has no discretion. They must distribute exactly as instructed. This structure is simpler and more transparent, and is typically used when the settlor has a clear and certain intention about how assets should be divided.

4. Does the Trust Hold Assets Now or Later - Funded vs Standby / Unfunded?

This feature determines when assets actually enter the trust and has significant practical implications for how the trust is managed during the settlor's lifetime.

A funded trust holds assets from the moment it is created. The settlor transfers assets — cash, property, investments, or other holdings — into the trust at the time of establishment, and the trust immediately begins managing them.

A standby or unfunded trust is legally established but holds no or minimal assets until a specific trigger event occurs, such as the settlor's death or a diagnosis of incapacity. A common example is an insurance trust, where the trust deed is put in place during the settlor's lifetime but the insurance payout only flows into the trust upon death. The advantage is that the structure is ready to receive assets exactly when needed, without requiring an immediate transfer.

Whether your trust is funded today or designed to activate later, your executor (the person responsible for carrying out your estate plan after you pass) needs to know it exists — where the deed is held, who the trustee is, and what to do when the time comes.

5. Who Is the Trust Created For - Beneficiary-Based vs Purpose-Based?

Most trusts exist to benefit specific people. But not all of them do, and understanding this distinction helps clarify the full range of what a trust can accomplish.

Most trusts are created for the benefit of named individuals — children, a spouse, other family members, or specific persons the settlor wishes to provide for. These are beneficiary-based trusts, and the trustee's role is to manage and distribute assets in the interests of those individuals.

Some trusts, however, are established not for individuals but for a specific purpose. A charitable trust is created to advance a cause — such as education, poverty relief, or community benefit — and is typically subject to regulatory oversight. A purpose trust is established for a non-charitable but specific objective, such as maintaining a family property, holding shares in a family business, or funding an ongoing project. In both cases, there are no named individual beneficiaries — the trust exists to fulfil its stated purpose.

Your beneficiaries, trustee, co-trustees (where two or more trustees are appointed to manage the trust jointly), and protector (an optional oversight role with powers such as removing or appointing trustees) are some of the most important people in your estate plan. Keeping their details organised and making sure they know their role is just as important as the trust deed itself.

6. Where Is the Trust Established - Onshore vs Offshore?

A trust is governed by the law of the jurisdiction in which it is established, and this choice has meaningful implications for how the trust is regulated, taxed, and enforced.

An onshore trust is established under domestic law — the law of the country where the settlor lives or where the assets are held. It is subject to local regulations, courts, and tax rules.

An offshore trust is established in a foreign jurisdiction — common locations such as the British Virgin Islands, Cayman Islands, Jersey, Guernsey, or Labuan — and is governed by the laws of that jurisdiction. Offshore trusts are typically used by individuals with cross-border assets, international family members, or complex multi-jurisdictional estates. They may offer advantages in terms of asset protection, privacy, and in some cases tax planning, but they carry additional complexity, cost, and compliance obligations.

7. Who Manages the Trust - Individual Trustee vs Corporate Trustee?

The choice of trustee is one of the most consequential decisions in setting up a trust, as the trustee holds legal ownership of the assets and is responsible for managing them according to the trust deed.

An individual trustee is a person — typically a family member, close friend, or trusted adviser. Individual trustees are common in straightforward family trusts. They tend to have personal knowledge of the settlor's wishes and the beneficiaries' circumstances, but they may lack professional expertise, and their ability to act can be affected by their own death, incapacity, or personal circumstances. It is also common to name a replacement or successor trustee (someone designated to step in if the original trustee is unable to continue) to ensure the trust keeps operating without interruption.

A corporate trustee is a licensed professional trust company. Corporate trustees bring expertise, continuity, regulatory oversight, and institutional accountability. They are not subject to the personal risks that affect individual trustees and are often preferred for larger or more complex trusts, long-term structures, or where impartiality is important. The trade-off is cost — corporate trustees charge professional fees for their services.

Many trusts appoint both: an individual trustee for personal knowledge and connection, and a corporate trustee for professional oversight and continuity.

8. How Long Does a Trust Last - Fixed Term vs Perpetual?

The duration of a trust shapes how long the trustee's obligations last and when beneficiaries ultimately receive full control of the assets.

A fixed term trust has a specified end date or vesting condition (the point at which a beneficiary becomes entitled to receive their share of the assets). For example, when the youngest child reaches the age of 30, or after a defined period of 20 years. Once the term ends or the condition is met, the trust winds up and assets are distributed.

A perpetual trust is intended to continue for an extended or indefinite period of time. For example, to hold a family business across generations or to sustain a charitable purpose in perpetuity.

Is a Trust Part of Your Estate Plan?

Understanding how trusts work is an important first step — but knowing whether you need one, and what kind, depends on your personal circumstances, your assets, and your goals for the people you are planning for.

A trust is just one piece of an estate plan. Alongside it, most people also need a Will, a Lasting Power of Attorney, clear records of their assets, and a way to communicate their wishes to the people who will carry them out.

Frequently Asked Questions About Trusts

Q: Do I need to be wealthy to set up a trust?

A: No. While trusts are often associated with large estates, they are used by people across a wide range of financial situations. A trust can be valuable for anyone who wants to control how their assets are distributed, provide for a dependant with special needs, or ensure a smooth transfer of assets without probate.

Q: What is the difference between a Will and a trust?

A: A Will comes into effect only after death and goes through probate before assets are distributed. A trust — particularly a living trust — can operate during the settlor's lifetime and generally allows assets in the trust to bypass probate entirely, resulting in a faster and more private transfer to beneficiaries.

Q: Can one trust have more than one trustee?

A: Yes. A trust can have co-trustees who manage the assets jointly, and it is common to also name a replacement or successor trustee to step in if the original trustee is unable to continue. Some trusts appoint both an individual and a corporate trustee to combine personal knowledge with professional oversight.

Q: Can a trust be changed after it is set up?

A: It depends on whether the trust is revocable or irrevocable. A revocable trust can be amended or dissolved by the settlor at any time during their lifetime. An irrevocable trust generally cannot be changed without the consent of the beneficiaries.

Q: Does a trust avoid probate?

A: A properly structured living trust generally allows assets held within it to bypass probate, as those assets are generally held by the trustee under the trust structure rather than in the deceased individual's personal name. A testamentary trust, however, is created through a Will and does go through probate before it is activated.
