Will vs Trust vs Legacy Asset Locator: What Each One Actually Does

If you've spent any time thinking about estate planning, you've encountered these three terms. They're often mentioned in the same breath — but they do very different things. And confusing them leads to gaps that only become visible at the worst possible time.

Here's a clear breakdown of what each one actually does.

A will: the instruction letter

A will is a legal document that says what you want to happen to your assets after you die. It names an executor to carry out those instructions. It designates guardians for minor children. It comes into effect after death.

What it does:

- Names who inherits specific assets

- Appoints your executor

- Designates guardians for children

- Provides the document probate court uses to supervise distribution

What it doesn't do:

- Take effect during incapacity

- Avoid probate (a will triggers probate, not avoids it)

- Tell anyone where your assets are located

- Cover assets with beneficiary designations, which pass outside the will entirely

Think of a will as the instruction letter you leave behind. Essential. But an instruction letter only helps if the person reading it can find what it's referring to.

A trust: the managed container

A trust is a legal arrangement where assets are held and managed for the benefit of named beneficiaries. A revocable living trust — the most common type in estate planning — is created during your lifetime, can be changed at any time, and continues after your death.

What it does:

- Holds assets outside your personal name

- Allows assets to transfer to beneficiaries without probate

- Keeps the transfer private (unlike probate, which is public)

- Can take effect during incapacity — the successor trustee steps in

- Provides control over how and when assets are distributed

What it doesn't do:

- Automatically include all your assets (a trust only covers what you actually move into it)

- Replace a will (you still need one for anything outside the trust)

- Name guardians for minor children (only a will can do this)

- Tell anyone what accounts exist or where they are

Think of a trust as a managed container with rules about how the contents are handled and who receives them. Effective — but only for the assets you actually put inside it.

A Legacy Asset Locator: the map

A Legacy Asset Locator is not a legal document. It doesn't replace a will or a trust. It does something different — and something the legal documents can't do.

It creates a clear, practical record of what exists and where it is. Across six categories: authority and access, money accounts, insurance and benefits, property, digital presence, and personal and legacy items.

What it does:

- Maps what accounts, policies, properties, and digital assets exist

- Records where documents are stored and who holds authority

- Lists key contacts (attorney, financial advisor, accountant, employer)

- Records digital access information and subscription details

- Provides your executor, POA agent, trustee, or family with a clear starting point

- Gets updated as your life changes

What it doesn't do:

- Replace any legal document

- Store passwords or sensitive credentials

- Transfer assets or grant legal authority

Think of a Legacy Asset Locator as the index to your estate. The will and trust are the chapters. Without an index, the chapters are hard to navigate. Without the chapters, the index has nothing to point to. Both matter — and most people only have one.

How they work together

In practice, the three work as a system:

Most people have a will. Fewer have a trust. Almost nobody has created a clear, shareable map of what they own and where it all lives.

That's the gap the Legacy Asset Locator is designed to fill.

Common questions

Do I need both a will and a trust?

Many people benefit from both. A trust handles the assets you move into it (avoiding probate and providing flexibility). A will covers anything that wasn't moved into the trust and is the only document that can name guardians for minor children. An estate planning attorney can advise on what makes sense for your situation.

If I have a trust, do I still need a Legacy Asset Locator?

Yes. A trust is a legal arrangement for managing and transferring assets. It doesn't tell your successor trustee which accounts exist, what policies you hold, or who your contacts are. The Legacy Asset Locator gives them that practical picture.

What if I only have a will and no trust?

A will alone is a valid starting point, especially for simpler estates. The most important thing alongside it is ensuring your beneficiary designations are current and that your executor has a clear map of what exists — which is where a Legacy Asset Locator becomes particularly valuable.

Is a Legacy Asset Locator legally binding?

No. It is an organisational tool, not a legal document. Its value is practical — giving the right people the information they need to act when legal authority already exists.
