Estate Planning Terms Explained in Plain English: Wills, Trusts, POAs and Probate

Part of the Getting Your Affairs in Order series by Done Once Lab

Estate planning has a jargon problem.

People hear "probate" and assume it's something that only happens to other people. They sign a power of attorney without really understanding when it kicks in. They have a will but don't realise it doesn't help their family find anything.

This guide cuts through the language. It's not exhaustive — it's the terms you're most likely to encounter, explained in plain English, with a note on what actually matters for each one.

Three phases — and which documents belong to each

The clearest way to understand estate planning documents is to see them in context. Different documents apply at different times.

While you're alive and well: This is when you create everything. Decisions made here — beneficiary designations, trust funding, POA appointments — do the heavy lifting later.

Alive but incapacitated: A stroke, a serious accident, a cognitive decline. Your financial and healthcare POAs step in. Your advance directive guides treatment. Your will is irrelevant — it only takes effect after death.

After death: Your will, trust, and beneficiary designations now apply. The executor steps in. Probate may begin. The POAs end.

Most people treat estate planning as one monolithic thing. It's actually three separate conversations, each with its own documents.

The key legal terms

Will

A legal document that says what you want to happen to your assets after you die, names who you want to handle your estate (executor), and designates guardians for minor children. It only takes effect after death and must go through probate. A will does not help anyone find your assets — it says who should receive them, not where they are.

Trust

A legal arrangement where a trustee holds and manages assets for someone's benefit. A revocable living trust is created during your lifetime, can be changed at any time, and typically allows assets to pass to beneficiaries without going through probate. Think of a trust as a locked filing cabinet you control while you're alive — and that your chosen successor can open seamlessly after you're gone, without a court involved.

Financial Power of Attorney (POA)

A legal document allowing someone to manage your finances on your behalf. A durable financial POA remains in effect if you become incapacitated — which is exactly when it's needed. Without one, your family may need court approval to pay your bills or manage your accounts.

Healthcare Power of Attorney

Names a person who can make medical decisions for you if you're unable to communicate them yourself. This person may also be called a healthcare proxy, healthcare agent, or surrogate depending on your state. The document is the power of attorney. The person is the agent.

Advance Directive

The umbrella term for documents that guide your medical care when you can't speak for yourself. It typically includes your living will and healthcare power of attorney. Think of it as the instructions you leave for the doctors and the person you've appointed to speak for you.

Living Will

Specifies your preferences for medical treatment in specific scenarios — life support, resuscitation, end-of-life care. This is about your wishes. The healthcare POA is about who speaks for you. Both matter.

Executor / Personal Representative

The person named in your will to carry out its instructions after death. They gather assets, pay debts, file taxes, and distribute what remains. The job typically takes 9 to 18 months. The executor cannot act until they've been formally appointed through probate.

Beneficiary

The person or entity you name to receive money, property, or benefits from an account, policy, or trust. Beneficiary designations on retirement accounts and life insurance policies override your will — they transfer directly, without probate, to whoever is named on the form. Outdated beneficiary designations are one of the most common estate planning mistakes.

POD / TOD

Payable on Death (POD) applies to bank accounts. Transfer on Death (TOD) applies to investment accounts and securities. Both allow those assets to pass directly to a named person after you die, bypassing probate. Simple to set up. Often overlooked.

Probate

The court-supervised process for validating a will, settling debts, and distributing assets after death. It's public, it takes time (often 9 to 18 months for a typical estate), and it costs money. Assets that have beneficiary designations, TOD/POD registrations, or are held in a trust generally don't go through probate. Assets that don't have any of these — and are in your name alone — typically do.

Trustee / Successor

Trustee The person who manages a trust. If you create a revocable living trust, you're usually the trustee while you're alive. Your successor trustee steps in if you become incapacitated or after you die, managing or distributing the trust assets according to your instructions.

Where the Legacy Asset Locator fits

Notice what's missing from all of the above.

Every document above either says who gets what, or who has authority to act. None of them tell your executor, trustee, or family where your accounts actually are, what subscriptions are running, what devices need access, or who your insurance provider is.

That's the gap. And it's a significant one.

A Legacy Asset Locator is not a legal document. It doesn't replace any of the above. What it does is create a clear, practical map — across all six categories of your financial and digital life — so that when the legal authority kicks in, the person holding it knows where to point it.

Common questions

What's the difference between a will and a trust?

A will takes effect after death and must go through probate. A trust can take effect immediately and allows assets to transfer without probate. Many people use both — a trust for larger assets, and a "pour-over will" to capture anything that wasn't moved into the trust.

Does a power of attorney end when someone dies?

Yes. A power of attorney — including a durable financial POA — ends at death. After that, the executor takes over, once appointed through probate.

If I have a trust, do I still need a will?

Usually yes. A will covers anything that wasn't transferred into the trust, and it's the only document that can name a guardian for minor children.

Can my family access my accounts if I become incapacitated and there's no POA?

Not without court involvement. Being a spouse or adult child is not enough. Without a valid financial POA, a family member would need to apply for a court-appointed conservatorship — which takes time and money. This is one of the strongest reasons to get a POA in place before it's needed.
