Trusts 101: How They Work and Which Type You Need

What Is a Trust, Exactly?

A trust is a legal arrangement with three roles: the grantor (who creates the trust and contributes assets to it), the trustee (who manages those assets according to the trust's terms), and the beneficiary (who ultimately benefits). Many people serve as their own trustee while alive and able, with a successor trustee named to take over later.

A trust only controls assets actually retitled into its name; a common, costly mistake is creating the document but never "funding" it by transferring accounts, property, or other assets into it.

Trusts vs. Wills: Why the Difference Matters

It's worth being clear about what a trust adds that a will alone doesn't. A will only takes effect after death and typically must pass through probate, a court-supervised process that validates the will, settles debts, and distributes assets, which can take months and becomes part of the public record. A properly funded trust bypasses probate entirely for the assets it holds, keeps distribution details private, and can provide instructions for managing assets if the grantor becomes incapacitated while still alive, something a will can't do, since it only applies after death.

Revocable (Living) Trusts

How They Work

A revocable, or living, trust can be changed or dissolved by the grantor at any time while alive. Assets in it are still legally considered the grantor's own, so there's no special tax treatment and no protection from creditors or lawsuits.

What They're Good For

The main benefits are avoiding probate, the often slow, public court process of distributing an estate, and providing a built-in plan if the grantor becomes incapacitated, since a successor trustee can step in immediately without a court proceeding.

What They Don't Do

A revocable trust doesn't reduce estate taxes or protect assets from creditors or lawsuits, since the grantor still fully controls and legally owns everything inside it.

Irrevocable Trusts

How They Work

An irrevocable trust generally can't be changed or dissolved once created, aside from narrow legal exceptions. In exchange for that flexibility, the assets are legally removed from the grantor's estate.

What They're Good For

Because the assets are no longer considered the grantor's, irrevocable trusts can offer real creditor and lawsuit protection, potentially reduce estate taxes for large estates, and support Medicaid planning strategies (though these come with the same five-year look-back rules discussed elsewhere in Medicaid planning).

The Trade-Off: Giving Up Control

This protection isn't free: once assets go into an irrevocable trust, the grantor typically can't take them back or change the terms unilaterally. It's a meaningful decision, not a paperwork formality, which is why it's usually reserved for specific goals rather than a default choice.

Common Types of Trusts You Might Hear About

Living trust, a general-purpose revocable trust used mainly to avoid probate

Testamentary trust, created through a will and only takes effect after death, often used to manage an inheritance for minor children

Marital or QTIP trust, provides income to a surviving spouse while controlling where assets go afterward, common in blended families

Special needs trust, allows a beneficiary with a disability to receive support without jeopardizing eligibility for public benefits

Irrevocable life insurance trust (ILIT), owns a life insurance policy so the payout isn't counted as part of the taxable estate

Charitable remainder trust, pays income to the grantor or a beneficiary for a period of time, with the remainder eventually going to a chosen charity

Do You Actually Need a Trust?

For most families, a well-drafted will covers the basics. A trust becomes worth considering if you want to avoid probate or keep estate details private, have minor children or a beneficiary with special needs, are part of a blended family and want more control over who inherits what and when, own real estate in more than one state (which can otherwise mean probate in each state), or have an estate large enough that estate tax planning is relevant. As of 2026, the federal estate tax exemption is substantial, $15 million for individuals and $30 million for married couples, so estate-tax-motivated irrevocable trusts are relevant to a relatively small share of households, even though probate-avoidance and incapacity-planning reasons for a revocable trust apply much more broadly.

How Much Does a Trust Cost and How Do You Set One Up?

Working with an estate planning attorney to draft a trust typically costs more upfront than a simple will, reflecting the added complexity, but the real work isn't just the document. Funding the trust (retitling bank accounts, investment accounts, and real estate into its name) is what actually makes it effective, and it's a step people frequently skip or do incompletely. Low-cost DIY trust templates exist, but the funding step and state-specific rules make this an area where a mistake can be costly to fix later, a short attorney consultation is often worth it even if you handle some of the process yourself. Review your trust every few years, and after any major life event, to make sure it still reflects your wishes.

A Simple Way to Think About the Decision

If you're unsure where to start, ask three questions in order. First: do I mainly want to avoid probate and have a plan for incapacity? If yes, a revocable living trust is likely worth exploring. Second: do I have a specific protection or tax goal, a beneficiary with special needs, a blended family, or an estate large enough that estate tax is a real concern? If yes, an irrevocable trust built around that goal may be worth a conversation with an attorney. Third: is my situation fairly simple, no minor children, no blended family complications, a modest estate? If so, a well-drafted will may genuinely be enough, and a trust may be more complexity than you need right now. None of these answers are permanent; your estate plan should evolve as your life does.

Trusts and Charitable Giving

For families already thinking about legacy and giving, certain trusts do double duty. A charitable remainder trust, for example, can provide income to you or a beneficiary for a set period, offer an upfront partial tax deduction, and ultimately direct the remaining assets to a charity of your choice, a structured way to combine current income needs with a longer-term giving goal. This is a more specialized tool than most families need, but it shows how trusts can be built around specific values, not just tax minimization.

Mistakes That Undermine a Trust

The most common trust mistake, by far, is failing to fund it: creating the document but never actually retitling accounts, real estate, or other assets into the trust's name. An unfunded trust provides none of its intended benefits, since it legally holds nothing. Other frequent missteps: forgetting to update beneficiary designations on retirement accounts and life insurance (which generally pass outside the trust regardless of what the trust document says), naming a successor trustee who isn't realistically able or willing to take on the responsibility, and never revisiting the trust after a major life change like a divorce, a new grandchild, or a move to a state with different trust laws.

Working through a funding checklist with your attorney when the trust is created, rather than assuming it happens automatically, is the single most effective way to avoid this problem.
