Wills, Living Wills, and Trusts: What’s the Difference and Which Do You Need?

If you have a bank account, a home, a 401(k), or people you care about, you have an estate. The question is whether you or state law decides what happens to it. Here’s a plain-English guide to three documents that are often confused.

The Living Will: Your Medical Wishes

Despite its name, a living will has nothing to do with property. It spells out the medical care you do or don’t want if you can’t speak for yourself, such as life support. It’s usually paired with a healthcare power of attorney, which names someone to make medical decisions for you. Together, they spare your family from guessing during a painful time.

Bottom line: Every adult should have one.

The Last Will and Testament: The Foundation

A will directs who receives your property, names an executor, and, for parents, names a guardian for minor children. But a will must go through probate, a court process that can be slow, costly, and public. It also does nothing if you become incapacitated.

Bottom line: The baseline document for nearly everyone, and the only place to name a guardian for your children.

The Revocable Living Trust: Flexibility and Privacy

With a revocable trust, you move assets into a trust you control, usually as your own trustee. You can change or cancel it anytime. Benefits include:

• Avoiding probate, so assets pass to heirs faster and privately.
• Planning for incapacity, with a successor trustee stepping in without court involvement.
• Simplifying multi-state property, avoiding probate in each state.

A revocable trust doesn’t reduce estate taxes or protect assets from creditors. And it only works if its funded, meaning assets are retitled into the trust. An unfunded trust is a common and costly mistake.

The Irrevocable Trust: Protection and Tax Planning

An irrevocable trust generally can’t be changed once created. You give up control of the assets, and that’s what creates the benefits:

• Estate tax reduction. The federal exemption is $15 million per person in 2026, but some states set much lower thresholds.
• Creditor protection, since you no longer own the assets.
• Long-term care planning for Medicaid eligibility, subject to a five-year look-back.
• Special situations, like supporting a loved one with special needs or holding life insurance outside your estate.

The trade-offs are loss of flexibility, complex administration, and often a separate tax return.

A Special Note for 401(k)s or IRAs

Your 401(k) doesn’t pass through your will or trust. It goes to whoever is named on your beneficiary designation form, even if your will says otherwise. A few tips:

• Review it after major life events like marriage, divorce, or birth. Outdated forms regularly send money to ex-spouses.
• Name contingent beneficiaries in case your primary beneficiary dies first.
• Know the spousal rule. If you’re married, naming someone other than your spouse usually requires your spouse’s written consent.
• Be thoughtful about naming a trust. Under the SECURE Act, most non-spouse beneficiaries must empty inherited accounts within 10 years, so the trust must be drafted carefully.

Which Do You Need?

Most people need a living will, healthcare and financial powers of attorney, a will, and current beneficiary designations. A revocable trust is worth considering to avoid probate or plan for incapacity; an irrevocable trust fits more specialized goals.
