Will vs. Trust 2026: Key Differences, Costs and Which One You Actually Need

Wills and trusts are the foundation of estate planning. Each serves different purposes, and most people benefit from having both. A will tells the court how to distribute your assets after you die. A trust holds assets on behalf of your beneficiaries and can work both during your lifetime and after death — avoiding the court system for the assets it holds.

The biggest practical difference comes down to this: a will goes through probate (a court process whose cost and timing depend on your state and the estate), while assets that were properly transferred into a revocable living trust generally pass without probate. For a family with a home to pass on, that distinction can save heirs court costs and waiting.

Here’s a detailed comparison to help you decide which tools you need.

Wills vs. Trusts: Side-by-Side Comparison

The table below covers the core differences between a standard last will and testament and a revocable living trust — the most common type of trust used in personal estate planning. For a deeper dive into the differences between revocable and irrevocable trusts, see our revocable vs. irrevocable trust guide.

A few of these differences deserve extra attention. Privacy is something many people overlook — a will that goes through probate is generally filed with the court, where it can become part of the public record. A trust usually is not filed, so the details tend to stay private, though some trust-related documents can still be public. This is particularly important for families with significant assets or blended family situations where disputes are more likely.

Incapacity planning is another major advantage of trusts. If you become mentally incapacitated (due to dementia, a stroke, or an accident), a will does nothing — it only takes effect after death. Without a trust, your family would need to go to court to obtain a conservatorship to manage your finances, which is expensive, time-consuming, and public. With a revocable living trust, your named successor trustee can step in immediately and manage your assets without court involvement. You should also have a power of attorney and advance directive as part of your complete estate planning documents.

Multi-state property is where trusts provide the clearest financial advantage. If you own a vacation home in another state, your estate could face probate in both your home state and the state where the property is located — known as ancillary probate. Each probate proceeding has its own attorney fees and court costs. Property held in a trust can avoid it.

Types of Trusts

Not all trusts work the same way. The right type depends on your goals — whether you’re focused on avoiding probate, protecting assets from creditors or lawsuits, reducing estate taxes, or providing for a family member with special needs. Here’s how the most common types compare.

A revocable living trust is the most common and the one most people mean when they say “I need a trust.” You maintain full control of your assets during your lifetime, can change or revoke the trust at any time, and it converts to an irrevocable trust upon your death. For a step-by-step walkthrough of setting one up, see our living trust guide.

An irrevocable trust is a more powerful tool, but it comes with a major tradeoff: once you transfer assets into it, you give up control. The assets are no longer legally yours, which is exactly why they’re protected from creditors, lawsuits, and estate taxes. Irrevocable trusts are worth considering if your estate exceeds the federal estate tax exemption ($13.99 million per individual in 2026) or if you’re in a profession with high lawsuit risk. For a detailed comparison, see revocable vs. irrevocable trusts.

A special needs trust is essential for families supporting a disabled child or adult who receives government benefits like Medicaid or SSI. Leaving money directly to a disabled beneficiary — even through a well-intentioned inheritance — can disqualify them from these benefits. A properly structured special needs trust provides supplemental support without affecting eligibility.

The Cost Comparison: Trust vs. Probate

The most common objection to creating a trust is the upfront cost. A trust usually costs more to set up than a simple will, but the setup cost is only part of the picture: a will leaves your family a probate process after you die.

How probate fees work in some states

Probate costs vary widely by state and estate, so no single percentage fits everyone. In some states, attorney and executor fees are set by statute as a percentage of the estate’s gross value — not net equity. That means even if you have a $400,000 mortgage on a $500,000 home, the fee is calculated on the $500,000 figure. In California, for example, the statutory attorney fee on a $500,000 estate is $13,000 (4% of the first $100,000, 3% of the next $100,000 and 2% of the next $300,000), and the executor’s statutory fee follows the same schedule — $26,000 together, before court costs or extraordinary fees. Many other states use “reasonable fee” rules instead, so ask a local probate attorney what applies to you.

Beyond the dollar costs, there’s the time burden on your family. While an estate is in probate, your heirs may be unable to sell your home or distribute assets until the court-appointed personal representative has authority to act. If your surviving spouse or children depend on those assets for living expenses, that delay can cause real hardship. Assets held in a trust can be managed and distributed by the successor trustee without waiting for probate, though the trust’s terms and your state’s rules still apply.

Who Needs What

The right estate planning setup depends on the complexity of your finances, your family situation, and how much you value privacy and speed of asset transfer. Here are practical guidelines to help you decide.

Will Only (Simple Estate)

You may only need a will if:

• Assets are under $100,000
• You don’t own real estate
• Most assets have beneficiary designations (retirement accounts, life insurance)
• You’re young and single with few assets
• You want to name a guardian for children (will still needed with a trust)

Even with a simple estate, every adult should have a will. Dying without one (called “intestate”) means your state’s default laws decide who gets your assets — which may not align with your wishes at all. A surviving partner who isn’t legally married receives nothing under intestate laws in most states. For guidance on creating one, see how to write a will.

Trust + Will (Recommended for Most)

You likely need a trust if:

• You own a home
• Assets exceed $100,000
• You value privacy (don’t want assets public record)
• You own property in multiple states
• You want to avoid probate delays for your family
• You want protection during incapacity

The most common setup is a revocable living trust paired with a pour-over will. The trust holds and manages your major assets (home, investments, bank accounts). The pour-over will acts as a safety net, directing any assets you forgot to transfer into the trust to be “poured over” into it after your death. The will is also where you name guardians for minor children — something a trust cannot do.

If your net worth is above $100,000 (the median net worth for Americans age 35+ is well above this threshold), a trust is worth pricing out. Compare attorney quotes for the trust against what probate would cost in your state.

How to Fund a Trust

Creating a trust isn’t enough—you must transfer assets into it (called “funding”). Assets not in the trust still go through probate. This is the most critical step in the trust process, and it’s the one people most often skip.

Common mistake: Creating a trust but never funding it. An unfunded trust provides no probate avoidance.

A few important nuances on funding: Retirement accounts (401(k)s, IRAs) should generally not be retitled into a trust. Doing so can trigger an immediate taxable distribution of the entire account. Instead, name the trust as a beneficiary — but only after consulting with an estate attorney, because naming a trust as the beneficiary of a retirement account can affect the required minimum distribution timeline for your heirs. In most cases, naming individuals as primary beneficiaries and the trust as a contingent beneficiary is the better approach.

For life insurance policies, whether to name the trust or individuals as beneficiaries depends on the size of your estate. If your estate is below the federal estate tax exemption, naming individuals directly is simpler and avoids any complications. If your estate is large enough to face estate taxes, an irrevocable life insurance trust (ILIT) can remove the death benefit from your taxable estate entirely.

Bank and brokerage accounts are straightforward — contact your bank and ask to retitle the accounts in the name of your trust (e.g., “John Smith, Trustee of the John Smith Revocable Living Trust dated March 1, 2026”). Most banks can process this in a single branch visit.

Real estate requires recording a new deed with the county. Your attorney can prepare this as part of the trust creation process. If you have a mortgage, check with your lender first — though the federal Garn-St. Germain Act bars a lender from calling a loan due when a home with fewer than five dwelling units is transferred into a living trust in which you remain a beneficiary and which does not transfer occupancy rights, it’s still good practice to notify them.

Review your trust funding annually. It’s easy to open a new bank account or purchase an asset and forget to title it in the trust’s name. Building a trust review into your annual estate planning checklist keeps everything current.

The Bottom Line

Everyone needs a will. If you own a home or have $100,000+ in assets, adding a revocable living trust can keep the assets you transfer into it out of probate, can add privacy, and lets a successor trustee manage your affairs during incapacity. Compare the upfront cost with what probate would cost in your state. Use both together: a trust for asset management and a pour-over will for anything the trust doesn’t cover and to name guardians for children.

The most important thing is to take action. According to surveys, more than half of American adults don’t have any estate planning documents in place. Whether you start with a simple will or a complete trust package, having a plan in place protects your family and ensures your wishes are carried out — not the state’s default rules.
