Wills and trusts are two of the most common estate planning tools, but they serve different purposes. Understanding those differences can help you make better decisions about how your property will be managed, who will make decisions if you become unable to do so, and what will happen to your assets after your death.
One of the most important things to understand is that choosing between a will and a trust isn’t always an either-or decision. Many well-designed estate plans include both.
The right approach depends on your assets, family circumstances, goals, and the laws that apply to your situation. An estate planning attorney can help you determine which documents make sense for you and make sure they work together as part of a coordinated plan.
Wills vs. Trusts: The Key Differences
At a basic level, a will provides instructions for what should happen after your death. A trust can be used to hold and manage assets during your lifetime as well as provide instructions for managing and distributing those assets after your death.
Some of the most important differences include:
When they take effect. A will generally takes effect at death. A living trust can operate during your lifetime and continue after your death.
Probate. Assets passing under a will generally go through probate. Assets properly titled in certain trusts may pass outside the probate process.
Privacy. Because probate is a court proceeding, information involved in the probate estate may become part of the public record. Assets administered through a trust outside probate can generally remain private.
Incapacity planning. A properly designed and funded living trust may allow a successor trustee to manage trust assets if you become unable to manage them yourself. A will does not take effect during incapacity.
Control over distributions. A trust can provide detailed instructions about when and how beneficiaries receive assets, rather than requiring an outright distribution.
Complexity. A trust generally requires more work to establish and maintain because assets often need to be properly titled or transferred into the trust.
Neither document is automatically “better.” The question is what combination of estate planning tools best accomplishes your goals.
What Does a Will Do?
A last will and testament states how you want certain property handled after your death and identifies the people you want to carry out those instructions.
Depending on your circumstances, a will can:
- Name the person who will administer your estate.
- Identify who should receive property passing through your estate.
- Nominate guardians for minor children.
- Provide instructions for certain personal property.
- Establish testamentary trusts that take effect after your death.
A will is an important estate planning document, but it does not control everything you own.
For example, some assets may pass according to beneficiary designations, joint ownership arrangements, transfer-on-death provisions, or the terms of a trust rather than under your will. That’s one reason estate planning involves more than simply preparing a will.
Does a Will Avoid Probate?
Generally, no.
A will provides instructions for administering property that is subject to probate; it does not itself avoid probate.
Probate is the court-supervised process used to administer an estate, resolve certain claims and transfer property after death. Whether probate is required—and which assets are involved—depends on how property is owned, beneficiary designations, applicable state law and other circumstances.
For some families, probate is manageable. For others, avoiding or minimizing probate is an important estate planning goal.
What Is a Pour-Over Will?
People who establish a revocable living trust commonly have a type of will known as a pour-over will.
Its purpose is to direct certain assets that remain outside the trust at death into the trust through the estate administration process.
A pour-over will is also a reminder of an important point: simply creating a trust isn’t enough. A trust must be properly coordinated with the rest of your estate plan.
What Is a Living Will?
Despite its name, a living will serves a very different purpose from a last will and testament.
A living will is a type of advance directive dealing with healthcare wishes. It can provide instructions about medical treatment in circumstances in which you cannot communicate your wishes yourself.
Advance healthcare planning may also include documents that authorize another person to make healthcare decisions for you when necessary.
These documents are an important part of a complete estate plan because estate planning isn’t only about what happens after death. It should also address what happens if you are alive but unable to make or communicate decisions.
What Does a Trust Do?
A trust is a legal arrangement under which property is held and managed according to the terms of the trust.
Trusts can serve many different purposes. Depending on the type of trust and how it is structured, a trust may be used to:
- Manage assets during your lifetime.
- Provide for management of assets if you become incapacitated.
- Provide instructions for beneficiaries after your death.
- Control when and how beneficiaries receive property.
- Provide additional protection for a beneficiary who is young, has a disability or needs assistance managing money.
- Avoid probate for certain properly titled assets.
- Address specific tax, asset-protection or long-term-care planning goals.
There are many types of trusts, and they are not interchangeable. The appropriate trust depends on what you are trying to accomplish.
What Is a Revocable Living Trust?
A revocable living trust is one of the most familiar types of trusts used in estate planning.
The person creating the trust—often called the grantor, settlor or trustmaker—typically retains significant control over the trust during life and may generally amend or revoke it while competent.
The creator may also serve as the initial trustee and continue managing the trust property.
A properly designed revocable trust can also name a successor trustee to step in when necessary. This can make a revocable trust an important incapacity-planning tool as well as a way to manage and distribute assets after death.
However, a revocable living trust only controls assets that are subject to the trust. Creating the document without properly coordinating ownership of assets may prevent the trust from accomplishing its intended purpose.
What Is an Irrevocable Trust?
An irrevocable trust is different.
Generally, the person creating an irrevocable trust gives up rights or control that would have been retained with a revocable trust. The specific rules depend heavily on the type of trust and its terms.
Irrevocable trusts can be used for specialized estate planning purposes, including certain asset-protection, tax, special needs and long-term-care planning strategies.
For example, certain irrevocable trusts may play a role in planning for future long-term-care costs and Medicaid eligibility. These strategies are complex, however, and timing, ownership, state law and Medicaid rules matter.
An irrevocable trust should therefore be created as part of a carefully considered legal strategy rather than simply as a way to “protect assets.”
What Is a Testamentary Trust?
A testamentary trust is created through a will and comes into existence after the person who made the will dies.
These trusts may be useful when a beneficiary should not receive an inheritance outright.
For example, a testamentary trust might be used to manage an inheritance for a minor child or another beneficiary who needs assistance managing assets.
Because the trust is created through the will, the estate generally must go through the probate process before the testamentary trust can be established and funded.
What Assets Can Go Into a Trust?
Depending on the type of trust and the purpose of the estate plan, many types of assets can potentially be held in a trust, including:
- Real estate
- Bank and investment accounts
- Stocks, bonds and mutual funds
- Business interests
- Valuable personal property
- Certain intellectual property interests
But not every asset should automatically be retitled to a trust.
Retirement accounts, life insurance, jointly owned property, payable-on-death accounts and other assets may be coordinated with an estate plan through ownership arrangements or beneficiary designations rather than by simply transferring them into a trust.
This is one reason funding and maintaining a trust should be done with professional guidance. The trust document, asset ownership and beneficiary designations should work together.
Will vs. Trust: Which Is Right for You?
The answer depends on what you need your estate plan to accomplish.
A will may be an essential part of your plan if you need to name guardians for minor children, identify beneficiaries, name an executor or provide instructions for property passing through your estate.
A trust may be particularly useful if you want to:
- Avoid probate for certain assets.
- Provide continuity in the management of assets during incapacity.
- Keep certain estate matters private.
- Control how and when beneficiaries receive an inheritance.
- Plan for a beneficiary with special needs.
- Address more complex family, asset or long-term-care circumstances.
Your age or the dollar value of your estate alone shouldn’t determine the answer. Family relationships, types of assets, incapacity concerns, beneficiary needs and your long-term goals can be just as important.
Do You Need Both a Will and a Trust?
Many people do.
Even when a revocable living trust is the centerpiece of an estate plan, a will may still perform important functions. Likewise, having a will doesn’t eliminate the potential value of a trust.
The documents should be designed to work together—not created independently without considering how one affects the other.
And neither a will nor a trust is a complete estate plan by itself.
A comprehensive plan may also include powers of attorney, healthcare directives, beneficiary designations and other documents designed to address both incapacity and death.
Estate Planning Is About More Than Documents
One of the biggest estate planning mistakes is treating the process as a checklist of documents: get a will, sign a power of attorney and you’re finished.
Effective estate planning begins with your life.
Who depends on you? Who would make decisions if you couldn’t? How is your property owned? Who should manage your finances? What happens if a beneficiary has a disability, is financially inexperienced or receives public benefits? What would happen if you needed long-term care?
The answers help determine which legal tools belong in your plan.
Your plan should also be reviewed periodically. Changes in your family, finances, health, property, beneficiary relationships and the law can all affect whether an older estate plan still accomplishes what you intended.

Missouri and Kansas each have their own laws governing wills, trusts, probate and estate administration. For families in the Kansas City area, that can be especially important when family members or property are located on both sides of the state line.
