A will directs how your property is distributed after you die and names an executor and, if needed, a guardian for minor children. A trust is an arrangement in which a trustee holds and manages assets, often letting the estate skip probate and stay private. Most people need a will at minimum, and some need both.
If you already know you want to protect your family without a long court process, you can start building your will online today. If you are comparing structures for a larger or more complex estate, keep reading, because the right answer depends on what you own and who you want managing it.
What a Will Does
A will, sometimes called a last will and testament, is a legal document that outlines a person's wishes regarding the distribution of their assets after they die. According to Cornell Law School's Legal Information Institute, a valid will generally must be in writing, signed by the testator, and witnessed, and the person making it must have legal capacity and clear intent. A will also:
- Names an executor to manage the estate and carry out your wishes
- Lets you name a guardian for minor children, which no other document can do
- Must go through probate, the court process that validates the will and oversees distribution
- Becomes part of the public record once it is filed with the probate court
Probate is not necessarily slow or difficult, but it is public. Court records from probate, including the value of assets and who inherited them, are generally available to anyone who asks, according to guidance from state court systems such as the California Courts self-help center. If privacy matters to you, that is one reason people add a trust to their plan.
What a Trust Does
A trust is a legal arrangement in which you (the grantor) transfer assets to a trustee, who manages those assets for one or more beneficiaries. Cornell's Wex legal dictionary defines a trust as a division of property rights in which legal ownership passes to a trustee while the beneficiary retains the benefit of the assets. A trust can be created during your lifetime or through your will, and it can manage assets both while you are alive and after you die.
Unlike a will, assets properly titled in a trust generally do not pass through probate. That keeps the transfer private and can speed up how quickly beneficiaries receive their inheritance. For a closer look at how that works, see our guide on whether a revocable trust actually avoids probate. Trusts are also useful for managing money for minor children or beneficiaries who are not ready to handle a lump sum, since the trustee can release funds on a schedule you set.
Revocable Trusts vs Irrevocable Trusts
There are two main categories of trust, and the difference matters for control, taxes, and asset protection.
- Revocable (living) trust: You create it during your lifetime and can change, amend, or cancel it at any time. You typically remain the trustee and keep full control of the assets while you are alive. Because you retain control, a revocable trust does not shield assets from your own creditors and does not by itself reduce estate taxes.
- Irrevocable trust: Once created, it generally cannot be changed or revoked, and you give up ownership and control of the assets you transfer into it. In exchange, an irrevocable trust can offer stronger creditor protection and, depending on how it is structured, can help reduce the value of your taxable estate.
Choosing between the two, or using both, depends on your goals: control and flexibility favor a revocable trust, while asset protection and tax planning often point toward an irrevocable one.

A Worked Example: Blending a Will and a Trust
Consider a parent with a home, a brokerage account, and two young children. They create a revocable living trust and retitle the home and investment account in the trust's name, naming themselves as trustee during their lifetime and a sibling as successor trustee. They also sign a pour-over will that names a guardian for the children and directs any asset accidentally left outside the trust into it. If they die, the trust assets pass to the trustee for the children's benefit without probate, while the will still handles guardianship and any stray property. Neither document alone would have covered both needs.
How FastWill Handles This
FastWill lets you build a state-compliant will in minutes, and if your situation calls for a trust as well, our trust package walks you through funding it correctly, which is the step many people skip. You answer plain-language questions, and the documents update automatically as your answers change, so you are not stuck interpreting statutes on your own.
Common Mistakes to Avoid
- Creating a trust but never funding it. A trust only controls assets that are actually retitled into its name. An unfunded trust does nothing.
- Assuming a trust replaces a will. If you have minor children, you still need a will to name a guardian.
- Choosing irrevocable without understanding the tradeoff. Giving up control is permanent, so confirm the tax or asset protection benefit is worth it before you sign.
Frequently Asked Questions
Do I need both a will and a trust?
Not always. Many people only need a will, especially if their estate is modest and probate in their state is not a major concern. A trust becomes more useful for larger estates, blended families, minor children's inheritances, or anyone who wants to avoid probate and keep the estate private.
Is a trust more costly to set up than a will?
A trust typically involves more steps than a will because you have to draft the trust document and then retitle assets into it. A will alone is simpler and quicker to put in place.
Does a trust avoid estate taxes?
A revocable trust generally does not reduce estate taxes on its own, since you still control the assets. An irrevocable trust may reduce the taxable estate, but only if structured and funded correctly, so confirm your approach with a tax professional if this matters to you.
What happens if I die without either document?
Your state's intestacy laws decide who inherits, and a court appoints someone to administer your estate. You lose the ability to choose your executor, trustee, guardian, or beneficiaries.
Can I change my mind after creating a trust?
Yes, if it is a revocable trust. You can amend or dissolve it at any time while you are alive and have capacity. An irrevocable trust cannot be changed once it is signed and funded, with rare exceptions.
