Ask people about estate planning and you’ll hear strong opinions. Some say everyone needs a living trust to avoid probate. Others say a simple will is plenty. Both can be right, depending on your circumstances.
This guide explains how wills and revocable living trusts work, how they differ, and the questions that usually decide which one fits. Estate law varies significantly by state, so treat this as a starting point for a conversation with an estate planning attorney.
Key takeaways
- A will takes effect only at death and usually goes through probate, a court-supervised process.
- A revocable living trust can hold your assets during life and pass them on at death without probate.
- A trust only controls assets you actually transfer into it. Unfunded trusts are a common, costly mistake.
- Only a will can name a guardian for minor children.
- Many people use both: a living trust plus a “pour-over” will as a safety net.
What is a will?
A will, sometimes called a last will and testament, is a legal document that says:
- Who should receive your property when you die
- Who will manage your estate (your executor or personal representative)
- Who will care for your minor children (a guardian)
To be valid, a will must meet your state’s formalities. These usually include being in writing, signed by you and witnessed by two adults. Some states also accept handwritten wills or allow “self-proving” affidavits to simplify probate.
A will doesn’t take effect until death, and you can change or revoke it at any time while you have capacity.
Wills and probate
Most property passing under a will goes through probate. In probate, a court confirms the will is valid, the executor is formally appointed, creditors are notified and paid, and the remaining property is distributed. Depending on the state and the estate, probate can be fairly simple or can take a year or more and involve significant legal fees. Probate filings are generally public records. See how probate works and how to avoid it.
What is a living trust?
A revocable living trust is a legal arrangement you create during your lifetime. You (the grantor) transfer assets to the trust, and a trustee manages them for the beneficiaries. Usually you serve as your own trustee while you’re alive, so day to day nothing changes: you keep full control and can amend or revoke the trust at any time.
You also name a successor trustee, who takes over if you die or become incapacitated. At your death, the successor trustee distributes or manages the trust assets according to your instructions, generally without going through probate.
The main differences
Probate
This is the biggest practical difference. Assets in a properly funded living trust avoid probate. Assets passing under a will usually don’t. How much that matters depends on your state: probate is notably expensive and slow in some states and relatively streamlined in others. Many states also have simplified procedures for small estates.
Privacy
A probated will generally becomes a public record, as does the inventory of assets in some states. A trust typically stays private.
Incapacity
A will does nothing if you become unable to manage your affairs during life. With a living trust, your successor trustee can step in and manage trust assets without a court guardianship or conservatorship. (A durable power of attorney covers assets outside the trust.)
Property in more than one state
If you own real estate in more than one state, a will may require a separate “ancillary” probate in each one. Putting that property in a trust can avoid it.
Cost and effort
A will is usually cheaper to prepare. A trust costs more upfront and requires you to fund it by retitling assets, such as recording a new deed for your home and changing the name on bank and investment accounts. The effort is front-loaded, while probate costs fall on your family later.
Guardianship of children
Only a will can nominate a guardian for minor children. A trust can manage money for children, but you still need a will to name who will raise them.
Challenges
Both can be contested, for example on grounds of lack of capacity or undue influence. A trust that has been in operation for years may be somewhat harder to challenge in practice, but neither is immune.
Common misconceptions
“A trust protects my assets from creditors.” A revocable trust doesn’t. Because you can take the assets back, creditors generally can reach them during your life. Asset protection requires different, irrevocable planning.
“A trust saves estate taxes.” A standard revocable living trust doesn’t reduce estate taxes by itself. Tax planning for large estates uses specific provisions and other trust types. Most estates are below the federal estate tax exemption, though some states have their own estate or inheritance tax with lower thresholds.
“If I have a trust, I don’t need a will.” You still need a “pour-over” will to catch any assets you forgot to transfer and to name guardians for children.
“My will covers everything.” Some assets pass outside a will entirely, including life insurance and retirement accounts with named beneficiaries, jointly owned property with survivorship rights, and payable-on-death bank accounts. Keep beneficiary designations up to date, because they usually override your will.
Which one do you need?
A will may be enough if:
- Your estate is modest, and your state has simple probate or small-estate procedures
- Most of your assets already pass by beneficiary designation or joint ownership
- Your main goal is naming a guardian for young children
- You want a lower upfront cost
A living trust may be worth it if:
- You own a home or other real estate, especially in more than one state
- You live in a state where probate is expensive or slow
- Privacy is important to you
- You want a smooth plan for possible incapacity
- You want to control how and when heirs receive money, for example in stages
- You have a blended family, a beneficiary with special needs or other complex situations
Frequently asked questions
Can I write my own will?
Yes, and many states accept do-it-yourself wills that meet the legal formalities. The risks are mistakes in signing, ambiguous wording and failing to plan for changes in circumstances. Errors are discovered only after death, when they can’t be fixed.
How much does a living trust cost?
Fees vary widely by location and complexity. Expect a trust-based plan to cost noticeably more than a simple will. The real comparison is that cost against likely probate costs and time in your state.
What happens if I have neither?
Your property is distributed under your state’s intestacy laws, and the court appoints an administrator and, if needed, a guardian. See what happens if you die without a will.
How often should I update my plan?
Review it every few years and after major life events: marriage, divorce, birth of a child, death of a beneficiary, a significant change in assets or a move to another state.
When to talk to an estate planning lawyer
An attorney is particularly valuable if you have minor children, own real estate, have a blended family, own a business, have a beneficiary who receives government benefits, or have a large estate. An estate planning lawyer licensed in your state can explain local probate costs and help you set up and fund a plan correctly, which is where most do-it-yourself plans go wrong.
