A 52-year-old father of two dies unexpectedly. He had a will. His family assumed everything was handled. Eighteen months later, his widow is still stuck in probate court, has spent over $14,000 in legal fees, and his adult children from a previous marriage are contesting the distribution of assets. The house could not be sold. The bank accounts were frozen. A document that was supposed to make things easier turned into a source of conflict and delay.
Three blocks away, a woman of similar means dies around the same time. She had a revocable living trust. Her successor trustee distributed assets to her beneficiaries within six weeks, privately, without court involvement, and at minimal cost.
Same goal. Vastly different outcomes. The difference was not about wealth — it was about choosing the right tool.
Most Americans do not have either a will or a trust. According to a 2024 Caring.com survey, only 32% of US adults have a will, and far fewer have a trust. Among those who do have estate planning documents, many have the wrong ones for their situation — or the right ones, poorly drafted. This guide breaks down what each document does, when you need one versus the other, and the mistakes that cost families the most.
Key Takeaways
- A will only takes effect after death and must go through probate — a public, court-supervised process that typically takes 6 to 18 months and costs 3-7% of the estate’s value
- A revocable living trust avoids probate entirely, keeps your affairs private, and allows immediate asset distribution after death — but only for assets that have been properly transferred into the trust
- Every adult needs at least a will, even if they also have a trust, because a will handles anything the trust does not cover (including naming guardians for minor children)
- A basic will costs $200 to $1,000 through an attorney; a revocable living trust runs $1,500 to $5,000 — but the trust often saves multiples of that cost by avoiding probate
- The biggest mistake people make is creating a trust and then never funding it — transferring assets into the trust’s name — which defeats the entire purpose
What a Will Actually Does
A will (technically a “last will and testament”) is a legal document that says who gets your stuff when you die. That is the core of it. But a will does several other critical things:
It names an executor — the person responsible for managing your estate through the probate process. This includes gathering your assets, paying your debts and taxes, and distributing what remains to your beneficiaries. Choose someone organized, trustworthy, and willing to deal with paperwork and potentially difficult family dynamics.
It names guardians for your minor children. This is the one thing a trust cannot do. If you have children under 18, a will is the only document where you can express your preference for who should raise them if both parents die. Without this designation, a court decides — and the court’s choice may not be yours.
It specifies who gets what. You can leave specific items to specific people, divide assets by percentage, create conditional gifts (for example, a grandchild receives money only upon reaching age 25), and designate backup beneficiaries if your primary choices predecease you.
It can disinherit people. In most states, you cannot completely disinherit a surviving spouse — they have a statutory right to a minimum share (called the “elective share,” typically one-third of the estate). But you can disinherit children, siblings, and anyone else, as long as you do so explicitly. Simply omitting someone from the will is not enough in many states and can actually create ambiguity. Name them and state they are intentionally excluded.
Requirements for a Valid Will
The requirements vary by state, but most states require:
- The person making the will (the “testator”) must be at least 18 years old and of sound mind
- The will must be in writing (typed or printed — only about half the states accept handwritten “holographic” wills)
- The testator must sign the will
- Two witnesses must sign the will (Vermont requires three)
- The witnesses should be “disinterested,” meaning they do not stand to inherit under the will
Many states also accept a “self-proving affidavit” — a notarized statement attached to the will that eliminates the need for witnesses to testify in court during probate. Getting your will notarized does not make it valid on its own, but the self-proving affidavit streamlines the probate process significantly.
The Probate Problem
Here is the catch with wills: they must go through probate. Probate is the court-supervised process of validating the will, paying debts, and distributing assets. In theory, it protects beneficiaries and creditors. In practice, it is slow, expensive, and public.
Probate timelines vary by state and complexity. Simple estates may clear probate in 4 to 6 months. Estates with real property in multiple states, contested claims, or complex assets can take 2 years or more. Probate fees — including court costs, executor fees, attorney fees, and appraisal costs — typically consume 3-7% of the estate’s gross value. On a $500,000 estate, that is $15,000 to $35,000 that goes to process rather than to your family.
Probate is also a public proceeding. The will, the inventory of assets, and the list of beneficiaries all become public record. Anyone can look up what you owned and who received it. Celebrities and public figures get their estates picked through by the press, but even ordinary families may not want their financial details available to anyone who visits the courthouse.
What a Trust Actually Does
A trust is a legal arrangement where one person (the “grantor” or “settlor”) transfers assets to a separate legal entity (the “trust”), managed by a person or institution (the “trustee”), for the benefit of designated people (the “beneficiaries”).
The most common estate planning trust is the revocable living trust. Here is how it works in practical terms:
You create the trust document. You name yourself as the initial trustee (meaning you still control everything). You name a successor trustee who takes over when you die or become incapacitated. You name the beneficiaries — the people who will receive the trust assets.
Then — and this is the critical step most people skip — you fund the trust by transferring assets into it. Your house deed is changed from “Jane Smith” to “Jane Smith, Trustee of the Jane Smith Revocable Living Trust dated March 15, 2026.” Your bank accounts, investment accounts, and other titled assets are similarly retitled.
During your lifetime, nothing changes from a practical standpoint. You still control all the assets. You can buy, sell, spend, and modify the trust at any time. The trust uses your Social Security number for tax purposes — there is no separate tax return. You can revoke the whole thing if you change your mind.
When you die, the successor trustee steps in and distributes assets according to the trust’s terms. No probate. No court. No public record. No waiting 6 to 18 months. The successor trustee can often begin distributing assets within weeks.
Types of Trusts
Revocable living trusts are the workhorse of estate planning, but other types serve specific purposes:
Irrevocable trusts cannot be modified or revoked once created. Why would anyone want that? Because assets in an irrevocable trust are no longer considered yours for estate tax purposes, creditor protection, and Medicaid eligibility. If your estate exceeds the federal estate tax exemption ($13.99 million per individual in 2025, though this is set to drop to roughly $7 million in 2026 unless Congress acts), an irrevocable trust can shelter assets from the 40% estate tax.
Special needs trusts hold assets for a disabled beneficiary without disqualifying them from government benefits like Supplemental Security Income (SSI) and Medicaid. A direct inheritance could make someone ineligible for benefits worth far more than the inheritance itself.
Spendthrift trusts protect beneficiaries from their own poor financial decisions (and from creditors). The trustee controls distributions, so a beneficiary with a gambling problem or a bankruptcy cannot blow through the inheritance or have it seized.
Testamentary trusts are created within a will and only come into existence after death. They go through probate (because they are part of the will) but can be useful for creating structured distributions — for example, holding assets for minor children until they reach a specified age.
Will vs. Trust: The Direct Comparison
The question is not really “will or trust” — it is “will alone, or will plus trust.” Nearly everyone who has a trust also needs a “pour-over will” that catches any assets not transferred into the trust during your lifetime and directs them into the trust at death. Those assets still go through probate, but the pour-over will ensures everything ends up in the same plan.
Probate avoidance. A trust avoids probate for all properly funded assets. A will guarantees probate. If you own real property in more than one state, a will means your family goes through probate in every state where you own property (called “ancillary probate”). A trust avoids this entirely.
Cost. A basic will costs $200 to $1,000 through an attorney. A revocable living trust costs $1,500 to $5,000 upfront, plus the time and effort to fund it. But probate costs on even a modest estate typically exceed the cost of creating a trust. The trust costs more now and saves more later.
Privacy. Trusts are private. Wills are public. Period.
Incapacity planning. If you become mentally incapacitated, a trust allows your successor trustee to immediately step in and manage your assets without court involvement. A will does nothing during your lifetime — if you become incapacitated with only a will, your family may need to pursue a conservatorship or guardianship through the courts, a process that is expensive, slow, and demeaning. A durable power of attorney can help with incapacity planning alongside a trust, but the trust provides more comprehensive asset management.
Speed of distribution. Trust assets can be distributed in weeks. Probated assets take months to years.
Contesting. Both wills and trusts can be contested, but trusts are harder to challenge because there is no automatic court proceeding where objections can be raised. A contestant must affirmatively file a lawsuit, which raises the bar.
Who Needs What
A will alone is probably sufficient if:
- You are young and healthy with minimal assets
- You have no real estate or your real estate is in one state
- Your estate is straightforward (everything to spouse, then equally to children)
- You do not have beneficiaries with special needs
- Your total assets (excluding retirement accounts with named beneficiaries) are under $100,000
You should seriously consider a trust if:
- You own real property, especially in more than one state
- You have minor children (the trust can hold and manage their inheritance until they are mature enough to handle it)
- You have a blended family (children from prior relationships)
- Your total estate exceeds $100,000
- You want to avoid probate (cost, time, and privacy concerns)
- You have beneficiaries who should not receive a lump sum (minors, people with addiction issues, people with special needs)
- You want seamless management if you become incapacitated
The Funding Mistake That Ruins Everything
The most common and costly trust mistake is creating the document and then failing to fund it. An unfunded trust is a decorative piece of paper. If you create a revocable living trust but never retitle your house, bank accounts, and investment accounts into the trust’s name, those assets go through probate anyway — defeating the entire purpose.
Funding a trust requires:
- Real estate — A new deed transferring the property to the trust. Check with your mortgage lender first; most mortgages have “due on sale” clauses, but federal law (the Garn-St. Germain Act) generally prevents lenders from calling a loan due when property is transferred to a revocable trust for the benefit of the borrower.
- Bank and investment accounts — Contact each financial institution to retitle accounts in the trust’s name or name the trust as the beneficiary.
- Business interests — LLC membership interests, partnership interests, and closely held stock should be transferred to the trust per the operating agreement or bylaws.
- Vehicles — Some states allow you to transfer vehicle titles to a trust; others do not. In many cases, vehicles are more practically handled through the pour-over will or transfer-on-death registration.
- Personal property — Furniture, jewelry, art, and other items without titles can be transferred by a written assignment of personal property to the trust.
Important exceptions: Do not transfer retirement accounts (IRAs, 401(k)s) into a trust during your lifetime. Doing so triggers a taxable distribution of the entire account. Instead, name the trust as the beneficiary of the retirement account if needed (though naming individuals directly is often better for tax purposes). Life insurance proceeds similarly pass by beneficiary designation, not by trust ownership (though an irrevocable life insurance trust can be useful for estate tax planning).
Assets That Skip Both Wills and Trusts
Several types of assets pass outside of both wills and trusts, directly to named beneficiaries:
- Life insurance proceeds
- Retirement accounts (IRA, 401(k), 403(b), pension)
- Payable-on-death (POD) bank accounts
- Transfer-on-death (TOD) brokerage accounts
- Transfer-on-death (TOD) real estate deeds (available in about 30 states)
- Joint accounts with right of survivorship
These designations override your will. If your will says your daughter gets everything but your life insurance still names your ex-spouse as beneficiary, the ex-spouse gets the insurance money. Reviewing and updating beneficiary designations is just as important as updating your will or trust — maybe more so, since retirement accounts and life insurance often represent the largest portion of a person’s wealth.
When to Update Your Estate Plan
Do not create your will or trust and then forget about it. Review your estate plan whenever:
- You marry or divorce
- A child or grandchild is born
- A beneficiary or executor/trustee dies
- You acquire or sell significant assets (especially real property)
- You move to a different state
- Tax laws change significantly
- Your wishes change
At minimum, review the documents every 3 to 5 years even if nothing has obviously changed. Financial situations shift, relationships evolve, and laws change in ways that can affect your plan.
If you are going through a divorce, understand that many states automatically revoke any provisions in a will that benefit a former spouse once the divorce is final. But this varies by state and does not apply to trusts, beneficiary designations, or powers of attorney. Do not rely on automatic revocation — update everything explicitly.
Frequently Asked Questions
Do I need both a will and a trust?
If you have a trust, yes — you still need a will. Specifically, you need a “pour-over will” that catches any assets not titled in the trust’s name at death and directs them into the trust. The pour-over will also names guardians for minor children, which a trust cannot do. Think of the trust as the main vehicle and the will as the safety net.
Can I write my own will without a lawyer?
Technically, yes. Online services like LegalZoom and Nolo offer will templates for $50 to $200. For very simple situations — single person, no children, minimal assets — these can be adequate. But DIY wills are a leading source of estate litigation because of ambiguous language, missing provisions, and failure to comply with state-specific formalities. The cost of an attorney-drafted will ($200-$1,000) is trivial compared to the cost of probate litigation ($10,000+). For trusts, professional drafting is effectively essential.
How much does probate actually cost?
Probate costs include court filing fees ($50-$500), executor compensation (typically 1-5% of the estate value), attorney fees (either hourly or a percentage of the estate), appraisal fees, and accounting fees. All in, expect 3-7% of the gross estate value. California and other states that set attorney fees by statute can be particularly expensive — a $1 million estate in California generates about $23,000 in statutory attorney fees and the same in executor fees, totaling $46,000 before court costs.
Does a trust protect my assets from creditors or lawsuits?
A revocable living trust provides zero creditor protection during your lifetime because you still control the assets. Irrevocable trusts can provide significant creditor protection because you no longer own the assets. However, transfers to an irrevocable trust made to avoid existing creditors can be voided as fraudulent transfers. Asset protection planning must be done before a claim arises, not after you are sued.
What happens if I die without a will or trust?
Your assets pass according to your state’s “intestacy” laws. Every state has a default distribution scheme — typically spouse first, then children, then parents, then siblings. An unmarried partner gets nothing. A close friend gets nothing. A charity you care about gets nothing. The court appoints an administrator (who may not be the person you would have chosen), and everything goes through probate. Dying intestate is functionally letting the state legislature write your will for you.
