What Is a Will? The 2026 Guide to How It Really Works
A will directs who inherits your estate after death—but retirement accounts and joint assets bypass it. Here's what a will actually controls in 2026.
What Is a Will?
A will—formally a last will and testament—is a signed legal document that names who inherits your probate estate after death, appoints an executor to carry out those wishes, and can designate guardians for minor children. It takes no legal effect during your lifetime and must pass through probate court before its instructions can be carried out.
Once a testator dies, the executor files the will with the local probate court. The court confirms its validity, oversees payment of outstanding debts and taxes, and authorizes distribution to the named beneficiaries. That process is straightforward when the will is clear and properly executed—and expensive when it is not.
Key takeaways
- A will controls only your probate estate—assets solely in your name without a beneficiary designation or survivorship title.
- Retirement accounts, life insurance, joint-ownership property, and payable-on-death accounts bypass your will entirely, regardless of what the will says.
- Every U.S. state except Pennsylvania requires two adult witnesses; Louisiana also requires a notary public.
- Without a will, your state's intestacy statute—not you—decides who inherits, in an order that can produce results you would never have chosen.
- As of 2025, only about one in four American adults had a will, according to Caring.com's annual Wills and Estate Planning Study.
What Does a Will Actually Control? The Hidden Blind Spot
Here is the most important thing most "what is a will" articles skip: a will controls only your probate estate—property titled solely in your name with no designated beneficiary or survivorship right. For millions of households, that is a smaller fraction of total wealth than people expect.
Beneficiary designations on retirement accounts and life insurance are independent contracts between you and a financial institution. Courts enforce them exactly as written, even when a more recent will instructs otherwise. A beneficiary designation creates a direct contractual obligation between the financial institution and the named beneficiary. A will provision stating "all assets" go equally to your children cannot override an old form naming only one of them.
What a Will Controls vs. What Bypasses It
| Asset type | Will controls it? | How it actually passes |
|---|---|---|
| Bank account — no POD designation | ✅ Yes | Through probate |
| Checking or savings with a POD beneficiary | ❌ No | Directly to named beneficiary |
| IRA, 401(k), 403(b) | ❌ No | Beneficiary designation form |
| Life insurance policy | ❌ No | Beneficiary designation form |
| Jointly held property with survivorship rights | ❌ No | Automatically to the co-owner |
| Revocable living trust assets | ❌ No | Trust terms |
| Brokerage account with a TOD designation | ❌ No | Directly to named beneficiary |
| Real estate titled solely in your name | ✅ Yes | Through probate |
| Personal property (vehicles, furniture, jewelry) | ✅ Yes | Through probate |
| Business interest without a succession plan | ✅ Yes | Through probate |
Worked Example: The $280,000 Mistake
Alex and Jordan married in 2015. Two years earlier, Alex had opened a 401(k) and named Alex's parent as sole beneficiary. After the wedding, Alex updated a will to leave everything to Jordan—but never filed a new beneficiary designation with the plan administrator.
Alex dies in 2026. The 401(k), now worth $280,000, passes directly to Alex's parent. Jordan inherits only the assets titled solely in Alex's name: a car and a bank account totaling $22,000. The will was carefully drafted, properly witnessed, and completely legal. It simply had no power over the asset that mattered most.
This is why a will is essential but incomplete on its own. You must also audit every beneficiary designation and account title separately. For a fuller comparison of how different planning tools interact, see will vs. living trust.
What Are the Types of Wills?
| Will type | Key feature | Witnesses required? |
|---|---|---|
| Attested (witnessed) will | Written, signed, witnessed by two or more adults | Yes — all 50 states |
| Self-proving will | Includes a notarized affidavit so witnesses need not appear in probate | Optional in most states |
| Holographic will | Entirely handwritten and signed by the testator; no witnesses | No — valid in roughly 25 states |
| Pour-over will | Directs any remaining probate assets into a living trust at death | Yes |
| Testamentary trust will | Creates a trust inside the will, effective only at death | Yes |
| Joint will | One document for two people, typically spouses; the survivor cannot amend it after one dies | Yes — generally inadvisable |
A holographic will avoids witnesses but carries real risk of challenge. Louisiana's version—the "olographic testament"—must be entirely written, dated, and signed in the testator's own handwriting, with any corrections also handwritten. Joint wills are usually inadvisable: once one spouse dies, the survivor is typically locked into the original terms, creating serious inflexibility as circumstances change.
How Do You Execute a Will Correctly?
Improper execution is the single most common reason wills fail in probate. A perfectly worded document can be declared invalid for a missing witness signature or a disqualified witness. Follow these steps in order:
- Draft the document. State your full legal name, declare that you are revoking all prior wills, name your beneficiaries with their full legal names, list specific bequests, and identify your executor.
- Name a guardian for minor children. Probate courts almost always honor your choice unless appointment would clearly harm the child—for example, if your designated guardian later becomes incarcerated or incapacitated.
- Sign at the end. Most states require the testator's signature to appear at the document's conclusion, not simply somewhere on the page.
- Have two disinterested adults witness your signature, simultaneously. Both witnesses must watch you sign and then sign the document themselves in your presence and in each other's presence. A witness who is also a beneficiary may forfeit their bequest or, in some states, invalidate the entire will. See will witness requirements for your state's exact rules.
- Add a self-proving affidavit. You, your witnesses, and a notary all sign this separate statement at the same session. It eliminates the need for witnesses to appear in probate court later and is accepted in 49 states and the District of Columbia (Ohio does not recognize it).
- Store the original safely. Only the original will is legally binding in most states. Keep it in a fireproof home safe, a bank safe-deposit box, or your county's surrogate or probate court vault. Tell your executor exactly where it is—52% of adult children do not know where their parents' estate documents are stored, according to data cited by eForms.
- Register it (optional). Some states allow you to file a will for safekeeping with the local probate court before death at no cost or a small filing fee.
If you made a technical error during execution, some states apply the harmless error doctrine from the Uniform Probate Code (UPC, originally promulgated in 1969), which allows a court to admit an improperly executed will if convincing evidence shows the testator intended it as their will. That doctrine is not available in all states and is not a substitute for executing correctly from the start.
On cost: attorney-drafted simple wills range from $300 to $1,000; online services run $10 to $250; handwritten holographic wills can cost nothing in states that accept them.

How Intestacy Laws Work When There Is No Will
If you die without a valid will, you die "intestate." Your state's probate court distributes your estate according to its intestacy statute—not your preferences. Intestacy recognizes only legal relationships: unmarried partners, regardless of how long the relationship lasted, appear nowhere on the inheritance list. Stepchildren you never legally adopted inherit nothing. A favorite charity receives nothing.
The defaults vary significantly by state and can produce outcomes that surprise even careful families—particularly when children from a prior relationship are involved, which reduces a surviving spouse's share in most states.
For a full breakdown of what your state's default plan looks like, see what happens if you die without a will.
Selected State Intestacy Defaults
| State | Surviving spouse, no children | Surviving spouse + children (all shared) | Governing statute |
|---|---|---|---|
| California | Spouse inherits everything | Spouse keeps all community property; separate property split with children | Cal. Prob. Code § 6401 |
| Texas | Spouse inherits everything | Community property to spouse; separate property split between spouse and children | Texas Estates Code Ch. 201 |
| New York | Spouse inherits everything | Spouse gets first $50,000 plus half the remainder; rest to children | N.Y. EPTL |
| Florida | Spouse inherits everything | Spouse inherits everything when all children are shared | Fla. Prob. Code Ch. 732 |
| Maryland | Spouse inherits everything | Spouse gets first $40,000 plus half the remainder; rest to children | Md. Code Est. & Trusts § 3-102 |
Critical note for blended families: If you have children from a prior relationship, every row in this table changes—often substantially reducing your current spouse's share. A will replaces these defaults with your own instructions. A correctly funded living trust does the same and also skips probate court entirely, which matters if you want to know how long your family waits for access to assets.

Common Mistakes to Avoid
- Assuming your will controls your 401(k) or life insurance. It doesn't. Those assets pass by beneficiary designation. The designation form beats the will every time, even if the will was signed more recently.
- Naming a beneficiary as a witness. Most states require witnesses to be "disinterested"—not inheriting under the will. A beneficiary-witness may forfeit their bequest, or the will's validity may be challenged in probate.
- Failing to update after divorce. Some states automatically revoke bequests to a former spouse after divorce—for example, New York under N.Y. EPTL § 5-1.4. That statute does not reach beneficiary designations on retirement accounts and insurance held at financial institutions. You must update both the will and all designation forms. For guidance on amending the document itself, see how to change a will.
- Keeping only a photocopy. Most states require the original will to be filed with probate court. A photocopy alone generally cannot be admitted without a costly "lost will" proceeding.
- Using vague language. "My jewelry to my daughter" creates a dispute if you have two daughters or acquire new jewelry after signing. Use full legal names and describe items specifically.
- Never reviewing it. A will written before a remarriage, before children arrived, before you moved states, or before your financial picture changed materially may distribute your estate in ways you would never choose today.

Frequently Asked Questions
What is a will and what does it do?▾
A will, formally called a last will and testament, is a signed legal document that names who inherits your probate estate after you die, appoints an executor to manage the process, and can designate guardians for minor children. It has no legal effect during your lifetime and must pass through probate court to take effect.
Does a will override a beneficiary designation on a retirement account or life insurance policy?▾
No. Beneficiary designations on IRAs, 401(k)s, life insurance policies, and payable-on-death bank accounts are contracts with financial institutions and bypass probate entirely. Courts enforce the beneficiary form as written, even when it conflicts with the will. Review these designations separately after every major life change.
What makes a will legally valid in the United States?▾
In most U.S. states, a valid will must be in writing, signed by the testator, and witnessed by at least two adults who are not beneficiaries. Louisiana additionally requires a notary public. Pennsylvania uniquely accepts a will signed only by the testator. Electronic wills are now recognized in more than a dozen states.
What happens if you die without a will?▾
Dying without a valid will means dying intestate. State intestacy laws then distribute your probate estate in a fixed order—typically spouse first, then children, then parents and siblings—regardless of your wishes. Unmarried partners, close friends, and charities receive nothing under these default rules unless named on non-probate accounts.
Who should I name as executor of my will?▾
Name someone trustworthy, organized, and ideally located near your state. An executor files the will with probate court, pays outstanding debts and taxes, and distributes assets according to your instructions. A family member, close friend, or professional fiduciary such as a bank trust department can all serve in this role.
Can you write your own will without hiring a lawyer?▾
Yes. Adults with testamentary capacity can draft their own will using online services, state statutory forms, or handwritten formats where permitted. The main risk is improper execution—missing witnesses, unclear language, or a witness who is also a beneficiary—that can invalidate the document or trigger expensive probate disputes.
When should you update your will?▾
Update your will after marriage, divorce, the birth of a child, death of a named beneficiary or executor, a major change in assets, or a move to a new state. Most estate planners recommend reviewing it every three to five years even without major life changes, to confirm the document still complies with current state law.
What assets cannot be controlled by a will?▾
A will cannot control retirement accounts such as IRAs and 401(k)s, life insurance death benefits, payable-on-death bank accounts, transfer-on-death brokerage accounts, jointly owned property with survivorship rights, or assets held in a living trust. These transfer directly to named beneficiaries or co-owners, bypassing both the will and probate.
