A last will and testament lasts forever once it is signed correctly, but it only stays legally valid until you revoke it, destroy it, or replace it with a newer will. In most states, a will never “expires” on a calendar date, yet the window to file it with a probate court after death is tight, and a stale will can fail in ways the writer never planned for.
The governing rules come from state probate codes, the Uniform Probate Code adopted in part by 18 states, the ancient Statute of Frauds that still shapes signing rules, and judicial precedent like Estate of Duke from the California Supreme Court. When a will is ignored, lost, or filed too late, the probate court may apply the intestate succession rules of the decedent’s state, and the family loses control over who inherits.
Roughly 46% of American adults have a will, according to Gallup polling, and of those, a large share have not updated it in over five years. That gap between having a will and having a current will is where most inheritance fights begin.

The Core Answer: Wills Do Not Expire, But They Can Fail
A last will and testament has no built-in expiration date under any U.S. state law. Once you sign it with the formalities your state requires, it remains your valid will until one of three events happens. You revoke it in writing, you physically destroy it with the intent to revoke, or you sign a new will that supersedes the old one, as codified in UPC § 2-507.
The plain-English meaning is simple. A will you signed in 1985 is still your will in 2026 if you never touched it again. The consequence of that durability cuts both ways. A will drafted before your second marriage, before the birth of your children, or before a state law change may still control your estate even though it no longer reflects your wishes.
A real-world example makes the risk concrete. Maria Alvarez signed a will in 1998 leaving everything to her then-husband Carlos. They divorced in 2010, and Maria never updated the will. When Maria died in 2025, the probate court in Arizona applied ARS § 14-2804, which automatically revokes gifts to an ex-spouse, and her estate passed to her residuary beneficiary instead. The common misconception is that divorce wipes out the entire will. It only wipes out the provisions benefiting the ex-spouse in most states, and the rest of the document still controls.
Validity Versus Enforceability
A will can be valid on paper yet unenforceable in court. Validity means the document met your state’s signing rules at the moment you signed it, usually two witnesses and your signature under UPC § 2-502. Enforceability means the probate court will accept the will, admit it, and follow its instructions.
A will loses enforceability when the original cannot be found, when witnesses cannot be located to testify, or when the filing deadline in the state has passed. The consequence of an unenforceable will is identical to having no will at all. The estate passes under intestate succession, which rarely matches what the decedent wanted.
James Whitfield of Ohio signed a valid will in 1972. His family found only a photocopy after his death in 2024. Under Ohio Rev. Code § 2107.26, a lost will can still be admitted, but the proponents must prove its contents and that James did not revoke it. James’s family won after a two-year fight, but the legal fees consumed 18% of the estate.
The Three Revocation Triggers
Revocation by writing requires a signed document, either a new will or a codicil, that expressly revokes the prior will. Revocation by physical act requires tearing, burning, or obliterating the will with intent to revoke, witnessed or later proven. Revocation by operation of law happens automatically in most states upon divorce, annulment, or in a few states, marriage.
The consequence of a botched revocation is a court battle over which document controls. The common misconception is that crossing out a line in the old will changes only that line. In many states, partial revocation by physical act either voids the whole will or voids nothing, depending on the statute, as the California court wrestled with in Estate of Duke.
How State Probate Deadlines Really Control “How Long”
The most practical “how long” question is not how long the will lasts, but how long the family has to file it with the probate court. These deadlines vary wildly by state, and missing them can turn a valid will into wastepaper. Federal law does not set a probate deadline because probate is a state matter.
The Uniform Probate Code § 3-108 sets a three-year outer limit on opening probate. States that adopted the UPC, including Colorado, Minnesota, and Alaska, follow that rule. States that did not adopt the UPC set their own deadlines, and some are brutally short.
Texas gives four years under Texas Estates Code § 256.003. Florida has no strict deadline for admitting the will but penalizes delay heavily under Fla. Stat. § 732.901, which requires the custodian to deposit the will within ten days of learning of the death. New York has no strict deadline but practical problems mount after a few years.
| State | Deadline to File Will After Death |
|---|---|
| Texas Tex. Est. Code § 256.003 | 4 years |
| Florida Fla. Stat. § 732.901 | 10 days to deposit |
| California Cal. Prob. Code § 8200 | 30 days to deliver |
| New York SCPA § 1401 | No fixed limit |
| UPC States UPC § 3-108 | 3 years |
Why These Deadlines Exist
Probate deadlines exist to give creditors, heirs, and taxing authorities finality. Without a cutoff, an estate could remain open for decades, blocking real estate transfers and freezing bank accounts. The consequence of missing the deadline in a strict state like Texas is that the will cannot be admitted as a muniment of title, and the estate passes by intestacy.
The common misconception is that the family can “just file whenever.” In Texas, filing on day 1,461 after death bars the will unless the filer proves they were not in default, a heavy burden under In re Estate of Perez. The lesson is to file quickly and ask questions later.
The Ten-Day Custodian Rule
Florida, California, and several other states require any person holding a will to deliver it to the court or the executor within a short window, often 10 to 30 days after learning of the death. Under Cal. Prob. Code § 8200, a custodian who fails to deliver the will within 30 days is liable for all damages caused by the delay.
The consequence of hiding or sitting on a will is personal liability, and in extreme cases, criminal charges for concealment. Robert Chen, who kept his late father’s will in a safe for two years in Los Angeles, was sued by his sister and forced to pay $47,000 in damages plus legal fees. The misconception that “the will is family business” collapses the moment the court issues a subpoena.
Life Events That Quietly Rewrite Your Will
State law automatically changes or cancels parts of a will when certain life events happen, even if you never touch the document. These rules exist because legislatures presume the deceased would have wanted the change. The consequence is that your old will may not say what you think it says today.
Marriage After Signing
In a handful of states, marriage after signing a will grants the new spouse an “omitted spouse” share, even if the will names someone else. Under Cal. Prob. Code § 21610, the new spouse takes a statutory share unless the will expressly contemplated the marriage. The plain meaning is that your pre-marriage will cannot cut out your new husband or wife without magic words.
The consequence is a forced reshuffle of the estate, which can disinherit the children from a prior marriage. The common misconception is that a prenuptial agreement solves this. It helps, but the will itself still needs updating. Linda Park of San Diego married her second husband in 2019 without updating her 2005 will. When she died in 2025, her husband claimed and received a statutory one-third share, reducing the gift to her two adult children.
Divorce After Signing
Divorce automatically revokes gifts and fiduciary appointments to the ex-spouse in most states. Under UPC § 2-804, divorce treats the ex-spouse as predeceased for will purposes. The consequence is that the rest of the will remains intact, and the gift passes to the contingent beneficiary.
The U.S. Supreme Court in Egelhoff v. Egelhoff confirmed that federal ERISA law preempts state divorce-revocation statutes for retirement plans. The misconception is that divorce fixes your estate plan automatically. It partially revokes the will but does nothing to 401(k) beneficiary forms, which require a separate update with the plan administrator.
Birth or Adoption of a Child
Most states grant a “pretermitted child” share to a child born or adopted after the will was signed, unless the will expressly disinherits unborn children. Under Fla. Stat. § 732.302, the omitted child receives what they would have received in intestacy.
The consequence is that a new child can claim a full intestate share, which may upend carefully planned gifts to older children. Daniel Okoye, a Miami father who signed his will in 2010 before his youngest daughter was born in 2015, learned too late that his will failed to mention her. When he died in 2024, a Florida court awarded her an equal share with her siblings under the pretermitted child statute.
Three Real Scenarios and Their Legal Fallout
| Scenario | Legal Fallout |
|---|---|
| You sign a will in 2000, divorce in 2015, never update, die in 2026 | Gifts to ex-spouse void under UPC § 2-804; contingent beneficiaries inherit |
| You sign a will in 2010, have a child in 2018, never update, die in 2026 | Child claims pretermitted share under Fla. Stat. § 732.302 |
| You sign a will in 1990, misplace the original, die in 2026 | Family must prove lost-will contents under Ohio Rev. Code § 2107.26; may fail |
Holographic, Electronic, and Self-Proving Wills
Not every will is a typed, witnessed document. The form of the will affects how long it lasts in practical terms because some forms are harder to prove in court years later. The governing rules come from state probate codes and, for digital wills, newer statutes like the Uniform Electronic Wills Act.
Holographic Wills
A holographic will is handwritten and signed by the testator, often without witnesses. About 25 states, including California, Texas, and Virginia, recognize them under statutes like Cal. Prob. Code § 6111. The consequence is that a scribbled note on a napkin can be a valid will if the material terms are in the testator’s handwriting.
The common misconception is that holographic wills are always second-class documents. Courts admit them regularly, but proving the handwriting decades later is a nightmare. Aretha Franklin’s 2014 handwritten will, found in her couch cushions, was admitted by a Michigan jury in 2023 after a bruising family fight.
Electronic and Online Wills
Nevada became the first state to authorize electronic wills in 2001 under Nev. Rev. Stat. § 133.085. Florida, Arizona, Utah, and others have since followed, often under the Uniform Electronic Wills Act. The consequence is that a will signed on a computer with remote witnesses can be fully valid in those states and nowhere else.
The misconception is that a PDF emailed to a lawyer counts as an e-will. It does not unless the state’s e-will statute is followed precisely, including audio-video witnessing and a qualified custodian. Mark Reyes, who signed a DocuSign “will” in Oregon in 2023, left his heirs with nothing because Oregon does not recognize e-wills.
Self-Proving Affidavits
A self-proving affidavit is a notarized statement by the testator and witnesses that the will was signed properly. Under Tex. Est. Code § 251.101, a self-proving will is admitted without the witnesses appearing in court. The consequence is a faster, cheaper probate 40 years later when the witnesses are dead or missing.
The common misconception is that notarization alone makes a will self-proving. It does not. The affidavit must use the exact statutory language and be sworn before a notary in addition to the witness signatures.
How Long Probate Itself Takes
Separate from how long the will lasts, probate itself has a timeline. The median probate case in the United States takes between 6 and 12 months, according to the American Bar Association. Complex estates can take two to three years or longer.
The governing framework is each state’s probate code, plus federal tax rules under IRC § 6018 that require a federal estate tax return within nine months if the estate exceeds the 2026 federal exemption of $13.99 million per individual. The consequence of a drawn-out probate is frozen assets, unpaid bills, and rising legal fees.
Small Estate Shortcuts
Most states allow small estates, typically under $50,000 to $184,500 depending on state, to skip formal probate through a small estate affidavit. Under California’s rule, estates under $184,500 (2022 threshold, adjusted periodically) can use a simplified transfer. The consequence is that the family avoids months of court supervision.
The misconception is that “small” is the same everywhere. Texas sets $75,000. New York sets $50,000. The threshold, the required waiting period, and the forms vary.
Formal Probate Timeline
Formal probate moves through petition, notice to creditors, inventory, creditor claim period, accounting, and distribution. The creditor claim period alone runs four months in California under Cal. Prob. Code § 9100 and six months in many other states. The consequence is that even the fastest uncontested probate takes at least four to six months.
When Should You Actually Update Your Will
Estate planning attorneys generally advise a full review every three to five years or after any major life event. The American Bar Association publishes guidance that mirrors this advice. The consequence of skipping reviews is that your will may be technically valid but practically wrong.
Trigger events include marriage, divorce, birth or adoption of a child, death of a beneficiary or executor, a move to a new state, a large change in assets, a change in federal or state estate tax law, and the sale of a specifically bequeathed asset. Sandra Liu of Seattle sold the family cabin in 2022, but her will still left it to her niece. When Sandra died in 2025, the specific gift was adeemed and the niece received nothing, a rule called ademption by extinction.
Moving to a New State
Your will remains valid in a new state if it was valid where signed, under the full faith and credit clause and most state probate codes. The consequence is that you do not need to redo your will the day you move. The catch is that community property states (California, Texas, Arizona, and six others) handle marital assets differently from common law states.
The misconception is that moving invalidates the will. It rarely does, but community property rules may override parts of it.
Changes in Federal Estate Tax Law
The federal estate tax exemption is scheduled to sunset at the end of 2025 under current law, which was extended and modified by subsequent legislation. The 2026 exemption figure sits at $13.99 million per person. The consequence of not updating a formula-clause will is that an outdated tax plan may send too much or too little to a bypass trust.
Mistakes to Avoid
A valid will can still fail when the testator makes these common errors. Each mistake has a direct negative consequence that flips the estate plan.
- Using a photocopy instead of the original will — many states presume a missing original was revoked, as in In re Estate of Travers
- Failing to name a contingent beneficiary — the gift lapses and the asset falls into the residue
- Forgetting to update after divorce — non-probate assets like 401(k)s still go to the ex under Egelhoff
- Signing without the correct number of witnesses — the entire will is void under UPC § 2-502
- Leaving the will in a safe deposit box no one can access — banks often require a court order to open it
- Naming a minor as outright beneficiary — a guardian of the estate must be appointed, costing thousands
- Using vague language like “my stuff” or “my jewelry” — courts strike ambiguous gifts for uncertainty
- Not coordinating the will with a trust — assets titled in the trust override the will entirely
- Ignoring digital assets — without RUFADAA language, the executor cannot access accounts
Do’s and Don’ts
Do’s:
- Do sign your will with the number of witnesses your state requires, because missing a witness voids the whole document
- Do add a self-proving affidavit to save your heirs from hunting down witnesses decades later
- Do store the original will with a trusted attorney or the probate court’s will deposit, because lost originals are presumed revoked
- Do review your will every three to five years, because life events quietly change what it says
- Do coordinate beneficiary designations on life insurance and retirement accounts with your will, because those forms control regardless of the will
Don’ts:
- Don’t write on or staple the original will after signing, because courts treat alterations as attempted revocation
- Don’t rely on oral promises to override the will, because the Statute of Frauds bars them
- Don’t name your estate as beneficiary of a retirement account, because you lose decades of tax deferral
- Don’t use generic online forms for complex blended families, because pretermitted heir statutes can override them
- Don’t forget to revoke prior wills expressly, because two inconsistent wills trigger expensive litigation
Pros and Cons of Keeping an Old Will
Pros:
- Preserves the legal status quo if your wishes have not changed, avoiding new signing ceremonies
- Locks in favorable tax treatment under the law in force when signed in some rare cases
- Maintains continuity of named executors and guardians who you still trust
- Avoids attorney fees that can run $300 to $1,200 per full revision
- Keeps your estate plan private if the old will is in a safe place
Cons:
- May contain revoked or void gifts that confuse heirs
- May name dead executors, forcing the court to appoint a stranger
- May fail to address assets acquired after signing, especially real estate
- May miss new legal tools like digital asset clauses under RUFADAA
- May use outdated tax formulas that over- or under-fund bypass trusts
Key Entities in the Lifespan of a Will
The testator is the person who signs the will. The executor (called personal representative in UPC states) carries out the will after death. Witnesses attest to the signing and may be called to testify in probate court.
The probate court admits the will, supervises the executor, and resolves disputes. The Internal Revenue Service collects federal estate tax if the estate exceeds the exemption. State legislatures set the probate code, and state supreme courts interpret it through cases like Estate of Duke, which reshaped California’s rule on extrinsic evidence to correct mistakes in a will.
Recap of Key Court Rulings
Estate of Duke (Cal. 2015) overturned a century-old rule and now allows California courts to reform a will to correct a mistake when clear and convincing evidence shows the testator’s true intent. The consequence is that a typo in a California will is no longer automatically fatal.
Egelhoff v. Egelhoff (U.S. 2001) held that ERISA preempts state divorce-revocation statutes for retirement plan benefits. The consequence is that a divorced spouse still named on a 401(k) beneficiary form will receive the money, even if state law would revoke the gift in a will.
In re Estate of Franklin (Mich. 2023) admitted Aretha Franklin’s 2014 handwritten couch-cushion will as a valid holographic document. The consequence was that her earlier 2010 will was displaced and her four sons’ inheritance split changed.
FAQs
Does a last will and testament expire after a certain number of years?
No. A properly signed will has no expiration date in any U.S. state. It remains valid until you revoke it, destroy it with intent, or replace it with a newer will under UPC § 2-507.
Does getting married automatically cancel my old will?
No. Marriage alone does not revoke a will in most states, but it may give your new spouse an omitted-spouse share under statutes like Cal. Prob. Code § 21610 unless the will expressly handles the marriage.
Does divorce automatically revoke my entire will?
No. Divorce only revokes the provisions favoring your ex-spouse in most states under UPC § 2-804. The rest of the will, including gifts to children and charities, remains fully effective.
Is a handwritten will legal?
Yes. About 25 states, including California under Cal. Prob. Code § 6111, recognize holographic wills if the signature and material terms are in the testator’s own handwriting, even without witnesses.
Does my will from another state still work if I move?
Yes. A will valid where signed is generally valid nationwide, but community property states may apply different rules to marital assets, so a review by a local attorney is smart.
Can I file a will years after someone dies?
Yes, in many states, but deadlines vary. Texas allows four years under Tex. Est. Code § 256.003. UPC states cap it at three years. Missing the deadline usually forces intestate succession.
Does a photocopy of a will work in probate?
No, not easily. Most states presume the missing original was revoked, and the family must prove by clear evidence that the testator did not destroy it, as required under Ohio Rev. Code § 2107.26.
Does a will override a 401(k) beneficiary form?
No. Federal ERISA law controls retirement plans, and the beneficiary form wins, as the Supreme Court confirmed in Egelhoff v. Egelhoff. Update both documents after every major life event.
Is an online or electronic will valid in my state?
Yes, but only in states that passed an e-will statute such as Nevada, Florida, Arizona, and Utah under frameworks like the Uniform Electronic Wills Act. Elsewhere, an e-will is void.
Should I update my will after buying a house?
Yes. A new major asset can fall outside your specific gifts and land awkwardly in the residue. Update your will or use a transfer-on-death deed to keep control.
Does the probate court keep my will on file while I am alive?
Yes, in many states. California, Ohio, and others let you deposit your will with the probate court for safekeeping, eliminating the lost-will risk and keeping the original secure until death.
Is a will automatically enforced when I die?
No. Someone must file the will with the probate court, open an estate, and ask the judge to admit it. Without that filing, the will does nothing and state intestacy rules take over.
