A properly signed will does not expire. Once you execute it under your state’s rules, it stays legally valid from that day until you either revoke it or die, no matter how many years pass in between. A will you signed at 30 works the same way at 90. There is no renewal deadline, no re-signing requirement, and no clock ticking down in the background. What can shorten a will’s usable life is your own action, a later document, or a handful of life events that state law treats as automatic changes.
Valid Until You Revoke It or Die
During your lifetime, a will is a set of instructions sitting in a drawer. It transfers nothing, gives your named executor no authority, and hands beneficiaries no claim to your property. You can change it, tear it up, or ignore it. Only your death activates it.
Even then, the will does not operate on its own. Someone, usually the executor you named, has to file the will and a death certificate with the local probate court. The court reviews the document, confirms it meets your state’s requirements, and formally appoints the executor. Until that step, the executor has no legal power to access accounts, sell property, or distribute anything.
What Keeps an Old Will Enforceable
Because a will can sit unused for decades, its long-term usefulness depends on whether it was properly created in the first place. The core requirements are consistent across most states, though specific details vary.
- Legal age. You generally must be at least 18 to make a will.
- Mental capacity. You need to understand what you own, who your natural heirs are, and how the will distributes your property. This bar is lower than the capacity required to sign a contract. Someone with mild cognitive decline can still have enough awareness to execute a valid will.
- Written and signed. Nearly every state requires the will to be in writing and signed by you. If you physically cannot sign, most states allow someone else to sign at your direction in front of witnesses.
- Witnesses. Most states require two witnesses who watch you sign and then sign the document themselves. Witnesses generally should not be beneficiaries under the will.
A will that meets these requirements when signed remains valid decades later. There is no need to re-sign it, renew it, or have it re-witnessed.
The Self-Proving Affidavit
One way to protect a will’s long-term validity is to attach a self-proving affidavit at signing. It is a notarized statement, signed by you and your witnesses, confirming the will was executed properly. Without one, the probate court may have to track down your witnesses after your death to verify the will is authentic. If you signed 30 years ago, those witnesses may have moved, become unreachable, or died. A self-proving affidavit lets the court accept the will without live witness testimony.
What Happens If You Move
A will created under one state’s law may face scrutiny if you move to a state with different formalities. Most states honor out-of-state wills that were valid where signed, but updating the will after a major move is still good practice.
How You Can End a Will’s Life Early
A will lasts as long as you let it. You have complete power to revoke it during your lifetime, and there are two primary methods.
Signing a New Will
The most common approach is executing a new will. A properly drafted replacement includes language stating that it revokes all prior wills and codicils, so the court will not try to piece together instructions from multiple documents. Even without that explicit language, a new will covering the same ground generally revokes the earlier one through inconsistency; if both cannot be followed, the newer one wins.1Legal Information Institute.

Destroying the Original
You can also revoke a will by physically destroying it, such as burning, tearing, or shredding. The critical element is intent. Spilling coffee on your will or losing it in a house fire does not revoke it. You have to destroy the document with the specific purpose of revoking it.2Legal Information Institute. Revocation of Will by Act In most states, you can direct someone else to destroy the will on your behalf, provided they do it in your presence and at your explicit direction.
Codicils for Small Changes
If you want to keep the will but tweak one part, such as swapping an executor or adjusting a bequest, you can add a codicil. A codicil is a written amendment that modifies specific provisions and leaves the rest intact. It must meet the same formalities as the will itself: written, signed, and witnessed. For major overhauls, drafting a new will is cleaner. Stacking multiple codicils can create confusion and invite challenges.
Life Events That Quietly Rewrite It
Even if you never touch your will again, certain life events can change its effect by operation of law. These automatic adjustments exist because legislatures assumed most people would want their estate plan updated after a major shift in family structure, even if they never got around to the paperwork.
Divorce
In most states, divorce automatically cancels any provisions in your will that benefit your former spouse. Bequests to your ex, appointments naming them as executor, and powers of appointment granted to them are all treated as though your ex predeceased you. The rest of the will stays intact. This approach follows the Uniform Probate Code, which the majority of states have adopted in some form. The cancellation also typically extends to relatives of your former spouse who are no longer related to you after the divorce.
Two nuances matter. A legal separation that does not end the marriage usually does not trigger this automatic revocation. And if a divorce settlement or court order specifically addresses what happens under the will, that agreement controls instead of the default rule.
Marriage
Marriage is trickier. Getting married after signing a will does not automatically revoke the entire document in most states. Instead, your new spouse is typically entitled to a share of your estate as an “omitted spouse,” the same share they would have received if you had died without a will. The reasoning is that you probably would have included them if you had updated the document. This protection disappears if the will itself shows you intentionally left the future spouse out, or if you provided for them through other means like a trust or joint account.
When to Review Even Though It Never Expires
Because a will never lapses on its own, it is easy to forget about. Estate planning attorneys generally recommend reviewing your will at least every five years, even if nothing dramatic has changed. Tax laws shift, relationships evolve, and assets grow or shrink in ways that can make a decades-old will badly out of step with your actual situation.
Beyond that regular check-in, certain events should send you back to your attorney:
- Marriage, divorce, or the birth of a child.
- A beneficiary’s circumstances change, such as a disability, a death, or a shift in your trust in them.
- You move to a different state, where estate laws may treat parts of your plan differently.
- A major change in your assets, like selling a business, receiving a large inheritance, or buying real estate.
- Your executor or agent can no longer serve because they have died, become incapacitated, or fallen out of your life.
Skipping these reviews will not make the will invalid, but it can produce results you never intended. A will leaving everything to a spouse you divorced ten years ago may have its spousal provisions cancelled automatically, while the alternate distribution sends assets somewhere you never planned.
When a Will Effectively Disappears
The “lasts forever” principle has one important limit. If the original signed will cannot be found after your death, most courts apply a legal presumption: they assume you destroyed it on purpose with the intent to revoke it. The presumption is rebuttable, meaning your family can try to prove the will was lost or accidentally destroyed, but that is an uphill fight.
Admitting a photocopy of a lost will to probate is possible in many states, but the bar is high. The person offering the copy generally must prove the original was not revoked and that the copy accurately reflects its contents. That is why storage matters: keep the original in a fireproof safe, a bank safe deposit box, or with your attorney, and tell your executor exactly where to find it.
One Duty That Kicks In Right Away
The fact that a will has no expiration date does not mean there is no time pressure once you die. Whoever has possession of the will is legally required to deliver it to the probate court, and most states set a specific deadline, often within 30 days of learning about the death. An executor who delays or fails to file can be sued by beneficiaries who suffer financial harm from the delay, and someone who deliberately hides a will for personal gain may face criminal liability on top of civil exposure. A will that lasted 40 years still needs to reach the courthouse quickly at the end.
