How to Change or Revoke a Will

You can change or revoke your will at any time while you are alive and have the mental capacity to do so. A will is not permanent — in fact, reviewing and updating it periodically is a normal and important part of estate planning. The key is doing it correctly. Crossing things out, writing in the margins, or stapling a note to the original document is not a valid way to change a will in most states. Informal modifications can create confusion, invite legal challenges, and potentially compromise parts of the will entirely.

This guide explains the proper ways to make changes — large or small — and how to revoke a will entirely when the time comes.

When to Review and Update Your Will

Your will should reflect your current wishes, relationships, and assets. Common life events that call for a review include:

• Marriage or divorce (state law may automatically affect your will — see below)
• The birth or adoption of a child
• The death of a named beneficiary, executor, or guardian
• A significant change in your finances or the nature of your assets
• A move to a different state (your will may remain valid, but the new state's probate code will govern administration)
• A change in your relationships — estrangement, reconciliation, or a wish to add or remove someone

Option 1: Execute a Codicil (For Limited Changes)

A codicil is a formal written amendment to an existing will. It allows you to change specific provisions without rewriting the entire document. A codicil might update who serves as your executor, change a specific bequest, or add a new beneficiary for a particular gift.

The critical requirement: a codicil must meet the same legal formalities as the original will. That typically means it must be in writing, signed by you, and witnessed by the required number of witnesses under your state's law — just as if it were a new will. An improperly executed codicil is generally invalid, and informal handwritten additions to a typed will have no legal effect in most states.

Codicils work best for limited, clearly defined changes. When you have accumulated multiple codicils, or when the changes are substantial enough that the relationship between the codicil and the original becomes confusing, executing a new will is usually the cleaner and more legally certain approach.

Option 2: Execute a New Will (Preferred for Significant Changes)

For significant changes — a new family structure, a substantial redistribution of your estate, or changes that affect many provisions at once — the better approach is typically to execute an entirely new will. A properly drafted new will should include a revocation clause near the beginning, stating expressly that it revokes all prior wills and codicils.

A new will with a clear revocation clause:

• Eliminates any ambiguity about which document controls
• Removes the risk of conflicting provisions between the old will and the new one
• Creates a single, self-contained document that is easier for your executor and the probate court to follow

Like any will, the new document must meet your state's formalities — writing, your signature, and proper witnesses — to be valid.

Option 3: Physically Destroy the Will (Revocation by Act)

Most states allow you to revoke a will by physically destroying it — burning, tearing, obliterating, or otherwise canceling it — with the intent to revoke it. Both elements matter: the act of destruction and the intent behind it. Accidentally destroying a will generally does not constitute a revocation.

Important considerations:

• If your attorney or a family member holds a copy, destroying your copy alone may not effectively revoke the will in all states. Some states allow a copy to be admitted to probate; others require evidence that the original was intentionally revoked.
• In some states, asking another person to destroy the will for you — in your presence and at your direction — is also a valid form of revocation.
• Partial destruction (crossing out only your signature, for example) has unpredictable legal effects that vary by state and can generate disputes.

Because the rules governing revocation by physical act vary by state, executing a new will with a revocation clause is generally the more legally certain method — and the one that leaves the clearest paper trail.

What Does Not Work

Some informal attempts to change a will are not legally effective in most states:

• Writing in the margins or crossing out language and substituting new language by hand
• Attaching an unsigned note or letter to the will
• Telling family members or your attorney about your new wishes without a properly executed written document
• Signing a document that does not meet your state's witness and formality requirements

In many states, unauthorized handwritten changes to a typed will can raise questions about the will's integrity, trigger disputes among heirs, or cause a court to question whether the entire document was compromised. If you want to make a change, use a formally executed codicil or a new will.

Revocation by Operation of Law

In some states, certain life events can automatically affect a will — or specific provisions in it — under a doctrine called revocation by operation of law. Common examples include:

• Marriage: In some states, getting married after making a will can affect the will's validity or may entitle the new spouse to a share of the estate as a pretermitted (overlooked) spouse, even if the will predates the marriage.
• Divorce: Many states automatically revoke bequests to a former spouse — and sometimes to the ex-spouse's relatives — when a divorce is finalized, though the rest of the will generally remains intact. The exact effect varies by state.
• Birth of a child after the will was made: Some states have pretermitted heir rules that give a child born or adopted after a will was made certain rights in the estate, even if the child is not mentioned in the will.

These automatic rules vary significantly by state, and they do not always produce the result you would want. The safest approach is to update your will proactively after any major life event rather than relying on automatic statutory rules.

Changing Beneficiary Designations

Many important assets pass entirely outside your will. Life insurance, retirement accounts, payable-on-death (POD) bank accounts, and transfer-on-death (TOD) investment accounts are each controlled by the beneficiary designation on file with the institution — not by your will. If you want to change who receives those assets, you must update the beneficiary designation directly with each institution. Your will cannot override a beneficiary designation, and a codicil to your will has no effect on them either.

What You Can Do

• Do not mark up your existing will. Set aside the urge to cross out language or write notes in the margins. Instead, schedule a proper update using a codicil or a new will.
• Decide whether a codicil or a new will fits your situation. Small, clearly defined changes can often be handled with a codicil. Larger changes — or any situation where you have already made prior codicils — usually call for a new will with a revocation clause.
• Meet your state's formalities. Whatever method you use, it must be in writing, properly signed, and properly witnessed under your state's law. Requirements vary by state.
• Destroy superseded documents. Once you have a valid new will, destroy all prior versions and codicils to prevent confusion about which document controls at probate.
• Update beneficiary designations at the same time. Review life insurance, retirement accounts, and POD/TOD accounts whenever you update your will — they are equally important parts of your estate plan.
• Act before capacity becomes an issue. A will can only be changed while you have the legal capacity to do so. Serious illness can limit or eliminate that window.
