You can change the executor of your will without an attorney. You have two ways to do it: add a codicil that amends your existing will, or write a new will that revokes the old one. Either is legally valid, provided the document meets your state’s requirements for signing and witnessing. The work isn’t in getting permission. It’s in not making the procedural mistakes that sink DIY wills.
Codicil or New Will
A codicil is a short separate document that amends your existing will. It identifies the original will by date, states which provision is changing, names the new executor, and confirms the rest of the will stands. It has to be signed and witnessed the same way the original was.
A new will replaces the old one entirely. It names your updated executor, restates the rest of your estate plan, and includes a clause revoking all prior wills and codicils.
For most people, writing a new will is the better choice. Codicils made sense when wills were typed on typewriters and revising the whole document meant retyping every page. Now, even a template-based rewrite is quick. And codicils cause real problems. When someone dies with a will plus one or more codicils, the executor and court have to read them together and reconcile any inconsistencies. Even slightly ambiguous language about which provisions the codicil changes can fuel disputes among beneficiaries. Codicils can also create procedural work in probate: if your codicil removes a beneficiary, the court may still require the executor to notify that person, even though they inherit nothing. A single self-contained will avoids all of that.
Executing the Document Correctly
Whichever route you take, the document has to meet your state’s execution requirements or a court can throw it out. The core rules are consistent across most of the country. The document must be in writing. You have to sign it. At least two witnesses have to watch you sign or hear you acknowledge your signature, and then sign themselves.
Witnesses generally have to be “disinterested,” meaning they don’t inherit anything under the will. Using a beneficiary as a witness is one of the fastest ways to invalidate a document. In most states, both witnesses have to be present at the same time when you sign. Some states also allow a will to be acknowledged before a notary as an alternative to traditional witnessing.
You have to be of sound mind when you sign, meaning you understand what you own, who your beneficiaries are, and what the document does. You also can’t be signing under pressure or coercion. These capacity and voluntariness rules apply the same way whether you use an attorney or not.
One boundary worth knowing: about half of U.S. states recognize holographic wills, which are handwritten documents without witnesses. Under the Uniform Probate Code model many states follow, a holographic will is valid if the signature and material portions are in the testator’s own handwriting. It’s legal in those states, but holographic wills are much easier to challenge in court than properly witnessed ones. Treat it as a last resort, not a shortcut.
Add a Self-Proving Affidavit
Attaching a self-proving affidavit is the single most valuable step a DIYer can take. It’s a sworn statement, signed by you and your witnesses in front of a notary, confirming that the document was properly executed. It pre-packages the testimony your witnesses would otherwise have to give in court.
Without one, the probate court may need to track down your witnesses after your death to confirm the will is genuine. If a witness has moved, become incapacitated, or died, proving the will becomes much harder. A self-proving affidavit lets the court accept the will without that testimony and speeds up probate significantly. Most states allow them, and the only cost is the notary fee. Skipping this step is one of the most common avoidable mistakes.
Choosing Your New Executor
Before you finalize anything, confirm the person you’re naming actually qualifies. State laws set the specifics, but the general baseline is that an executor must be a legal adult, a U.S. resident, of sound mind, and free of felony convictions.
Out-of-state executors get extra scrutiny. Depending on the jurisdiction, a nonresident executor might need to post a bond, appoint a local agent to accept legal papers, or serve alongside a co-executor who lives in-state. A few states only allow nonresident executors who are related to you by blood, marriage, or adoption. Check your state’s rules before naming someone who lives elsewhere.
Name a Successor
This is where most DIY wills fall short. People name one executor and stop there. But your chosen executor might predecease you, develop health problems, or decline the job when the time comes. If your will doesn’t name a backup and your executor can’t serve, the probate court appoints an administrator on its own, typically working through a statutory priority list that starts with your surviving spouse and works through close relatives. That court-appointed person may not be who you would have picked.
The fix is one sentence: state that if your first-choice executor is unable or unwilling to serve, a named second person takes over. You can name a third as well. That sentence can spare your family a court proceeding.
Revoking the Old Will
If you write a new will, you need to make sure the old one is clearly revoked. The standard approach is a revocation clause at the beginning of the new will: “I declare this to be my last will and testament and revoke all prior wills and codicils.” That language, combined with a properly executed new will, invalidates everything before it.
Physical destruction adds certainty. Shred or burn the original old will and all copies so no prior version can surface during probate and create confusion about which document controls. If you leave the old original sitting in a drawer, an interested party could argue it should govern, especially if there’s any question about whether the new will was properly executed. Destroying the old document ends that argument.
One nuance to be aware of: if your new will doesn’t dispose of your entire estate and doesn’t contain an explicit revocation clause, a court may treat it as a supplement to the old will rather than a replacement. The two would be read together, with the new document overriding only provisions that directly conflict. Always include the express revocation clause and make sure the new will covers your entire estate plan.
Storing the New Will
A perfectly executed will is worthless if nobody can find it. Store the signed original somewhere secure but accessible, and tell your executor exactly where it is and how to get to it.
A fireproof home safe gives your family immediate access but less protection. A bank safe deposit box is highly secure, but your executor may need a court order to open it after your death. Filing the original with an attorney’s office provides security and a documented chain of custody, but depends on that firm staying in business. Some probate courts accept wills for safekeeping during the testator’s lifetime for a small filing fee.
Keep the original will and the self-proving affidavit together. Tell your executor and at least one other trusted person where the documents are and how to access them. A scanned copy is fine as a backup reference, but probate courts almost universally require the original paper document.
Mistakes to Avoid
Changing an executor is one of the simpler will modifications, which is why it’s a reasonable project to handle yourself. Simple doesn’t mean foolproof. The mistakes that cause the most problems:
- Improper execution. Missing a witness, using a beneficiary as a witness, or having witnesses sign at different times can invalidate the entire document. States are strict about these formalities, and there’s no do-over once you’ve died.
- Vague language. A codicil that says “I want my sister to handle things” without identifying the original will by date, naming the sister in full, and explicitly revoking the prior executor appointment creates the kind of ambiguity that fuels probate litigation.
- Ignoring state-specific rules. Requirements vary more than people expect. Some states need notarization, others have unique witness qualifications, and a few don’t recognize certain forms of codicils at all. Check your state’s probate code before drafting.
- Forgetting contingencies. Naming a new executor without a successor leaves you exposed to the same risk that prompted the change. If the new executor can’t serve either, you’re back to a court-appointed administrator.
- Skipping the self-proving affidavit. Without one, your witnesses may need to appear in court after your death to testify the will was properly signed. Tracking them down years later is a burden your executor doesn’t need.
If the only change you’re making is the executor and the rest of your estate plan stays the same, doing this yourself is realistic, particularly if you write a full new will with a revocation clause instead of trying to amend surgically. If your estate involves complex assets, blended family dynamics, or tax planning, the cost of an attorney is small compared to the cost of a will that doesn’t hold up.
