If you’re a competent adult in the United States, you can write your own will without a lawyer. You need to be at least 18 (a few states allow emancipated minors), you need to understand what you’re doing when you sign, and you need to follow your state’s rules for signing and witnessing. The drafting itself is not complicated for a straightforward estate. What trips people up is the execution: a missing witness, a vague gift, or a beneficiary form that contradicts the will can undo the whole plan in probate.
Who Can Legally Write Their Own Will
Two things qualify you. The first is age, which in nearly every state means 18. The second is “testamentary capacity,” which a court tests with four questions: Did you understand you were creating a document to distribute your property after death? Could you identify what you owned? Did you know who your close family members and loved ones were? And could you put those pieces together into a coherent plan?
Capacity is measured at the moment you sign. Someone with early-stage dementia can have clear days and execute a valid will on one of them. The bar is a basic understanding of the act, the assets, and the people, not perfection.
A will can also be set aside for undue influence, meaning someone in a position of power over you steered the terms for their own benefit. A caretaker who controls your finances or housing and suddenly appears as the main beneficiary is the classic pattern. Courts can strike tainted provisions, and sometimes the entire document, if the result doesn’t reflect what you actually wanted.
Most DIY wills are typed documents signed in front of witnesses, and every state accepts that format. About half the states also recognize a handwritten (holographic) will with no witnesses, but the material provisions have to be in your own handwriting, and the document may not travel well if you move. A witnessed, typed will is the safer default.
What to Put in the Document
Open with a plain statement that this is your last will and that it revokes any earlier versions. That one sentence establishes your intent and prevents a stale draft from resurfacing to compete with it.
After that, the document does three jobs: it says who gets what, who’s in charge, and who raises your children.
Beneficiaries and Specific Gifts
Identify people by full legal name and relationship, not “my sister” or “my oldest.” You can leave specific items to specific people, such as a wedding ring to your daughter or $10,000 to a nephew. For real estate, use the property address. For financial accounts, give enough identifying information that your executor can find them. “My savings” is an invitation to a fight when there are three savings accounts across two banks.
Then write a residuary clause, which assigns everything not specifically mentioned, by percentage, to one or more people. Without one, leftover assets fall into intestacy and get distributed by a state formula built for people who never planned at all.
Executor
Your executor, called a personal representative in many states, is the person who takes the will through probate, gathers assets, pays debts and taxes, and distributes what’s left. Choose someone organized, trustworthy, and willing to deal with paperwork and deadlines. Name an alternate in case your first choice can’t serve. If you leave this blank, a judge chooses for you.
Guardian for Minor Children
If you have children under 18, your will is where you nominate a guardian. A judge still has to approve the appointment based on the child’s best interests, but courts almost always honor the parents’ stated preference. Leave this out and the decision goes entirely to a judge who knows very little about your family.
Debts and Funeral Costs
You can note funeral preferences, but understand the pecking order. State probate law pays funeral and burial costs first, then court and administrative fees, then taxes and medical bills, then other debts like credit cards. Beneficiaries only see what’s left. Your will can’t change that order, but it can tell your executor which assets to sell first to cover what’s owed.
Assets Your Will Won’t Control
This is the step most DIY writers miss. Certain assets pass outside your will no matter what you write. They go to whoever is named on the account or title.
- Life insurance proceeds go to the beneficiary on the policy.
- Retirement accounts, including 401(k)s and IRAs, go to the designated beneficiary on file with the plan.
- Bank accounts with a payable-on-death designation go to the named person.
- Property held in joint tenancy with right of survivorship passes to the surviving co-owner.
- Assets inside a trust are distributed under the trust’s terms.
If your will leaves your IRA to your daughter but the beneficiary form still lists your ex-spouse, your ex-spouse gets the IRA. The beneficiary designation wins every time. Pull every policy, account, and deed, confirm who’s named, and update anything that no longer matches your plan. That review matters as much as the will itself.
Signing and Witnessing
Writing is the easy part. The signing ceremony is where DIY wills most often fail. Nearly every state requires that you sign the will in the presence of at least two witnesses, who then sign it themselves. Some states require your signature at the very end of the document. Signing at the end is the safest practice everywhere.
Use witnesses who are adults and who inherit nothing under the will. Many states that follow the Uniform Probate Code technically allow an “interested” witness without voiding the document, but some older state rules can strip the gift to a witness even when the rest of the will stands. Two disinterested witnesses eliminate the problem.
The witnesses have to see you sign, or hear you acknowledge the signature as yours. They don’t need to read the will. They’re confirming you signed voluntarily and appeared to know what you were doing, not endorsing your choices.
Add a Self-Proving Affidavit
A self-proving affidavit is a short sworn statement, signed by you and your witnesses in front of a notary, that attaches to the will. Almost every state allows one. It lets the probate court accept the will without hunting down your witnesses years later to testify, which matters when witnesses have moved, become unreachable, or died.
The process takes a few minutes. After the will is signed, a notary verifies identities, administers an oath, and seals the affidavit. Notary fees for a standard acknowledgment typically run between $2 and $25 depending on the state, with most charging $10 to $15. Banks and shipping stores often have a notary on staff.
Store It Where Your Executor Can Find It
A valid will nobody can find is the same as no will. Keep the original in a fireproof safe or locked filing cabinet, with your other important documents. A bank safe deposit box can backfire if your executor isn’t an authorized signer, because they may need a court order to open it, which delays probate.
Tell your executor the will exists and where it’s kept. A photocopy or scan is fine for them to read in advance, but the court generally wants the original. In many states, if the original can’t be found, the law presumes you destroyed it on purpose.
Changing or Revoking the Will Later
Marriage, divorce, a new child, a major change in assets, or a falling-out with someone you named are all reasons to revisit the document.
You have two options for changes. A codicil is a separate amendment, signed and witnessed with the same formality as the original. Codicils work for a single small change, like swapping an executor. For anything larger, write a new will instead. Layered codicils create ambiguity about which provisions still control, and ambiguity invites challenges.
To revoke a will, either sign a new one that expressly revokes all prior wills, or physically destroy the original by tearing, shredding, or burning it. Destroy every copy if you go that route so your intent is unmistakable. Some life events also revoke parts of a will by operation of law. In many states, divorce automatically cancels provisions benefiting a former spouse, though the specifics vary.
When to Hire a Lawyer Instead
A DIY will works for a straightforward situation: an uncomplicated family, a modest estate, and clear wishes. Several situations are complex enough that a lawyer pays for themselves many times over.
- Blended families with stepchildren, children from prior relationships, or a current spouse you want to protect while preserving assets for other children. These competing interests are hard to balance with a template.
- Business ownership, where your will has to coordinate with buy-sell agreements, operating agreements, and succession plans. Mistakes here can force a business to dissolve.
- A beneficiary with special needs. Leaving money directly to someone on Medicaid or SSI can disqualify them from benefits. A properly drafted special needs trust protects both.
- Taxable estates. For 2026, the federal estate tax exemption is $15,000,000 per person, a figure set by legislation signed in mid-2025. Estates near or above that threshold benefit from planning strategies that need professional design.1Internal Revenue Service. Whats New – Estate and Gift Tax
- Real estate in another state, which can trigger a separate probate there. An attorney can structure ownership to avoid it.
- Living in one of the nine community property states, where you can generally only leave your half of marital property by will. The other half already belongs to your spouse by law.2Internal Revenue Service. Publication 555 (12/2024), Community Property
If none of that applies, a careful DIY will, properly signed, witnessed, and stored, will do the job it needs to do.
