To make a last will and testament, you write a document that names who inherits your property, appoint an executor to carry out those instructions, sign it while you are at least 18 and of sound mind, and have two witnesses sign in your presence. That is the whole legal skeleton. The work is in the details: choosing the right format for your state, covering the provisions that matter, avoiding the assets a will cannot touch, and signing it in a way that will hold up in probate. Done well, a basic will takes an afternoon and prevents years of court-supervised guessing about what you would have wanted.
Who Can Legally Make One
Nearly every state requires you to be at least 18. You also have to be of sound mind at the moment of signing, which courts define as understanding four things: what property you own, who your close relatives and dependents are, what it means to leave property through a will, and how your document distributes that property. You do not need a flawless memory. Someone with early-stage dementia can execute a valid will during a lucid interval. The question is whether you grasp those four concepts when you sign.
Beyond capacity, the document has to reflect what lawyers call testamentary intent. You created it as your actual distribution plan, not as a draft, a joke, or a letter of wishes. Courts read the language and the circumstances to decide whether you meant it as your final directive.
Choose a Format
Three formats exist, and only one is accepted everywhere.
Witnessed Wills
The standard format, recognized in every state. It must be in writing, signed by you (or by someone else at your direction and in your presence), and signed by at least two witnesses who watched you sign. Most states require the witnesses to sign in your presence, and many require them to sign in each other’s presence as well. If you are unsure which format to use, this is the answer.
Holographic Wills
A holographic will is handwritten by you and signed by you, with no witnesses. Roughly half the states recognize them. Some require the entire document to be in your handwriting; others only require that the material portions, meaning who gets what, be handwritten. Because they lack witnesses, holographic wills face more scrutiny in probate and are easier to challenge. Treat them as a stopgap when you cannot get to an attorney, not a long-term plan.
Electronic Wills
As of 2025, roughly 15 states plus the District of Columbia have enacted electronic will statutes. A few states expressly prohibit them. Requirements vary, but these wills generally need an electronic signature, at least two witnesses (who may participate by video in some jurisdictions), and sometimes a filing with the court system within a set deadline. Confirm your state recognizes the format before relying on it. A will valid as an electronic document in one state may not be accepted in a state that has not adopted similar legislation.
Gather Your Information First
Before drafting, compile a full picture of what you own and who you want to benefit:
- Real estate addresses and how each property is titled (sole ownership, joint tenancy, community property). Use the legal description from the deed, not nicknames. “The lake house” means nothing to a probate judge.
- Bank, brokerage, and retirement accounts with approximate balances.
- Vehicles, jewelry, art, collectibles, and anything else of significant financial or sentimental value.
- Debts: mortgages, car loans, credit cards, and other obligations the executor will have to settle.
- Full legal names and current addresses for everyone you plan to name.
- At least one primary and one alternate candidate for executor and, if applicable, guardian.
Preparation makes the drafting faster and keeps forgotten assets from falling through to intestacy.
What the Document Needs to Say
A will is only as useful as the instructions inside it. Leave out a critical provision and you hand that decision to a probate judge.
Beneficiaries and Specific Gifts
Name every person or organization that should receive something, and describe what they get. Be precise. “My 2022 Honda Accord, VIN ending 4837” beats “my car.” “My residence at 412 Oak Street, Austin, TX” beats “the house.” Use full legal names, not nicknames. Specific dollar amounts and specific items both belong here. Percentages of what remains belong in the residuary clause below.
Executor
Your executor (called a personal representative in many states) files the will with the court, pays debts and taxes, distributes assets, and closes the estate. Pick someone organized and trustworthy, and name a backup in case your first choice cannot serve. Executors are entitled to compensation; the amount is set by state rule unless your will specifies a different fee, in which case the will generally controls.
Guardian for Minor Children
If you have children under 18, your will is the place to name a guardian who will raise them if both parents die. Without a nomination, a court picks someone, and the judge may not pick who you would have picked. Name an alternate as well. Judges almost always defer to a parent’s written choice unless there is a compelling reason not to.
Residuary Clause
The catch-all. It covers everything you did not specifically assign: an account you forgot about, property you acquire after signing, or a gift that fails because the named beneficiary died before you. Without this clause, unassigned property passes under intestacy rules as if you had no will at all for those assets. After naming an executor, most attorneys treat this as the single most important provision in the document.
Survivorship Clause
A survivorship clause requires a beneficiary to outlive you by a set period, commonly 120 hours, in order to inherit. It prevents a situation where you and a beneficiary die in the same accident, your assets briefly pass to that beneficiary’s estate, and then flow to people you never intended to benefit. Many states apply a default 120-hour rule, but writing the clause into your will removes any ambiguity.
Digital Assets
Email accounts, social media, cryptocurrency wallets, cloud storage, and online financial accounts are all digital assets your executor may need to reach. More than 40 states have adopted the Revised Uniform Fiduciary Access to Digital Assets Act, which gives executors the legal authority to manage these accounts. Name someone in the will to handle digital assets, and keep a separate, securely stored list of accounts and credentials for them to use. Without direction, your executor can spend months navigating platform policies just to close an email account.
No-Contest Clause
Sometimes called an in terrorem clause, this provision strips the inheritance from any beneficiary who challenges the will in court and loses. Most states enforce them, though courts tend to read them narrowly. Several states carve out a probable-cause exception that protects a challenger who had a good-faith reason to sue. Florida refuses to enforce no-contest clauses at all. If family conflict is a real possibility, the clause adds deterrence without being bulletproof.
Assets a Will Does Not Control
This is where people make the most expensive mistakes. Several common asset types pass directly to a named beneficiary regardless of what your will says. If your will leaves everything to your daughter but your 401(k) beneficiary form still names your ex-spouse, the ex-spouse gets the retirement account. The will loses that fight every time.
Assets that typically bypass your will:
- Retirement accounts: 401(k)s, IRAs, 403(b)s, and pensions pass to whoever is on the beneficiary designation with the plan administrator.
- Life insurance: proceeds go to the named beneficiary on the policy.
- Payable-on-death bank accounts and transfer-on-death brokerage accounts transfer automatically to the named person.
- Property held in joint tenancy with right of survivorship passes to the surviving co-owner by operation of law.
- Transfer-on-death deeds, allowed in many states, move real estate directly to a named beneficiary outside probate.
Review your beneficiary designations at least as often as you review your will. After a divorce, a new child, or a death in the family, an outdated designation will quietly override anything in the will.
Protections You Cannot Override
Even a perfectly drafted will has limits. Every state has laws designed to stop you from leaving your spouse or children with nothing, and those laws apply no matter what the will says.
Spousal Elective Share
In every state, a surviving spouse can claim a minimum share of the deceased spouse’s estate. The amount runs from roughly one-third to one-half, depending on the state. Some states calculate it against an augmented estate that includes life insurance, joint accounts, and large pre-death gifts, not just probate property. A spouse can waive this right, but only through a valid prenuptial or postnuptial agreement. If you plan to leave your spouse less than the statutory share, talk to an attorney before you sign.
Omitted Children
Most states protect children accidentally left out of a will. A child born after you sign and never added by amendment is treated as a pretermitted heir and may be entitled to the share they would have received had you died without a will. Some states extend this protection to any omitted child, not only those born later. If you genuinely intend to leave a child nothing, say so explicitly. Silence looks like oversight, and courts treat oversight as unintentional.
Sign It Correctly
A will that is never properly signed is just paper. The execution ceremony is where the document becomes binding, and cutting corners here is the fastest way to invalidate an otherwise perfect will.
Witnesses
You sign the will in front of at least two witnesses, and they sign in your presence. Some states also require witnesses to sign in each other’s presence. Use witnesses who are not named as beneficiaries. The Uniform Probate Code, which many states follow, does not automatically invalidate a will signed by an interested witness, but plenty of states will void or reduce any gift to a witness who stands to inherit. Disinterested witnesses eliminate the risk entirely and make the will harder to contest.
Self-Proving Affidavit
A self-proving affidavit is a notarized statement, usually attached at signing, in which you and your witnesses swear under oath that the execution was proper. The payoff comes later: without it, your witnesses may need to appear in probate court to confirm their signatures. With it, the court can admit the will without hunting down witnesses who may have moved or died. Notary fees for this service are modest, with state-set caps ranging from $2 to $25 (some states set no cap). The small cost is worth the hassle it saves your executor.
Where to Keep It
Store the original somewhere secure and accessible. A fireproof home safe or a filing cabinet works, as long as your executor knows exactly where to find it. Some states let you file the original with the probate court for safekeeping during your lifetime.
Be careful with bank safe deposit boxes. When a box holder dies, access is often restricted. In many states, a surviving family member can open the box under bank supervision only to retrieve the will and burial instructions, while everything else stays locked until the court issues an order. Your executor may need a court petition just to read the document that authorizes them to act. Tell your executor and at least one trusted family member where the original is. Keep a copy for yourself, but understand that only the original carries legal weight.
Updating or Revoking Later
A will is not a one-time project. Marriage, divorce, a new child, a significant change in assets, or the death of a named beneficiary are all reasons to revisit the document.
You can update it two ways. A codicil is a formal amendment that changes specific provisions and leaves the rest intact; it must be signed and witnessed with the same formality as the original. For anything beyond a minor tweak, most attorneys recommend drafting an entirely new will that explicitly revokes all prior versions. A clear statement such as “I revoke all prior wills” prevents confusion if multiple documents turn up after your death.
You can also revoke a will by physically destroying it with the intent to revoke: burning, shredding, or tearing it, whether you do it yourself or direct someone else to do it in your presence. Crossing out a line or writing “void” on one page is riskier and may not fully revoke the document under your state’s rules. The cleanest path is always to execute a new will with a revocation clause and then destroy the old one.
What It Costs
For a straightforward will, an attorney typically charges a flat fee of roughly $250 to $1,000. More complex estates (business interests, blended families, trusts, tax planning) run higher, often $5,000 to $15,000 when bundled with other estate planning documents. Online will-preparation services charge significantly less, sometimes under $100, but offer limited customization and no legal advice. Many states also publish free statutory will forms through their probate courts, though those forms are bare-bones and may not cover complex situations.
The cost of not having a will is almost always higher. Probate filing fees, attorney fees for administration, executor compensation, and potential family disputes can consume a meaningful part of an intestate estate. A few hundred dollars spent now prevents thousands in cost and confusion later.
