Universal Requirements for a Valid Will in the US

Regardless of state, every valid will in the United States must meet these baseline requirements:

• Testamentary capacity: You must be at least 18 years old (exceptions for active military in some states) and of sound mind
• Testamentary intent: The document must clearly be intended as your will
• Signed: You must sign the will (or direct someone to sign on your behalf if you are physically unable)
• Witnesses: Most states require 2 disinterested witnesses who watch you sign
• No undue influence: You must act freely — the will cannot be the result of coercion or manipulation

Note: Requirements are subject to legislative changes. Always verify current requirements for your state before executing your will.

What Is a Holographic Will?

A holographic will is entirely handwritten and signed by the testator — no witnesses required. About 26 states recognize holographic wills, including California, Texas, Virginia, and most southern and western states. States that do NOT recognize them include Florida, New York, Illinois, and Georgia.

While holographic wills are legal in many states, they come with risks:

• More easily contested (harder to prove mental capacity, lack of undue influence)
• Ambiguous handwriting can create disputes
• If you move to a state that doesn't recognize them, the will may be invalid
• Must be entirely in your handwriting — partial holographic wills are often rejected

What Is a Self-Proving Affidavit?

A self-proving affidavit is a notarized statement by the witnesses affirming they saw you sign the will. It's attached to the will and makes probate faster and easier — the court can admit the will without tracking down witnesses years later to testify.

Most online will services generate the self-proving affidavit language automatically. It requires a notary public to notarize at the time of signing.

Step-by-Step: How to Make Your Will Legal in Any State

1. Draft your will using an online service or attorney. Include all required elements: beneficiaries, executor, guardians for minor children (if applicable), and residuary clause.
2. Print the final document — you must sign a physical copy in most states (though some states now allow electronic wills).
3. Gather 2 adult witnesses who are NOT beneficiaries under the will and NOT spouses of beneficiaries. They must watch you sign.
4. Sign the will in front of both witnesses simultaneously (they watch each other sign too, in most states).
5. Have witnesses sign the attestation clause affirming they witnessed your signature.
6. Optional but recommended: Sign a self-proving affidavit before a notary public at the same time.
7. Store the original safely — a fireproof safe, a safe deposit box, or with your attorney. Tell your executor where it is.

Electronic Wills: Which States Allow Them?

A growing number of states now allow fully electronic wills (signed and witnessed online via video). As of 2026, states with electronic will legislation include:

• Arizona, Florida, Indiana, Nevada, Utah, Washington
• Virginia (comprehensive electronic will act)
• Several more states with pending legislation

Even in states that allow e-wills, traditional paper wills remain valid and are generally more straightforward for probate.

What Happens Without a Valid Will?

If you die without a valid will (intestate), your state's intestacy laws determine who receives your assets. These laws follow a rigid formula — typically spouse first, then children, then parents, then siblings. The state's formula may not reflect your wishes at all:

• Unmarried partners receive nothing under intestacy laws
• Stepchildren typically receive nothing unless legally adopted
• Charities you care about receive nothing
• Distant relatives you've never met might inherit before a lifelong friend
• If no relatives can be found, your estate escheats (goes) to the state
