What Are the Requirements for a Valid Will in Texas?
The rules are simpler than most people expect — but small mistakes can invalidate a will, or make it much more difficult to probate. Here's what Texas law actually requires, in plain English.

A will is one document where getting the details right matters enormously. Texas gives you real flexibility in how you write a will — but it's strict about the signing formalities. Miss one, and a court may refuse the will entirely, sending your estate through Texas intestacy law instead of following your wishes.
Here are the requirements the Texas Estates Code sets for a standard (attested) will.
You must be 18 or older
Or younger if you are legally married or a member of the U.S. armed forces. This is the age of testamentary capacity in Texas.
You must be of sound mind
You need to understand that you're making a will, roughly what you own, and who your natural heirs are. This is judged at the moment you sign — not before or after.
The will must be in writing
Texas recognizes typed (attested) wills and entirely handwritten (holographic) wills. Verbal wills are not valid.
You must sign it
You sign the will yourself, or direct someone to sign for you, in your presence.
Two witnesses must sign
For a typed will, at least two credible witnesses over age 14 must sign in your presence. Choose witnesses who won't inherit under the will — a beneficiary-witness can jeopardize their own gift.
No — a will is valid without notarization. But nearly every properly prepared will includes a self-proving affidavit, and that does get notarized. It's the single most useful add-on to a Texas will, and it's covered next.
The self-proving affidavit: the step that saves your family
A self-proving affidavit is a short sworn statement, signed by you and your witnesses in front of a notary, confirming the will was signed correctly. It gets attached to the will.
Here's why it matters. Without it, when your will goes to probate, the formalities still have to be proven — either through one of the original witnesses, or through two disinterested witnesses who can confirm your signature. Finding those witnesses only gets harder with the passage of time, and it becomes a burden on both the witnesses and your family, sometimes years after the will was signed.
A will with a self-proving affidavit is admitted to probate on the strength of the document itself. No witness hunt. This is standard in an attorney-prepared will — and a frequent gap in DIY and online wills.
Not sure your will meets every requirement?
A quick phone call is the fastest way to find out. No obligation, always at no charge.
What about handwritten wills?
Texas is one of the states that recognizes a holographic will — one written entirely in your own handwriting and signed. It needs no witnesses. That sounds convenient, but handwritten wills are far easier to challenge, often contain ambiguous language, and frequently miss the provisions that make probate smooth. They tend to create the exact dispute a will is supposed to prevent.
What happens if a will doesn't meet the requirements?
If a court finds a will invalid, it's treated as though it never existed. Your property then passes under Texas intestacy law — a fixed statutory formula that decides who inherits, regardless of what you wanted. For blended families, unmarried partners, or anyone with specific wishes, the result can be nothing like your intentions.
That's the whole reason the formalities exist: to prove the will is genuinely yours. Meeting them is straightforward with the right help.
Why have an attorney prepare your will?
You're not required to hire a lawyer to make a will in Texas. But most probate problems trace back to wills that were technically defective, ambiguous, or missing a self-proving affidavit. For a flat fee, an attorney-prepared will is properly executed, self-proved, and built to be admitted to probate without friction — so the people you name actually receive what you intended.
