What Constitutes a Valid Will?

What constitutes a valid will may seem like an easy question, but it’s often more complicated than people realize. Many families feel relieved just to find a will after someone passes away. However, simply finding it doesn’t mean it’s legal—or that the court will accept it.

Sadly, families sometimes learn too late that the document they’re holding doesn’t meet their state’s legal standards. This can create delays, disputes, and even result in the estate being settled according to state laws—not the loved one’s wishes.

Before you move forward with anything else, you need to confirm what constitutes a valid will in your state.

How to Confirm If a Will Is Valid

What constitutes a valid will starts with locating the document. Families often struggle to find it. Wills can be hidden in homes, stored at law offices, or kept in safe deposit boxes. You should also check your probate court’s website for registered wills.

Additionally, you can search The U.S. Will Registry. This national registry tracks wills registered by individuals, attorneys, and institutions. Registration helps document where the will or trust is stored—whether at home, with an attorney, or another trusted party.

Once you find the will, you must submit it to the probate court if it isn’t already on file. Some states consider it a crime to withhold a will from the court if you possess it.

The executor—or the person applying to become the executor—must then file a petition to begin probate. As part of this process, the court will decide what constitutes a valid will.

What Constitutes a Valid Will in Legal Terms?

Each state has its own laws on what constitutes a valid will, but generally, a will is valid if:

• The testator (person making the will) has mental capacity.
• The will is written.
• The testator signs and dates the will.
• Two witnesses sign the will.

While registration isn’t required for a will to be valid, it does help families locate the document when needed.

Legal and Testamentary (Mental) Capacity

To meet the legal definition of what constitutes a valid will, the testator must have capacity. This means the person is usually at least 18 years old, although exceptions exist for married individuals and active military members.

Testamentary capacity means the person must be of sound mind. This includes understanding:

• • • The purpose of making the will.
    • What property they own.
    • Who their family members are.
    • That they are deciding who receives their property.

The person must have this understanding at the time of signing the will.

Testamentary Intent

Intent is another requirement of what constitutes a valid will. The testator must intend for the document to act as their will. This is often proven by their actions and the wording of the document.

Intent and capacity are common grounds for will challenges. Family members may claim the testator wasn’t mentally capable or did not intend the document to be their legal will.

The Will Must Be in Writing

Another key part of a valid will is that it must be in writing. This can be typed or printed. Some states allow handwritten (holographic) wills, but these come with additional legal hurdles. Holographic wills are not recognized in every state and can be difficult to validate.

Self-printed or handwritten wills often face extra scrutiny during probate because they may lack important legal language.

The Testator Must Sign and Date the Will

Signing and dating the document is essential.  If the testator cannot physically sign, they may direct someone else to sign on their behalf. Courts generally accept electronic signatures when legally permitted.

Two Witnesses Must Sign the Will

Most states require two adult, competent witnesses to watch the testator sign the will. Witnesses usually cannot be people who benefit from the will. This rule helps avoid conflicts of interest.

Does a Valid Will Need to Be Notarized?

While notarization is not a requirement in most states, adding a self-proving affidavit can speed up probate. This affidavit, signed by the testator and witnesses in front of a notary, confirms that all legal steps were followed. Including this affidavit makes the court’s job easier.

What to Look for If You Believe the Will is not Valid

When reviewing a will, you might wonder what constitutes a valid will if something seems suspicious. Spotting warning signs early protects the estate and the rightful heirs. Let’s explore exactly what you should look for.

1. Last-Minute or Unusual Changes

Start by checking for last-minute changes. If the will looks completely different from earlier versions, you should take note. This is especially true if the new version removes close family members without explanation. Such changes often signal possible manipulation or undue influence.

2. Signs of Mental Decline

You should also watch for signs of mental incapacity. If the person suffered from memory loss, confusion, or illness, the will may not meet legal requirements.
Common signs include:

• • A diagnosis of dementia or Alzheimer’s.
  • Inability to recognize family or recall important details.
  • Uncharacteristic or irrational decisions.

If you notice these signs, you have a valid reason to question what constitutes a valid will.

3. Pressure or Undue Influence

Another red flag appears when someone pressures the person to change their will. You might notice a new friend or caregiver suddenly becoming the main beneficiary.
Look for these signs:

• • The person isolating the testator from family.
  • The testator changing their will under someone else’s direction.
  • The beneficiary taking over decision-making.

These situations often require legal review to ensure the will reflects the true wishes of the deceased.

4. Missing or Improper Witnesses

You should confirm that the will includes the correct witness signatures. In most states, two unbiased adult witnesses must watch the signing.
Look for these problems:

• • Fewer than two witnesses.
  • Witnesses who also receive an inheritance.
  • No witness signatures at all.

Mistakes like these can make the will invalid.

5. Poorly Prepared Handwritten or Self-Printed Wills

While handwritten or printed wills can sometimes be valid, they often lack important legal language. Courts tend to question these wills more closely.
Check for:

• • Missing witness signatures.
  • No self-proving affidavit.
  • Poor wording or incomplete information.

If you spot these problems, you should consult an attorney to review the will’s validity.

6. Forgery or Fraud Concerns

Lastly, you should stay alert for forgery or fraud.
Ask yourself:

• • Does the handwriting look different from known examples?
  • Does the signature appear shaky or inconsistent?
  • Did the will suddenly appear without anyone knowing about it before?

If you answer yes to any of these questions, you should contact a legal professional right away. Expert testimony may be needed to prove what constitutes a valid will.

What Happens if the Will Is Invalid?

If the court decides the will is invalid, state intestate succession laws will apply. These laws dictate who inherits based on family relationships. Spouses, children, parents, and siblings typically receive priority.

For example:

• A surviving spouse often receives the largest share.
• If children survive the decedent, they share the estate with the spouse.
• If no spouse or children survive, parents or siblings may inherit.
