Can I Write My Own Will? What the Law Actually Says

The short answer is yes — in most states, you can write your own will, and it will be legally valid if it meets the state's requirements. The longer answer is that the requirements vary, the consequences of getting them wrong are severe (your will is rejected by the probate court and you effectively died intestate), and there are specific situations where you genuinely need an attorney. Here's what you need to know.

The Two Types of Wills You Can Write Yourself

Most wills fall into one of two categories: attested wills and holographic wills.

An attested will is the standard form: a typed document that you sign in front of witnesses. Every U.S. state recognizes attested wills. The requirements are similar across states but differ in the details. Generally, you must be 18 or older (or legally emancipated), of "sound mind" (meaning you understand what a will is, what you own, and who your natural heirs are), and you must sign the will in the presence of two adult witnesses. Most states require the witnesses to sign in your presence and in the presence of each other. Some states additionally require a notary.

A holographic will is one written entirely in your own handwriting, signed, and dated — no witnesses required. About half the states recognize holographic wills: California, Texas, Alaska, Arizona, Arkansas, Colorado, Idaho, Kentucky, Louisiana, Maine, Michigan, Mississippi, Montana, Nebraska, Nevada, New Jersey, North Carolina, North Dakota, Oklahoma, Pennsylvania, South Dakota, Tennessee, Utah, Virginia, West Virginia, Wisconsin, and Wyoming (list subject to legislative change). The requirements vary — some states require the entire will to be in the testator's handwriting; others allow printed portions if the material provisions (what goes to whom) are handwritten.

States That Don't Recognize Holographic Wills

If you live in Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Maryland, Minnesota, Missouri, New Hampshire, New Mexico, New York, Ohio, Oregon, Rhode Island, South Carolina, or Vermont, a handwritten will without witnesses is not valid. A will must be attested — typed or printed, signed, and witnessed — to be recognized by the probate court. Creating a holographic will in one of these states is the same as not having a will.

What Can Make a Self-Written Will Invalid

Even in states that allow self-drafted wills, common mistakes can invalidate them. Failing to sign in the presence of all witnesses simultaneously is a frequent problem — all signatures need to happen at the same time and place. Having a beneficiary witness the will (someone who is named to receive property) is disqualifying in many states or can void the gift to that witness. Lack of testamentary capacity at the time of signing — signing while under the influence, during a medical crisis, or when suffering from dementia — can be challenged in probate court, especially if family members contest the will.

Ambiguous language is another common problem: "I leave my house to my children" is fine if you have two children, but creates a dispute if you later have a third child and didn't update the will. "I leave 50% of my estate to my brother Tom" is fine as long as Tom is alive when you die — what happens if he predeceases you? Wills drafted without legal training often fail to address these contingencies.

Self-Proving Affidavits: Worth the Extra Step

A self-proving affidavit is a notarized statement signed by you and your witnesses at the time you execute the will. It serves one purpose: the witnesses won't need to appear in probate court to verify their signatures when you die. In most states, adding this affidavit simply requires going to a notary with your witnesses immediately after signing. It's a small extra step that can save your estate significant time and expense.

Most states recognize self-proving affidavits under their version of the Uniform Probate Code. Check your state's specific requirements for the required language.

When an Attorney Is Truly Necessary

A DIY will is appropriate for people with relatively simple estates: clear beneficiaries, no substantial business interests, no significant real estate in multiple states, no blended family complications, and no expectation of estate tax liability (federal estate tax only applies to estates over $13.61 million in 2024).

You should consult an estate planning attorney if you have minor children from multiple relationships, are in a second marriage with children from a prior marriage, own business interests, have a beneficiary with special needs (a special needs trust is often preferable to a direct inheritance that could disqualify them from government benefits), expect family conflict over the estate, own real estate in multiple states, or have a taxable estate. These situations require planning beyond what a basic will provides.

For everyone else, a properly executed will — drafted with care and executed according to your state's requirements — is far better than nothing. A last will and testament is the foundational document of any estate plan, and there's no good reason to leave your family without one.
