How to Write a Will in America: Requirements, Costs and Options (2026)

More than half of American adults do not have a will. Without one, the state decides who gets your assets, who raises your children, and who manages your estate. Writing a will does not have to be expensive or complicated. This guide covers everything you need to know: state-specific legal requirements, the different types of wills, how much each option costs, what to include, and the most common mistakes that can invalidate your wishes.

Why Every Adult Needs a Will

A will is a legal document that specifies how your assets should be distributed after your death. Without one, your state's intestacy laws take over, and the results may not match your wishes at all.

You choose who inherits. Without a will, state law dictates the split. In many states, a surviving spouse does not automatically receive everything; children, parents, or siblings may claim a portion.
You name a guardian for minor children. This is the single most important reason for parents to have a will. Without one, a court decides who raises your children, and it may not be the person you would choose.
You choose your executor. The executor (also called a personal representative) manages your estate through probate. Without a will, the court appoints someone, often a family member who may not be the best fit.
You can minimize family disputes. A clear, legally valid will reduces the likelihood of family conflicts over who gets what.
You can reduce costs. Dying intestate typically results in a more expensive and time-consuming probate process.

Types of Wills

There are several types of wills recognized in the United States, each with different requirements and levels of legal protection:

Typed (Formal) Will

The most common and widely accepted type. A typed will is printed, signed by the testator (the person making the will), and signed by the required number of witnesses. This is what attorneys prepare and what online will services generate. It is valid in all 50 states when properly executed.

Holographic (Handwritten) Will

A holographic will is written entirely in the testator's handwriting and signed by the testator. Many states accept holographic wills without witnesses, but not all states recognize them. States that accept holographic wills include:

Alaska, Arizona, Arkansas, California, Colorado, Hawaii, Idaho, Kentucky, Louisiana, Maine, Michigan, Mississippi, Montana, Nebraska, Nevada, New Jersey, North Carolina, North Dakota, Oklahoma, Pennsylvania, South Dakota, Tennessee, Texas, Utah, Virginia, West Virginia, and Wyoming.

Pour-Over Will

A pour-over will works alongside a living trust. Any assets not already in the trust at the time of death are "poured over" into the trust through this will. It still goes through probate, but it ensures everything ends up in the trust for distribution according to its terms.

Joint Will

A single will signed by two people, usually spouses. Joint wills are uncommon today because they create a binding agreement that the surviving spouse cannot change after the first spouse dies. Most estate planners recommend separate wills for each spouse instead.

Oral (Nuncupative) Will

A spoken will made before witnesses, typically only valid in emergency situations (such as imminent death). Very few states recognize oral wills, and those that do usually limit the value of assets that can be distributed this way. This should never be relied upon as your primary estate plan.

State Requirements for a Valid Will

While the general requirements for a valid will are similar across states, important differences exist. Here are the universal requirements and the key variations:

Requirements in All States

The testator must be at least 18 years old (some states allow younger if married or in the military)
The testator must be of "sound mind" (understanding what they own, who their heirs are, and what the will does)
The will must be signed by the testator (or by someone at the testator's direction in their presence)
The will must be created voluntarily, without undue influence or duress

Requirement	Details
Witnesses	Most states require 2 witnesses. Vermont requires 3. Witnesses must be "disinterested" (not beneficiaries) in most states.
Notarization	Louisiana requires notarization. All other states accept wills without notarization, but a notarized self-proving affidavit is recommended everywhere.
Self-proving affidavit	Available in all states except DC, Maryland, Ohio, Vermont, and Wisconsin. This notarized statement by witnesses eliminates the need to locate them during probate.
Holographic wills	Recognized in about 27 states. Must be entirely in the testator's handwriting and signed. No witnesses required in most states that accept them.
Electronic wills	A growing number of states now accept electronic wills, including Nevada, Indiana, Arizona, Colorado, Utah, and Florida. Requirements vary by state.

Important: Louisiana Is Different

Louisiana's will requirements are unique because its legal system is based on French civil law rather than English common law. Louisiana requires a notary and two witnesses for a typed will (called a "notarial testament"). Louisiana also has forced heirship laws that require a portion of the estate to go to children under 24 or permanently disabled children, regardless of what the will says.

What to Include in Your Will

A thorough will covers all the important decisions your family would otherwise have to guess about or fight over:

Identification. Your full legal name, date of birth, address, and a statement that this is your last will and testament, revoking all prior wills.
Executor (personal representative). Name the person responsible for managing your estate through probate. Also name a backup executor in case your first choice is unable or unwilling to serve.
Guardian for minor children. If you have children under 18, name a guardian and a backup guardian. Courts give strong weight to the parents' wishes expressed in a will.
Specific bequests. List any specific items or dollar amounts you want to go to specific people (for example, "My engagement ring to my daughter Sarah" or "$10,000 to my nephew Michael").
Residuary estate. Specify who receives everything else (the "residue") after specific bequests are fulfilled. This is often the bulk of the estate.
Contingent beneficiaries. Name alternate beneficiaries in case your primary beneficiaries die before you.
Debts and taxes. Specify whether debts and estate taxes should be paid from the general estate or charged to specific bequests.
Funeral preferences. While not legally binding in most states, expressing your burial or cremation preferences guides your family. See our funeral cost guide for cost planning.
Digital assets. Include instructions for online accounts, social media, email, cryptocurrency wallets, and digital files. See our digital legacy planning guide.
Pet care. Name someone to care for your pets and set aside funds for their care. Some states allow enforceable pet trusts.

How Much Does It Cost to Write a Will?

The cost ranges from essentially free to several thousand dollars depending on the complexity of your estate and the method you choose:

DIY Will vs. Hiring an Attorney

A DIY will (whether handwritten, from a kit, or from an online service) is legally valid when properly executed. But there are situations where an attorney is worth the investment:

DIY Will Is Usually Fine When:

Your estate is straightforward (house, bank accounts, retirement accounts)
You are leaving everything to your spouse and/or children
You live in one state and own property in only that state
You do not own a business
There are no family disputes or disinheritance concerns
Your estate is below the state estate tax threshold

Hire an Attorney When:

You own property in multiple states
You have a blended family (children from different marriages)
You want to disinherit someone
You own a business or partnership interests
Your estate may owe state or federal estate tax
You want to set up a trust (special needs, spendthrift, etc.)
You have complex assets (stock options, intellectual property, crypto)
You live in Louisiana (unique legal requirements)

10 Common Mistakes That Can Invalidate Your Will

Not having enough witnesses. If your state requires two witnesses and you only have one, the entire will may be invalid. Always check your state's requirements.
Using beneficiaries as witnesses. In many states, if a witness is also a beneficiary, that witness's inheritance is voided (or the entire will is challenged). Use disinterested witnesses.
Not revoking prior wills. If you create a new will but do not explicitly revoke the old one, both may be submitted to probate, causing confusion and legal disputes.
Forgetting to update after major life events. Marriage, divorce, birth of a child, or death of a beneficiary all require will updates. Many states automatically revoke provisions for an ex-spouse after divorce, but not all.
Not accounting for all assets. If your will does not include a residuary clause (covering "everything else"), assets not specifically mentioned pass through intestacy laws.
Contradicting beneficiary designations. Life insurance, 401(k), and IRA beneficiary designations override your will. If your will says one thing and the beneficiary form says another, the beneficiary form wins.
Vague language. "I leave my jewelry to my daughters" without specifying which pieces go to whom is a recipe for disputes. Be specific.
Not including a self-proving affidavit. While not required for validity, the absence of a self-proving affidavit means your witnesses may need to be located and testify during probate, which can cause delays.
Improper storage. Keeping your will in a safe deposit box can create problems because the box may be sealed after death. Store the original with your attorney, in a fireproof home safe, or file it with your county probate court (many states allow this).
DIY modifications. Crossing out lines, writing in margins, or adding sticky notes to an existing will can invalidate the entire document. Changes should be made through a formal codicil (amendment) or a new will.

When and How to Update Your Will

A will is not a one-time document. You should review it every three to five years and update it whenever a major life event occurs:

Marriage or divorce
Birth or adoption of a child
Death of a beneficiary or executor
Significant change in assets (inheritance, sale of property, new business)
Moving to a different state
Change in tax laws that affects your estate
Falling out with a beneficiary

You can update a will in two ways: execute a codicil (a formal amendment that must meet the same witness requirements as the original will) or create an entirely new will that explicitly revokes the old one. For significant changes, a new will is usually cleaner and less likely to cause confusion.

Frequently Asked Questions

How much does it cost to write a will?

The cost depends on the method you choose. Online will services cost $69 to $200, DIY will kits cost $20 to $50, and hiring an estate planning attorney costs $300 to $1,000 or more for a basic will. Complex estates with trusts or business interests can cost $2,000 to $5,000+ for a comprehensive estate plan.

Can I write my own will without a lawyer?

Yes, you can legally write your own will in all 50 states. However, you must follow your state's requirements for witnesses, signatures, and formatting. A DIY will works well for simple estates, but complex situations involving businesses, blended families, or significant assets benefit from professional legal guidance.

How many witnesses do I need for a will?

Most states require two witnesses who watch you sign the will and then sign it themselves. Vermont requires three witnesses. Witnesses should be disinterested parties, meaning they do not inherit anything under the will. Some states allow notarization as an alternative to or in addition to witnesses.

What happens if you die without a will?

If you die without a will (intestate), your state's intestacy laws determine who inherits your assets. Typically, your spouse and children inherit first. If you have no spouse or children, assets pass to parents, siblings, and then more distant relatives. Dying intestate also means a court appoints your estate administrator and guardian for minor children.

Do I need to notarize my will?

Most states do not require notarization for a will to be valid. However, adding a notarized self-proving affidavit is highly recommended because it speeds up probate by eliminating the need to locate witnesses later. Louisiana is the only state that requires notarization as part of the will execution process.
