How to Write a Will Without a Lawyer: Requirements, Steps, and 5 Common Mistakes
You can write a legally valid will without a lawyer in all 50 US states, as long as the document meets your state’s requirements for signing and witnessing. A will names who inherits your property, appoints a guardian for minor children, and designates an executor to carry out your wishes after you die.
This article provides general information and isn’t a substitute for legal advice. State requirements vary and change over time, so verify your state’s current rules or consult a licensed attorney for a complex estate.
Can You Legally Write Your Own Will Without a Lawyer?
Yes, every US state allows you to write your own will without hiring an attorney, provided the document meets that state’s requirements for execution and witnessing. A self-written will carries the same legal weight as an attorney-drafted one once it’s properly signed and witnessed.
Millions of Americans create their own wills each year using templates, will-writing software, or a plain sheet of paper. The document’s validity depends entirely on following your state’s formal requirements, not on who wrote it. See our State-Specific Will Requirements Guide for rules by state.
What Are the Legal Requirements for a Valid Will?
A valid will requires four elements in nearly every state: the testator must be at least 18 years old, have testamentary capacity, sign the document, and have it witnessed according to state law.
Testamentary capacity, the legal term for having a sound mind, means you understand four things at the time you sign: the nature and extent of your property, who your close relatives and natural heirs are, what a will legally does, and how these pieces connect into a coherent plan. Courts have used this same basic test since the 1870 UK case Banks v. Goodfellow, which US courts still cite as the foundation for testamentary capacity today.
Most states require two witnesses who are legal adults and not named as beneficiaries in the will, since an interested witness can create grounds for a legal challenge.
What Types of DIY Wills Are There?
A DIY will generally takes one of two forms: a typed, witnessed will or a handwritten holographic will. The table below compares them.
| Feature | Typed (Attested) Will | Holographic Will |
|---|---|---|
| Format | Typed or printed | Entirely handwritten |
| Witnesses | Usually 2 required | Often not required |
| State recognition | All 50 states | About 27 states plus DC |
| Best for | Most situations | Emergency or last-minute planning |
| Contest risk | Lower, with proper witnessing | Higher, due to handwriting disputes |
Roughly 27 states and the District of Columbia recognize holographic wills, while the rest reject them for residents. A typed, witnessed will holds up better in probate court, since a handwritten will can face challenges over authenticity or unclear intent.

How Do You Write a Will Step by Step?
- List your assets and beneficiaries. Identify property, accounts, and possessions, and decide who inherits each one.
- Choose an executor. Name someone to carry out the will’s instructions and settle the estate, plus a backup choice.
- Name a guardian for minor children. Appoint a guardian if you have children under 18, along with a backup guardian.
- Write the will’s terms. Use a state-specific template or will-writing software to draft the document in clear, unambiguous language.
- Sign in front of witnesses. Sign the will in the physical presence of your witnesses, and have them sign in your presence too.
- Store the original safely. Keep the signed original in a fireproof safe or with your executor, and tell your executor where to find it.

What Should You Include in a Will?
A complete will covers six core elements:
- Your full legal name and a statement that this is your last will and testament
- Your executor’s name and at least one backup executor
- Specific bequests, naming who receives particular property
- A residuary clause, which assigns any property not specifically listed
- Guardianship instructions for minor children, if applicable
- Your signature, the date, and your witnesses’ signatures
Do You Need a Self-Proving Affidavit?
A self-proving affidavit isn’t required to make a will valid, but it speeds up probate significantly. The affidavit is a notarized statement, signed by your witnesses, confirming they watched you sign the will while you appeared to have sound mind.
Without a self-proving affidavit, a probate court may need to track down your witnesses to testify after your death, which can delay the process by weeks or months. Every state except the District of Columbia, Maryland, Ohio, and Vermont allows a self-proving affidavit.
What Are Common Mistakes That Invalidate a DIY Will?
Five mistakes account for most of the DIY wills that fail in probate court.
- Using an interested witness. A witness who is also a beneficiary can create a conflict of interest that some states use to invalidate their inheritance or the entire will.
- Signing outside a witness’s presence. Witnesses must watch you sign, or you must sign in their presence, not review the document afterward.
- Skipping the residuary clause. Without one, any property not specifically named in the will passes under state intestate succession law instead of your wishes.
- Leaving out a guardian for minor children. A court appoints a guardian without your input if the will doesn’t name one.
- Failing to update the will after major life changes. A marriage, divorce, birth, or death in the family can make an outdated will’s instructions unclear or legally void in part.
When Should You Hire a Lawyer Instead of DIY?
A DIY will works well for a simple estate, but several situations call for professional legal help instead.
- You own a business or have complex assets that need specific transfer instructions
- You want to minimize estate taxes or set up a revocable living trust to avoid probate
- You have a blended family and want to balance a current spouse’s and children’s inheritances
- You have a beneficiary with special needs, since a direct inheritance can affect their government benefits
- You expect a family member to contest the will after your death
An estate planning attorney can also review a will you’ve already drafted yourself, which costs less than a fully attorney-drafted will while catching errors a template might miss.
How Much Does a DIY Will Cost Compared to a Lawyer?
| Option | Typical Cost | Turnaround |
|---|---|---|
| Handwritten will | Free | Same day |
| Will-writing software or template | $0 to $100 | Same day |
| Online estate planning service | $50 to $500 | A few days |
| Attorney-drafted will | $300 to $1,200 or more | 1 to 3 weeks |

Frequently Asked Questions About Writing a Will Without a Lawyer
Does a DIY will need to be notarized to be valid?
No. Notarization isn’t required for a will’s basic validity, only witness signatures are. Notarization becomes relevant only for the optional self-proving affidavit.
Can I write my own will on plain paper?
Yes, in states that recognize holographic wills. The document must be entirely in your own handwriting and signed, though a typed and witnessed will is accepted everywhere and holds up better in probate.
What happens if I die without a will?
Your assets pass under your state’s intestate succession laws, which distribute property to relatives in a fixed order that may not match your actual wishes.
Can I change my will after I write it?
Yes. You can revoke or update a will at any time while you have testamentary capacity, either by writing a new will or adding a signed, witnessed codicil.
Is a DIY Will Right for You?
A DIY will works for a simple estate: a single beneficiary group, no business ownership, and no expected disputes among heirs. Following your state’s signing and witnessing rules exactly, and adding a self-proving affidavit where available, gives a self-written will the best chance of holding up in probate.
A blended family, a business, a large estate, or an anticipated challenge from an heir all shift the balance toward hiring an estate planning attorney instead. Either way, the biggest risk isn’t doing it yourself, it’s doing it incorrectly.
