How Much Does a Will Cost in Missouri?

Published June 11, 2026 7 min read

Quick answer

A simple will in Missouri typically costs about $300 to $1,000 with an attorney, and $0 to $150 online. Missouri does not recognize handwritten (holographic) wills, so you can't skip the two-witness step. The honest point is that a will is cheap because it doesn't avoid probate — it directs your estate through Missouri probate, it doesn't skip it. If avoiding probate is the goal, that's a living-trust question.

A simple will in Missouri is genuinely inexpensive — $300 to $1000 with an attorney, and as little as $0 online. The price is low for a reason: a will is a relatively simple document. The cost climbs only when your situation is complicated — minor children and a guardianship decision, a blended family, a business, or potential estate tax.

What makes a will valid in Missouri

A Missouri will must be in writing, signed by the testator (or by someone at the testator's direction and in the testator's presence), and attested by two or more competent witnesses who sign in the testator's presence (Mo. Rev. Stat. §474.320).

The witnesses should be disinterested — that is, not people who inherit under the will — so no one can later argue they had a reason to lie about the signing. Get that one detail wrong and the gift to an interested witness (or the whole will) can be challenged.

Can you write your own will by hand in Missouri?

Missouri does NOT recognize holographic (handwritten, unwitnessed) wills. Every will must be in writing, signed by the testator, and attested by two or more competent witnesses (Mo. Rev. Stat. §474.320).

Even where a handwritten will is legal, it’s the riskiest way to do it: no witnesses means no one to confirm it was really you and that you weren’t pressured, and ambiguous handwriting is a gift to anyone who wants to contest it. A typed, witnessed, self-proved will costs very little and avoids all of that.

The self-proving affidavit (a small step that saves a big headache)

Missouri allows a self-proving affidavit under Mo. Rev. Stat. §474.337 — the testator and witnesses acknowledge the will before a notary, so the will can be admitted to probate without further proof and the witnesses don't need to testify.

Without it, your witnesses may have to be tracked down years later to confirm they watched you sign — which can be impossible if they’ve moved, lost touch, or died. It’s one of the cheapest, highest-value things you can add to a will.

The catch: a will doesn’t avoid probate in Missouri

This is the part the price tag hides. A will is cheap because of what it doesn’t do: it does not avoid probate. A will simply tells the Missouri probate court who should get what and who should run the estate. Everything it covers still goes through probate — the public, months-long, fee-charging court process.

So the real cost of “just a will” isn’t the $0–$1,000 you pay now; it’s the probate your family pays later. To see that number for Missouri, read How Much Does Probate Cost in Missouri?.

Do you need more than a will in Missouri?

For a lot of people, a will is genuinely enough — especially renters, younger families, and anyone whose main assets (retirement accounts, life insurance) already pass by beneficiary designation outside probate.

You may want more than a will if you own a home and want to spare your family probate, value privacy, own property in more than one state, or want a plan for incapacity. That’s where a living trust comes in — it costs more up front but can avoid probate entirely. Compare the two honestly:

How to keep the cost down in Missouri

  • Use a quality online service for a truly simple estate. Several are free; paid ones run $0–$150. Make sure it’s Missouri-specific and includes a self-proving affidavit.
  • Bundle the basics. A will, a financial power of attorney, and a healthcare directive are cheaper together than separately — and the POA and directive matter while you’re alive, which a will never does.
  • Pay for an attorney when it’s not simple. Minor children, a blended family, a business, a special-needs beneficiary, or estate-tax exposure are all worth a real attorney’s time. A cheap will that’s invalid or unclear is the most expensive kind.

The honest takeaway

A will in Missouri costs $300 to $1000 with an attorney, or nearly nothing online — and for many people that’s all they need. Just go in clear-eyed about what you’re buying: a will directs your estate through probate; it doesn’t avoid it. If avoiding probate matters to you, price a living trust against what Missouri probate would actually cost your family, and decide from there.

Whatever you choose, sign it correctly with two disinterested witnesses, add the self-proving affidavit where Missouri allows it, and tell your executor where to find it.
