Missouri estate planning
Make a will, living trust & powers of attorney in Missouri
Missouri sets its own rules for who can make a will, how it must be signed and witnessed, whether it needs a notary, and how estates are taxed. Estateur drafts your Missouri will, revocable living trust, and powers of attorney through a guided interview, then validates every document against Missouri law before you ever see it. It is a self-help document-preparation service, not a law firm.

How to make a valid will in Missouri
A Missouri will must be in writing and signed by you in front of two witnesses. Notarization is not required for the will to be valid, but a self-proving affidavit — which is notarized — makes probate easier by removing the need for your witnesses to testify later. Missouri does not recognize handwritten (holographic) wills — the witness requirement applies regardless. Missouri permits electronic wills under its own statute.
Spousal protection. Elective share: 1/2 (no descendants) or 1/3 (with descendants) of estate (RSMo § 474.160). A will can't fully disinherit a surviving spouse in most states — Estateur's interview flags this for you.
Living trusts & avoiding probate in Missouri
A will still has to pass through Missouri probate — a public, court-supervised process — before your assets reach your heirs. A revocable living trust holds your assets during life and transfers them at death without probate, which is usually faster and stays private. A trust is not right for everyone; it depends on whether you own real estate, the size and complexity of your estate, and your goals.
Estateur's free quiz recommends whether a will-based or trust-based plan fits your Missouri situation, and every trust-based plan includes a pour-over will as a companion document.
Powers of attorney & healthcare directives in Missouri
A financial power of attorney in Missouri must be acknowledged before a notary to be effective. (RSMo § 404.705)
A Missouri healthcare directive can be signed before either two witnesses or a notary. (RSMo § 404.810)
A complete plan also includes a HIPAA authorization so your healthcare agent can actually get your medical information. Estateur builds each of these to Missouri's signing rules and includes execution instructions.
Missouri estate & inheritance tax
Missouri has no state estate tax and no state inheritance tax. Only the federal estate tax can apply, and it affects very few estates.
Estate-tax exemption amounts are 2025 figures and change annually. Confirm current thresholds with the Missouri department of revenue.

Missouri estate planning: common questions
- Is an online will legal in Missouri?
- Yes. Missouri does not care who typed your will — it cares that the will meets Missouri's execution rules. A will is valid in Missouri when it is in writing, signed by you, and witnessed by two people (RSMo § 474.320). Estateur builds each Missouri will to those rules and includes step-by-step signing instructions, so an online will you sign correctly is just as valid as one prepared any other way.
- How many witnesses does a will need in Missouri?
- Missouri requires two witnesses to sign your will. Adding a notarized self-proving affidavit is optional but recommended — it lets the will be admitted to probate without tracking down your witnesses. Missouri does not recognize handwritten (holographic) wills.
- Do I need a lawyer to make a will in Missouri?
- No. Missouri law does not require a lawyer to make a valid will — you can prepare and sign your own. Estateur is a self-help document-preparation service (not a law firm, and no attorney personally reviews each plan) that drafts your Missouri documents against the state's verified rules and validates them before you see them. For complex situations — large or taxable estates, blended families, special-needs beneficiaries, or business succession — consulting a licensed Missouri attorney is wise.
- Does Missouri have an estate tax or inheritance tax?
- Missouri has no state estate tax and no state inheritance tax. Only the federal estate tax can apply, and it affects very few estates.
- How much does an online will cost in Missouri?
- Estateur uses flat, one-time pricing that is the same in Missouri as in every other state: a single Last Will & Testament is $79, or the full Will Plan (seven documents) is $99, with no subscription required.
