The Complete Guide
On August 28, 2025, Missouri quietly did something most states still haven’t: it made the fully electronic estate plan a legal reality. No conference room. No drive across the county. No safe-deposit box your family can’t open. This is the complete guide to what the law does, how it works, and why it matters for Missouri families.
For roughly 450 years, the rules for making a valid will barely changed. Missouri inherited its core requirements from the English Statute of Frauds of 1677, and for the last six decades every Missouri lawyer learned the same three: a will must be in writing, signed by the testator, and witnessed by two competent witnesses in the testator’s presence. The Missouri Electronic Wills and Electronic Estate Planning Documents Act doesn’t throw those protections out. It brings them into the era of the smartphone and the cloud, and the result is one of the most modern estate planning frameworks in the country.
What the Law Actually Is
The Act is codified at Sections 474.540 through 474.564 of the Revised Statutes of Missouri, with a companion provision at 474.600. It took effect August 28, 2025, and applies to the estate of anyone who dies on or after that date, as well as to estate planning documents signed or witnessed remotely on or after it.
Its foundational rule is disarmingly simple, and it’s the sentence everything else rests on: an electronic will is a will for all purposes of Missouri law. The ordinary law of wills and the principles of equity apply to it exactly as they would to a paper will, except where the Act modifies them. In other words, going electronic doesn’t create a lesser, second-class document. It creates the same legally binding instrument in a different medium.

The Building Blocks
The Act is short, but each section does specific work. Understanding the architecture makes the whole thing far less mysterious.
What counts as an electronic will (474.548). An electronic will must be a record that is readable as text at the time of signing, signed by the testator (or by another person in the testator’s name, in the testator’s physical presence, and at the testator’s direction), and signed by at least two witnesses. Those witnesses must act in the physical or electronic presence of the testator, after watching the testator sign or after the testator acknowledges the signature or the will.
What “electronic presence” means. This is the hinge of the entire law. Electronic presence is defined as two or more people in different locations, in real time, using technology that allows live, interactive audio-visual communication, observation, and direct interaction. That single definition is what lets a witness in one town validly observe a signing in another.
The self-proved electronic will (474.550). A self-proving affidavit is what spares your family from having to track down witnesses years later to confirm a will is genuine. Under the Act, an electronic will can be made self-proved before a remote online notary, using a special remote online notarial certificate, even when fewer than two witnesses are physically present. This is one of the most practical features of the law: it makes probate smoother before there’s ever a problem to solve.
Out-of-state execution (474.546). A will executed electronically that doesn’t perfectly satisfy Missouri’s formal requirements can still be a valid electronic will here if it complied with the law of the place where the testator was physically located or domiciled when signing. This matters for families with members spread across state lines.
Digital assets (474.554). The Act includes provisions for the disclosure of digital assets needed to obtain an electronic will, acknowledging a reality paper-era law never anticipated: that the will itself, and the assets it governs, increasingly live in digital form.

More Than Wills: The Whole Plan
A common misunderstanding is that this law is only about wills. It is not. Section 474.560 extends electronic execution to the full toolkit of estate planning, providing that any written estate planning document may be executed electronically and is not invalid solely because it is in electronic form or electronically signed. That expressly includes:
- Financial and durable powers of attorney — authorizing someone to handle your financial affairs.
- Healthcare powers of attorney and advance directives — naming who speaks for your medical care and setting out your wishes.
- Revocable living trusts — the workhorse instrument for avoiding probate and managing assets.
For these non-will documents, the witnessing rule is even more flexible: any document other than a will that requires witnesses to the principal’s signature may be witnessed by individuals in the electronic presence of the principal. A complete plan — will, trust, financial power of attorney, and healthcare directive — can therefore be assembled and executed in one coordinated, remote process.

The Heart of It: Remote Notarization
The engine that makes all of this work is remote online notarization, or RON. Instead of physical presence, you and a commissioned Missouri notary meet over a secure, real-time, two-way audio-video connection.
Missouri takes the integrity of that session seriously. A notary cannot simply opt in. To perform remote notarizations, a notary must register separately as an electronic notary with the Secretary of State — a distinct step beyond a standard commission — after completing approved training on Missouri’s remote notarization law, identity verification, and platform compliance. The process itself layers identity proofing through knowledge-based authentication and credential analysis of a government ID, a recorded session, and a maintained electronic journal.
The result is counterintuitive but important: a properly conducted remote signing often leaves a stronger evidentiary trail than the traditional conference-table version, where the only proof a signing happened correctly is the paper itself and the recollections of those in the room.

The Real Benefits for Missouri Families
Access for everyone, everywhere. Rural residents no longer measure estate planning in hours of driving. People with limited mobility or health challenges can complete a full plan from home. Families separated by distance can coordinate without anyone booking a flight. The single biggest reason people never finish an estate plan — the friction of getting everyone in one room — largely disappears.
Your documents aren’t trapped in a vault. This is one of the quietest but most meaningful shifts. A paper will locked in a bank safe-deposit box can become a genuine crisis after death: the box may be sealed, access may require a court order, and grief-stricken families have lost weeks to the simple problem of physically retrieving the document. An electronic estate plan, properly stored, is retrievable when it’s needed, by the people who need it, without prying open a steel drawer at the bank.
A document that’s actually findable. The flip side of the storage rule (more on the caution below) is that doing it correctly means your plan is stored deliberately, with certified paper copies and clear instructions, rather than tucked in a drawer no one remembers.
Speed without sacrificing validity. What once took weeks of appointments can often be completed in a single coordinated sitting — and the finished electronic plan carries precisely the same legal force as a stack of pen-and-ink originals.
Easier to keep current. Life changes — marriage, children, a new home, a business. Because the documents are electronic, revisiting and updating them is far less burdensome, which means plans are more likely to stay accurate instead of going stale.

The Caution That Matters Most
No honest guide to this law would skip its sharpest edge. Under Section 474.552, if a testator signed an electronic will and, after death, neither the electronic will nor a certified paper copy can be located, the law presumes the will was revoked — even if no document revoking it exists, and even if revocation was never intended.
With a paper will, a lost copy is a setback. With an electronic will, a lost copy can erase the entire plan. The Act provides the remedy in the same breath: under Section 474.556, anyone may create a certified paper copy of an electronic will by affirming under penalty of perjury that it is a complete, true, and accurate copy, and Missouri courts must accept it. The same certified-copy mechanism applies to other electronic estate planning documents under 474.560. There’s also a practical recording rule worth knowing: a will that passes real estate must be recorded in the appropriate county within six months of probate, which makes accessible storage not merely prudent but necessary.
The throughline is simple. The technology is excellent; it rewards being used carefully. That is precisely the difference between a fill-in-the-blanks website and an attorney who builds the safeguards in from the start.

A Note on Where This Came From
Missouri didn’t arrive here by accident. During the COVID-19 emergency, executive orders temporarily suspended physical-presence requirements and allowed audio-visual technology for executing estate planning documents. Section 474.600 of the Act goes back and confirms the validity of documents executed under those emergency procedures, giving lasting certainty to plans made during that period. The 2025 Act takes the lesson of that experiment — that remote execution can be done securely — and makes it permanent, deliberate, and properly regulated.
The Bottom Line
Missouri’s Electronic Wills and Electronic Estate Planning Documents Act is not a gimmick or a shortcut. It is a carefully constructed framework that preserves the centuries-old protections of valid estate planning while removing the logistical barriers that have kept too many families from ever finishing a plan. Used well — with proper witnessing, remote notarization, and deliberate storage — it offers Missouri families something genuinely valuable: a complete, legally binding estate plan that fits into real life.
The most important step remains the one too many people postpone: starting. The law has removed most of the old excuses. What remains is the decision to protect the people you love.
