Missouri’s Electronic Wills & Trusts Signing Act: What You Need to Know
Missouri has officially entered the digital era of estate planning. Effective August 28, 2025, the Missouri Electronic Wills and Electronic Estate Planning Documents Act allows residents to execute wills, trusts, powers of attorney, and healthcare directives entirely electronically — without a traditional in-person signing. The law modernizes how estate plans are created, witnessed, notarized, and stored. But electronic execution is not without legal risk, and not every situation calls for it. This guide explains exactly what the law requires, what it permits, where the dangers are, and how to decide which approach is right for you.
Missouri Electronic Wills and Electronic Estate Planning Documents Act
Effective date: August 28, 2025 | Applies to: Wills, trusts, powers of attorney, healthcare directives, and other core estate planning documents
The Act permits Missouri residents to create, sign, witness, and store estate planning documents entirely in electronic form. Witnessing may occur in person or via live real-time video. Remote online notarization (RON) is permitted for self-proving affidavits. Electronic documents have the same legal validity as paper originals when properly executed under the Act’s requirements.
Paper documents remain fully valid. The Act is an additional option — not a replacement for traditional execution. Many attorneys continue to prefer in-person signing for high-asset estates or situations involving capacity concerns or potential family disputes.
What Documents Can Be Signed Electronically?
Missouri’s law applies to the full suite of core estate planning documents. For the first time, a complete Missouri estate plan can be drafted, signed, witnessed, and stored without anyone being physically present in the same room.
- Wills — including pour-over wills that direct assets into a trust
- Revocable living trusts — and trust amendments
- Durable powers of attorney — financial decision-making authority
- Healthcare directives / living wills — end-of-life medical instruction documents
- Healthcare powers of attorney — naming a healthcare agent
- HIPAA authorizations
- Self-proving affidavits — executed via remote online notarization, streamlining probate administration later
The Four Execution Requirements Under Missouri Law
Electronic estate planning documents are only legally valid if they meet every one of the Act’s execution requirements. A document that cuts corners — using the wrong platform, skipping live witnessing, or relying on asynchronous video — is not a valid electronic will under Missouri law. It may have no legal effect at all.
The person creating the document must sign electronically — or direct another person to sign in their presence and at their direction. Electronic intent is critical: courts look at whether the person genuinely intended the document to function as their will or trust, not merely whether a digital signature exists.
Capacity and intent at the time of electronic signing are subject to the same scrutiny as paper documents — and potentially more, given the novelty of the medium and the potential for technological coercion.
Just like paper wills, electronic wills require at least two witnesses who:
- Observe the signing in real time — not from a recording
- Are physically present or electronically present via live two-way audio/video
- Sign electronically themselves, at or near the time of the testator’s signing
- Are not beneficiaries under the will (to avoid interested witness issues)
Asynchronous witnessing — watching a recording of the signing later — is not permitted under Missouri law. The witnessing must be live and contemporaneous.
“Electronic presence” under the Act means a live, real-time communication in which all parties can see and hear each other simultaneously. Think Zoom or Microsoft Teams — not email, not pre-recorded video, not a phone call without video.
- All parties must be able to see and hear each other simultaneously
- Interaction must be contemporaneous — occurring at the same time
- A phone call alone (audio only) does not satisfy the requirement
- The platform must support the identity verification requirements the law contemplates
Missouri permits remote online notarization for self-proving affidavits and certain estate planning documents. RON allows a notary public to notarize documents via live audio-visual communication and electronic signature — without physical presence.
- Notary verifies identity via knowledge-based authentication and credential analysis
- The session is typically recorded for the notary’s records
- A notarized self-proving affidavit eliminates the need for witnesses to testify in probate court, streamlining administration
- RON notaries must be commissioned in Missouri and use approved technology platforms
How Electronic Estate Plan Signing Works in Practice
When working with TrustFully, the electronic signing process follows three stages — each designed to meet Missouri’s statutory requirements while making the experience as seamless as possible for clients who prefer remote execution.
A qualified estate planning attorney drafts your will, trust, and all related documents using a secure digital platform built to meet Missouri’s statutory standards. Documents are reviewed by the client digitally before the signing session.
You sign digitally on a platform that can authenticate identity. Two witnesses join via secure live video to observe and co-sign. A remote online notary can notarize the self-proving affidavit in the same session. No office visit required.
Executed documents are stored in secure cloud storage or a qualified custodian vault. Certified paper copies — sworn under penalty of perjury to be accurate representations of the electronic original — are available for institutions and courts that require physical documents.
Electronic Document Storage — Requirements and Risks
An electronic will that cannot be produced is a will that may be presumed revoked. Missouri law requires that electronic estate planning documents remain readable, accessible, and reproducible throughout the testator’s lifetime and after death. This is one of the most practically important — and most overlooked — aspects of electronic estate planning.
The Missing Electronic Will Problem: If evidence shows that an electronic will once existed but cannot be located at death, Missouri law may presume it was revoked — just as it would with a missing paper will. Storage failures, forgotten passwords, defunct platforms, or inaccessible accounts can all result in a valid electronic will being treated as if it never existed. This is why storage strategy is not optional — it is a core part of executing an electronic estate plan properly.
Storage options under the Act and best practices for each:
- Attorney-maintained secure cloud storage — the simplest option; your attorney’s office maintains the document and provides access instructions to your successor trustee or executor
- Qualified custodian vaulting services — specialized services designed for long-term digital document storage with built-in accessibility procedures for fiduciaries after death
- Certified paper copies — the Act expressly allows a qualified custodian to certify a paper copy as a true and correct representation of the electronic original; courts must accept these certified copies even when original paper documents would normally be required
- Personal cloud storage (iCloud, Google Drive, Dropbox) — permissible but high-risk; access depends on passwords surviving the testator and family members knowing where to look
Storage failures don’t just create legal problems for the will itself — they compound the broader digital asset problem. If your electronic will is stored in an account your executor can’t access, and your executor also can’t access your financial accounts because digital credentials weren’t preserved, the estate can face significant delays.

Benefits and Risks — Electronic vs. Traditional Execution
Advantages of Electronic Execution
- Convenience — sign from home without scheduling office visits or arranging transportation
- Accessibility — ideal for elderly or disabled clients, busy parents, and rural Missouri residents far from attorneys
- Speed — execution can occur faster without coordinating schedules for an in-person meeting
- Out-of-state witnesses — family witnesses don’t need to travel; electronic presence suffices
- Time-sensitive situations — health emergencies or urgent planning needs can be addressed quickly
- Same legal validity — a properly executed electronic will is as valid as a paper original under Missouri law
- Easier updates — amendments and restatements can be executed without an in-person trip
Practical Concerns
- Platform compliance — not all e-signature tools meet Missouri’s statutory requirements; a non-compliant platform means an invalid document
- Witness procedure errors — asynchronous witnessing, missing co-signatures, or improper electronic presence can void the will
- Storage failures — a missing electronic will may be presumed revoked; storage strategy is essential
- Fraud and undue influence — digital execution can obscure coercion; courts may scrutinize capacity and intent more closely
- Technology literacy — elderly testators unfamiliar with video platforms may have difficulty executing properly, raising capacity questions
- Complex or high-asset estates — traditional in-person execution may be preferred for evidentiary strength in estates likely to face challenges
- Contested estate risk — electronic wills may face greater scrutiny in probate proceedings where family members contest the document
Electronic vs. Traditional Signing — Side-by-Side Comparison
| Factor | Electronic Execution | Traditional In-Person |
|---|---|---|
| Legal validity in Missouri | Fully valid if executed per statute | Fully valid — long-established standard |
| Witnessing | In-person or live video — either works | Physical presence required |
| Notarization | Remote Online Notarization permitted | In-person notary required |
| Convenience / accessibility | High — sign from anywhere with internet | Requires travel to office |
| Storage / retrieval risk | Medium-High — requires robust storage plan | Low — paper originals are tangible |
| Probate court acceptance | Certified paper copies accepted by Missouri courts | Original paper accepted directly |
| Contest / litigation risk | Potentially higher — novel medium, platform compliance questions | Lower — well-established evidentiary standard |
| Best for | Remote clients, time-sensitive situations, simple estates, mobility-limited clients | High-asset estates, capacity concerns, anticipated family disputes |
A DocuSign envelope or a scanned PDF with a typed signature is not a valid Missouri electronic will. The Act has specific technical requirements for electronic signatures, electronic presence, and platform compliance. A will executed on a non-compliant platform has no legal effect — it is not a valid paper will and it is not a valid electronic will. The testator’s estate would pass under intestacy as if no will existed at all.
This is why working with a qualified Missouri estate planning attorney who understands the Act’s platform requirements is essential — not optional — when pursuing electronic execution.
When Electronic Signing Makes the Most Sense
Electronic execution is a powerful tool when the situation calls for it. It is not inherently better or worse than traditional signing — it is a different option with different tradeoffs. Here are the scenarios where it is most and least appropriate:
Electronic Execution Works Well When:
- Clients live in different states — witnesses or parties who would need to travel can participate via live video
- Mobility or health limitations exist — elderly clients, those with disabilities, or anyone recovering from illness can execute without leaving home
- Scheduling is genuinely difficult — busy professionals and parents with demanding schedules benefit from the flexibility of remote signing
- Time sensitivity exists — a health emergency or urgent planning need can be addressed immediately without waiting for an in-person appointment to be scheduled
- Rural Missouri residents — those far from estate planning attorneys gain easier access to quality legal counsel without long travel
- Straightforward estate plans — standard revocable trust plans, simple wills, and powers of attorney are well-suited to electronic execution
Traditional In-Person Signing May Be Preferable When:
- Capacity is a concern — for elderly testators or those with cognitive impairment, in-person execution provides stronger evidentiary documentation of testamentary capacity
- Family disputes are anticipated — where beneficiaries are likely to contest the will, traditional in-person execution with detailed attorney notes creates a stronger evidentiary record
- High-asset or complex estates — for estates with significant assets, business interests, or sophisticated planning, the additional evidentiary protection of in-person execution is often worth the modest inconvenience
- Technology access or literacy is limited — a testator who cannot comfortably operate video conferencing should not be forced into an electronic signing process
- Undue influence risk exists — situations involving recent caregivers, new relationships, or other potential influence concerns are better handled with in-person, face-to-face execution where the attorney can directly observe the dynamic
At TrustFully, both options are available. Many clients use a hybrid approach — a video consultation to discuss the plan and review documents, followed by either an electronic signing session or an in-person appointment depending on the client’s preference and situation.
Does This Replace Traditional Estate Planning? No.
Paper wills and trusts remain fully valid and widely used. Many estate planning attorneys — particularly for high-asset or litigation-risk estates — still prefer in-person execution for its evidentiary strength. The Missouri Electronic Wills Act creates an additional valid option, not a mandate to go digital. The right execution method depends on the client’s circumstances, the complexity of the estate, and the legal risk profile involved.
What the Act does change is access: Missourians who previously couldn’t easily work with a qualified estate planning attorney because of geography, mobility, or scheduling constraints can now get a legally sound estate plan without those barriers.
