What Is the Michigan Electronic Signatures Act?

The Michigan Electronic Signatures Act — more precisely, Michigan’s Uniform Electronic Transactions Act (UETA), codified at MCL 450.831 through 450.849 — makes an electronic signature legally equivalent to a handwritten one, provided the parties agreed to transact electronically, the signer intended the electronic mark to serve as their signature, the signature can be attributed to that person, and the record is kept in a form that stays accurate and accessible.¹ The federal Electronic Signatures in Global and National Commerce Act (E-SIGN Act), 15 U.S.C. § 7001, reinforces those protections for transactions touching interstate commerce and generally defers to the state UETA so long as Michigan’s law does not cut back on electronic signature rights.²

What Counts as an Electronic Signature

Michigan defines an electronic signature broadly: any electronic sound, symbol, or process attached to or logically associated with a record and executed or adopted by a person with the intent to sign.³ A typed name at the end of an email can qualify. So can a finger-drawn signature on a tablet, a click on an “I Accept” button, or a cryptographic digital signature backed by a certificate authority. The technology matters less than whether the signer meant the action to serve as their signature.

When the Act Applies: Consent to Transact Electronically

The UETA only applies where all parties have agreed to conduct the transaction electronically. The statute does not demand a formal written opt-in; agreement can be inferred from the context and surrounding circumstances, including the parties’ conduct.⁴ Two businesses that have been exchanging electronically signed purchase orders for months have, through their conduct, agreed to transact that way.

Agreeing once does not lock a party in forever. The statute preserves the right to refuse electronic means for future transactions, and that right cannot be waived by agreement.⁴ A customer who signed one contract electronically has not consented to receive every future notice that way.

Documents You Still Cannot Sign Electronically

The UETA carves out two categories. It does not apply to wills, codicils, or testamentary trusts, which still require a traditional wet-ink signature. It also excludes most transactions governed by Michigan’s Uniform Commercial Code. The exception is narrow: electronic signatures are allowed for UCC sales of goods (Article 2), leases of goods (Article 2A), and certain provisions in sections 1206 and 1306. Negotiable instruments, secured transactions, and other core UCC areas have to meet the UCC’s own signature and record-keeping rules.³

The federal E-SIGN Act layers on additional exclusions. Court orders, cancellation notices for utility services and insurance, notices of default or foreclosure, and documents in family law matters such as adoption and divorce fall outside its reach. If your document sits in any of these categories, verify the specific signature requirements before going digital.

Proving the Signature Was Really Theirs

An electronic signature is only useful if you can tie it to a specific person. Under Michigan law, an electronic record or signature is attributed to a person if it was their act, and that act can be shown in any manner, including by proof that a security procedure was in place to verify the signer’s identity.⁵

“Any manner” means courts look at the full context. Basic methods include requiring login credentials or sending a verification email. Stronger approaches use multi-factor authentication: a password plus a code sent to a mobile device, or biometric verification such as a fingerprint scan. Digital signatures built on public key infrastructure (PKI) go further still. A trusted certificate authority issues a digital certificate tied to the signer, and any alteration to the document after signing invalidates the certificate. The more sensitive the transaction, the more robust the authentication method should be.

Routine purchase orders rarely draw a challenge. Disputes tend to surface around employment agreements, insurance beneficiary changes, and real estate deals, where someone has a financial motive to deny signing. For those transactions, a signing platform that captures a detailed audit trail is worth the cost.

Keeping the Record

Michigan’s UETA requires that electronically stored records meet two conditions: they must accurately reflect the information as it existed when the record was finalized, and they must stay accessible for later reference.⁶ An electronic copy that meets both standards satisfies any Michigan requirement to keep an original. An electronic image of both sides of a check is enough for check retention.

These rules also satisfy evidentiary and audit requirements unless a later-enacted Michigan law specifically prohibits electronic storage for a particular purpose, and state agencies can impose additional retention standards in their own jurisdictions.⁶ If you work in a regulated industry, check whether your agency has supplemental rules. Using a third-party storage service is fine, but the legal obligation stays with you. If the service loses the records or the format becomes unreadable, that is your problem.

Getting an Electronic Signature Into Court

Michigan Rule of Evidence 901 requires authentication before any document can be admitted. The party relying on an electronic signature must produce enough evidence to support a finding that the signature is what they claim it is.⁷ Michigan’s administrative code adds that electronic evidence cannot be excluded solely because it is electronic.⁸

What satisfies the authentication threshold depends on the circumstances. Courts weigh metadata, audit trails, and the security protocols used during signing. A strong audit trail usually records when the document was sent, opened, and signed, along with the signer’s email address, IP address, and any unique identifiers. Some platforms also capture device information and geographic location. The more comprehensive the trail, the harder it becomes for a signer to credibly deny the signature. In Zulkiewski v. American General Life Insurance Co. (2012), the Michigan Court of Appeals examined an electronic beneficiary change on a life insurance policy and affirmed attribution of the electronic action to the account holder based on the insurer’s security process, even though the appellants argued the process allowed forgery.

Extra Rules for Consumer Transactions

When a law requires that information be provided to a consumer in writing, sending an electronic version is not enough on its own. The federal E-SIGN Act imposes a disclosure process that sits on top of the UETA in consumer-facing transactions. Before obtaining electronic consent, the business has to give the consumer a clear statement covering several points:²

Right to receive records on paper or in non-electronic form.
How to withdraw consent to electronic delivery, including any fees or consequences.
Whether consent covers only the current transaction or a broader category of future records.
The hardware and software needed to access and store the electronic records.
How to obtain a paper copy after consenting, and whether a fee applies.

The consumer must then consent electronically in a way that demonstrates they can actually access the format being used. If the business later changes its technology in a way that could block access, it has to disclose the new requirements and obtain fresh consent.² Skipping a step can undermine the enforceability of the electronic record.

When Notarization Is Also Required

A document that needs an electronic signature often needs notarization too, and the UETA does not cover that side of the process. Michigan permits remote online notarization under the Michigan Law on Notarial Acts (MiLONA), with its own requirements for approved audiovisual platforms, identity proofing, recording consent, journaling, and a 10-year retention period for both the journal and the recording.⁹ If your document requires a notary, make sure your workflow meets MiLONA separately rather than assuming the e-signature platform alone is sufficient.

What Happens If the Signature Fails These Requirements

A signature that fails Michigan’s requirements can collapse the agreement it was meant to form. If authentication breaks down or consent to electronic dealing was never properly established, a court may conclude that no binding contract exists. The party trying to enforce the agreement generally bears the burden of proving the signature is valid, so a weak audit trail or missing consent documentation starts them at a disadvantage.

The consequences reach beyond the contract. In regulated industries like healthcare, finance, and real estate, inadequate authentication or record-keeping can trigger penalties from licensing agencies. Government offices and financial institutions may refuse to recognize improperly executed electronic documents, stalling loan closings, licensing applications, and regulatory filings. For consumer-facing businesses that skip the E-SIGN Act’s disclosure steps, a consumer may successfully argue the electronic record does not satisfy the legal requirement to provide information “in writing,” leaving the business without proof it met its obligations.² A forged or fraudulently attributed electronic signature can also expose the responsible party to criminal liability for forgery or identity theft under Michigan law.
