Are Electronic Signatures Legally Binding in Michigan?

You never touched a pen. You opened a link on your phone, tapped "Adopt Signature," clicked "Finish," and went back to your day. Six months later, the deal goes sideways, and someone asks the question that suddenly matters: did you actually sign anything?

In most cases, yes. Electronic signatures are a normal, enforceable way to sign contracts in Michigan. But "electronic" isn't magic, and it isn't a loophole either. Whether you're signing a vendor agreement or sending one out, our contracts practice can help you make sure the signature holds up when it counts.

The short answer: yes, with conditions

Two laws do most of the work here.

Michigan's Uniform Electronic Transactions Act (MCL 450.831 and following), adopted in 2000, says that a record or signature can't be denied legal effect just because it's electronic. If a law requires a signature, an electronic signature satisfies it. If a law requires a writing, an electronic record generally satisfies it.

The federal E-SIGN Act (2000), found at 15 U.S.C. § 7001 and following, sets a similar baseline for transactions in interstate commerce.

Put simply, the format isn't the problem. A contract doesn't become weaker because it lives in a PDF instead of a filing cabinet.

What counts as an "electronic signature"

More than most people think. Under the Michigan act, an electronic signature is broadly an electronic sound, symbol or process attached to or logically associated with a record and adopted by a person with the intent to sign it.

That can include:

• A signature drawn with a finger or stylus on a screen
• A typed name in a signature block
• Clicking "I Agree" or "Accept" on a checkout or sign-up page
• Signing through a platform like DocuSign, Adobe Sign, or Google Workspace
• In some situations, a typed name at the bottom of an email

The key phrase is intent to sign. The technology matters less than whether the person meant to adopt the record as their own.

Both sides have to agree to do it electronically

The Michigan act applies to transactions where the parties have agreed to conduct business by electronic means. That agreement doesn't have to be a formal clause. Courts look at the context and the parties' conduct.

If you've been negotiating by email, exchanging drafts as PDFs and signing through an e-signature link, that conduct usually shows agreement. It gets murkier when one side has never done business electronically, or when a contract specifically requires "wet ink" original signatures. If your agreement says signatures must be original and handwritten, don't assume a click will do.

Where e-signatures run into trouble

The law makes electronic signatures valid. It doesn't make every electronic signature provable. Most disputes aren't about whether e-signatures are allowed. They're about whether this signature belongs to this person.

Attribution. The Michigan act treats a signature as the act of a person if it can be shown that it was, which can be proven in any manner, including the efficacy of a security procedure. That's where e-signature platforms earn their fee. A completion certificate showing the signer's email, IP address, time stamps and authentication steps is far stronger evidence than a pasted image of a signature.

The "my assistant signed it" problem. If someone else had access to your email or account and clicked through, you may have arguments about authority. You may also have a mess, because agency rules and your own conduct afterward, like paying invoices under the agreement, can still bind you.

Altered documents. A strong e-signature platform locks the document after signing and flags changes. A Word file passed back and forth by email doesn't. If the version you signed and the version they're holding don't match, the audit trail decides a lot.

Clickwrap versus browsewrap. Online terms come in two flavors. Clickwrap requires you to affirmatively click "I agree" before continuing. Browsewrap puts a link to terms somewhere on the page and says that using the site means you agree. Courts across the country tend to enforce clickwrap when the terms were reasonably presented, and they're more skeptical of browsewrap when the user had no real notice. If your business relies on online terms, the design of the checkout page is a legal decision, not just a design one.

Documents that need extra care

Electronic signatures cover most business contracts, but not everything. Both the Michigan act and E-SIGN carve out certain categories. The most familiar are wills and testamentary trusts. Some consumer notices and other specialized documents have their own rules, and some recording offices and agencies have their own requirements for what they'll accept.

A few practical flags:

• Real estate. Michigan's statute of frauds requires certain real estate deals to be in a signed writing. Electronic signatures can satisfy that, but deeds and recorded documents often run into notarization and county recording requirements. Check before you assume.
• Notarized documents. Michigan does allow electronic and remote notarization under specific rules, but a notarized document isn't the same as an e-signed one. If notarization is required, follow the notary rules.
• Consumer transactions. E-SIGN has specific consent and disclosure requirements before businesses can deliver certain required consumer notices electronically. If you sell to consumers, that process deserves a look.

What it looks like in practice

Here's the shape of a common dispute, with made-up details.

A Detroit marketing agency sends a new client a six-month services agreement through an e-signature platform. The client's operations manager signs it from a company email. Three months in, the client stops paying and says the manager wasn't authorized to sign and never really "signed" anything, since it was just a click.

The agency pulls the platform's completion certificate: the email address, the time, the IP address, the authentication step, and the fact that the client opened the document twice before signing. It also has three paid invoices and a string of emails approving the agency's work under that agreement.

The "it was just a click" argument is weak. The authority question is a real one, but the client's conduct after signing makes it much harder. The agency still has a dispute to work through, but it's arguing from a strong record. Compare that to a deal where the only evidence is a forwarded PDF with a pasted signature image. Same law, very different starting point.

If you're the one sending the contract

• Use a real e-signature platform for anything that matters. The audit trail is the point.
• Send it to the right person. Confirm that the signer has authority to bind the company, especially for larger deals. Ask for a title, not just a name.
• Include a counterparts and electronic signature clause. One sentence stating that the parties agree to sign electronically and that electronic signatures are as binding as originals removes an argument.
• Keep the final executed version. Store the completed document and its certificate together, where your team can find them in two years.
• Don't let email undo the contract. A casual "sure, we can change that" email may be argued as a modification. If your contract requires amendments to be signed, keep amendments formal.

If you're the one signing

• Read before you click. An electronic signature binds you just as a pen would. "I didn't read it" is rarely a defense, on paper or on a screen.
• Download your copy. Don't rely on the other side's platform to keep it for you.
• Check what's incorporated. Clicking "I agree" often accepts terms that live on a separate web page. Those linked terms can include auto-renewal and entire agreement language that changes the deal.
• Don't share your login. If someone else can sign as you, someone else can bind you.

Signed electronically, but no signature at all?

Sometimes there's no formal signature, just emails and performance. That raises a different question: whether a contract formed at all, and whether any writing requirement is satisfied. We cover that in whether a handshake deal is binding in Michigan. If you're looking for a way out of a contract you did sign, start with how to get out of a contract in Michigan.

When to call ELN

Call us if you're setting up an electronic signing process for your business, if a counterparty is claiming an e-signed contract doesn't bind them, or if you're being held to a click you don't remember making.

No one can promise how a dispute ends, but the earlier the record is reviewed, the more options you usually have.
