Is a Handshake Deal Legally Binding in Michigan?

You agreed on the price, shook hands, and got to work. No paper, no signatures — just two people who trusted each other. Now the other side says the deal was different, or there was no deal at all.

So the question lands fast: is a handshake deal legally binding in Michigan? Short answer — often yes. A verbal agreement can be a real, enforceable contract here. But "enforceable in theory" and "provable in court" are two very different things, and a handful of deals are flat-out void unless they're in writing. Here's where the line actually sits. (This is the kind of mess we untangle in our contracts practice constantly.)

A handshake can be a real contract

Michigan does not require most contracts to be on paper. A binding agreement needs four things, and none of them is a signature:

• An offer — one side proposes clear terms
• Acceptance — the other side agrees to them
• Consideration — each side gives up something of value (money, work, a promise)
• Mutual assent — you both understood and agreed to the same deal

Hit those four and you have a contract, whether it lives in a 30-page document or a two-minute conversation in a parking lot. A handshake deal to pay a contractor $4,000 to build out your studio is, legally, a contract.

…but some deals are void unless they're in writing

This is the trap. Michigan's Statute of Frauds (MCL 566.132) says certain agreements are void — not just hard to prove, but unenforceable — unless they're written and signed by the person you're trying to hold to them. The big ones:

• Anything that can't be performed within one year — a two-year consulting arrangement, for example
• A promise to pay someone else's debt — guaranteeing a friend's or your company's obligation
• Agreements made in consideration of marriage

Real estate gets its own rule: contracts to sell or transfer land must be in writing too (MCL 566.108). And under Michigan's version of the Uniform Commercial Code, a sale of goods for $1,000 or more isn't enforceable without a writing (MCL 440.2201). So that verbal deal to buy $6,000 of inventory on a handshake? The Statute of Frauds can wipe it out.

The real problem isn't validity — it's proof

Even when a verbal contract is perfectly legal, you still have to prove it existed and prove what the terms were. With nothing in writing, it's your word against theirs. A judge can't read minds; they weigh evidence.

What helps when there's no signed contract:

• Texts, emails, and DMs confirming the terms ("$4k, done by the 15th — we good?" "yep")
• Invoices, estimates, or receipts that match what you agreed
• Payments — a deposit or partial payment shows a deal was struck
• Performance — work actually started or was delivered
• Witnesses who heard the agreement

Notice the pattern: every one of those is a record. The handshake itself proves nothing. The paper trail around it does.

Protect yourself — get it in writing (even a short one)

You don't need a lawyer-drafted contract for every deal. You need a record. After any meaningful handshake, send a confirming message: "Confirming what we agreed — I do X, you pay $Y by Z date." If they reply "yes," you've just created written evidence of the terms and, for many deals, satisfied the Statute of Frauds.

For anything bigger — a partnership, a long-term arrangement, real estate, or serious money — a real signed agreement isn't paranoia. It's the cheapest insurance you'll ever buy. The cost of writing it down is an afternoon; the cost of a "he said, she said" fight is your time, your money, and sometimes the whole deal.

When to call ELN

If a handshake deal has gone sideways — they're denying the terms, refusing to pay, or claiming there was never an agreement — don't assume you're out of luck just because nothing was signed. And if you're about to shake on something big, the smartest move is to get the terms down before the dispute, not after.
