Michigan LLC Operating Agreement: What It Is and Why You Need One

Michigan does not legally require an LLC operating agreement. But every Michigan LLC should have one — from a single-member freelance business to a multi-member real estate partnership.

What Is a Michigan LLC Operating Agreement?

An operating agreement is a legal document that defines how your LLC operates internally:

Who owns the LLC and what percentage each member holds
How profits and losses are distributed
How decisions are made and who has voting rights
What happens when a member wants to leave, sell, or dies
How the LLC is managed
What happens if the LLC dissolves

Why Michigan LLCs Need One

Michigan’s Default Rules Apply Without One

Michigan’s LLC Act contains default provisions that govern any LLC without an operating agreement. These defaults are one-size-fits-all and rarely match what members actually want — including requiring unanimous consent for decisions that could easily deadlock a business.

It Protects Your Limited Liability Status

Courts sometimes pierce the corporate veil when an LLC appears informal. A signed operating agreement reinforces that your LLC is a legitimate separate entity.

Banks Require It

Many Michigan banks ask to see your operating agreement when opening a business account or applying for a loan.

What to Include

Member names, addresses, and ownership percentages
Initial capital contributions
Management structure (member-managed vs. manager-managed)
Voting rights and thresholds
Profit and loss distribution
Process for adding or removing members
Buyout provisions
Dissolution procedures

Single-Member vs. Multi-Member

Single-member: Still matters — establishes the LLC as a real separate entity and is often required by banks.

Multi-member: Critical. Without a written agreement, Michigan’s default rules govern any dispute between members.
