What a Limited Partnership Is and Who It Fits
A limited partnership, or LP, is a business with two kinds of owners. The general partner runs the show — signs contracts, makes decisions, and carries unlimited personal liability for the partnership's debts. The limited partners are investors. They contribute money or property, share in the profits, and their exposure is capped at what they put in, as long as they stay out of day-to-day control. That trade — capital without management, management without capital protection — is the whole point of the structure.
Michigan governs limited partnerships under the Michigan Revised Uniform Limited Partnership Act, found in Chapter 449 of the Michigan Compiled Laws. An LP legally exists once its Certificate of Limited Partnership is filed and accepted by the state. Filing is handled by the Department of Licensing and Regulatory Affairs (LARA), through its Corporations, Securities & Commercial Licensing Bureau — not the Secretary of State, which is a detail that catches people off guard if they assume Michigan works like most other states.
Where the LP structure earns its keep
The classic use is a venture with a clear split between the person running it and the people funding it. Real estate holding partnerships are a common example: one general partner manages a building or a portfolio, while passive investors hold limited-partner interests and collect distributions without touching the day-to-day. Family investment vehicles, film and entertainment projects, and small private funds also lean on the LP form for the same reason — it lets money come in without handing over control, and it caps the investors' downside.
An LP is not the right tool for a solo operator or for co-owners who all want to manage. A single owner is better served by an LLC. Partners who all want a hand on the wheel and all want liability protection usually look at an LLC or, for licensed professionals, an LLP. The LP shines specifically when the roles are meant to be unequal by design.
The general partner carries the risk
The defining feature of a limited partnership is that the general partner's liability is not limited. If the partnership can't pay a judgment or a debt, the general partner's personal assets are reachable. This is why many limited partnerships name a corporation or an LLC as the general partner rather than an individual — it puts a liability shield around the one role that would otherwise be fully exposed. That structuring decision is worth discussing with an attorney before you file, because it changes who signs and how the Certificate reads.
How Michigan Treats a Limited Partnership Once It Is Formed
Filing the Certificate of Limited Partnership does two things at once. It creates the public record that the LP exists, and it draws the line between general and limited partners that the liability rules depend on. Michigan processes the filing through the LARA Corporations Division and its MiBusiness Registry portal.
The limited partners' shield — and its limits
A limited partner's liability is generally capped at their capital contribution, but that protection depends on staying passive. Michigan's LP law lets a limited partner lose the shield if they cross into control of the business — participating in management the way a general partner would. The statute carves out a list of "safe harbor" activities a limited partner can do without being treated as a general partner, such as consulting with the general partner, voting on major matters, or being an officer of a corporate general partner. Step outside those lines and a limited partner can be exposed to creditors who reasonably believed they were dealing with a general partner. The lesson: keep the roles clean and put them in writing.
Pass-through taxation
For federal tax purposes an LP is treated as a partnership by default. The partnership itself pays no federal income tax. It files an informational return on Form 1065 and issues each partner a Schedule K-1 reporting their share of income, deductions, and credits, which each partner then reports on their personal return. Michigan follows the pass-through model, so partnership income flows to the partners' individual Michigan returns rather than being taxed twice. This keeps the tax picture close to how the partners already split the economics of the deal.
Keeping the record current
An LP's Certificate has to stay accurate over time. If the general partners change, if a new general partner is admitted, or if key facts on the Certificate shift, Michigan expects an amendment to be filed so the public record reflects reality. We cover what stays true year to year on the annual requirements page.
The Resident Agent Requirement
Every Michigan limited partnership must appoint and maintain a resident agent. Michigan uses the term "resident agent" where many states say "registered agent," but the job is identical: the resident agent is the official contact who accepts service of process — lawsuits and legal notices — and receives official mail from the state on behalf of the partnership.
What the resident agent must satisfy
- A registered office with a physical street address in Michigan. A post office box on its own does not satisfy the requirement.
- Availability during normal business hours so legal documents can be delivered and received reliably.
- A genuine willingness to serve, and a habit of forwarding what arrives to the partners promptly.
A general partner can serve as the resident agent if they have a Michigan street address and are consistently available during business hours. Many partnerships instead use a commercial resident agent service. The reasoning is practical: it keeps a partner's home address out of the public LARA record, it guarantees someone is present to accept a summons even when the general partner is traveling or in a meeting, and it centralizes state correspondence so nothing slips through the cracks. Our resident agent page walks through the requirement in full.
What Mainstay Filing Does for Your Limited Partnership
We prepare and submit your Certificate of Limited Partnership with LARA so you are not learning the MiBusiness Registry interface under deadline pressure or second-guessing whether you completed the filing correctly. You give us the partnership's information — its name, its Michigan office, the general and limited partner details the state requires, and your resident agent choice — and we assemble the Certificate, file it, and return the state-stamped confirmation once LARA processes it.
We also provide resident agent service, so a professional Michigan address sits in the public record instead of a partner's home, and there is always someone available to accept legal documents. If the general partners change down the road, we can prepare and file the amendment so the Certificate stays accurate.
What we are not
We are a filing service, not a law firm or an accounting firm. We do not draft your limited partnership agreement, advise on how partners should split profits, or give tax opinions. Those conversations belong with an attorney and a CPA — especially for an LP, where the general-partner liability question and the limited-partner control rules have real consequences. What we handle is the state-facing paperwork: getting the LP formed correctly and keeping the record in good standing so you can concentrate on the venture itself.
Frequently asked questions
What is the difference between a general partner and a limited partner in a Michigan LP?
The general partner manages the business and carries unlimited personal liability for the partnership's debts. Limited partners contribute capital, share in profits, and have liability capped at what they invested — as long as they stay out of day-to-day management. A Michigan LP needs at least one of each. Many LPs use a corporation or LLC as the general partner to shield the person behind that role.
Do I file my Michigan limited partnership with the Secretary of State?
No. Business entity filings in Michigan go through the Department of Licensing and Regulatory Affairs (LARA), specifically its Corporations, Securities & Commercial Licensing Bureau — not the Secretary of State. The Certificate of Limited Partnership is submitted through the MiBusiness Registry portal.
Does a Michigan LP need a resident agent?
Yes. Every Michigan limited partnership must appoint and maintain a resident agent with a registered office at a physical Michigan street address. The agent accepts service of process and official state mail. A general partner can serve, or you can use a commercial resident agent service. A P.O. box alone is not acceptable.
How is a Michigan limited partnership taxed?
By default, as a partnership. The LP files a federal informational return on Form 1065 and issues each partner a Schedule K-1. The partnership pays no federal income tax itself; each partner reports their share on their personal return. Michigan follows the pass-through approach, so partnership income flows to the partners' individual Michigan returns.
Can a limited partner lose their liability protection?
Yes. A limited partner's protection depends on staying passive. Michigan's LP law lets a limited partner be treated like a general partner — and lose the liability cap — if they participate in control of the business beyond the statute's list of safe-harbor activities. Keeping the general and limited roles clean and documented in the partnership agreement is how you preserve the shield.
What document creates a Michigan limited partnership?
The Certificate of Limited Partnership, filed with LARA. Once the state accepts it, the LP legally exists. This is different from the limited partnership agreement, which is the private contract among the partners and is not filed with the state.
