LLC Merger Approval and Filing Requirements in Michigan

At a glance

Michigan answers the merger question three times in one article. Article 7 of the Limited Liability Company Act, Act 23 of 1993, runs from § 450.4701 to § 450.4706, and which section governs depends entirely on who the other constituent is: another domestic LLC, a foreign LLC, or a business organization of any other kind. The approval default is the same in each, a unanimous vote of the members entitled to vote unless the operating agreement provides otherwise, and so is the consequence of changing it. Michigan has no appraisal statute for LLC members. What it has instead is a withdrawal right that exists only because the operating agreement lowered the vote, which makes a drafting choice in the operating agreement, rather than the merger statute, the thing that decides whether a dissenting member is paid.

Requirements one by one

The governing act and the three routes

Article 7 of the Michigan Limited Liability Company Act is the merger article, and the compiled law numbers it § 450.4701 through § 450.4706 with § 450.4705a inserted between the fifth and sixth. The act speaks only of merger; consolidation is not a separate statutory transaction, and there is no separate vocabulary for a merger of equals. What the act does divide on is the identity of the other constituent. § 450.4701 handles a merger of two or more domestic limited liability companies. § 450.4705 handles a merger in which one or more foreign limited liability companies take part. § 450.4705a handles a merger with a business organization, which the act defines broadly enough to cover almost any other enterprise. The routing is not left to choice: § 450.4705a(2) provides that if all of the business organizations in a merger with one or more domestic limited liability companies are foreign limited liability companies, the merger must comply with § 450.4705 and not § 450.4705a. A practitioner therefore identifies the counterparties first and the governing section second. Conversion is a different transaction that the act places elsewhere, and § 450.4206(8) refers to a business organization into which a domestic limited liability company has converted under section 708 of the act; it is outside this answer.

Who can be a party

The domestic route is the narrowest. § 450.4701(1) permits two or more domestic limited liability companies to merge, and nothing more. § 450.4705(1) opens the door to one or more foreign limited liability companies merging with one or more domestic limited liability companies, on two conditions: the merger must be permitted by the law of the jurisdiction under whose law each foreign constituent company is organized and each foreign constituent company must comply with that law in effecting the merger, and each domestic constituent company must comply with § 450.4701 through § 450.4703. That is a deference rule of the familiar kind, and it means a Michigan LLC cannot rescue a transaction the counterparty jurisdiction forbids. The cross-form route is the widest. § 450.4705a(1)(a) defines a business organization as a domestic or foreign corporation, a domestic or foreign nonprofit corporation, a limited partnership, a general partnership, a telephone corporation formed under 1883 PA 129, or any other type of domestic or foreign business enterprise, incorporated or unincorporated, and excludes only a domestic limited liability company, which the companion definition of entity reaches instead. § 450.4705a(3) then permits the merger where the law of each constituent business organization's jurisdiction allows it and that organization complies, each foreign constituent transacting business in Michigan complies with Michigan law, and each domestic LLC complies with the section. Either side may survive; § 450.4705a(10) expressly addresses a foreign business organization as the surviving entity.

What the plan must say

§ 450.4701(2) gives the plan of merger four required items for a domestic merger. The plan must set forth the name of each constituent company and the name of the surviving company; the terms and conditions of the proposed merger, including the manner and basis of converting the membership interests in each limited liability company into membership interests in the surviving company, or into cash or other property, or into a combination of those; a statement of any amendment to the articles of organization of the surviving company to be effected by the merger, or any restatement of the articles, or a statement that no changes are to be made; and other provisions with respect to the proposed merger that the constituent companies consider necessary or desirable. The act does not say in terms that the plan must be in a record, and it prescribes no form, but § 450.4703(1) presupposes an approved plan before a certificate may be executed, and the certificate must carry forward two of the plan's items. A cross-form merger uses a slightly longer list. § 450.4705a(4) requires each domestic limited liability company to prepare a plan of merger containing the name of each constituent entity, the name of the surviving entity, the street address of the surviving entity's principal place of business, and the type of organization of the surviving entity, and it widens the consideration to ownership interests or obligations of an entity that is not a party to the merger, reflecting that the interests being converted may be shares or partnership interests rather than membership interests.

Member approval and how far the operating agreement can move it

The threshold is in § 450.4702(1). A plan of merger shall be submitted to the members of each constituent company for approval, and a unanimous vote of the members entitled to vote in each constituent company is required to approve a merger, unless an operating agreement of a constituent company provides otherwise. § 450.4705a(5) repeats that default for a cross-form merger. Two features of the sentence do the work. The denominator is the members entitled to vote, not all members, so a non-voting class is excluded from the count rather than given a veto. And the override is unqualified: the act states no floor, no majority-in-interest fallback, no separate class vote, and no grandfather date tied to the date of formation. An operating agreement may therefore set the merger vote at a bare majority, at a supermajority, or at the consent of a single designated member, and Michigan does not police the choice through the threshold. It polices it through the consequence instead, because the withdrawal right in § 450.4702(2) and § 450.4705a(6) exists only where the operating agreement has lowered the vote below unanimity. Article 7 requires no manager approval step at all, which distinguishes Michigan from the acts that route a merger through the governing authority first. Each foreign or other-form constituent approves under its own governing law; § 450.4705(1)(a) and § 450.4705a(3)(a) make that compliance a condition of the merger rather than a Michigan procedure to be documented.

Meetings, consents and the liability that is not consented to

Article 7 is silent where many LLC acts are detailed. It prescribes no meeting and no notice period, sets no minimum or maximum notice, lists no notice contents, supplies no deemed-delivery rule, provides no waiver mechanism, and offers no written-consent or all-member-signature alternative to a vote. § 450.4702(1) says only that a plan of merger shall be submitted to the members of each constituent company for approval, which leaves the mechanics to the operating agreement and to the act's general provisions on member voting. Michigan also lacks the new-personal-liability consent that the uniform acts use. A member who will become personally liable for the obligations of the survivor gets no separate statutory veto on that ground, and the act does not require a consent in a record from such a member. What the act protects instead is the position before the merger. § 450.4705a(9)(d) provides that the surviving entity has all of the liabilities of each constituent entity and that the section does not affect the liability, if any, of a person that was an obligated person with respect to a merging entity for acts or omissions that occurred before the merger, with obligated person defined in § 450.4705a(1)(d) as a general partner, a partner of a general partnership, or a comparable owner generally liable for an enterprise's obligations. A member who objects to the merger relies on unanimity under § 450.4702(1) while it lasts, and on withdrawal under § 450.4702(2) once the operating agreement has taken unanimity away.

The certificate of merger, signers and fees

The public record is a certificate of merger, and Michigan files it differently from most states. § 450.4703(1) requires the certificate to be executed as provided in § 450.4103 and filed on behalf of each constituent company, not by the survivor alone. Its contents are the names of each constituent company and of the surviving company and the articles-of-organization statement, both carried over from § 450.4701(2); a statement that the plan of merger has been approved by the members of the constituent company in accordance with § 450.4702(1); a statement of any assumed names of merging limited liability companies transferred to the surviving company as authorized by § 450.4206(6), specifying each transferred name and the company it came from; and the effective date of the merger if later than the date the certificate is filed. The certificate may also designate assumed names to be treated as newly filed under § 450.4206(7), so the assumed-name housekeeping is done inside the merger filing rather than by a separate application. § 450.4705a(7) sets the parallel list for a cross-form merger. Execution is governed by § 450.4103(2): a manager signs if management is vested in one or more managers, at least one member signs if management remains in the members, or any authorized agent of the company may sign, and the document must state the name of the person signing and the capacity in which that person signs beneath or opposite the signature. The filing goes to the administrator under § 450.4104, and § 450.5101(1)(j) sets the fee for a certificate of merger under article 7 at $100.00. A foreign limited liability company that survives files separately under § 450.5005. § 450.4104(7) permits the administrator to require a prescribed form.

Effective date, abandonment and correction

§ 450.4703(2) makes the certificate of merger effective in accordance with § 450.4104, and § 450.4104(6) supplies the operative sentence: a document filed under that section is effective at the time it is endorsed unless a subsequent effective time is set forth in the document that is not later than 90 days after the date of delivery. Ninety days after delivery is therefore the outer limit on a deferred closing, and the matching content field is in § 450.4703(1)(d), the effective date of the merger if later than the filing date. Article 7 contains no plan-amendment provision, so it specifies no change that triggers a fresh member vote; an amendment is a matter for the plan and the operating agreement. Abandonment is express and well built. Under § 450.4706(1), unless a plan of merger provides otherwise, at any time before the effective date of a certificate of merger the merger may be abandoned in accordance with the procedure set forth in the plan of merger or, if the plan sets out no procedure, by the unanimous vote of the members entitled to vote in each domestic limited liability company that is a constituent entity, unless an operating agreement provides otherwise. Where a certificate has already been filed, § 450.4706(2) requires a certificate of abandonment within 10 days after the abandonment but not later than the effective date of the certificate of merger, which costs $10.00 under § 450.5101(1)(k). A filing that was an inaccurate record or was defectively executed is repaired under § 450.4106 by a certificate of correction, $25.00 under § 450.5101(1)(a), which takes effect as of the original filing date except as to a person who relied upon the inaccurate portion and was adversely affected by the correction.

What happens to property, debts and lawsuits

§ 450.4704 lists the effects, and they take hold when the merger takes effect rather than on filing. Every other constituent company merges into the surviving company and the separate existence of every constituent company except the survivor ceases. All property, real, personal and mixed, all debts due on whatever account, including promises to make contributions, all other choses in action, and any other interest of or belonging to or due to each constituent company are vested in the surviving company without further act or deed and without reversion or impairment, so no deed or assignment is needed and no reverter survives. The surviving company may use the name and the assumed names of any constituent company if the filings required under § 450.4206(6) and (7) are made. The survivor has all of the liabilities of each constituent company. A proceeding pending against any constituent company may be continued as if the merger had not occurred, or the surviving company may be substituted in the proceeding for the company whose existence ceased, which is a permission rather than an automatic substitution. The articles of organization of the surviving company are amended to the extent provided in the certificate of merger, so the certificate does the amending. Membership interests are converted into membership interests in the survivor, cash, or other property as provided in the plan of merger. § 450.4705a(9) restates the list for a cross-form merger in the vocabulary of entities and ownership interests and adds the obligated-person carve-out. What the statute does not promise is continuity of contracts, licences, permits or tax status, and registrations move only so far as the assumed-name provisions in § 450.4206 carry them.

Fair value instead of appraisal, creditors and a foreign survivor

Michigan gives an LLC member no appraisal or dissenters right. The act contains no appraisal provision at all, and the only fair-value payment in it is conditional on the operating agreement. § 450.4702(2) provides that if an operating agreement of a constituent company provides for approval of a merger by less than unanimous vote of members entitled to vote and the merger is approved, a member that did not vote in favor of the merger may withdraw from the limited liability company and receive, within a reasonable time, the fair value of the member's interest in the limited liability company, based upon the member's share of distributions as determined under § 450.4303. That cross- reference is the measure, and it matters: § 450.4303(1) allocates distributions as an operating agreement provides and, absent an allocation, on and after July 1, 1997, in equal shares to all members. The default yardstick for fair value is therefore a per-capita share rather than a share proportionate to contributions. The cross-form version in § 450.4705a(6) is narrower by one phrase, reaching a member that voted against the merger, while § 450.4702(2) reaches a member that did not vote in favor, which also covers an abstention or a failure to vote. Where unanimity survives in the operating agreement there is no payment right at all, because a merger cannot be approved over a member's objection. Creditors are protected by succession under § 450.4704 rather than by any notice or claims procedure. § 450.4705(3) makes the surviving company liable for, and subject to service of process in a proceeding in Michigan for the enforcement of, any obligation of a domestic constituent company, including any obligation to a member who has dissented from the merger and withdrawn under § 450.4702(2), and § 450.4705a(10) says the same where the survivor is a foreign business organization. A foreign limited liability company authorized to transact business in Michigan that survives a merger must also file, not later than 30 days after the merger becomes effective, a certificate issued by the proper officer of its jurisdiction of organization attesting to the occurrence of the merger under § 450.5005(2), at $10.00 under § 450.5101(1)(p).

Short-form routes and special entities

Michigan has no short-form merger. Article 7 provides no parent-subsidiary route, no ownership-threshold shortcut, no certificate of ownership and merger, and no substituted filing, so a merger between a parent and a wholly owned subsidiary proceeds under § 450.4701 through § 450.4703 like any other, unanimous default vote included. The act's other statutory route out of the LLC form is conversion, which § 450.4206(8) locates at section 708 and which this survey does not cover. The one express entity boundary inside the merger rules is professional practice. § 450.4910 provides that a professional limited liability company may merge only with other limited liability companies whose members and managers are licensed persons permitted to be members or managers under that article, or other entities that are licensed persons or whose shareholders, partners, or other owners, members, or managers are licensed persons permitted to be members or managers under that article. That is a closed circle of like-licensed counterparties, and § 450.4902 fixes its width by defining a licensed person as an individual licensed or otherwise legally authorized to practise a professional service, or a corporation, partnership, or limited liability company all of whose owners, members and managers are licensed persons. Nonprofit corporations, by contrast, are inside the permitted counterparties rather than carved out: § 450.4705a(1)(a) lists them and § 450.4705a(1)(c) defines a nonprofit corporation by the law of the jurisdiction in which it was formed, so charitable-asset and regulatory restrictions reach the transaction through that entity's own law under § 450.4705a(3)(a). Banking, insurance, utility, securities, antitrust and tax approvals stay outside this survey.
