LLC Merger Approval and Filing Requirements in Delaware

At a glance

Requirements one by one

The agreement selects both the route and its limits

Current § 18-209(b) lets a domestic LLC combine with another Delaware LLC or with an “other business entity” from Delaware, another state, the United States, or a foreign jurisdiction. Section 18-209(a)'s definition is broad enough to include corporations, trusts, associations, REITs, and general or limited partnerships.

The freedom is not mandatory. Section 18-209(h) permits the LLC agreement to remove the company's power to merge or consolidate.

Ordinary agreement content is deliberately not prescribed

Section 18-209 requires an agreement of merger or consolidation but supplies no enumerated minimum terms for the ordinary route. It does state the available interest outcomes: cash, property, rights, securities, survivor or third-entity interests, continuation, or cancellation.

The agreement or short-form plan can amend or replace the survivor's LLC agreement at effectiveness. A public certificate can likewise carry formation- certificate amendments or, for a new Delaware LLC created by consolidation, attach its formation certificate. 6 Del. C. § 18-209(c)(4)-(5), (f).

Approval and procedure start with the LLC agreement

If the LLC agreement is silent, members owning more than 50% of all members' current profit interests approve. Under § 18-302(d), the same minimum may act without a meeting, prior notice, or a vote through writing, electronic transmission, or another lawful means. Section 18-302(c) leaves meeting notice, waiver, quorum, record dates, and proxies to the LLC agreement rather than supplying a fixed statutory timetable.

The merger provisions state no separate consent requirement for a member who would gain personal liability. That question therefore cannot be answered from the default vote alone; the resulting entity's law, agreement terms, and the member's own undertakings still require review.

The survivor files a detailed certificate, not the private agreement

The survivor or resulting entity files the Certificate of Merger or Consolidation with the Secretary of State. Its nine items identify every constituent and the survivor, confirm approval and execution, handle formation- certificate changes, give any certain delayed time, and state where the private agreement is kept and that interest holders may request it without cost.

If a Delaware LLC survives or results, one or more authorized persons execute for it. A compliant agreement containing the certificate's required information may be filed instead. 6 Del. C. § 18-209(c), (e).

Amendment, termination, and correction are different tools

Prior approval does not itself authorize a change or exit. Section 18-209(b) allows amendment or termination only under a provision contained in the agreement or plan. The statute supplies no separate default abandonment vote.

A filed certificate is different: § 18-211 permits correction or nullification when it inaccurately records the action or was defectively or erroneously executed. The result generally relates back, except for a person substantially and adversely affected by that treatment.

The 180-day clock comes from the general filing rule

The merger provision requires any delayed date or time to be certain. Current § 18-206(b) supplies the outer limit: no later than a time on the 180th day after filing. Otherwise the transaction takes effect when the certificate is filed.

Continuity does not mean every external permission survives

Section 18-209(g) vests the constituents' rights, powers, property, debts due, and causes of action in the survivor, while preserving realty title, creditor rights, and liens and attaching all debts, liabilities, and duties. It also says the merger requires no winding up and is not a dissolution.

The filing itself cancels a nonsurviving Delaware LLC's formation certificate and implements stated formation-certificate amendments. Those statutory effects do not promise that a contract, license, permit, or registration will continue.

Appraisal exists only if the deal documents create it

Under § 18-210, the rule begins with the opposite of an automatic dissent right: no appraisal rights unless the LLC agreement, merger or consolidation agreement, or plan provides them. The Court of Chancery has jurisdiction over a right that one of those documents creates.

What trips people up

The default vote has a grandfather. Unless its agreement says otherwise, an LLC whose original formation certificate was filed and effective on or before July 31, 2015 remains governed by the second sentence of § 18-209(b) as it read on that date. The company must identify which text governs before applying the current sentence.

The 90% route is not a shortcut between two LLCs. Under § 18-209(i), a domestic LLC must own at least 90% of every otherwise-voting stock class of one or more corporations, at least one corporation must be Delaware-organized, and the plan uses a Certificate of Ownership and Merger.

Common questions

Must the ordinary agreement list statutory terms?

Section 18-209 does not enumerate minimum terms for the ordinary agreement. The public certificate does have nine specified statements, and the actual transaction documents and every constituent's law may demand more.

May the LLC agreement require a different vote?

Yes. More than 50% of current profit interests is the statutory default, not a floor. The LLC agreement may replace it and may even deny the company power to merge or consolidate. 6 Del. C. § 18-209(b), (h).

Does a member automatically receive appraisal rights?

No. Section 18-210 makes appraisal opt-in through the LLC agreement, merger or consolidation agreement, or plan.

May the certificate use a closing-condition effective time?

The certificate must state a date or time certain. A delayed time may be no later than the 180th day after filing. 6 Del. C. §§ 18-209(c)(6), 18-206(b).
