LLC Merger Approval and Filing Requirements in South Dakota
At a glance
| Governing law, route name, and transaction scope | South Dakota LLC Act, SDCL ch. 47-34A, art. IX, §§ 47-34A-901 to -905 and -914 to -915; calls the transaction merger. Conversion and domestication occupy separate Article IX routes and are excluded (§§ 47-34A-906 to -913) |
|---|---|
| Eligible domestic, foreign, and other-form constituents and survivors | LLC may merge with ≥1 “organization”: domestic/foreign LLC, corporation, general/limited partnership and LLP forms, business trust, or any other domestic/foreign profit/nonprofit person with a governing statute. Each other organization's law must authorize/not prohibit, and it must comply with that law (§§ 47-34A-901(9), -902(a)) |
| Plan of merger contents, consideration, and survivor governing documents | Plan must be in a record and state constituent names/forms; survivor name/ form and whether created; terms; conversion of interests into money, survivor interests, or other consideration; and proposed new-survivor organizational documents or amendments to a preexisting survivor's record-form documents (§ 47-34A-902(b)) |
| Member approval threshold, operating-agreement control, and other constituents' approvals | All members of each constituent LLC consent by statutory default; operating agreement governs where it otherwise provides, within mandatory limits. Each other constituent signs and approves under its governing statute (§§ 47-34A-103(a), -903(a), -904(a)) |
| Meeting notice, written consent, waiver, and new-personal-liability consent | No fixed merger meeting-notice, waiver, quorum, or writing rule; required member action may occur without meeting, and signed proxy is allowed. Member acquiring personal liability must consent unless operating agreement allows fewer-than-all merger approval and that member consented to that provision; general amendment consent is insufficient (§§ 47-34A-404.1(d)- (e), -914) |
| Merger filing contents, signers, companion filings, and filing offices | Every constituent signs Articles of Merger; each constituent LLC delivers them to Secretary of State. Include constituent/survivor names/forms/laws, new-survivor status, effective date, new public organic record or existing- record amendments, each approval, unregistered foreign survivor's service office, and other-law additions. LLC signer is manager, member, organizer, or fiduciary as applicable; state name/capacity (§§ 47-34A-205, -904) |
| Effective time, delayed date, plan amendment, abandonment, and correction | LLC survivor: later of filing compliance and stated time; general filing rule caps delay at day 90 and pulls an overlong date back to day 90. Other- form survivor follows its governing law. Before articles delivery, plan or same consent may amend/abandon unless plan prohibits. Correction relates back except against adverse reliance (§§ 47-34A-206(d), -207, -903(b), -904(d)) |
| Survivor existence, property, debts, proceedings, records, and registrations | Survivor continues/is created; nonsurvivors cease; property vests; debts/ liabilities continue; proceedings continue; lawful rights/powers/purposes vest; plan terms and new/amended public organic records take effect; and a disappearing LLC need not dissolve. Statute states no separate foreign- registration cancellation (§ 47-34A-905(a)) |
| Appraisal or dissent, creditor protection, and foreign-survivor service | No express appraisal, dissent, fair-value, or payment right in Article IX. Debts/obligations/liabilities continue in survivor; no separate lien clause. Foreign survivor consents to South Dakota jurisdiction for covered debts; if unregistered, appoints Secretary of State for service, with office addresses in Articles (§§ 47-34A-904(b)(7), -905) |
| Short-form and other statutory routes and special-entity boundaries | No parent-subsidiary or ownership-threshold shortcut in Article IX. Its proceedings do not preclude merger under other law. Broad “organization” definition reaches profit/nonprofit and other forms with governing statutes, but each form's own law and all special/regulatory restrictions still control (§§ 47-34A-901(9), -915; art. IX index) |
Requirements one by one
Eligibility follows the other organization's own law
South Dakota's “organization” definition includes domestic or foreign, profit or nonprofit entities and names LLCs, corporations, business trusts, and both general- and limited-partnership forms. Current § 47-34A-902(a) then requires the other organization's statute to authorize the merger, the enacting jurisdiction not to prohibit it, and the organization to follow that statute.
The plan must tell the complete before-and-after story
Section 47-34A-902(b) requires a plan in a record. Beyond names and forms, it must say whether the survivor is created, state terms and interest-conversion mechanics, and carry the new survivor's proposed record-form organizational documents or the preexisting survivor's amendments.
All-member consent is a default with a personal-liability backstop
Current § 47-34A-903(a) requires every member of a constituent LLC to consent, subject to the operating agreement's control and § 47-34A-914. Required action may occur without a meeting, and a member may use a signed proxy. The statute states no fixed merger notice, waiver, quorum, or consent-form rule. SDCL § 47-34A-404.1(d)-(e).
If a member would acquire personal liability, that member must consent. The only exception requires both an operating-agreement provision allowing fewer- than-all merger approval and that member's consent to that provision; consent to a generic fewer-than-all amendment clause does not count.
Every constituent signs the public record
Under § 47-34A-904, every constituent signs Articles of Merger and each constituent LLC delivers them to the Secretary of State. The articles identify constituents and survivor, give the effective date and approvals, carry a new public organizational record or amendments, and supply an unregistered foreign survivor's service office.
For the LLC, § 47-34A-205 selects a manager in a manager-managed company, a member in a member-managed company, an organizer before formation, or a court- appointed fiduciary. The signature states the person's name and capacity.
The plan can change or end only before delivery
After approval but before Articles of Merger are delivered, the plan may supply the amendment or abandonment method. Unless the plan prohibits it, the same consent required for approval may act. Current § 47-34A-903(b).
An LLC survivor takes effect upon the later of filing compliance and the time stated in the articles. The general filing rule pulls any date after day 90 back to day 90. Articles of correction generally relate back but do not do so against a person who relied on the uncorrected record and is adversely affected. SDCL §§ 47-34A-206(d), -207(c), -904(d).
Continuity covers property, debts, and proceedings
Current § 47-34A-905 continues or creates the survivor, ends the separate existence of nonsurvivors, vests their property, continues debts and liabilities, carries pending proceedings and lawful powers, and makes the plan and public organic-record changes effective. A disappearing LLC need not be dissolved under the winding-up provisions.
For a foreign survivor, South Dakota jurisdiction remains available for a covered constituent debt. If that survivor is not authorized in South Dakota, the Secretary of State becomes its service agent.
What trips people up
Unanimity and separate liability consent answer different questions. Even if an operating agreement lowers the ordinary approval threshold, a member who would acquire personal liability still receives § 47-34A-914's protection unless that member consented to the precise fewer-than-all merger provision.
Article IX has no appraisal, dissent, fair-value, payment, parent-subsidiary, or ownership-threshold section. Its last section says other-law merger routes are not precluded, but it does not make a particular alternative available on the facts. SDCL § 47-34A-915.
Common questions
Can a South Dakota LLC merge with a nonprofit entity?
Potentially. The definition includes nonprofit organizations with a governing statute, but that other statute must authorize the merger and the organization must comply with it. SDCL §§ 47-34A-901(9), -902(a).
Must the members hold a meeting?
No. Section 47-34A-404.1(d) allows action requiring member consent without a meeting, and subsection (e) permits a signed proxy.
Is a delayed date longer than 90 days rejected?
The statute supplies a different result: if the stated delayed date is later than day 90 after filing, the record becomes effective on day 90. SDCL § 47-34A-206(d).
Does the Act give members appraisal rights?
No express appraisal procedure appears in Article IX. The plan and operating agreement should still be reviewed for contractual rights and another constituent's governing law may supply its own rights.
