LLC Operating Agreement Requirements in Maryland
At a glance
| Governing law and document name | Md. Code, Corporations and Associations Title 4A (Limited Liability Companies); 'operating agreement' (§§ 4A-101(q), 4A-402) |
|---|---|
| Required or optional | Optional; members 'may enter into' an agreement, and Title 4A supplies defaults unless otherwise agreed (§§ 4A-402, 4A-403, 4A-503) |
| Permitted form and signatures | Need not be written unless articles require; initial agreement needs all members' agreement, not necessarily signatures. Statutory unanimous consents are written (§§ 4A-402(b), 4A-404) |
| Adoption timing and effect | No express adoption deadline or preformation-effect rule; LLC forms on articles acceptance, and initial agreement requires all then-members (§§ 4A-202(b), 4A-402(b), 4A-601(a)) |
| Single member and assent | One-member agreement enforceable; LLC need not execute but is bound. Every present/later member and assignee is bound without execution (§ 4A-402(d)) |
| Management and authority defaults | Members manage and are ordinary-course agents unless otherwise agreed; agreement may grant exclusive management to nonmembers. Filed articles can limit member authority with presumed notice (§§ 4A-401–402) |
| Voting, economic, and transfer defaults | Votes track profit interests; ordinary matters need a majority. Profits/losses track capital contribution value and distributions track profits; later admission unanimous; assignment conveys economics only (§§ 4A-403, 4A-503, 4A-601, 4A-603–604) |
| Nonwaivable rules and duties | No numbered nonwaivable or fiduciary-duty list. Agreement is subject to articles and law; indemnity cannot cover willful misconduct/recklessness, and liability shield, reasonable inspection, enforcement, and dissolution remain statutory (§§ 4A-203(14), 4A-301, 4A-402(d), 4A-406, 4A-903) |
| Amendment, filing, and records | Agreement method controls; otherwise unanimous. Amendment may be oral unless nonunanimous or an unadmitted assignee exists. Agreement is private; written amendments go to nonconsenters and copies are inspectable (§§ 4A-402(c), 4A-406) |
Requirements one by one
The agreement is optional and generally may be oral
Section 4A-402 says members “may enter into” an operating agreement and that it need not be in writing unless the articles specifically require a writing. The initial agreement must be agreed to by every person who is then a member, but Title 4A imposes no general witness, acknowledgment, notary, or handwritten-signature condition for the agreement itself.
Maryland does not state a separate adoption deadline or expressly give a preformation agreement effect. The LLC forms when the Department accepts the articles, or at a later time stated in them (§ 4A-202). Initial membership begins at formation or a later agreement-specified time under § 4A-601.
Sole members, the LLC, later members, and assignees can be bound without signing
Section 4A-402(d) expressly validates a one-member operating agreement. The LLC need not execute the agreement but is bound by it. A duly adopted or amended agreement also binds every person who is or becomes a member or assignee, whether or not that person executed it.
That deemed binding effect is broader than the later-admission rule. Under § 4A-601, a person who acquires an interest directly from the LLC becomes a member by satisfying the agreement or, if it is silent, with unanimous member consent.
Member management and agency are the silent defaults
Section 4A-402 permits an agreement to grant exclusive management authority to nonmembers. Without such a term, § 4A-401 treats each member as an ordinary-course agent. An act outside the usual course does not bind the LLC unless the LLC authorizes it.
A private authority restriction does not create the same outsider-facing presumption as the articles. If the articles state that members' authority solely from membership is limited, persons dealing with a member are presumed to know that limitation under § 4A-401(a)(3).
Profit interests drive votes; contribution values drive allocations
Section 4A-403 weights member votes by profit interests and requires at least a majority of those interests for ordinary decisions. Disposition of substantially all business or property, merger, and conversion default to two-thirds. Bankruptcy, changing allocations or distributions, and acts making ordinary business impossible default to unanimous written consent, although § 4A-404 permits the agreement to alter those consent requirements.
The economic chain begins in § 4A-503: profits and losses default in proportion to capital contribution values, and distributions default in proportion to profit shares. These formulas are related but should not be replaced in a summary by a generic “ownership percentage.”
Assignment initially transfers only the economic interest
Section 4A-603 defaults assignment to an economic interest only. The assignee does not become a member or receive voting, management, agency, or other noneconomic rights. An assignee becomes a member through the agreement or unanimous member consent under § 4A-604.
Maryland adds a consequence worth drafting around: unless otherwise agreed, assignment of all of a member's economic interest ends that person's membership and forfeits the noneconomic interest, even though the assignee does not automatically become a member.
Title 4A has targeted statutory floors rather than a modern duty list
Title 4A does not state a numbered list of nonwaivable operating-agreement terms or a statutory formula for fiduciary-duty modification. Section 4A-402 allows the agreement to regulate any aspect of LLC affairs, business, or member relations, but only if consistent with the articles and other law.
The Act separately bars indemnification for willful misconduct or recklessness (§ 4A-203), protects members from entity obligations solely because of membership (§ 4A-301), permits member inspection subject to reasonable standards (§ 4A-406), and preserves judicial enforcement and dissolution routes in §§ 4A-402 and 4A-903.
Amendment form depends on who approved and who holds assigned economics
The agreement's amendment method controls. If it provides none, every member must agree. An amendment generally need not be written, but § 4A-402(c) requires a writing signed by an authorized person when the amendment lacks unanimous member consent or an economic interest has been assigned to an unadmitted assignee.
A written amendment must be delivered to each nonconsenting member and unadmitted assignee. The operating agreement itself is not the public formation filing; § 4A-406 instead gives members inspection rights over the agreement and all amendments.
What trips people up
- “Need not be in writing” does not eliminate every writing rule. Statutorily required unanimous consents are written, and two amendment situations require a signed writing.
- A private member-authority limit and a filed articles statement have different effects on outsiders.
- Assigning all economic rights can end the assignor's membership without admitting the assignee.
Common questions
Must every member sign the initial agreement?
Not necessarily. Every initial member must agree to it, but § 4A-402 does not impose a general signature condition unless the articles require a writing.
Can a nonmember manage the LLC?
Yes. Section 4A-402(a)(1) expressly permits the agreement to give exclusive management, control, and operation authority to persons who are not members.
Can an amendment bind someone who did not execute it?
Yes. A duly adopted amendment binds members and assignees without execution, but the approval, writing, signature, and delivery rules in § 4A-402(c) still must be followed.
