A surprising number of Maryland LLCs operate without an operating agreement. The members signed the Articles of Organization, paid the SDAT filing fee, and started doing business on the assumption that the formation document was enough. It is not. Without an operating agreement, the LLC is governed by the default rules of the Maryland Limited Liability Company Act, and most members would never agree to those rules if they understood what they actually said. A Maryland business law attorney reviewing an LLC dispute almost always finds the same root cause: the members never read the default statute, never thought about what would happen in specific scenarios, and now find themselves bound by terms they would have negotiated against if they had known.

Why the Default Rules Exist in the First Place

The Maryland LLC Act, codified in Title 4A of the Corporations and Associations Article, fills the gaps when an LLC has no operating agreement or when the operating agreement is silent on a particular issue. The default rules are intended as a backstop, not as the recommended structure for any specific business. They reflect a generic best guess about what reasonable parties might want, not what any particular group of founders actually does want.

The disconnect produces real consequences. The members assume the LLC works one way, the statute says it works another way, and the discovery happens when something has gone wrong: a partner wants out, a member dies or divorces, a business sale is pending, or a dispute makes the question of who controls the entity suddenly very important.

What the Maryland Default Rules Actually Provide

Several specific defaults deserve attention because they routinely surprise members.

Management defaults to all members. Without a written agreement designating manager-managed structure, every member has authority to act for the LLC and bind it to contracts. A two-member LLC where the parties had assumed one would handle operations and the other would be a passive investor is, by default, a member-managed LLC where either member can sign leases, hire employees, or commit the company to obligations the other never approved.

Profit and loss allocation defaults are not based on capital contributions in the way most members assume. The Maryland LLC Act provides default allocation rules that often diverge from the “we each put in $50,000 and split it 50/50” framework members had in mind. Without explicit allocation language in the operating agreement, distributions can follow rules that do not match the contribution proportions.

Voting follows specific statutory defaults. Some decisions require unanimous consent under default rules, while others require only majority vote. Members who assumed major decisions like admitting new members, amending the operating agreement, or selling substantially all assets would require their consent often discover that the default voting threshold differs from what they expected.

Transfer of membership interests is restricted by default in ways that affect estate planning and exit strategy. A member who dies or divorces under default rules typically transfers economic rights to heirs or ex-spouses but not management or voting rights, which creates a hybrid status (assignee or transferee) that the original members never anticipated.

Withdrawal and dissolution provisions under the default statute may not match what the members would have negotiated. A member who wants to exit a Maryland LLC has limited statutory rights without an operating agreement specifying buyout procedures, valuation methodology, and timing.

Deadlock resolution is essentially absent from the default statute. A 50/50 LLC where the two members cannot agree on a major decision has no statutory mechanism to break the deadlock other than judicial dissolution under specific circumstances, which is expensive, slow, and rarely produces the outcome either party wanted.

The Specific Provisions an Operating Agreement Should Cover

A properly drafted Maryland LLC operating agreement addresses the gaps the default statute leaves and replaces the defaults that do not fit the actual business.

Management structure. Member-managed or manager-managed, with specific designation of authority, signature requirements, and limitations on individual member action. The provisions should match how the business actually operates rather than restating the statutory default.

Capital contributions and additional capital calls. Specific amounts, timing, and consequences for failure to contribute, including dilution provisions or interest charges that the default rules do not provide.

Allocations and distributions. How profits and losses are allocated for tax purposes, when distributions are made, and what reserves are maintained. The provisions should align with the partnership tax framework members expect rather than the statutory defaults.

Voting and decision-making thresholds. Which decisions require unanimous consent, which require supermajority, and which require simple majority. Major decisions like admitting members, amending the operating agreement, taking on debt above a defined threshold, or selling assets should typically require higher voting thresholds than day-to-day operating decisions.

Transfer restrictions. Right of first refusal provisions, prohibited transfers, permitted estate planning transfers, and the procedures for handling a member’s death, disability, or divorce.

Buy-sell provisions. Trigger events (death, disability, retirement, termination, deadlock), valuation methodology (formula, appraisal, or fixed price periodically updated), payment terms (lump sum or installment), and any insurance funding arrangements.

Deadlock resolution. Mediation, arbitration, buy-sell triggers, or shotgun provisions that provide a path out of stalemate without resorting to litigation.

Non-compete and non-solicitation provisions for departing members. Maryland’s non-compete enforceability rules apply to LLC members in some contexts and warrant explicit drafting.

Confidentiality and trade secret protections. The default rules provide some protection but rarely enough for a business with proprietary processes, customer lists, or pricing structures.

When Updating the Operating Agreement Matters Most

Several events should trigger a review of an existing operating agreement, and the absence of an operating agreement at any of these moments is a significant problem.

Adding new members or buying out existing ones. The structure that worked for the original two founders rarely fits when a third or fourth member joins.

Significant change in capital structure. Outside investment, a loan with conversion features, or a major capital call all change the economic relationships among members.

Death, disability, or divorce of a member. The default rules produce outcomes that surprise families, and proactive provisions handle the transition cleanly.

Preparation for sale or financing. Buyers and lenders almost always require operating agreements that meet specific standards, and bringing the document up to standard takes time.

Disputes among members. The window for negotiating amendments is widest before a dispute crystallizes, narrower during early disagreement, and closed once litigation is contemplated.

Working with a Maryland business law attorney such as those at The Mundaca Law Firm, with offices in Annapolis and Washington D.C., during any of these transitions usually produces a document that prevents the problems that drive members back into legal proceedings later.

The Short Version

Maryland LLCs without operating agreements are governed by default rules that members rarely understand and rarely would have agreed to. Management authority, profit allocation, voting thresholds, transfer restrictions, and deadlock resolution all default to statutory provisions that often conflict with the founders’ actual intent. A properly drafted operating agreement, prepared with a Maryland business law attorney familiar with the state’s LLC Act and the practical issues that come up in small business operations, replaces those defaults with provisions that fit the specific business. The cost of preparing the agreement is meaningfully lower than the cost of resolving disputes that the agreement would have prevented.
