Two people start a business together as equals. They split everything down the middle, fifty-fifty, because it feels fair and because they trust each other. The company grows, and for a while the equal partnership works exactly as intended. Then a real decision arrives, something that matters, and for the first time the two owners want opposite things. One wants to reinvest; the other wants to take money out. One wants to hire; the other wants to sell. Neither will move. And because they own the company in equal shares, neither one can outvote the other.

That is deadlock, and it is one of the most frequent and most painful problems a business attorney sees. The 50/50 split that felt like the fairest possible arrangement at formation turns out to be the one structure with no built-in way to break a tie. The business does not fail because the idea was bad or the market turned. It fails because the two people who own it can no longer make a decision, and the law they never read does not hand either of them a tie-breaker.

This guide explains what actually happens when a 50/50 LLC deadlocks in Maryland and Pennsylvania. It covers why an equal split produces a stalemate, what the operating agreement controls, whether one owner can force a buyout of the other, how judicial dissolution works in each state and how the two states differ, the other realistic exits, and the deadlock-breaking provisions that keep the whole problem from ever arising. If your dispute is broader than a pure voting tie, our overview of a business partner dispute in Maryland maps the wider landscape of co-owner conflict, and our guide on how to remove a business partner or LLC member focuses on the narrower question of getting someone out.

Deadlock is a specific legal concept, not merely a synonym for a dispute. A deadlock exists when the owners cannot produce the vote that the statute or the operating agreement requires in order to act, so the company is unable to make decisions. It is the difference between two owners who disagree but can still resolve the matter by a vote, and two owners whose votes cancel each other out so completely that nothing can be decided at all.

Deadlock takes a few recognizable forms:

• Voting deadlock. The classic case. Two members hold equal voting power, they want opposite outcomes, and no decision that requires their consent can be reached.
• Management deadlock. In a manager-managed company with two equal managers, or a board split evenly, the managers cannot agree and the members cannot break the tie.
• Operational paralysis. The stalemate spreads beyond a single vote into the day-to-day running of the business, so bills, contracts, hires, and strategy all stall because neither owner will cede ground.

The reason deadlock matters legally is that both Maryland and Pennsylvania give courts a specific tool to address it, judicial dissolution, and both states use a demanding standard tied to whether it is still practicable to carry on the business. Ordinary friction does not meet that standard. A genuine, persistent inability to make the decisions the business needs can. Understanding where your situation falls on that spectrum is the first step in deciding what to do about it.

The reason a 50/50 LLC is so prone to deadlock is not bad luck. It is arithmetic built into the default voting rules of both states. Those rules assume that someone will be able to assemble a majority. In an equal two-owner company, no one ever can.

Maryland: a majority of the profits interests

Under Md. Code, Corps. and Ass’ns Section 4A-403(b), unless the operating agreement provides otherwise, members vote in proportion to their respective interests in profits, and decisions concerning the affairs of the LLC require the consent of members holding at least a majority of those profits interests. Maryland allocates profits interests, by default, in proportion to the value of each member’s capital contributions under Section 4A-503. In a genuine 50/50 company, each owner holds exactly half of the profits interests. Half is not a majority. So neither owner can ever assemble the majority that Section 4A-403(b) requires, and no ordinary-course decision can be forced through. Other actions may require unanimous consent under specific provisions of Title 4A or under the operating agreement. In addition, if the operating agreement does not specify how it may be amended, Section 4A-402(c) requires all members to agree to an amendment, which ordinarily prevents two deadlocked owners from adding a tie-breaker after the dispute begins.

Pennsylvania: a majority of the members

Pennsylvania reaches the same dead end by a different route. Under 15 Pa.C.S. Section 8847(b), in a member-managed LLC each member has equal rights in management, a difference arising in the ordinary course of the company’s activities may be decided by a majority of the members, and an act outside the ordinary course, along with any amendment to the certificate of organization or the operating agreement, may be undertaken only with the affirmative vote or consent of all members. Notice the counting method. Pennsylvania’s default is per capita, one member one vote, rather than by profits interest. With only two members, a majority of the members means both of them. So in a two-owner Pennsylvania LLC, even an ordinary-course decision effectively requires unanimity, and a single no from either owner blocks the company from acting.

Before turning to what a court can do, understand what your own documents may already do. An LLC is fundamentally a contract among its members, and the operating agreement is that contract. Both the Maryland and Pennsylvania statutes defer to it on nearly every question that matters to a deadlock. The recurring statutory phrase is that the default rules apply only where the operating agreement is silent or does not provide otherwise. A well-drafted agreement can supply a clean, predictable way out of a tie. A silent or generic one leaves the owners with the blunt statutory defaults and, usually, with a lawyer.

When a deadlock arises, the first task is a careful reading of the operating agreement for the provisions that will decide the outcome:

• A tie-breaking or deadlock-resolution mechanism, such as a buy-sell trigger, a neutral tie-breaking member, or a provisional manager.
• A buy-sell or buyout provision, including the triggering events, who buys, and how the price is set.
• A valuation method, whether a fixed value updated periodically, a formula, or an independent appraisal.
• Any mandatory mediation or arbitration requirement before a member can go to court.
• Custom voting thresholds that change the default majority or unanimity rules.
• Any modification of the default fiduciary duties among members or managers, within the limits each state allows.

This is the question most deadlocked owners actually want answered, so it is worth being precise. There are two ways a buyout can be forced, and they behave very differently.

By contract

If the operating agreement contains a buy-sell or deadlock provision, one owner can often trigger a buyout by following the contract. A shotgun clause, for example, lets one owner name a price and forces the other to buy or sell at that price. A put or call right tied to a defined deadlock event can compel a purchase or a sale on preset terms. When this machinery exists, the buyout is a contractual right, and the discipline is in honoring the exact procedure. This is the cleanest way to force a separation, and it is available only because someone had the foresight to draft it.

By court order

When there is no contractual buyout, the picture changes and the two states diverge. Neither Maryland nor Pennsylvania hands a deadlocked owner a simple statutory right to demand that the other buy them out. What the statutes provide is a right to petition for judicial dissolution when the applicable statutory ground exists. The risk that a viable business may otherwise be wound up can create settlement leverage and may lead the parties to negotiate a buyout. That practical leverage should not be confused with a general statutory or equitable right to compel a buyout. The mechanics of what each state’s statute does provide differ:

• Maryland has no express buyout-in-lieu-of-dissolution provision for LLCs. A court may enforce the operating agreement by injunction or other fair and appropriate relief under Section 4A-402(d), and the practical gravity of a dissolution case frequently produces a negotiated buyout, but the statute does not command one merely because the members are deadlocked.
• Pennsylvania goes further. Under Section 8871(b), in a proceeding brought on the oppression ground, the court may order a remedy other than dissolution. The statute does not enumerate the available alternative remedies or guarantee a buyout, although a party may ask the court to consider appropriately tailored relief based on the facts and the court’s authority under that provision. That express alternative applies only when the petition rests on oppressive conduct by those in control, not on a pure, blameless deadlock.

When there is no contractual exit and no negotiated deal is possible, a Maryland member can ask a court to dissolve the LLC. Under Md. Code, Corps. and Ass’ns Section 4A-903, on application by or for a member, the circuit court of the county in which the LLC’s principal office is located may decree dissolution whenever it is not reasonably practicable to carry on the business in conformity with the articles of organization or the operating agreement. This is Maryland’s principal statutory remedy for a deadlocked owner.

The standard is exacting. It is not enough that the owners are unhappy or that they argue. A court examines the LLC’s governing documents, its stated and actual business purpose, the members’ voting and management structure, the nature and duration of the deadlock, and whether the company can still operate in conformity with those documents. A true, persistent voting deadlock in a 50/50 company that cannot make the decisions the business needs is the paradigm case the statute was written for. Ordinary dissatisfaction is not.

Two features of Maryland law are worth emphasizing. First, judicial dissolution places the LLC into dissolution and winding up; it does not automatically transfer the business to one owner and allow that owner to continue operating it outside the winding-up process. During winding up, the company generally resolves its affairs, addresses liabilities, disposes of or distributes assets, and proceeds toward termination. The other statutory causes of dissolution in Section 4A-902 include an event specified in the operating agreement, unanimous member consent, entry of a decree of judicial dissolution, and the LLC having no members for ninety consecutive days, subject to the statutory continuation procedures. If your goal is to keep the business running without your co-owner, dissolution is usually the wrong tool, and a buyout is what you actually want. Our guide on how to close a business in Maryland covers the mechanics of winding up if that is genuinely where things land.

Second, Maryland does not provide the broad statutory oppression and expulsion remedies found in states that adopted the Uniform Limited Liability Company Act. A court will address a genuine breakdown through the dissolution power in Section 4A-903 and through its power under Section 4A-402(d) to enforce the operating agreement by injunction or other fair and appropriate relief. Where one owner’s conduct, rather than a blameless disagreement, is driving the dispute, a claim for breach of the operating agreement or breach of fiduciary duty may also be available. In Plank v. Cherneski, 469 Md. 548 (2020), the Supreme Court of Maryland confirmed that managing members owe common-law fiduciary duties to the LLC and to the other members based on principles of agency, though whether a duty exists and what it requires depends on the person’s role, the operating agreement, and the facts. For the framework of a Maryland contract claim, see our guide to breach of contract in Maryland and Pennsylvania.

Pennsylvania overhauled its LLC law with Act 170 of 2016, which replaced the Commonwealth’s prior statutes with new chapters modeled on the uniform acts. The current law took effect for entities formed on or after February 21, 2017, and for every existing entity on April 1, 2017, regardless of when it was formed. If your Pennsylvania LLC predates 2017 and its agreement has not been reviewed since, it was drafted against a statute that no longer governs. The dissolution rules now live in 15 Pa.C.S. Section 8871, not the repealed provisions of the former Chapter 89.

Section 8871(a)(4) is broader than Maryland’s single ground. On application by a member, a court may enter an order dissolving the company on the grounds that:

• the conduct of all or substantially all the company’s activities and affairs is unlawful;
• it is not reasonably practicable to carry on the company’s activities and affairs in conformity with the certificate of organization and the operating agreement; or
• the managers or those members in control of the company have acted, are acting, or will act in a manner that is illegal or fraudulent, or have acted or are acting in a manner that is oppressive and was, is, or will be directly harmful to the applicant.

The middle ground, not reasonably practicable, is the direct analog to Maryland’s Section 4A-903 and is the natural fit for a pure voting deadlock. The added illegal, fraudulent, and oppressive-conduct grounds give a Pennsylvania member frozen out or mistreated by a controlling co-owner a route that Maryland’s LLC statute does not expressly provide.

Pennsylvania also offers something Maryland’s LLC Act does not: an express alternative to dissolution. Under Section 8871(b), in a proceeding brought on the oppression ground, the court may order a remedy other than dissolution. That provision authorizes the court to consider relief short of dissolution in an oppression proceeding. Because the statute does not specify the available alternative remedies, the precise relief must be determined from the claims, requested remedy, governing documents, and circumstances of the case. Read the provision carefully, though. The express other-remedies power is tied specifically to the oppression ground, not to the blameless not-reasonably-practicable ground. A member whose only claim is a neutral deadlock cannot point to Section 8871(b) itself for a mandated buyout.

The two states reach a deadlocked 50/50 LLC through similar principles but different statutes, and the differences matter to strategy. The table below summarizes the default rules for a member-managed LLC. In every row, a written operating agreement can change the default, except where the row notes that a rule is non-waivable.

The headline takeaways: Pennsylvania recognizes oppression as a distinct dissolution ground for LLCs and expressly authorizes a lesser remedy on that ground, while Maryland channels a genuine breakdown through the single not-reasonably-practicable standard plus its general equitable and fiduciary tools. In both states, the prospect of winding up a viable business may give the parties a strong economic incentive to negotiate a buyout or another settlement. The governing statutes, however, do not create an automatic buyout remedy for a neutral deadlock, and the relief legally available depends on the operating agreement, the asserted statutory ground, and the facts of the case.

Litigation is expensive, slow, and public, and its outcome is never guaranteed. For most deadlocked owners, the better path runs through one of the following, with a dissolution petition held in reserve as leverage rather than filed first.

A negotiated buyout

The cleanest resolution is almost always one owner buying the other’s interest, on agreed terms, in exchange for a full mutual release. A negotiated buyout avoids the cost and uncertainty of court, keeps the dispute private, and lets the parties tailor the price, payment structure, and timing to their real interests. A sound buyout addresses the price and the valuation method, the payment structure and any security for deferred payments, a full release of claims, the redemption or assignment of the interest, the treatment of any personal guaranties the departing owner signed, and the tax consequences for both the company and the departing owner. Because a buyout of a co-owner is closely related to buying that person’s stake in the business, our guide on how to buy a business in Maryland is a useful companion.

Mediation or arbitration

A neutral third party can break a logjam that the owners cannot break themselves. Mediation is non-binding and aims to broker a deal; arbitration produces a binding decision. Many well-drafted operating agreements require one or both before a member may go to court. Even where the agreement is silent, the parties can agree to mediate, and doing so is frequently faster and cheaper than litigation.

One owner sells, or both do

Sometimes the right answer is a sale. One owner may sell to the other, the owners may sell the whole company to a third party and split the proceeds, or, if the relationship allows it, they may divide the business. Where a departing owner will be bound by a restrictive covenant, review our discussion of whether non-compete agreements are enforceable in Maryland before relying on one, and our guide on how to sell a business in Maryland covers the mechanics of a full exit.

Although the LLC is the most common form for a two-owner business, the same 50/50 problem arises in closely held corporations, where different statutes apply. If your entity is actually a corporation, the analysis shifts.

Maryland corporations

Under Md. Code, Corps. and Ass’ns Section 3-413, stockholders entitled to cast at least twenty-five percent of the votes in the election of directors may petition a court to dissolve the corporation when the directors are so divided that required board action cannot be obtained, or when the stockholders are so divided that directors cannot be elected. A stockholder may also petition on the ground that those in control have acted in a manner that is illegal, oppressive, or fraudulent. As with LLCs, Maryland courts prefer remedies short of dissolving a functioning corporation. In Bontempo v. Lare, 444 Md. 344 (2015), the Court of Appeals addressed oppression in a closely held corporation and confirmed that courts may use equitable remedies short of corporate dissolution.

Pennsylvania corporations

Pennsylvania’s corporate deadlock framework is more developed. Under 15 Pa.C.S. Section 1981, a shareholder or director may seek involuntary winding up and dissolution when the acts of those in control are illegal, oppressive, or fraudulent and dissolution is beneficial to the shareholders, when corporate assets are being misapplied or wasted, or when the directors are deadlocked, the shareholders cannot break the deadlock, and irreparable injury is being suffered or threatened. Separately, under 15 Pa.C.S. Section 1767, a court may appoint a custodian on deadlock to continue the business rather than liquidate it, an intermediate remedy that keeps the company running. Notably, a court will not impose a custodian or similar relief if the shareholders have already provided for a provisional director or another means of resolving a deadlock, which is one more reason to build these mechanisms into the governing documents.

Because many small businesses that call themselves partnerships or corporations are legally something else, the first step is always confirming the real entity type in the state records before deciding which rules apply. For a two-owner general partnership, the exit rules live in the partnership agreement and each state’s partnership statute, a subject our guide on business partnership agreements in Maryland and Pennsylvania addresses in detail.

Nearly every deadlock this firm sees traces back to the same root cause: a 50/50 ownership split with no tie-breaker in the operating agreement, or no operating agreement at all. The fix is inexpensive and reliable when it is done at formation, and close to impossible once the owners have stopped agreeing. If you are forming or restructuring a two-owner company, these are the mechanisms worth considering.

• Buy-sell trigger. A provision that lets one owner, on a defined deadlock event, buy out the other, or requires a departing owner to sell, on a preset valuation and payment schedule.
• Shotgun clause. Also called a buy-sell or Texas shootout. One owner names a per-unit price; the other must either sell at that price or buy the offering owner out at the same price. Variations use sealed bids or an appraisal. It forces a clean break and discourages lowball offers, though it can favor the owner with deeper pockets.
• Neutral tie-breaker. A designated third person, an odd-numbered board, or a provisional manager empowered to break a deadlock on defined categories of decisions.
• Mandatory mediation or arbitration. A requirement that the owners mediate, and then arbitrate if mediation fails, before anyone files suit, which keeps most disputes out of court entirely.
• Custom voting thresholds. Tailored supermajority or unanimity rules for specific decisions, so the default all-or-nothing rules do not apply to routine matters.
• Defined valuation method. A fixed value updated periodically, a formula, or an independent appraisal agreed in advance, which removes the single most contested issue in any buyout.
• Put and call rights. Options that let one owner compel a purchase, or compel a sale, on preset terms tied to specified trigger events.

• Owning it 50/50 with no tie-breaker. The equal split with no deadlock mechanism is the single most common cause of the problem. The fix is easy at formation and nearly impossible afterward.
• Operating with no written agreement at all. Silence hands you the statutory defaults, which are designed to preserve a stalemate, not to break one. In Maryland and Pennsylvania alike, the defaults offer no tie-breaker.
• Assuming one owner can simply vote the other out. Neither state gives a general power to expel a co-owner, and in a 50/50 company no one has the votes anyway.
• Expecting a court to hand you a buyout on demand. Dissolution is the statutory remedy for deadlock, not a compelled buyout. In Maryland there is no LLC buyout statute for a neutral deadlock, and in Pennsylvania the express other-remedies power attaches only to the oppression ground.
• Trying to fix governance after the fight starts. Amending the operating agreement usually requires the unanimity or majority the deadlock has already destroyed, so the moment to add a tie-breaker is before the dispute, not during it.
• Resorting to self-help. Lockouts, frozen accounts, and unilateral control grabs invite injunctions and fiduciary-duty claims and usually worsen your position.
• Treating dissolution as a way to take the business. Dissolution ordinarily begins the winding-up process; it does not itself transfer the company or its operating business to one owner. If the goal is for one owner to continue the business, a negotiated or contractually authorized buyout, redemption, asset transaction, or other properly structured separation is ordinarily the more direct tool.
• Waiting too long. Evidence, leverage, and legal deadlines all erode with time. Maryland’s general three-year limitations period under Section 5-101 can bar a claim that once looked strong.

Most of these mistakes are far cheaper to avoid than to fix, and the cheapest fix of all is a well-drafted operating agreement with a clear deadlock, buyout, and valuation mechanism built in before a dispute ever arises.

A deadlock is a governance stalemate in which the owners cannot produce the vote the law or the operating agreement requires to act, so the company cannot make decisions. It is most common in a two-member LLC owned in equal shares, because neither owner can outvote the other. In a Maryland LLC, ordinary-course decisions require the consent of members holding at least a majority of the interests in profits under Md. Code, Corps. and Ass’ns Section 4A-403(b), and two equal members each hold exactly half, so neither reaches a majority. In a Pennsylvania member-managed LLC, an ordinary-course difference is decided by a majority of the members under 15 Pa.C.S. Section 8847(b), and with only two members a majority requires both of them, so a single no blocks action. Either way, the result is the same: nothing that needs a vote can get through, and the business freezes.

Not by a simple vote. Maryland provides no general statutory power for one member to expel another, and in a 50/50 LLC neither member has the votes to remove the other in any event. Under Section 4A-606(2), a member is removed only in accordance with the operating agreement, so forced removal exists only if the agreement created that power. What one deadlocked owner can realistically pursue is a negotiated buyout, a claim for breach of the operating agreement or breach of fiduciary duty where the facts support it, or a petition for judicial dissolution under Section 4A-903. A dissolution petition often becomes leverage toward a buyout rather than an actual wind-up, but Maryland’s LLC statute does not itself force a buyout merely because the members are deadlocked.

Maryland’s LLC Act does not contain an express buyout-in-lieu-of-dissolution remedy for a deadlocked LLC. A buyout may become the practical result of negotiation or settlement, particularly when both owners wish to preserve the business’s going-concern value. Maryland’s LLC Act, however, does not establish a general preference for a buyout or give a court express authority to compel one merely because the members are deadlocked. Section 4A-402(d) authorizes relief to enforce the operating agreement, while Section 4A-903 authorizes dissolution when its statutory standard is met. Pennsylvania’s Section 8871(b) expressly permits a remedy other than dissolution in a proceeding brought on the oppression ground, but that provision does not enumerate or guarantee specific alternative remedies.

Under Md. Code, Corps. and Ass’ns Section 4A-903, on application by or for a member, the circuit court of the county where the LLC’s principal office is located may decree dissolution whenever it is not reasonably practicable to carry on the business in conformity with the articles of organization or the operating agreement. That standard requires more than ordinary friction or disappointment. A court examines the governing documents, the company’s stated and actual purpose, the voting and management structure, the nature and duration of the deadlock, and whether the company can still operate in conformity with those documents. Because a forced wind-up often destroys going-concern value, dissolution is treated as a last resort.

Pennsylvania’s current LLC statute, enacted by Act 170 of 2016 and in effect for all existing LLCs since April 1, 2017, is broader in two ways. First, 15 Pa.C.S. Section 8871(a)(4) lets a court dissolve on three families of grounds: the company’s activities are unlawful, it is not reasonably practicable to carry on in conformity with the certificate of organization and operating agreement, or those in control have acted illegally, fraudulently, or oppressively in a way directly harmful to the applicant. Maryland’s Section 4A-903 has only the single not-reasonably-practicable ground for LLCs. Second, Section 8871(b) expressly authorizes a remedy other than dissolution, but only in a proceeding brought on the oppression ground. Pennsylvania also makes the Section 8871(a)(4) dissolution grounds non-waivable under Section 8815(c)(15), so an operating agreement cannot contract them away.

The statutory defaults govern, and they are built for a stalemate, not for breaking one. In Maryland, unless the operating agreement provides otherwise, ordinary decisions require the consent of members holding at least a majority of the interests in profits. If the operating agreement does not specify how it may be amended, all members must agree to an amendment under Section 4A-402(c). A deadlocked 50/50 LLC therefore ordinarily cannot amend a silent operating agreement to add a tie-breaker without both members’ consent. In Pennsylvania, ordinary decisions need a majority of the members, which with two owners means both, while acts outside the ordinary course and any amendment to the operating agreement require all members under Section 8847(b). The only realistic paths become negotiation, litigation, or a dissolution petition.

A shotgun clause, sometimes called a buy-sell or Texas shootout provision, is a contractual tie-breaker. In one common form, either owner may name a per-unit price; the other owner must then either sell at that price or buy the offering owner out at the same price. Variations use sealed bids or an appraisal-based valuation. The appeal is that it forces a clean separation and discourages lowball offers, because the person naming the price can end up on either side of the deal. These clauses are powerful but not right for everyone, since they can favor the owner with more cash or better financing. Related tools include mandatory mediation or arbitration, a neutral tie-breaking member or provisional manager, and put or call rights tied to defined trigger events. The essential point is that these mechanisms have to be in the operating agreement before the dispute, because a deadlocked company usually cannot agree to add them afterward.

It varies widely. When the operating agreement contains a working buy-sell or deadlock mechanism, a separation can often be completed in a matter of weeks through the contractual process. When there is no such mechanism and one owner has to petition for judicial dissolution or bring breach and fiduciary claims, the matter can take many months and sometimes longer, and it is far more expensive. The largest single variable is whether the governing documents already provide a tie-breaker, because that determines whether the exit is a contractual procedure or a lawsuit. Delay also carries its own cost, since evidence and leverage erode and Maryland’s general three-year limitations period under Section 5-101 can bar claims that once looked strong.
