Corporate Law & Governance in Bulgaria

Bulgaria offers one of the most cost-effective corporate environments in the European Union, with a flat 10% corporate income tax rate and a straightforward company registration process. For international entrepreneurs, the country presents a genuine EU-compliant jurisdiction with access to the single market, yet the legal framework contains specific procedural and governance requirements that differ materially from Western European norms. Misunderstanding those differences is the single most common source of avoidable disputes and regulatory exposure. This article covers the principal corporate forms available in Bulgaria, the governance obligations that apply to each, the mechanisms for protecting shareholder rights, and the practical steps for resolving corporate disputes - giving decision-makers a structured roadmap before committing capital or signing constitutional documents.

The Commerce Act (Търговски закон, ТЗ) is the primary statute governing commercial entities in Bulgaria. It recognises several corporate forms, but international investors almost exclusively use two: the limited liability company (Дружество с ограничена отговорност, OOD) and the joint-stock company (Акционерно дружество, AD).

The OOD is the dominant vehicle for small and medium-sized businesses. It requires a minimum registered capital of BGN 2 (approximately EUR 1), though in practice the Commercial Register (Търговски регистър) expects a workable capital structure. Liability of each member is limited to their contribution. Management is vested in one or more managers (управители), who act as the executive organ. The OOD does not issue freely transferable shares; instead, it issues participatory interests (дялове), which are transferred by a notarised agreement and registered with the Commercial Register. This transfer restriction is a structural feature, not a contractual add-on, and it has direct implications for exit planning.

The AD is the appropriate vehicle when the business anticipates public capital markets, a broad investor base, or complex equity structures. The minimum registered capital is BGN 50,000 (approximately EUR 25,000), at least 25% of which must be paid in at incorporation. The AD issues shares that are, by default, freely transferable unless the articles of association (устав) impose restrictions. Governance is either one-tier (board of directors, съвет на директорите) or two-tier (supervisory board, надзорен съвет, and management board, управителен съвет). The two-tier structure is mandatory for credit institutions and certain regulated entities.

A third form - the limited partnership (Командитно дружество, KD) and its variant the limited partnership with shares (Командитно дружество с акции, KDA) - exists but is rarely used by foreign investors due to the unlimited liability of general partners.

Practical scenario one: a German technology company establishing a Bulgarian subsidiary for software development will almost always choose the OOD. The low capital requirement, simple management structure, and absence of mandatory audit for smaller entities make it the most efficient choice. The entire registration process, if documents are properly prepared, takes between 3 and 7 business days at the Commercial Register.

Registration of a Bulgarian company is handled exclusively through the Commercial Register, maintained by the Registry Agency (Агенция по вписванията). Since the introduction of electronic filing, applications can be submitted online using a qualified electronic signature. The state fee for registering an OOD is modest - in the low hundreds of BGN - while the AD registration fee is higher, reflecting the more complex documentation package.

The founding documents for an OOD are the memorandum of association (дружествен договор) and, where there is a sole founder, the articles of association (учредителен акт). For an AD, the founding act (учредителен акт or устав) must be notarised. The manager of an OOD must file a specimen signature (образец от подписа) certified by a notary. This is a de jure requirement that is frequently overlooked by foreign founders who assume a simple declaration suffices.

The registered address (седалище и адрес на управление) must be a real, verifiable address in Bulgaria. Using a virtual office address is legally permissible, but the Commercial Register has become increasingly attentive to addresses that appear to be purely nominal. A non-obvious risk is that an incorrect or unverifiable address can lead to failed service of official documents, which in turn creates procedural complications in litigation or regulatory proceedings.

A common mistake made by international clients is to treat the memorandum of association as a boilerplate document. In fact, the memorandum governs critical matters: the scope of the manager's authority, the voting thresholds for key decisions, the procedure for admitting new members, and the rules for distributing profits. Provisions that are not included in the memorandum cannot simply be added later by a side agreement and expected to bind third parties - they must be registered.

The beneficial ownership register (регистър на действителните собственици) is a separate obligation under the Measures Against Money Laundering Act (Закон за мерките срещу изпирането на пари, ЗМИП). Every Bulgarian legal entity must declare its ultimate beneficial owner (UBO) to the Commercial Register. Failure to comply attracts administrative fines and, in practice, can block access to banking services. Many foreign-owned structures with multi-layered holding chains underestimate the complexity of this disclosure requirement.

The shareholders agreement (споразумение между съдружниците or акционерно споразумение) is a contractual instrument that operates alongside the constitutional documents of a Bulgarian company. It is not registered with the Commercial Register and therefore does not bind third parties, but it is fully enforceable between the parties under the Obligations and Contracts Act (Закон за задълженията и договорите, ЗЗД).

The distinction between what can be achieved through the memorandum of association versus what must be placed in a shareholders agreement is a recurring source of confusion. Matters that affect the company's relationship with third parties - management authority, registered capital, transfer restrictions - must be in the registered constitutional documents to have erga omnes effect. Matters that govern the relationship between shareholders inter se - drag-along rights, tag-along rights, pre-emption procedures, deadlock resolution, non-compete obligations - are typically placed in the shareholders agreement.

Bulgarian courts have consistently upheld shareholders agreements as binding contracts, applying general contract law principles. However, a shareholders agreement cannot override mandatory provisions of the Commerce Act. For example, the Commerce Act (Article 137) sets out the matters that must be decided by the general meeting of an OOD, and a shareholders agreement cannot validly delegate those decisions to a manager or a committee.

Deadlock provisions deserve particular attention. In an OOD with two equal shareholders, a deadlock at the general meeting level can paralyse the company. The Commerce Act does not provide a statutory deadlock resolution mechanism equivalent to those found in some common law jurisdictions. Practitioners therefore recommend including a contractual mechanism - such as a Russian roulette clause or a buy-sell provision - in the shareholders agreement, combined with a clear arbitration clause specifying the seat and rules.

Practical scenario two: a joint venture between a Bulgarian and a UAE investor, each holding 50% of an OOD, encounters a deadlock over the appointment of a new manager. Without a contractual deadlock mechanism, the only legal recourse is a court application under Article 155 of the Commerce Act, which allows a court to appoint a temporary manager. This process can take several months and is disruptive to operations. A well-drafted shareholders agreement with a contractual buy-out mechanism resolves the same situation in 30 to 60 days.

Governance of an AD involves additional statutory requirements. The board of directors or management board must hold meetings with a quorum of more than half of its members, and decisions require a simple majority unless the articles specify a higher threshold. Minutes must be kept in a bound register. The supervisory board in a two-tier AD has a mandatory oversight function and cannot be reduced to a nominal role - its members have personal liability for failure to supervise.

The manager of an OOD and the members of the board of an AD owe fiduciary duties to the company under the Commerce Act. Article 145 of the Commerce Act establishes the liability of a manager for damages caused to the company through culpable conduct. The standard is one of a diligent merchant (грижата на добрия търговец), which Bulgarian courts interpret as an objective standard of reasonable commercial prudence.

Director liability in Bulgaria is personal and unlimited. A manager cannot contractually limit their liability to the company below the statutory standard. In practice, this means that a manager who approves a transaction that damages the company - even without personal enrichment - can be held personally liable for the full amount of the loss.

The derivative action (косвен иск) is the procedural mechanism by which shareholders can enforce the company's claims against a manager on behalf of the company. Under Article 145 of the Commerce Act, any shareholder or member can bring such a claim if the company's management fails to do so. The threshold for initiating a derivative action is relatively low compared to many EU jurisdictions, which makes it a practically available tool rather than a theoretical one.

A non-obvious risk for foreign directors serving on Bulgarian boards is the interaction between director liability and insolvency law. The Insolvency Act (Закон за несъстоятелността, ЗН) imposes an obligation on managers to file for insolvency within 30 days of the company becoming insolvent or over-indebted. Failure to file within this period exposes the manager to personal liability for creditor losses incurred after the deadline. Many foreign managers are unaware of this 30-day trigger, particularly when the Bulgarian entity is a subsidiary and insolvency decisions are made at group level.

Conflicts of interest are regulated under Article 142 of the Commerce Act, which requires a manager to disclose any personal interest in a transaction and to obtain approval from the general meeting before proceeding. Failure to obtain approval does not automatically void the transaction, but it exposes the manager to a damages claim and can be used as grounds for removal.

Bulgarian corporate law provides shareholders with a range of statutory rights that cannot be waived by the constitutional documents. These include the right to participate in and vote at general meetings, the right to receive dividends when declared, the right to inspect the company's books and records, and the right to receive a liquidation share upon dissolution.

The general meeting of an OOD (общо събрание) must be convened at least once per year to approve the annual financial statements and to decide on profit distribution. The Commerce Act (Article 139) sets out the minimum notice period: members must be notified at least 7 days before the meeting. A common mistake is to hold general meetings without proper notice, which renders the resolutions adopted at those meetings voidable. In practice, a shareholder who was not properly notified can challenge the resolution before the district court within 3 months of learning of it, under Article 74 of the Commerce Act.

The challenge of general meeting resolutions (иск за отмяна на решение на общото събрание) is one of the most frequently litigated corporate law matters in Bulgaria. The grounds include procedural irregularities (improper notice, lack of quorum) and substantive violations (resolutions that contradict the law or the constitutional documents). The district court (районен съд or окръжен съд, depending on the registered capital) has jurisdiction. Proceedings at first instance typically take 6 to 18 months, with appeals extending the timeline further.

Practical scenario three: a minority shareholder in a Bulgarian AD holding 15% of the share capital discovers that the majority shareholder has caused the company to enter into a series of related-party transactions at below-market prices, effectively transferring value out of the company. The minority shareholder has several available tools: a derivative action against the directors under Article 145 of the Commerce Act, a challenge to the resolutions approving the transactions under Article 74, and a request for a special audit (специална проверка) under Article 120 of the Commerce Act, which allows shareholders holding at least 10% of the capital to demand an independent examination of specific transactions.

Arbitration is an increasingly common mechanism for resolving Bulgarian corporate disputes, particularly in joint ventures with foreign investors. The International Commercial Arbitration Act (Закон за международния търговски арбитраж, ЗМТА) governs arbitration with an international element, while purely domestic disputes can be referred to the Arbitration Court at the Bulgarian Chamber of Commerce and Industry (Арбитражен съд при Българската търговско-промишлена палата). Arbitration clauses in shareholders agreements are generally enforceable, but certain corporate law matters - such as the challenge of general meeting resolutions - are considered non-arbitrable under Bulgarian law and must be resolved by the state courts.

The cost of corporate litigation in Bulgaria is relatively moderate by EU standards. Court fees are calculated as a percentage of the claim value, with caps applicable in certain categories. Lawyers' fees for corporate dispute matters typically start from the low thousands of EUR for straightforward cases, rising significantly for complex multi-party disputes or those involving cross-border elements. The practical viability of litigation must be assessed against the amount at stake: for disputes below EUR 10,000, the procedural burden often outweighs the potential recovery.

The Commerce Act dedicates a separate chapter to transformations (преобразувания), covering mergers (сливане), acquisitions (вливане), demergers (разделяне), and spin-offs (отделяне). Each transformation type has specific procedural requirements, including the preparation of a transformation plan (план за преобразуване), an independent expert valuation, and approval by the general meeting with a qualified majority - typically two-thirds of the represented capital for an OOD and three-quarters for an AD.

The transformation plan must be filed with the Commercial Register at least 30 days before the general meeting that will vote on it. This 30-day period is mandatory and cannot be shortened by agreement. Creditors of the transforming company have the right to demand security or early repayment of their claims if the transformation materially affects their position. In practice, managing creditor claims is one of the most time-consuming aspects of a Bulgarian M&A transaction structured as a statutory merger.

Share and interest transfers in the context of M&A transactions require careful attention to the constitutional documents. For an OOD, the transfer of a participatory interest to a third party (i.e., a non-member) requires the consent of the general meeting by a simple majority, unless the memorandum specifies a different threshold. This pre-approval requirement means that a buyer cannot complete an acquisition of an OOD interest without the cooperation of the existing members - a structural feature that is sometimes used as a defensive mechanism by incumbent shareholders.

Due diligence for Bulgarian corporate acquisitions must cover several layers that are not always visible from the Commercial Register alone: pending litigation (checked through the court information system), tax liabilities (checked through the National Revenue Agency, Национална агенция за приходите, НАП), environmental obligations, and employment law compliance. A non-obvious risk is that Bulgarian law does not provide for a general statutory warranty regime in share purchase agreements - all warranties and indemnities must be expressly negotiated and drafted.

The Competition Protection Act (Закон за защита на конкуренцията, ЗЗК) requires notification to the Commission for Protection of Competition (Комисия за защита на конкуренцията, КЗК) for transactions that meet the applicable turnover thresholds. The review period at Phase I is 25 working days from the date of complete notification. Failure to notify a notifiable transaction is a serious regulatory violation and can result in fines calculated as a percentage of the parties' annual turnover.

Post-acquisition integration in Bulgaria frequently surfaces governance gaps that were not identified during due diligence. Common issues include undocumented related-party transactions, managers with undisclosed conflicts of interest, and constitutional documents that have not been updated to reflect years of informal practice. Addressing these issues promptly after closing reduces the risk of shareholder disputes and regulatory exposure.

What is the most significant practical risk when structuring a 50/50 joint venture in Bulgaria?

The most significant risk is deadlock at the general meeting level, which the Commerce Act does not resolve through a statutory mechanism. Without a contractual deadlock resolution provision in the shareholders agreement - such as a buy-sell clause or a casting vote arrangement - either party can paralyse the company indefinitely. The only statutory remedy is a court application for the appointment of a temporary manager, which is slow and does not resolve the underlying ownership dispute. Structuring the shareholders agreement with a clear, time-bound deadlock mechanism before incorporation is the most effective mitigation. Choosing arbitration as the dispute resolution forum for the shareholders agreement adds an additional layer of enforceability.

How long does a corporate dispute typically take to resolve in Bulgarian courts, and what are the realistic costs?

A first-instance corporate dispute before a Bulgarian district or regional court typically takes between 12 and 24 months, depending on the complexity of the case and the court's caseload. Appeals to the Court of Appeal (Апелативен съд) add a further 6 to 18 months, and a cassation appeal to the Supreme Court of Cassation (Върховен касационен съд, ВКС) can extend the total timeline to 4 or 5 years. Legal fees for a contested corporate dispute start from the low thousands of EUR for straightforward matters and can reach the mid-to-high tens of thousands for complex multi-party cases. State court fees are proportional to the claim value. For disputes with a clear monetary value above EUR 50,000, litigation is generally economically viable; below that threshold, negotiated settlement or arbitration is often more efficient.

When should a foreign investor choose arbitration over Bulgarian state courts for corporate disputes?

Arbitration is preferable when the dispute involves a foreign counterparty, when confidentiality is commercially important, or when the parties want a tribunal with experience in international commercial matters. The Arbitration Court at the Bulgarian Chamber of Commerce and Industry is a well-established institution with procedural rules that allow for efficient case management. However, arbitration is not available for all corporate law matters: challenges to general meeting resolutions, insolvency proceedings, and certain registration disputes must go to the state courts. A well-drafted dispute resolution clause in the shareholders agreement should therefore specify arbitration for contractual claims between shareholders and state courts for statutory corporate law claims, avoiding jurisdictional ambiguity.

Bulgarian corporate law provides a functional and EU-compliant framework for international business, but it contains specific procedural requirements, governance obligations, and liability rules that differ from the norms familiar to investors from Western Europe or common law jurisdictions. The gap between formal legal compliance and effective governance is where most disputes originate. Addressing that gap at the formation stage - through well-drafted constitutional documents, a robust shareholders agreement, and clear governance protocols - is substantially less costly than resolving disputes after they arise.
