For international investors and counsel, the legal landscapes of the Democratic Republic of Congo (DRC) and the Republic of Congo (Congo-Brazzaville) can appear complex and daunting. However, a powerful unifying thread simplifies commercial law across both nations and 15 others: the Organization for the Harmonization of Business Law in Africa (OHADA).
For a smart lawyer, understanding OHADA is not just an academic exercise; it is the master key to providing effective, strategic, and risk-mitigating legal advice for clients operating in these two dynamic economies. This article breaks down the essentials and highlights critical areas for counsel.

17 OHADA Countries
OHADA: The Common Legal Bedrock
First, a crucial point of clarification: both the DRC and Congo-Brazzaville are full-fledged members of OHADA. This means that OHADA Uniform Acts are directly applicable and supreme over national commercial laws within both countries.
For legal practitioners, this is a significant advantage. Instead of navigating two entirely separate commercial codes, you are working primarily from a single, harmonized set of rules. This reduces the learning curve for multi-jurisdictional operations and provides a layer of predictability.

Core OHADA Acts: Where to Focus Your Counsel
While all ten OHADA Uniform Acts are relevant, your advice for clients in the DRC and Congo will most frequently engage the following:
Uniform Act on Commercial Company Law and Economic Interest Grouping (AUSCGE):
Entity Selection: Advise on the most suitable corporate vehicle (e.g., SARL for limited liability, SA for public offerings). The rules are uniform, but local practices and registration processes (through the Guichet Unique in each country) have nuances.
Corporate Governance: Counsel on director liabilities, shareholder meetings, and capital increases/reductions as per the Uniform Act. Ensure compliance is locked at the OHADA level first.
Uniform Act on Securities (AUD):
Securing Transactions: This is a critical area for risk management. The Act modernizes securities, moving beyond traditional mortgages to include non-possessory pledges over equipment, inventory, and receivables.
Actionable Advice: Prioritize helping clients create enforceable security interests registered with the OHADA Registry (Registre du Commerce et du Crédit Mobilier - RCCM). This is often a lender's primary safeguard.

Beyond OHADA: The Crucial National Layer
A smart lawyer never advises on OHADA in a vacuum. The framework coexists with robust layers of national law that you must integrate into your advice.
In the DRC: The Code des Investissements offers potential incentives. Labor law, tax law, real estate law, and mining code regulations (Code Minier) are profoundly important and purely national. The constitutional court structure and general judicial organization are specific to the DRC.
In Congo-Brazzaville: Similarly, national investment codes, petroleum laws (Code Pétrolier), tax regulations, and labor codes apply alongside OHADA laws. Understanding the local implementation of the Guichet Unique for business creation is essential.
Practical Strategy:
Your advice should follow a two-tiered approach: first, apply the OHADA framework, and then layer on the specific national requirements of the DRC or Congo-Brazzaville for taxes, sector-specific regulations, and land rights.
Strategic Recommendations for Legal Practitioners
Start with OHADA: Frame your initial legal analysis through the OHADA lens. It provides the solid, predictable foundation.
Prioritize Arbitration: Make CCJA arbitration the default dispute resolution mechanism in every commercial contract you draft. This is perhaps the single most important piece of advice for protecting your client.
Conduct Dual Due Diligence: When performing legal due diligence, you must investigate compliance with both relevant OHADA Acts and national laws. For example, a company's incorporation must be checked against the AUSCGE and its registration at the local RCCM.
Monitor Jurisprudence: Follow the rulings of the CCJA, the supreme interpreter of OHADA law. Its case law is binding on national courts in both the DRC and Congo and is essential for understanding how the Uniform Acts are applied.
Build Local Partnerships: The practical implementation of laws—especially at the national level—requires on-the-ground expertise. Partnering with a trusted local law firm in Kinshasa or Brazzaville is indispensable for navigating administrative procedures, court systems, and regulatory bodies.
Conclusion
For the DRC and Congo-Brazzaville, OHADA is the great harmonizer, offering a modern and predictable commercial law system. For lawyers, it is a powerful tool that, when mastered, demystifies much of the legal complexity in these jurisdictions.
The most effective legal advice strategically leverages the uniformity of OHADA—especially its arbitration and secured transactions regimes—while diligently accounting for the critical overlay of national regulations. By doing so, you provide your clients with a robust legal framework for success, turning perceived complexity into a competitive advantage.
