Common Law vs. Civil Law: Understanding Global Legal Systems

Legal frameworks around the world can broadly be categorized into two main systems: common law and civil law. Understanding the differences between these two systems is crucial for navigating international business and maintaining compliance across borders.

Origins of Common Law & Civil Law

Common Law
Common law originated in England during the Middle Ages and became the foundation for legal systems in former British colonies, such as the United States (except Louisiana), Canada (except Quebec), Australia, India and parts of Africa. Common law evolves through court decisions and judicial precedents, providing a flexible, case-based approach to interpreting laws.

Civil Law
Civil law, on the other hand, was developed in continental Europe and spread through colonial powers like Spain, Portugal and France. It emphasizes codified statutes and legal frameworks. Countries in South America, continental Europe and regions influenced by Napoleonic law or Spanish rule operate primarily under civil law systems. Unlike common law, civil law relies less on judicial interpretation and more on written codes and statutes.‍

Key Differences in Practice

Tax and Company Registration
A notable example of how these systems diverge can be seen when comparing the UK (common law) and Spain (civil law). In the UK, registering a company requires submitting forms like the IN01 to Companies House, a centralized registry, and can be completed within a week. In Spain, however, the process involves multiple filings, often region-specific, and can take up to two months. Additionally, Spain requires a tax representative, whereas the UK does not. These differences highlight the administrative complexity civil law countries often have compared to their common law counterparts.


Centralized vs. Decentralized Registries

Common law systems typically rely on centralized registries, simplifying processes like company formation and record searches. Civil law systems, however, often require multiple filings at district, regional or federal levels. For instance, while civil law countries like Spain may have localized tax filing systems, they often still maintain centralized registries for record searches. In Canada, which blends elements of common and civil law, companies can register federally but may also need to register at the provincial or territorial level for localized operations.

Systemic Trends & Implications

Neither system is inherently superior, but they reflect differing approaches to governance and legal administration. Common law’s reliance on judicial precedents allows for flexibility but may require deeper legal analysis for decisions. Civil law’s codified statutes create predictability but may involve more bureaucratic processes. For businesses operating internationally, understanding these systemic differences is key to avoiding delays, reducing risks and ensuring compliance.
