Civil law and common law are two different legal systems used by countries worldwide. Common law, also known as case law, is a system that originated in medieval England and is based on judicial precedent. It is used in countries that were formerly under English rule, including the United States, the United Kingdom, and former British colonies. Civil law, on the other hand, is a comprehensive, codified set of legal statutes created by legislators and is influenced by Roman law. Civil law is prevalent in countries that were former French, Dutch, German, Spanish, or Portuguese colonies, as well as in Central and South America and much of continental Europe. While common law relies on judicial decisions and interpretations, civil law countries have more detailed written laws and rely less on the opinions of judges.

Common law is based on judicial precedent, not written law
Common law is a body of unwritten laws based on legal precedents established by the courts. It is often contrasted with civil law, which takes the form of legal codes. Common law originated in medieval England, while civil law has its roots in Rome and Napoleonic France.
Common law is based on the principle of stare decisis, which means "to stand by things decided." In other words, it relies on a history of judicial decisions or precedents to form the basis of evaluation for future cases. This means that past court decisions are recognised as legally binding precedents. For example, in Mr. Shears' case in Oklahoma, there was no written law stating that a DUI conviction could result in disbarment. However, a prior court decision ruled that a DUI conviction "in and of itself does not show unfitness to practice law." This precedent influenced the outcome of Mr. Shears' case, demonstrating the power of stare decisis in common law.
In common law systems, judges play a crucial role in shaping the law. They can interpret and apply precedents to the specific circumstances of a case, and their decisions are generally binding. While lower courts follow the example set by higher courts, they have some flexibility to modify or deviate from precedents if they are outdated or if the current case is substantially different. However, overturning precedents is rare. This feature of common law allows for stability and consistency in the legal system.
Unlike civil law, common law is not based on a comprehensive set of written rules or codes. Instead, it relies on case law and judicial opinions to establish standards of interpretation and consistent outcomes. This means that common law systems are less prescriptive, and there is more freedom of contract. Contracts in common law tend to be more detailed, as all terms governing the relationship between the parties must be explicitly stated.
In summary, common law is based on the principle of stare decisis, where judicial precedent and institutionalised opinions shape future decisions. It is an unwritten body of law that adapts and evolves through judicial interpretation, distinguishing itself from civil law's reliance on written legal codes.

Civil law is a codified system of law, originating from Roman law
Civil law is a comprehensive, codified system of law, meaning it takes the form of written legal codes. It is a major branch of the law, in common law legal systems such as those in England, Wales, and the United States, where it stands in contrast to criminal law. Civil law is regularly updated, but the goal of standardized codes is to create order and reduce bias in the system.
Civil law is distinct from common law, which is based on unwritten laws and legal precedents established by the courts. Common law, also known as case law, relies on detailed records of similar situations and statutes because there is no official legal code that can be directly applied to a case. The judge presiding over a case determines which precedents apply to that particular case. While civil law is a more prescriptive system, common law is less prescriptive and more flexible, allowing for the creation of new laws that are relevant to the present.
The civil law system has its origins in Roman law, with the ancient Romans developing civil law in a very sophisticated manner. The Code of Justinian was based on Roman civil law, and the Code of Canon Law of the Catholic Church is also based on civil law. Civil law countries include Germany, France, Italy, and much of Central and South America, as well as most of Central and Eastern European and East Asian countries. These countries were often former French, Dutch, German, Spanish, or Portuguese colonies or protectorates.
In contrast, common law countries include the United States, the United Kingdom, and other countries that were formerly under English rule. Common law originated in medieval England and is characterized by judicial decisions that are legally binding and can shape future rulings. While common law is not as widely used in the United States, it is still the system used in 49 states and the federal government.

Common law countries have more freedom of contract
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. Countries following a common law system are typically former British colonies or protectorates, including the United States. Common law systems have extensive freedom of contract, with few provisions implied into a contract by law. This means that all the terms governing the relationship between the contracting parties must be set out in the contract itself, which can result in longer contracts compared to those in civil law countries.
Civil law, on the other hand, is a comprehensive, codified set of legal statutes created by legislators. Civil law countries typically include former French, Dutch, German, Spanish, or Portuguese colonies or protectorates, as well as much of Central and South America, Central and Eastern Europe, and East Asia. Civil law systems imply many provisions into a contract, and parties cannot contract out of certain provisions. This results in shorter contracts, as less importance is placed on enumerating all the terms in the contract itself since inadequacies or ambiguities can be resolved by operation of law.
In common law systems, judicial decisions are binding, and decisions of the highest court can generally only be overturned by that same court or through legislation. This promotes stability and consistency in the legal system. Lower courts can deviate from precedents if they are outdated or if the current case is substantially different. However, this has led to unfair marginalization or disempowerment of certain groups, as past decisions continue to shape future rulings until societal changes prompt a judicial body to overturn the precedent.
While common law provides more freedom of contract, there are still regulations that must be adhered to in certain areas, such as employment, tenancy, and sales of goods. Additionally, in modern common-law countries, there is an increasing use of "contracts of adhesion" or form contracts, which may benefit stronger parties by forcing terms onto weaker parties. Despite this, common law countries generally allow for more flexibility and customization in contracts, as long as the terms do not expressly violate the law.
In summary, common law countries provide more freedom of contract by allowing parties to set out the majority of the terms of their agreement, as opposed to civil law countries, where many provisions are implied by law. This distinction results in longer contracts in common law countries and shorter contracts in civil law countries.

Civil law countries have more detailed laws, relying less on judge's opinions
Civil law and common law are two different legal systems that are used in different parts of the world. Common law is a body of unwritten laws based on legal precedents established by the courts. It originated in medieval England and is often contrasted with civil law, which takes the form of legal codes such as the Napoleonic Code. Common law recognises prior court decisions as legally binding precedents, also known as stare decisis. In common law countries, judges can make laws in certain areas, and the legal system relies on the opinions of judges to a greater extent than civil law systems.
Civil law, on the other hand, is a comprehensive, codified set of legal statutes created by legislators. It is based on legal codes and is generally more prescriptive than common law. Civil law countries have more detailed laws that are created by the legislature, and they rely less on the opinions of judges. Instead, a court in a civil law country is required to follow the legal code as written by the legislator. While a court's interpretation of a legal code is not binding, and the court may later interpret the law differently, the law itself is not based on judicial opinion or precedent.
Civil law is used in many former French, Dutch, German, Spanish, and Portuguese colonies or protectorates, including much of Central and South America, Central and Eastern Europe, and East Asia. Common law, meanwhile, is used in countries that were formerly under English rule, including the United States (except Louisiana, which uses civil law) and the United Kingdom.
The difference between the two legal systems can be seen in the way contracts are handled. In common law countries, contracts tend to be longer because all the terms governing the relationship between the parties must be set out in the contract itself. In civil law countries, many provisions are implied into a contract by law, and less importance is placed on setting out all the terms in the contract. This often results in shorter contracts.
In summary, civil law countries have more detailed laws created by the legislature and rely less on the opinions of judges, while common law countries have less detailed, unwritten laws that are based on judicial precedents and rely more heavily on the opinions of judges.

Common law countries base their legal systems on medieval England
Common law and civil law are two distinct legal systems that countries around the world follow. Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. Common law originated in medieval England and is followed by countries that were formerly British colonies or protectorates, including the United States, the United Kingdom, and several other countries.
In common law countries, judges play a significant role in shaping the law by setting precedents that guide future cases. Judicial decisions are considered binding, and higher court rulings are generally only overturned by those same higher courts or through legislation. This system allows for flexibility and the evolution of the law over time.
In contrast, civil law is a comprehensive, codified set of legal statutes created by legislators. It is based on legal codes and takes its origins from Roman law and Napoleonic France. Civil law is prevalent in former French, Dutch, German, Spanish, or Portuguese colonies, including much of Central and South America, Central and Eastern European countries, and East Asian countries.
Civil law provides a clear framework for resolving disputes, defining the cases that can be brought to court, the procedures for handling claims, and the punishments for offenses. It aims to create order and reduce bias by standardizing the application of laws. While civil law is regularly updated, the standardized codes help ensure consistent outcomes across cases.
While common law countries share similarities due to their roots in medieval England, local variations and unique influences have led to differences in their legal systems over time. Common law countries may have differences in their approaches to contract law, tort law, and other areas of law based on their specific judicial precedents and interpretations.
