Query: How many countries in the world use common law?
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
The law of most of the states is based on the common law of England; the notable exception is Louisiana, whose civil law is largely based upon French and Spanish law. The passage of time has led to state courts and legislatures expanding, overruling, or modifying the common law; as a result, the laws of any given state invariably differ from the laws of its sister states. Thus, as noted above, the U.S. must be regarded as 50 "separate" systems of tort law, family law, property law, contract law, criminal law, and so on. (In addition, the District of Columbia and the federal territories also have their own separate legal systems analogous to state legal systems, although they do not enjoy state sovereignty.)
The common lawso named because it was "common" to all the king's courts across Englandoriginated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066. The British Empire spread the English legal system to its historical colonies, many of which retain the common law system today. These "common law systems" are legal systems that give great precedential weight to common law, and to the style of reasoning inherited from the English legal system.
Common law originated from England and has been inherited by almost every country once tied to the British Empire (except Malta, Scotland, the U.S. state of Louisiana, and the Canadian province of Quebec). In medieval England, the Norman conquest the law varied-shire-to-shire, based on disparate tribal customs. The concept of a "common law" developed during the reign of Henry II during the late 12th century, when Henry appointed judges that had authority to create an institutionalized and unified system of law "common" to the country. The next major step in the evolution of the common law came when King John was forced by his barons to sign a document limiting his authority to pass laws. This "great charter" or "Magna Carta" of 1215 also required that the King's entourage of judges hold their courts and judgments at "a certain place" rather than dispensing autocratic justice in unpredictable places about the country. A concentrated and elite group of judges acquired a dominant role in law-making under this system, and compared to its European counterparts the English judiciary became highly centralized. In 1297, for instance, while the highest court in France had fifty-one judges, the English Court of Common Pleas had five. This powerful and tight-knit judiciary gave rise to a systematized process of developing common law.
Federal common law is a term of United States law used to describe common law that is developed by the federal courts, instead of by the courts of the various states. The United States is the only country to combine the creation of common law doctrines with a complete federalism, wherein the national supreme court has virtually no power to review state court decisions to determine whether the state courts have followed state laws. The High Court of Australia is sometimes said to have federal common law, but because all state and territorial courts are directly appealable to the High Court, this is indistinguishable from a general common law. In contrast, the United States Supreme Court has effectively barred the creation of federal common law in areas traditionally under the authority of state courts. Nevertheless, there are several areas where federal common law continues to govern.
In common law legal systems, precedent is a principle or rule established in a previous legal case that is either binding on or persuasive for a court or other tribunal when deciding subsequent cases with similar issues or facts. Common-law legal systems place great value on deciding cases according to consistent principled rules, so that similar facts will yield similar and predictable outcomes, and observance of precedent is the mechanism by which that goal is attained. The principle by which judges are bound to precedents is known as stare decisis. Common-law precedent is a third kind of law, on equal footing with statutory law (that is, statutes and codes enacted by legislative bodies) and delegated legislation (in U.K. parlance) or regulatory law (in U.S. parlance) (that is, regulations promulgated by executive branch agencies).
The common lawso named because it was "common" to all the king's courts across Englandoriginated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066. Prior to the Norman Conquest, much of England's legal business took place in the local folk courts of its various shires and hundreds. A variety of other individual courts also existed across the land: urban boroughs and merchant fairs held their own courts, as did the universities of Oxford and Cambridge, and large landholders also held their own manorial and seigniorial courts as needed. Additionally, the Catholic Church operated its own court system that adjudicated issues of canon law.
Today, domestic common law marriages can be contracted in the following nine jurisdictions:Additionally, these two jurisdictions recognise domestic common law marriage in the limited circumstances indicated:Of the remaining 40 states, 13 never permitted and 27 no longer permit common law marriages to be contracted within their jurisdiction. The latter group will only recognise a domestic common law marriage if it was contracted in the state prior to the date of abolition. Nevertheless, all states recognise validly contracted "foreign" common law marriages, because they recognise all validly contracted foreign marriages. E.g. California abolished the common law contract of marriage in 1895 and, thus, will only continue to recognise a domestic common law marriage contracted in California prior to that date; but any validly contracted "out-of-state" common law marriage will be recognised by California, because it recognises "all" validly contracted foreign marriages under Cal. Family Code 308.
As used by non-lawyers in popular culture, the term "common law" connotes law based on ancient and unwritten universal custom of the people. The "ancient unwritten universal custom" view was the view among lawyers and judges from the earliest times to the mid-19th century. But for 100 years, lawyers and judges have recognized that the "ancient unwritten universal custom" view does not accord with the facts of the origin and growth of the law, and it is not held within the legal profession today.
Under the modern view, “common law” is not grounded in “custom” or "ancient usage", but rather acquires force of law instantly (without the delay implied by the term "custom" or "ancient") when pronounced by a higher court, because and to the extent the proposition is stated in judicial opinion. From the earliest times through the late 19th century, the dominant theory was that the common law was a pre-existent law or system of rules, a social standard of justice that existed in the habits, customs, and thoughts of the people. Under this older view, the legal profession considered it no part of a judge's duty to make new or change existing law, but only to expound and apply the old. By the early 20th century, largely at the urging of Oliver Wendell Holmes (as discussed throughout this article), this view had fallen into the minority view: Holmes pointed out that the older view worked undesirable and unjust results, and hampered a proper development of the law. In the century since Holmes, the dominant understanding has been that common law “decisions are themselves law, or rather the rules which the courts lay down in making the decisions constitute law”. Holmes wrote in a 1917 opinion, “The common law is not a brooding omnipresence in the sky, but the articulate voice of some sovereign or quasi sovereign that can be identified." Among legal professionals (lawyers and judges), the change in understanding occurred in the late 19th and early 20th centuries (as explained later in this article), though lay dictionaries were decades behind in recognizing the change.
Examples of common law being replaced by statute or codified rule in the United States include criminal law (since 1812, U.S. federal courts and most but not all of the States have held that criminal law must be embodied in statute if the public is to have fair notice), commercial law (the Uniform Commercial Code in the early 1960s) and procedure (the Federal Rules of Civil Procedure in the 1930s and the Federal Rules of Evidence in the 1970s). But note that in each case, the statute sets the general principles, but the interstitial common law process determines the scope and application of the statute.
Customary law is also used in some Third World countries, such as those in Africa, usually used alongside common or civil law. For example, in Ethiopia, despite the adoption of legal codes based on civil law in the 1950s according to Dolores Donovan and Getachew Assefa there are more than 60 systems of customary law currently in force, "some of them operating quite independently of the formal state legal system." They offer two reasons for the relative autonomy of these customary law systems: one is that the Ethiopian government lacks sufficient resources to enforce its legal system to every corner of Ethiopia; the other is that the Ethiopian government has made a commitment to preserve these customary systems within its boundaries.
All U.S. jurisdictions recognize common-law marriages that were validly contracted in the originating jurisdiction, because they are valid marriages in the jurisdiction where they were contracted, because of the Full Faith and Credit Clause. However, absent legal registration or similar notice of the marriage, the parties to a common law marriage or their eventual heirs may have difficulty proving their relationship to be marriage. Some states provide for registration of an informal or common-law marriage based on the declaration of each of the spouses on a state-issued form.

The actual substance of English law was formally "received" into the United States in several ways. First, all U.S. states except Louisiana have enacted "reception statutes" which generally state that the common law of England (particularly judge-made law) is the law of the state to the extent that it is not repugnant to domestic law or indigenous conditions. Some reception statutes impose a specific cutoff date for reception, such as the date of a colony's founding, while others are deliberately vague. Thus, contemporary U.S. courts often cite pre-Revolution cases when discussing the evolution of an ancient judge-made common law principle into its modern form, such as the heightened duty of care traditionally imposed upon common carriers.
Domestic contract of common law marriage was abolished in the following 27 states on the dates indicated. Note that Massachusetts (which included Maine, 1652 - 1820) abolished common law marriage during the colonial period and before it was abolished in England and Wales.These 13 states have never permitted domestic common law marriage; but like all 50 states and the District of Columbia, they recognise all validly contracted out-of-state marriages, including validly contracted common law marriages.Outside of confederation, the Territory of Guam does not recognise common law marriage. The Commonwealth of the Northern Mariana Islands also does not recognise common law marriage but "might" recognise customary marriage. In "Santos v. Commonwealth", Petitioner argued that common law marriage was sufficiently similar to Carolinian customary marriage that it should be recognised as the same. The Court ruled that, while CNMI statute provides that (English) common law provides the rule of decision in the absence of statutory law "or" customary law to the contrary, Petitioner did not argue that her marriage was a marriage under "customary" law but a marriage under "common law"; thus, whereas a validly contracted marriage under Carolinian or Chamorro customary law might be held a valid marriage, a common law marriage could "not" be.
A reception statute is a statutory law adopted as a former British colony becomes independent, by which the new nation adopts (i.e. receives) pre-independence common law, to the extent not explicitly rejected by the legislative body or constitution of the new nation. Reception statutes generally consider the English common law dating prior to independence, and the precedent originating from it, as the default law, because of the importance of using an extensive and predictable body of law to govern the conduct of citizens and businesses in a new state. All U.S. states, with the partial exception of Louisiana, have either implemented reception statutes or adopted the common law by judicial opinion.
Northern Ireland law refers to the legal system of statute and common law operating in Northern Ireland since the partition of Ireland established Northern Ireland as a separate jurisdiction within the United Kingdom in 1921.
For the purposes of private international law the United Kingdom is divided into three distinct legal jurisdictions:Northern Ireland is a common law jurisdiction. Although its common law is similar to that in England and Wales, and partially derives from the same sources, there are some important differences in law and procedure between Northern Ireland and England and Wales. While influenced by English law, the Northern Ireland legal system is distinctive for a number of reasons: it has roots in Irish common law prior to Irish independence in 1921; following Irish independence, Northern Ireland became a devolved jurisdiction within the United Kingdom.
In general, a Commonwealth citizen is a citizen of a member state of the Commonwealth of Nations. This designation is given legal effect in the nationality laws of some Commonwealth countries, and Commonwealth citizens may enjoy some privileges in the United Kingdom and, less commonly, other member states. Each Commonwealth country determines what special rights, if any, are accorded to citizens of other Commonwealth countries. The status is most significant in British law and has little effect in many other Commonwealth countries, such as Australia.
Commonwealth is a designation used by four of the 50 states of the United States in their full official state names: Kentucky, Massachusetts, Pennsylvania, and Virginia. Commonwealth is a traditional English term for a political community founded for the common good. Prior to the formation of the United States of America in 1776, all four were part of Great Britain's possessions along the Atlantic coast of North America. As such, they share a strong influence of English common law in some of their laws and institutions.
Yet, adoption of the common law in the newly-independent nation was not a foregone conclusion, and was controversial. Immediately after the American Revolution, there was widespread distrust and hostility to anything British, and the common law was no exception. Jeffersonians decried lawyers and their common law tradition as threats to the new republic. The Jeffersonians preferred a legislatively-enacted civil law under the control of the political process, rather than the common law developed by judges that—by design—were insulated from the political process. The Federalists believed that the common law was the birthright of Independence: after all, the natural rights to "life, liberty, and the pursuit of happiness" were the rights protected by common law. Even advocates for the common law approach noted that it was not an ideal fit for the newly-independent colonies: judges and lawyers alike were severely hindered by a lack of printed legal materials. Before Independence, the most comprehensive law libraries had been maintained by Tory lawyers, and those libraries vanished with the loyalist expatriation, and the ability to print books was limited. Lawyer (later president) John Adams complained that he "suffered very much for the want of books". To bootstrap this most basic need of a common law system—knowable, written law—in 1803, lawyers in Massachusetts donated their books to found a law library. A Jeffersonian newspaper criticized the library, as it would carry forward "all the old authorities practiced in England for centuries back ... whereby a new system of jurisprudence [will be founded] on the high monarchical system [to] become the Common Law of this Commonwealth... [The library] may hereafter have a very unsocial purpose."
During the 15th century, the common law courts were challenged by the civil law and equity found in the Chancery and similar courts. These courts and legal methods were much faster than the common law courts, so lawyers and claimants flocked to them. This was perceived as a threat to the common law courts, for good reason; between 1460 and 1540, the business of the common law courts significantly dropped, while the Chancery's cases rose massively in number. In reaction to this, the Court of King's Bench developed its own, faster system, intent on winning cases back, and through procedures such as the Writ of Quominus and Bill of Middlesex acquired a wider jurisdiction. While this succeeded in forming an equilibrium between the old common law courts and the new courts, it was viewed with suspicion by the Common Pleas, who became highly reactionary to the changes the King's Bench attempted to introduce. When the King's Bench attempted to use the Bill of Middlesex to widen its jurisdiction, the Common Pleas became increasingly conservative in its attempts to avoid ceding cases. This was limited by the fact that the three Common Pleas prothonotaries could not agree on how to cut costs, leaving the court both expensive and of limited malleability while the King's Bench became faster, cheaper and more varied in its jurisdiction.

Worldwide, 178 countries have at least one official language, and 101 of these countries recognise more than one language. Many of the world's constitutions mention one or more official or national languages. Some countries use the official language designation to empower indigenous groups by giving them access to the government in their native languages. In countries that do not formally designate an official language, a "de facto" national language usually evolves. English is the most common official language, with recognized status in 51 countries. Arabic, French, and Spanish are also widely recognized.
In civil cases many trials require fewer than twelve jurors. Juries are almost never used in civil cases outside the United States and Canada. Other states with a common law tradition sometimes use them in defamation cases, in cases involving a governmental eminent domain power, and in cases involving alleged wrongful conviction. Civil law countries generally do not use civil juries. Civil juries are available in the United States and Canada in almost all cases where the only remedy sought is money damages.
Today, one-third of the world's population lives in common law jurisdictions or in systems mixed with civil law, including Antigua and Barbuda, Australia, Bahamas, Bangladesh, Barbados, Belize, Botswana, Burma, Cameroon, Canada (both the federal system and all its provinces except Quebec), Cyprus, Dominica, Fiji, Ghana, Grenada, Guyana, Hong Kong, India, Ireland, Israel, Jamaica, Kenya, Liberia, Malaysia, Malta, Marshall Islands, Micronesia, Namibia, Nauru, New Zealand, Nigeria, Pakistan, Palau, Papua New Guinea, Sierra Leone, Singapore, South Africa, Sri Lanka, Trinidad and Tobago, the United Kingdom (including its overseas territories such as Gibraltar), the United States (both the federal system and 49 of its 50 states), and Zimbabwe. Some of these countries have variants on common law systems.
