Legal Systems of the World 

Civil Law

Civil law is the most prevalent system of law throughout the world including much of Europe and South America. Authority is driven by core principles that are codified into a referable system. This may be a constitution or statute passed by a legislature. Civil law is also known as Continental European law.

Common Law

Common law is also known as case law or precedent. A decision made by a judge in a court of law binds future decisions to be made by the same reasoning. Lawyers and judges refer to decisions made in previous cases in order to make a point. About one-third of the world uses common law including the United States, Canada, and Australia. 

Religious Law

Religious law uses a religious system or document as the source of the law. It is used in Vatican City and other religious states. 

Pluralistic Systems

Pluralistic systems combine the aspects of two or more types of law. India, for example, combines civil, common, and religious law. 

Types of Law

Intellectual Property Law

Intangible assets such as discoveries, inventions, words, phrases, symbols, designs, and literary, musical, and artistic works can be protected by obtaining exclusive rights.  Intellectual property lawyers acquire and enforce such protection.  Intellectual property can be protected with patents, trademarks, and copyrights.

A patent gives exclusive rights to an inventor or assignee for a limited time period after details about the object are publicly filed. The term "patent pending" warns potential infringers that an application is in process. In the United States patents are issued by the Patent and Trademark Office (PTO), an agency of the U.S. Department of Commerce, which issued its 8,000,000th patent in 2011.

A trademark is a brand name and may consist of a word, name, symbol, or device used to distinguish an organization's products or services. It is indicated by the use of one of three symbols: TM, ?, or ®.

Copyright gives a creator the exclusive right to limit others from copying the work for a limited period of time. A copyright t is a personal property that can be willingly passed, bought, or sold by the owner. The copyright notice may be indicated by a symbol ©, the word "Copyright" or the abbreviation "Copr." Sound recording copyright is indicated with a symbol ?.

Some patent lawyers have undergraduate degrees in science or engineering to better understand the products or services being protected.

Legal Support  

Expert Witnesses

An expert witness, also known as a professional witness or judicial expert, is someone with specialized knowledge of a subject.  An expert witness is someone who has gained expertise through education, training, skill, or experience. The knowledge an expert witness has about a particular subject is beyond that of the average person.  Expert witnesses include scientists, engineers, insurance adjusters, and accident reconstructionists.

The knowledge of an expert witness may be officially relied on to form an opinion about a piece of evidence or a fact.  An expert witness may be called upon to:

  • Determine the cause of failure in a device.
  • Give an opinion on the severity of an injury.
  • Compare two items to ascertain their degree of similarity in intellectual property cases.

Legal software products are used in the legal profession to automate processes, create forms, and to access court databases and other related applications.  


The terms lawyer and attorney are used interchangeably in the United States.  A lawyer is a person that has been trained in the law but may not be practicing while an attorney was trained and is a practitioner of the court.
