When studying the different legal disciplines is also desirable to explore areas of law that covers up or which order to understand the importance of the branch of law or field of study mentioned. It is in this vein that we will study the branches of business law to take a comprehensive approach to this branch of law, which from a certain approach is not a field of law but an area of law. The branches and areas that are part of corporate law are: civil law heritage, commercial, corporate, or cartular exchange, securities, bankruptcy formerly known as bankruptcy law, labor, tax, registration, notarial, criminal enterprise, economic constitution, bank, cooperative, civil procedure, customs, industrial, insurance, industrial property (patents, trademarks, etc.) and competition law, trademark, social security, contractual, mining, commercial arbitration and negotiation, business contracts modern, warrants, the supervisory bodies (levy), economic regulation and industrial organization, transport infrastructure, electronic commerce, transport law, corporate responsibility, telecommunications, sanitation, electricity sector economy, oil and electricity, private international law and regulation of the electricity sector.

These are also areas of the law of corporate law, commercial law and some. That is, note that these areas of law covering  almost every right, in this sense can not deny its importance and involving substantial part of it. Corporate law is not the same as the corporate law, but cover the same areas of law in this regard when considering studying business law corporate law. One of the characteristics of corporate law is that it covers quite a few areas of law, which also occurs in the case of corporate law, but not in the case of commercial law, since the latter covers a few areas of law that are corporate, cartular or exchange, securities, bankruptcy, telecommunications, defense of competition, banking, insurance and reinsurance, trademark, among others. In this sense we can say that commercial law is more narrow than the corporate law and corporate law. And the first part of the latter. Only by studying the branches of business law can understand the true importance.

This also will be subject of study corporate law, so then we will refer to it. Corporate law is the branch of law regulating the business of large companies or corporations. This branch of law has developed very little in the Peruvian law and that its development has generally been in the business law and in any case it is clear that corporate law appears after the right business. That is, the corporate law is not the same as the corporate law in this regard have some differences, which we refer then to take a comprehensive approach to the subject matter of study and not be misled by approaches Partial.
When differences should conduct research areas of law that are similar to avoid confusion and to enable investigations to be more reliable and we can better serve our purposes. The difference in corporate law corporate law that regulates and examines the first large companies only while the second does the same for all companies whatever their size or importance. In this sense we can say that studying business law and regulates all companies, ie micro-enterprises, small businesses, medium businesses, large businesses or corporations. However, the difference is not only the size but also areas of law involved, such as corporate law is characterized by covering the securities, which although it is also covered by corporate law, but we do own the right corporate.
The business law is different from commercial law in the first covers the second, in this regard commercial law is a part of business law. However, few understand this difference and studying both like the same but with another name, which is necessary to take into account the effect of warning for error, since they are not the same and even appear in different periods of time. That is, are not the same as referring to different topics, so it is clear that commercial law is part of business law.
