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.

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.
