The main branches of business law
Company law is an important branch of business law. It includes all the rules governing the creation, operation and dissolution of private law companies.
The competition law is another branch, almost as important: it defines the relationships between economic agents in their reports to the market. It strives to enforce competition and prohibits practices deemed anti-competitive. French competition law is today heavily dependent on the European Union's competition law.
The law of insolvency proceedings relates to judicial reorganization or liquidation procedures. It defines the rules to be respected between the creditors and the company in difficulty (debtor).
The banking law that governs banking and exchange law , which brings together the rules applicable to commercial paper, is also part of business law.
Finally, intellectual property law, consumer law, securities law, insurance law, financial law, etc., could be mentioned.
Business law is very broad, to say the least! It is obviously not possible to have a synoptic view of all business law. Even lawyers in business law do not know everything: they are usually specialized in a branch of business law.
On the other hand, it is strongly advised to take knowledge of the main rules of the law of the businesses which concern your activity. For example, company law if you want to start a business, manage it in the rules, and so on.
