One of the basic missions of the European Union is to provide equal rights to everyone within the Union, i.e. to establish an internal market by ensuring basic freedoms. In the area of company law , the prerequisites for adopting EU initiatives include easier access to the freedom of establishment of companies and the legal regulation of relationships between subjects of company law (companies). The European company is a company and a legal person, and it is considered to be a supranational form of a company, with the goal of enabling a company with the seat in one of the member states of the Union to conduct unobstructed business activities in the entire European Union, also, the company should have a certain status in every member state and it should be treated like it was established and like it has seat in that state. Companies in the European Union can be founded under the conditions and in a manner regulated by the Regulation of the European Council as European companies called Socieatas Europaea. There are numerous differences between member states of the European Union regarding national legislation that must be harmonised in order to create a single European company law.
