The original scheme of commercial law or Lex mercatoria as a milestone in the development of this branch of law represents the need for uniform rules in the area of economic entities. This area of law has since evolved further and now includes legal norms and institutes, which relate to the economic system as a whole. The main focus of this area of law is drawn to the presence and organisation of economic entities in the market, as well as concluding of commercial transactions. The concept of commercial law is extremely broad, and in this context, the scope of this branch covers the legal aspects of companies, which includes founding, organisation and functioning of personal and capital companies. Helping a company make the right choice can contribute to better and more efficient business. Legal services within this context relate to the preparation of company founding acts, the conclusion of various contracts, representation of stakeholders and shareholders at general meetings and providing legal advice to the management of companies.
