As one of the main pillars of private law, commercial law in its entirety regulates relationships arising from commercial activity. It applies to merchants, businesses, and transactions related to commerce.

From the outset, it distinguishes the differences between a merchant and a private individual and the advantages of the commercial profession.

It includes, first, company law, which governs the formation, operation, and dissolution of each type of company, whether a partnership (civil partnership, general partnership, limited partnership) or a capital company (S.A., Private Company, Ltd.).

It also covers bankruptcy law, which today offers a second chance to vulnerable debtors, allowing them to settle their debts and reintegrate into economic life.

Negotiable instruments law also plays an important role, such as bills of exchange and checks, which, as financial instruments, enable the continuous and uninterrupted flow of money, adapted to the needs and pace of commerce.

In addition, there is competition law, which regulates permissible conduct between businesses, and intellectual property law, which ensures the legal protection of patents and inventions.
