What is the articles of association?
The articles of association are a public and mandatory document that formalizes the creation of a company and establishes its legal structure. This document must be signed before a notary and subsequently registered in the Commercial Registry, which grants the company legal personality and allows it to operate legally.
The deed includes essential aspects such as the identity of the founding partners, the share capital, the purpose of the company and the rules of administration. In short, it is the basis on which the company will be governed, guaranteeing that its operation complies with current legislation.
