The Principality of Asturias has various forms and instruments that allow, from a legal perspective, the initiation of economic activities within its territory and from it to operate in Spain and the European Union (as a first step). All these forms are included in the common Spanish legislation without the coexistence of others, so the legal entities that will be discussed below are applicable throughout the Spanish territory.

There are several ways to establish a presence (physically or digitally) to conduct business in Asturias, both as an individual and through associative contracts, business institutions, or by establishing corporate entities. The practical approach revolves around the consideration of the temporality of the intended business, categorizing: (i) temporary establishments – generally a means of collaboration with other entrepreneurs – such as unincorporated joint ventures, consortium agreements, Temporary Business Alliances (UTE), etc., and (ii) branches, business entities, and the figure of individual entrepreneurs as Limited Liability Entrepreneurs (ERL)

This section also addresses the opening of branches, the acquisition of real estate or asset deals, business acquisitions (share deals), participation in venture capital investment funds, and other commercial agreements such as distribution, agency, commission, and franchise contracts.

For practical reasons, this guide focuses on the two main corporate forms in Spain, S.L. (Limited Liability Company) and S.A. (Public Limited Company), without excluding other modalities, which will be mentioned with less detail.
