- The Economic Interest Grouping (Agrupación de Interés Económico) is a legal entity with commercial character that helps its members develop or improve their economic activity. It has no profit motive of its own, and its purpose must be an activity auxiliary to that of its members.
- Only individuals or companies carrying on business, farming or craft activities, nonprofit research entities, and liberal professionals can form one. Members are personally and jointly liable for its debts, though their liability is secondary to that of the Grouping.
- The Grouping must be registered in the Commercial Registry (Registro Mercantil), and its name must include the words «Agrupación de Interés Económico» or the initials A. I. E. The founding deed must state, among other things, the members, capital, name, purpose, and a domicile in Spain.
- Decisions require unanimity unless the deed allows other quorums; some key matters always require unanimity. The Grouping is managed by one or more administrators, who represent it and must act with the diligence of a diligent businessperson.
- The Grouping is dissolved for reasons such as unanimous agreement, expiry of its term, bankruptcy, or a single remaining member. It can transform into another type of company or merge, and profits and losses are shared among members as set out in the deed or equally.
