Since the entry into force of Law 10/90 on sport, Sports Limited Companies have been shown in our legal system to be sporting-mercantile entities that have not fully met the objectives intended by the legislator. The aim of this study is to find out how this figure has been treated in the comparative law of our immediate environment, but also in Latin America and the United States. After comparing Spanish law with the rest of the systems analysed in this area, some reflections are extracted to stimulate the legal debate, which may help the legislator to establish minimum standards in the new sports legislation that is being drafted. All of this, with the aim of complying with the current reality of commercialised professional sport, without losing sight of the non-economic dimension of this sphere of sport (links between the city and the sporting entity, grassroots sport in professional sporting entities, etc.).
