A Swiss association ("Verein" in German, "association" in French, "associazione" in Italian) is a legal structure in Swiss law, defined in the civil code (Part one, title two, chapter two). It is similar to the Anglo-American voluntary association. Unlike in Germany, a Swiss association does not need to be registered in order to have a separate legal personality. It must be registered if it "conducts a commercial operation". An association can serve as a non-profit organization (NPO) or non-governmental organization (NGO) and this form is used by several Swiss sections of international NGOs such as Amnesty International, and the World Wildlife Fund, by business firms (see below) or by international organizations such as the Fédération Internationale de Football Association (FIFA). The form can also be used by political parties and alliances, such as trade unions.
