This paper will deal with the legal framework of citizen associations with a reference to sports associations. The association is in fact a free union of citizens, which by definition means that no one is forced to associate with each other, but they associate the protection of their prosperity or commitment to the protection of human rights and freedoms, as well as ecological, humanitarian, information, cultural, national, pronatality, professional, sporting, technical, medical, scientific or other beliefs and purposes, without the intention to obtain a profit. If they are to earn profits, the association must use that profit only to advance and improve the association itself as well as to the business of the association as written in the statute. It is regulated by the Associations Law, and the principles of the Association are also important, which provide a pictorial design what is the purpose of the association and how the association operates. In the paper we will clarify how the association registers, which of its bodies are, how the association operates, that is, which economic activities can be carried out by the association. Also in addition to the above mentioned, we will also touch on the closure of the association, whether to stop liquidation or fork and how we deal with the property in case of termination of the association. For the end of the work, we will mention sports associations, what are they, how one of the most important things emerges, and that is the transformation of a sports association into a sporting stockpile.
