This study focuses on the legal nature of the partnership relationship in the consortium and joint venture. In the court decisions, it is stated that these concepts create a partnership relationship and this is accepted that it is nothing other than the ordinary partnership institution regulated in the Article 620 ff of Turkish Code of Obligations. In the doctrine, some authors describe both concepts as sui generis and some as ordinary partnership. In this respect, the legal nature of the consortium and joint venture partnership models and the provisions to be applied accordingly should be determined. It should be noted that in order for a partnership relationship to be qualified as an ordinary partnership, it must have each of the minimum elements constituting an ordinary partnership. Within the scope of our study, whether the consortium and joint venture relationship carries the elements of ordinary partnership has been examined separately in terms of each element. After introducing the problematic in the introduction part of our study, the consortium and joint venture institutions are briefly introduced in the second part. In the third part, it has been examined whether the consortium and joint venture institutions have the minimum elements of ordinary partnership.
