The recent Lithuanian court practice shows discrepancies in cases dealing with partitioning of common partial divided property. Moreover, no doctrinal research has been concluded on the limits and conditions of the co-owners‘ right to demand that his share should be partitioned from the common partial ownership in Lithuania. Taking into account that proper implementation of co-ownership rights is based on common agreement of co-owners, when no agreement is reached between co-owners regarding the fact and the mode of partitioning, a question (...) arises on what conditions and to what extent the co-owner is free to implement his right to demand partitioning of his share from the common partial ownership. The research on historical developments of the partition law in different European countries shows that the co-owner’s right to partition is based on the idea of pluralistic conception of the modern property law objects. The authors of this article argue that this conception allows the co-owner to enjoy the right to dispose of his share in the common ownership as a separate object of civil turnover at his own volition and without the other co-owner’s consent. However, the right to partition is not absolute and is limited by the rights of the other co-owner to his share of the same property, so the right to partition may be implemented only following the proportionality and interest balance between the co-owners.
