Formation of Mitakshara coparcenary:- A single person cannot form a coparcenary. There should be at least two male members to constitute it. Like a hindu joint family, the presence of a seniormost male member is a must to start a coparcenary. A minimum of two members are required to start and to continue a coparcenary. Moreover, the relation of father and son is essential for starting a coparcenary. For example, a hindu male obtains a share at a time of partition from his father and then gets married. Till the son is born, he is the sole male in this family, but he alone will not form a coparcenary. On the birth of his son, a coparcenary comprising of him and his son, will come into existence. When this son gets married, and a son is born to him, the coparcenary will comprise the father F, his son S, and his grandson.
When a coparcenary is started, the seniormost male member, with his son, that is, lineal male descendant, till four generations (inclusive of him) of male line will form a coparcenary. If there is a lineal male descendant in the fifth generation, he will be the member of the joint family, but will not be a coparcenar as he is removed from the seniormost male member by more than four generations.
