INDISPENSABLE PARTIES:

   where the EJECTMENT suit IS brought by a co-owner, without repudiating the co-ownership, then the suit is presumed to be filed for the benefit of the other co-owners and may proceed without impleading the other co-owners.  the other co-ownerS are not considered as indispensable parties to the resolution of the case. On the other hand, where the co-owner repudiates the co-ownership by claiming sole ownership of the property or where the suit is brought against a co-owner, his co-owners are indispensable parties and must be impleaded as party-defendants, as the suit affects the rights and interests of these other co-owners.
