As explained in the previous chapter, if one is prohibited by a vow from deriving benefit from another, even the most minimal benefit is forbidden. Therefore, the one who takes the vow will be enjoined not only from deriving benefit from the other’s property, but also from deriving benefit from shared property, lest he benefit from the other’s share. This chapter deals primarily with issues of deriving benefit from property shared by multiple owners. This occurs primarily through partnerships or from benefit gained through communal or public property, although shared ownership can result from a number of other situations. In the case of public property, one must determine each party’s degree of ownership, since their share may be so small as to be negligible, thereby rendering the property ownerless. The chapter also discusses effective and ineffective ways of circumventing vows in order to indirectly benefit the prohibited individual. While some methods may be considered legitimate means of offering indirect benefit, loopholes that are solely legal fictions are rendered invalid. Finally, this chapter explores the possibility of rendering entities forbidden to oneself or to another that have not yet come into or have already left one’s possession.
