What rights does owning someone's soul give me over that person? If I sold my soul to the devil, he would have me for an eternity in Hell after I die. However the devil is an eternal being, and human law only applies to mortals. I have to assume that ownership of a soul is revoked after the death of that soul, since human authority is transcended by a higher body of power. If I sold my soul to Mark Zuckerberg, what would he do with that power over my mortal life?

The answers to these questions will be codified into the new law, because they cannot be determined scientifically (yet.)

Due to it's non physical nature I don't think we could ever define "soul" scientifically, except perhaps as "the aspect of the human being which is not physical". Is it possible to own something non-physical? There is precedent, such as patenting an algorithm, or owning shares in a software company.
