In order to avoid future succession issues, the Emperor made the marriage conditional on Elisabeth's renouncing her right to succession, although he allowed her to keep her personal title and style, as well as providing her with a generous dowry. While his family was officially listed in the Habsburg list of families which were allowed to make an equal marriage ("Ebenbürtigkeit") with an Imperial family, they still regarded Otto's Mediatized House and the marriage as a mésalliance and wanted the marriage to be treated as morganatic. As it was a case of the Emperor's favorite granddaughter and Otto's family was legally considered equal for dynastic purposes, as were marriages with all other mediatized Princely families, the marriage was officially treated as equal and his family would have grounds for pressing Elisabeth to become empress should the succession become interrupted again.
