The access on the part of one of the members of the couple to the data of the other member, contained in shared documents, is a cession (article 11 of the LOPD), so that, to lack of the express consent of the headline, it would be necessary to eliminate of this document the data that are a titularity from the other member of the couple, without harm of determinate accesses fitted out. The data related to the pre-embryos can be considered titularity information of the two members of the couple, so that they both would have the right from access to the documents that contain this information.
