In September 2017, EMB demerged into two legal successors: Universal Music Publishing Editio Musica Budapest Zeneműkiadó Kft (UMPEMB) and Editio Musica Budapest Zeneműkiadó Kft (EMBZ).

The copyrights for 20th century music as well as contemporary works remained under the purview of Universal Music Publishing Editio Musica Budapest Zeneműkiadó Kft. UMPEMB also continues to oversee the Hire Library and Copyright departments of the original EMB.

The publishing rights of the remaining thousands of pedagogical publications (as well as those of the scholarly Liszt and Bartók Complete Critical Editions) were transferred to the newly reestablished Editio Musica Budapest Zeneműkiadó Kft. EMBZ produces and distributes not only its own scores, but also those of UMPEMB. It also continues to distribute the scores of other foreign publishers within Hungary.
