A co-publishing agreement means that while the music publisher has ownership in the copyright and administers its exploitation, another publisher (possibly a songwriter’s own company) controls the other piece of the publisher’s share of ownership. This type of agreement often happens when established songwriters who have a lot of power within the industry establish their own publishing entity and enter in an agreement with another publisher.
