Co-ownership of an original work is recognized where the work has been produced by the collaboration of 2 or more authors and in which the contribution of each author is not separate from the contribution of the other author(s). Subject to a written agreement to the contrary, all co-owners of copyright must consent to the licensing of the copyright by any other joint owner.
An owner of a copyright may grant a license over some or all of the owner's rights. Statutory licensing schemes operate to allow certain copyrights to be used without the permission of the copyright owner, but this is conditional on the payment of equitable remuneration for that use, or a fair dealing exception applies. An owner may also assign their copyright or future copyright to another person.
