A treaty is a formal, legally binding written agreement between actors in international law. It is usually made by and between sovereign states, but can include international organizations, individuals, business entities, and other legal persons. A treaty may also be known as an international agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms. However, only documents that are legally binding on the parties are considered treaties under international law. Treaties vary on the basis of obligations, precision, and delegation.

The treaty provides authors, musicians, poets, painters, and other creators with the means to control how their works are used, by whom, and on what terms. In some jurisdictions these type of rights are being referred to as copyright.
