Moral rights are a set of rights granted to creators of original works—such as designers, writers, and artists—that protect their personal and reputational connection to their work. In many jurisdictions, these rights include the right to be identified as the creator (attribution) and the right to object to derogatory treatment of the work (integrity).
A moral rights waiver is a contract clause where the creator (or agency) agrees to give up some or all of these rights, often so the client can freely modify, adapt, or use the work without needing further permission or crediting the original creator.
