Warranty of Authorship(Copyright) Law and Legal Definition

Warranty of authorship refers to an author’s contractual warranty. Having a warranty implies that the work of an author is original work by that author. Through a warranty of authorship, an author guarantees to a publisher that his/her work is original and that s/he is the sole author. An author also guarantees that s/he has the full power to make the agreement. A warranty of authorship provides for an indemnification clause whereby an author indemnifies a publisher against any losses and other expenses. Expenses also include reasonable attorney's fees after final judgment of any claim or action against any of all of these warranties.[Rohmer v. Commissioner, 21 T.C. 1099 (T.C. 1954)].
