The advantage of obtaining official recognition of authorship for a non-published artwork is that you register the artwork and your ownership of it as well as fixing the date of the artwork creation. The registration is done with the Russian Authors Society.
Why register copyright
When you face a conflict related to illegal use of an artwork by third parties or you end up disputing your authorship in court it is much easier to prove your authorship if your copyright was officially registered. The court will examine the authorship certificate as evidence.
You may dispute somebody’s authorship by documents proving that the artwork in question existed earlier than the date of registration (deposit) of the disputed artwork. We recommend that the copyright be registered and the artwork be deposited with the Russian Authors Society (RAS) as early as possible.
