A subjective copyright is composed of a stream of property and personal authorizations. Therefore, legal theory was in a dilemma whether there are two separate copyrights (property and ethical rights) or a singular copyright. Although contemporary legislations embrace the monistic doctrine on legal nature of copyright, certain legislative solutions must deviate from their consistent application. Primarily, the dualism in copyright authorizations applies to their duration and transferability. Namely property rights are effective over 50 years upon the author’s death, whereas effectiveness of personal rights is not limited in time. Given that a copyright outlives the author, the lawmaker took into consideration the general principles of non-transferability of personal rights and transferability of property rights when regulating the succession of copyrights, whereby he introduced a dual legal regime. Therefore, property rights of an author may be transferred fully to his heirs under the general rules of succession contained in the regulations of the republics. Personal authorizations are not transferable to successors. However, the heirs are entitled to exercise the rights equally to copyright organizations. Nevertheless, the essence of such authorizations is transformed by the author’s death, since exercising of the rights then comes down to protection of ethical interests of the deceased author. However, all means of protection provided by the criminal and civil law are available to the abovementioned persons, except for compensation of immaterial damages.
