The present work was a comparative exercise of legal guarantees regarding copyright between Colombian and Spanish legislation. The objective was to present a doctrinal tour of the regulations in Colombia and Spain in the matter of copyright to identify the legal guarantees that exist in both legislations, and later establish a comparative analysis between them. Colombia, as a developing country and Spain as a developed country, have made progress with respect to the regulations that regulate the different aspects derived from this kind of intellectual property. This approach was carried out through the comparative method, with a systematic analysis and a documentary screening through a qualitative non-experimental design. As a result, the doctrinal tour was carried out, the guarantees of both countries in terms of copyright were identified and from the analysis it was appreciated how Spain considers the protection of these rights with greater anticipation than Colombia, but in terms of guarantees they have quite a few Similarities in their legal systems, and in both legislations, copyright is separated into moral rights and economic rights, a situation that manages to give the importance that corresponds to moral rights that were overshadowed by economic rights. It should be noted that Colombia grants a greater range of protection to these rights, elevating them to fundamental rights, while Spain achieves the guarantees directly through the intellectual property law, both legislations consider access to the guardianship mechanism for their protection. Regarding the years of protection, in Colombia like Spain they are higher than the minimums established in the Berne Convention and the Andina decision 351 (1993), which allows us to infer that they grant a greater guarantee to the author and his heirs, in terms of property law.
