Šiame darbe atskleidžiama reikalavimo perleidimo instituto esmė, jo skirtumai nuo panašių institutų, reikalavimo perleidimo sutarties pagrindiniai ypatumai. Darbe tai pat analizuojama Lietuvos ir užsienio šalių teismų praktika, moksliniai straipsniai, daug dėmesio skiriama reikalavimo perleidimo sutarties šalių bei skolininko teisinei padėčiai apibūdinti esant tiek vienašalei, tiek dvišalei pirminei prievolei. Analizuojant reikalavimo perleidimo galimybę vienašalėje prievolėje pagrindinis norminis tyrimo šaltinis – 2001-07-01 d. įsigaliojęs Lietuvos Respublikos civilinis kodeksas. Taip pat analizuojama Lietuvos teismų praktika, tačiau ji nėra gausi. Siekiant atskleisti galimyb����� sudaryti cesijos sutartį ir perleisti iš dvišalės sutarties kylančias ne tik teises, bet ir pareigas, analizuojami Latvijos, Vokietijos, Jungtinių Amerikos Valstijų teisės aktai taip pat UNIDROIT tarptautinių komercinių sutarčių principai. Pažymėtina, jog plačiausiai reikalavimo perleidimą dvišalėje sutartyje analizavo JAV teisės mokslininkai, taip pat šiuo klausimu gausi yra ir Jungtinių Amerikos Valstijų teismų praktika, kuria buvo remtasi ieškant atsakymų į iškeltus klausimus. / This master work contains analysis of a status of all provisions of an original contract, also of a legal position of an assignor, an assignee and a debtor when an assignment contract is signed. An assignment of claim in Lithuanian legal system is defined in Chapter VI Book six of the Civil Code of Lithuania. According to the Civil Code a creditor may without the consent of the debtor assign to another person all or a part of the claim provided that the transfer does not contradict to laws or the contract, or the claim is not related with the person of the creditor. While analysing an assignment of claim in foreign countries, the great attention is paid to the assignability of bilateral contracts.

The introduction of a regulatory framework in the area of collective management of rights in Nigeria must have been intended to strengthen the creative industry. Unfortunately, it has thrown this industry and in particular the music and film industries into a battle of a regulated against a non-regulated collective administration sector for upward of twenty (20) years. My choice of research on this topic could be attributed to the interest I developed while administering the collective administration desk at the Nigerian Copyright Commission. Serving on that desk afforded the opportunity to see the frustration of right owners who were being deprived the fruit of their labor, as the societies meant to collect and distribute royalties on their behalf were enmeshed in litigations and in the process, rarely paid any royalties to authors. Within this context, this research seeks to explore whether there is any merit in the continued existence of the current regulatory framework for collective management in Nigeria, and what the best operational framework for collective administration in Nigeria would be. A methodological approach entailing literature review of books, articles, journals, legislation, cases, reports of committees and interviews with experts was adopted, with critical analysis carried out on particularly the Nigerian Copyright Act, the Nigerian Copyright (collective management organisation) regulation, the South African Copyright Act, the South African Performers’ Protection Act, the South African Collecting Societies Regulation, as well as judicial decisions challenging certain provisions in the Nigerian legislation. It is hoped that this research will spur a desire for the need for supervisory and regulatory agencies of government to seek the national interest above all others in taking and making decisions that affect the collective administration of copyright and related rights. / Mercantile law / LL.M.
