International disputes are always dealt with under the provisions of international law. Kashmir is an international issue, which needs to be resolved under the ambit of international law. The Fourth Geneva Convention-1949 provides a strong basis for addressing the legal basis of the Jammu and Kashmir dispute. As an international dispute, Kashmiri warrants the application of international law for its logical resolution. Unfortunately, notwithstanding UNSC resolutions, India unilaterally and illegally changed the status of occupied Jammu and Kashmir from a state to the union territories through Jammu and Kashmir Reorganization Act-2019. Later through a number of amendments, Adaptation of State Laws in April 2020, India brought changes in dozens of local state laws, meant to bring changes in the existing demography of the state. This research focuses on the changes India has engineered in the new domicile laws of Indian Illegally Occupied Jammu and Kashmir (IIOJK) to change the demography of the state. The paper also focuses on the legal position of these changes in IIOJK from the perspective of International Law and the Fourth Geneva Convention.
