It has been stated in the Constitution of India that freedom of religion is one of the fundamental rights of the people. According to secularism, every citizen of the country has a fundamental right to practice his or her religion. Though practicing a particular religion or changing to other religion is a right but it is matter of great concern that people are converting to other religion due to personal interest on other religion or to get some favour or facilities. So, religious conversion has become the subject of passionate debate in contemporary India. From the early 20th century onwards, it has surfaced again and again in the political realm, in the media and in the courts. During the last few decades the dispute has attained a new climax in the plethora of newspapers, journals, and books whose pages have been devoted to the question of conversion. The most debatable question is if a person exercises the right to conversion and changes his religion then what conflict of law situations it can create under the matrimonial law? In the present paper the author has made an attempt to focus on how the people are lured to convert to other religion especially in the District of Kandhamal of Odisha and the author has tried to justify with the help of a case study. In addition to this, the author has made an attempt to define the concept of religion, religious conversion and its impact. The author has also concentrated on the religious conversion vis-a-vis conflict of matrimonial laws in the light of decided cases. At last, suggestions are made for preventing anti-conversion and to enact a comprehensive law in this regard in India
