The Constitution may be defined as the country's constitutional rule which serves as the foundation for the development and enforcement of all other legislation. We should both agree that the Constitution is the mother of all rules that derive their legitimacy from it. It further establishes the framework, jurisdiction, and limitations for all legislation enacted by a country's legislative body. It's one thing to write a constitution, yet another to change it. Amendments are made in response to changed circumstances, the will of the people, or the vote of the people. All three of these nations are democratic in the world: India, the United States of America, and the United Kingdom. The researcher aims to understand the problems faced in amending any part of the constitution. The whole study of the research paper is based on the Qualitative research method and various comparisons are done by the authors of the paper to understand the current situation. Furthermore, the critical analysis by various other authors is also kept in notice in order to base the research on already existing facts. The project ends with a conclusion by critically analyzing the amendment procedure in all three countries and providing the best amendment procedure amongst them in relation to the needs of the changing society.
