An amendment is a formal change or addition made to a document, such as a constitution, law, or contract. It is typically made in order to clarify, modify, or update the original document. Amendments are often necessary when circumstances change or new information becomes available that was not previously considered. They provide a mechanism for ensuring that the document remains relevant and effective over time. Amendments can be proposed and ratified through various processes, depending on the specific document and governing body involved. Once an amendment is successfully adopted, it becomes an integral part of the original document and carries the same legal weight and authority.
