What is a provision trace in legal document analysis?

A provision trace in legal document analysis tracks a specific clause through every contract version to find the current controlling language. It compares the base agreement and all amendments chronologically to show how the provision evolved and what the final binding terms are.

Can I upload multiple contract amendments for comparison at once?

Does contract change detection require a specific file format?
