<p>Legal battles in the contemporary era increasingly hinge on language. This has led to emergence of forensic linguistics at the convergence of law and linguistics by transforming speech and written text into powerful weapons in the arsenal of justice. Forensic linguistics is a burgeoning branch of forensic science which applies linguistic principles and techniques to analyze data and assist investigations and adjudication. This paper highlights the growing relevance of forensic linguistics in criminal justice systems by framing the study around three core applications, which are false confessions, suicide notes, and threat letters. Beyond showcasing its utility, the research critically engages with the limitations and evidentiary challenges of forensic linguistics by drawing on foundational forensic principles, judicial precedents, emerging trends and relevant statistical data. To address institutional blind spots in the forensic infrastructure of India, the paper further scrutinizes international best practices from the United States of America, Germany and the United Kingdom to ultimately propose a legislative framework for effective integration of forensic linguistics within the Indian legal system for advancement of justice.</p>
