Trilegal is home to a well-experienced antitrust and competition practice with expertise in both contentious and non-contentious matters, including merger control, enforcement cases, audits, and compliance. The team is relied upon by a notable and growing client roster consisting of automotive, pharma, and e-commerce businesses seeking assistance with high-value, high-profile, multijurisdictional transaction filings, investigations into abuse of dominance and cartel conduct, and dawn raids. Aparna Mehra — who joined the team from Shardul Amarchand Mangaldas & Co in January 2025 — and Gauri Chhabra co-head the department alongside Gautam Chawla and Rudresh Singh, all of whom bring a wealth of prowess to the team. Mehra specialises in merger control and remedies, while Chhabra concentrates on enforcement — including cartel and abuse of dominance cases — and transaction filings. Both Chawla and Singh are noted for their aptitude for handling contentious mandates relating to restrictive practices, market dominance, and cartel investigations before the CCI, the NCLAT, and the Supreme Court. Divye Sharma is another name to note, and Nisha Kaur Uberoi left the firm in August 2024.

Testimonials

‘The team is engaging, prompt and solution-oriented, which is a godsend for clients that work in a heavily regulated space.’
‘Both Ankush and Gautam (partner) are readily available for assisting on ad-hoc requests and some unique propositions, which crop up from time to time. Their advice understands the business' needs and marries it with the requirement to comply with applicable law.’
‘Firm delivers strong regulatory counsel, makes up-to-date antitrust implementations.’
‘We have worked with Krithika Ramesh for many years in relation to our competition litigation in India. Krithika is an excellent lawyer who handled a fact-heavy file with commendable maturity and thoroughness. Krithika's drafting and legal analysis is excellent, and her output is timely. She supported her partners very effectively, while being a fantastic mentor to the younger associates on the file. We found her to be always prepared with all the facts and arguments – which was of great help while briefing senior counsel on the matter.’
‘They don’t just provide legal advice — they understand the on-ground realities and constraints we face, and they offer pragmatic, solution-oriented counsel. Their responsiveness, strategic foresight, and industry knowledge have consistently made them a trusted partner, not just a legal adviser.'
