Their proven performance in handling high-value transactions for multinational clients demonstrates that narrow focus does not equate to constrained scope.Full-service firms: ABNR, Assegaf Hamzah, and others for comprehensive supportOn the other hand, full-service powerhouses like ABNR and Assegaf Hamzah & Partners offer a holistic suite of legal services.
