Testimonials

Collated independently by Legal 500 research team.

  • ‘Comprehensiveness. There is no loophole or doubt in this (tax) area that has not been reviewed by the A&O Shearman team. Availability. Security and confidence. You know that the transaction will be successful, and you will not encounter any surprises or inconveniences.’

  • ‘Once a topic is submitted to their examination, no angle is left unexamined or question left unanswered. They transmit security and confidence. Outstanding also seems to me to be a short adjective for Ishtar Sancho and Juan José Sánchez. Extreme professionalism.’
