The ‘tenacious and strong‘ team is highly active in the arena of litigation, with recent cases involving state aid, abuse of dominant position and unfair competition rules, in addition to boasting a sizeable compliance practice. The firm also advises on merger control cases, frequently acting as local counsel to international companies with operations in Ecuador on obtaining authorisation from the Ecuadorian Competition Authority. The firm is led by David Sperber and Gilberto Gutiérrez, both of whom are highly experienced across the full range of contentious and non-contentious antitrust work.

Practice head(s):

David Sperber; Gilberto Gutierrez


‘This is a new and very specialised area of law in Ecuador, which means there are few experts. At other firms, these matters would be handled by lawyers with much less experience.’

‘We receive a personalised service from the lawyer handling our matter, rather than it being delegated to more junior team members.’

‘The team pay attention to the details. They make a great effort to fully understand all the relevant issues and are available to the client 24/7. They go the extra mile.’

‘I admire the fact that all the lawyers at this firm are tenacious, strong and not easily intimidated by opposing counsel. They have been a tremendous support to me.’
