This department is best known for its hands-on advice and participation in the transactions they are involved, because its partners (not only associates) get deep into the documents, details and document preparation. The corporate team works side by side with its tax and accounting team to find viable solutions to issues that otherwise could be deal breakers.

This year the firm decided to hire two lawyers to strength and increase its litigation and conflict resolution team. David Garcia who has 14 years of experience in administrative law and public procurement, having worked at the Attorney General Office and other government institutions, and Leyre Suarez recognised by Chambers and Partners as “Associate to watch in Dispute Resolutions”  based on her expertise in litigation and international arbitration.

Byron Robayo, who leads the IP team, has advised to the World Intellectual Property Organization (WIPO) and the Ecuadorian IP Office.

Their deep intellectual property knowledge, the speed, clarity, and frankness of communication are the most important tools that team wields.

Labour and employment and immigration 

This practice area has changed dramatically from previous years, still helping clients to reduce litigation exposure to the minimum. Still, when litigation cannot be avoided, our trial results are sound. Although no short-term results should be taken as a guarantee, this year our litigation team has been successful in over 90% of its trial cases.

Patricia Andrade, head of the team, offers their clients a complete consulting because of her deep knowledge, ability to negotiate and to explain the risk and solutions, that places us above other law firms.

Senior associate Xavier Montesdeoca is praised by the firm’s multinational clients for his immigration law services.
