Natalia Mori

Baker & McKenzie LLP


Natalia has a solid background in administrative law, public-private partnerships and domestic and international arbitration.

Practice Focus

Her practice is focused on advising private companies in the execution of public infrastructure projects through different types of investment contracts with public entities of the three levels of government. Natalia advises concessionaires and investors integrally, from their participation in the corresponding bidding process for the award of the respective concession agreement and its contractual execution, to the solution of disputes that may arise between the investor and the state entity through national or international, commercial and investment arbitration.

Natalia has been part of the team that has successfully represented concessionary companies in more than six international commercial and investment arbitrations under the UNCITRAL, ICSID, CAIP arbitration rules, among others. She has led the defense on allegations of corruption in the framework of international arbitration of important municipal concessions in Lima.
