About us

ITER Law is a boutique sector-focused law firm. Our client relationships are based on transparency, the efficiency of a cohesive team, and the experience of our partners, all with a shared goal: to provide innovative solutions.

Thanks to our experience, we have combined large firms’ capabilities and methodologies for comprehensive project management with the thoroughness, client-centric approach, attention to detail, and creativity of boutique firms. This approach lets us meet our clients’ demands for quality, expertise, proximity, and rapid results.

Miguel Huarte and Ignacio Careaga founded the firm in 2017 to meet the demand for specialised consulting in specific sectors (the Anglo-American philosophy of Sector Focus), specifically in the following sectors: Infrastructure; Energy; Construction and Engineering; Real Estate, and Property Development.

As head of the Management area, his business vision and professional experience of more than thirty years at the helm of important multinationals has brought enormous added value to the organisation of the firm.
