Oscar de Santiago, a Garrigues partner, is the co-head for the Cataluña, Aragón and Balearic Islands area and the head of the Legal Department in that area.

He has a wealth of experience in the area of real estate law, both on the more traditional side, taking in sale and purchase, construction and lease transactions, and in more finance-related aspects, in the form of the financing and refinancing of real estate development projects and the taking up of stakes in property companies by acquiring equity and/or under mezzanine arrangements. In recent years, he has worked in close collaboration with some of Spain’s leading financial institutions through the entire process for the award of assets, divestments, portfolio reorganizations or the disposal of portfolios under an array of methods (disposal of asset packages, NPLs, the liquidation of real estate companies owned by financial institutions, swaps, commissioned development agreements, management agreements, etc.), having advised, over the last 4 years, on deals with an overall value of 7,000 assets and €8,000 million, taking in assets and/or associated debt.

He has advised domestic and international companies on the acquisition, management and disposal of real estate assets. In particular, noteworthy recent deals include transactions involving asset portfolios and packages (direct or asset-based acquisitions of office buildings, shopping malls and logistics parks and the disposal/acquisition of major packages of branches under sale and leaseback regimes). On the financing front, he has participated in the arrangement and modification of mortgage loans, syndicated loans and, in particular, processes to refinance some of the country’s largest real estate companies. Elsewhere, recent transactions also include advice on real estate and regulatory aspects to both financial institutions and investors on the creation and start-up of vehicles for the transfer and management of major asset and loan portfolios, as well as advising international investors on the taking up of a stake in or debt acquisitions at real estate companies of financial institutions.

He currently coordinates and is a lecturer for the real estate module of Esade’s Master’s of Specialization in International Business Law, and he was an associate lecturer at Universitat Pompeu Fabra from the academic year 1996/97 to the academic year 2013/2014 in civil and contractual law “practicum” course.
