Argentina’s UIF Alleges 88% of Kirchner Family Real Estate Company’s Revenue Was Linked to Money Laundering

Argentina’s Financial Information Unit (Unidad de Información Financiera – UIF) has alleged that 88% of the revenue generated by Los Sauces S.A., a real estate and hotel company linked to former President Cristina Fernández de Kirchner and her family, originated from transactions used to give an appearance of legitimacy to funds allegedly obtained through corruption. The allegations were presented during the ongoing oral trial concerning the Hotesur and Los Sauces cases, which examine suspected money laundering and corruption involving the former presidential family and several business groups.

According to the UIF’s submission, Los Sauces received approximately 25.97 million Argentine pesos between 2009 and 2016 from companies associated with businessman Lázaro Báez and the Indalo business group, controlled by Cristóbal López and Fabián de Sousa. These payments represented 88% of the company’s total invoiced revenue during the period. The UIF alleges that the transactions formed part of a wider arrangement through which funds derived from public contracts and other alleged benefits granted to private businesses were channelled back to the Kirchner family through property rentals and related commercial arrangements.

The case centres on allegations that public works contracts and other government benefits were awarded to companies connected to the business groups involved, after which part of the resulting funds was transferred to Los Sauces through rental payments for properties and hotel facilities owned by the family. According to the prosecution's theory, these arrangements allowed funds of allegedly illicit origin to be presented as legitimate income generated through ordinary commercial activity.

The UIF identified payments totalling approximately 6.85 million pesos from companies associated with Báez, 18.55 million pesos from the Indalo group and a further 561,665 pesos from hotel management company Idea S.A. The companies identified in the investigation include Austral Construcciones, Kank y Costilla, Loscalzo y Del Curto, Valle Mitre, Álcalis de la Patagonia and Inversora M&S. The concentration of revenue among these related business groups is a central element of the allegation that Los Sauces was used as a vehicle for recycling funds.

Los Sauces was incorporated on 7 November 2006 by Cristina Fernández de Kirchner, her husband and former president Néstor Kirchner, and their son Máximo Kirchner. Its corporate purpose included real estate, hotel and tourism activities. The UIF's account traces the company's development through a series of property acquisitions, capital contributions, rental arrangements and transactions involving businesses that had received public contracts or other government-related benefits.

Among the transactions examined was the acquisition of a 426-square-metre apartment in the Madero Center complex in Buenos Aires, which was subsequently rented to companies associated with the Indalo group. A duplex in the same complex, together with five parking spaces, was also acquired and leased to Inversora M&S. The authorities allege that these properties formed part of the mechanism through which payments from the business groups were converted into rental income received by the family company.

Other transactions involved properties in Río Gallegos and El Calafate. In Río Gallegos, a plot of land transferred to Los Sauces was developed into four apartments by Loscalzo y Del Curto, a construction company associated with Báez. The apartments were subsequently rented to Kank y Costilla, another company linked to the same business group. The UIF also questioned the acquisition of land in El Calafate for 136,149 pesos, despite an official valuation of approximately 445,000 pesos at the time.

The purchase of Hotel La Aldea del Chaltén was also included in the allegations. Los Sauces reportedly acquired the hotel for 200,000 pesos, while the UIF cited an estimated market value of approximately 2.89 million pesos. The property was subsequently rented to companies including Valle Mitre and Idea. Investigators also examined a transaction involving a plot of land in Río Gallegos that was allegedly transferred from Austral Construcciones to Los Sauces under the appearance of a sale for US$97,000, which the UIF maintains was a simulated transaction.

The allegations attribute distinct roles to Cristina Fernández de Kirchner and her son Máximo. The UIF identifies the former president as the alleged head of a criminal organisation said to have operated between May 2003 and December 2016. It alleges that she planned, coordinated and directed the suspected money-laundering arrangement through Los Sauces between January 2009 and March 2016. The submission further maintains that she approved the company's annual accounts, authorised property acquisitions, appointed members of its board and withdrew funds for personal benefit.

Máximo Kirchner, currently a national legislator, is alleged to have acted as the organiser of the arrangement and the principal operator of the family's private businesses. He served as president of the board of Los Sauces and was involved in property purchases, rental contracts and financial transactions. The UIF alleges that he signed relevant agreements, deposited cheques issued by the business groups into the company's bank accounts and participated in transactions that investigators consider simulated or commercially unjustified.

Florencia Kirchner, the former president's daughter, is not among the defendants in the current proceedings. She inherited shares in Los Sauces following her father's death in 2010, but was subsequently dismissed from the case by the Federal Criminal Cassation Court. That decision became final and she is therefore excluded from the trial.

The proceedings concerning Los Sauces have been combined with the separate Hotesur case, which concerns another company associated with the Kirchner family and the operation of the Alto Calafate hotel. The consolidated trial is being heard by Federal Oral Criminal Court No. 5. The proceedings began in October 2026, following earlier procedural decisions that allowed the cases to proceed jointly. The court is currently hearing the prosecution's allegations and the arguments presented by the UIF, which is participating as a private prosecuting party.

The criminal allegations must be distinguished from established judicial findings. The UIF's submission sets out its interpretation of the evidence and the alleged roles of the defendants, but the ongoing trial must determine criminal responsibility. The fact that the transactions and payments have been identified in the proceedings does not, by itself, establish that the funds were criminal proceeds or that the defendants committed money laundering.

The case highlights the potential use of real estate and hospitality businesses to disguise the origin of funds through transactions that appear to generate legitimate commercial revenue. Rental agreements, property acquisitions and payments between related business groups can provide a mechanism for transferring value while creating documentation that may make the underlying movement of funds appear consistent with ordinary business activity.

For AML professionals, the allegations demonstrate the importance of examining the economic substance of property transactions and the relationships between counterparties, rather than relying exclusively on invoices, contracts or the stated purpose of payments. A concentration of revenue among a small number of commercially connected customers, particularly where those customers have significant public-sector contracts, may warrant closer scrutiny. Other relevant indicators include rental payments that appear disproportionate to market conditions, transactions involving undervalued property, unexplained transfers between related entities and business arrangements that lack a clear commercial rationale.

The proceedings will also be relevant to the assessment of politically exposed person (PEP) risk. Business relationships involving individuals holding or previously holding prominent public functions require appropriate risk assessment, including consideration of the source of funds and wealth, the nature of counterparties and potential links to public procurement or government decisions. The case illustrates how property-owning companies and apparently routine rental arrangements can become central to investigations into alleged corruption and the movement of proceeds.

As the Hotesur and Los Sauces trial continues, the court will examine the evidence supporting the alleged connections between public contracts, private business groups and the Kirchner family's real estate and hotel activities. The outcome will determine whether the transactions constituted legitimate commercial arrangements or formed part of the criminal scheme alleged by the authorities.
