Investigation Against Sergio Yáber Reveals Alleged Hidden Payments to Angela Vivanco Involving Domestic Workers and a Porsche

A summary investigation has concluded that Sergio Yáber, the Conservator of Real Estate (CBR) in Puente Alto, operated a sophisticated influence-peddling scheme aimed at personal gain, manipulating judicial and notarial appointments, and channeling under-the-table payments to officials, including former Supreme Court Minister Angela Vivanco, through hiring her domestic worker and selling a Porsche Cayenne at below market value.

The document detailing the charges, which spans 145 pages, was prepared by judicial prosecutor Carla Troncoso and concluded on December 31, 2025. The digital outlet Reportea has accessed its contents, which depict a systematic abuse of public office for private purpose, influence peddling, and a potential money laundering network.

This investigation, conducted by the Court of Appeals in San Miguel, coincides with Yáber’s formalization in the so-called «Belarus scheme,» where the Public Ministry accuses him of engaging in laundering maneuvers to conceal bribes paid to Vivanco by attorneys Mario Vargas and Eduardo Lagos. His formal charges in this case are scheduled for mid-January.

Network of Unjustified Payments

According to the cited outlet, prosecutor Troncoso accuses Yáber of a series of legally unjustified payments benefiting former Santiago Court Minister Antonio Ulloa, totaling more than $74,000,000 in regular transfers. Additionally, payments were made to former minister Angela Vivanco through hiring her domestic worker, the sale of a luxury vehicle, and monthly payments to her partner, Gonzalo Migueles.

The list also includes relatives of two ministers from the San Miguel Court who supported his nomination to the CBR of Puente Alto in 2018, as well as a network of notaries connected to Yáber, Claudio Barrena and Rodrigo Ortúzar, who are suspected of being involved in large money transfers.

«All the evidence gathered supports the conclusion that the accused has misused funds from his public office to create an influence trafficking network, thereby diverting the purpose of Public Function and its discredit,» the prosecutor stated in the document.

The «Under-the-Table Payment» to Vivanco via Domestic Worker

One of the most significant findings of the investigation is the hiring by the CBR of Puente Alto of Leidy Moreno, who concurrently worked as a domestic employee in the home of the couple Angela Vivanco and Gonzalo Migueles.

Moreno reportedly received payments from February 13, 2020, until February 2, 2023, with salaries ranging between $300,000 and $400,000 monthly, according to banking records of Yáber reviewed by Reportea.

«Workers acknowledge that Moreno also worked in the Migueles Vivanco household, which, taking into account her full-time employment contract and the salary she received, allows me to conclude that this is a disguised form of payment to Vivanco,» the prosecutor stated.

The scheme becomes more complex upon confirming that after her employment with Yáber ended, Moreno was immediately hired by notary Fernando Martel, retaining her job tenure unlawfully and receiving a severance payment of $2,000,000 from the CBR.

«This woman not only advanced in her remuneration for the role while apparently not working in it but was also transferred to Martel with a severance package under a new contract that respected her tenure in the conservator’s role: Moreno’s severance was signed on a Friday, and her subsequent contract with Martel was on the following Monday. The connection and continuity in this concealed payment is evident, under the formula of an employee who surely did not fully receive the $2,000,000 from her settlement, as her tenure is recognized in the following contract with another employer, which is not only creative but illegal,» the prosecutor asserted.

She also pointed out that according to the records, Moreno is a migrant worker without permanent residency in Chile, placing her in a vulnerable situation.

Considering that other long-standing CBR employees resigned without receiving any compensation, she questioned: «Why would Yáber have paid an indemnity greater than that given to someone who worked as a cleaner in his office?»

«I maintain that this contract was simulated, and the severance payment was received by the duo Migueles – Vivanco, for whom she provided services. Martel, in turn, maintained the false employment for her to work in the home of the Supreme Minister, assuming the costs as a form of payment that was charged to him by the network,» concluded the prosecutor as indicated in the document.

When contacted by Reportea, Fernando Martel defended the hiring: «She worked Monday to Friday, a full office schedule, doing notary work… What she did on the weekends at another person’s house is not my business?».

The Porsche Cayenne and Payments to Migueles

Another line of benefit detected was the sale of a Porsche Cayenne by Yáber to Vivanco. On February 25, 2021, a transfer deed was formalized for $35,000,000, an amount lower than the vehicle’s tax valuation. «Another method of payment for this network of irregular contacts for influencing (judicial) appointments is manifested in the sale of the Porsche, under a price even lower than the tax appraisal for the model with payment that has not been justified as received,» stated the summary, suggesting it was a concealed donation.

Moreover, the investigation confirmed monthly payments of $3,000,000 that Yáber made to Gonzalo Migueles, Vivanco’s partner, who is currently in preventive detention at Capitán Yáber, accused of participating in a scheme aimed at paying bribes in exchange for judicial rulings.

According to Reportea, Migueles held an administrative role at the Conservator of Real Estate of Puente Alto.

CBR employees stated to the cited outlet that Migueles «only attended a couple of times a week, and he managed year-end events and bonuses for the staff.»

The Notarial «Placement Agency» and Parties as Tools

The summary details how Yáber utilized his extensive network of contacts, strengthened by frequent meetings and parties, to influence appointments.

«(Yáber) turned this method into a placement agency for notary positions, which can be concluded by observing the direct relationship between belonging to this interest group and being favored with a position,» determined prosecutor Carla Troncoso.

The investigation particularly emphasizes connections with notaries Rodrigo Ortúzar and Claudio Barrena. Concerning Ortúzar, Reportea revealed transfer records involving Yáber and Migueles exceeding $300,000,000, coinciding with his rapid rise to a lucrative notary position in San Miguel.

«The payments and transfers related to current notary Ortúzar, in my opinion, lack a plausible explanation in a legitimate business,» stated Troncoso.

Hiring Relatives of Ministers Who Supported Him

The document establishes that the hiring of Isabel Ponce, wife of San Miguel Court Minister Luis Sepúlveda, and Miguel Farías Pino, brother of Minister Carlos Farías, constituted a concealed reimbursement for the support both magistrates provided Yáber in the 2018 contest for the CBR of Puente Alto.

Regarding Ponce, who received $1,000,000 monthly, the summary included statements from officials describing her «minimal or non-existent contribution» to conclude that «she was a concealed form of reimbursement to those who supported the conservator not only with their vote but also more than once entered into some decisions of the full body in administrative matters involving Yáber.»

Given the gravity of the evidence, prosecutor Troncoso decided to refer the matter to the Public Ministry.

«I warn that the payments for services that, in my view, lack commercial or legal justification, along with the bank movements involving individuals already under investigation for money laundering, must be reviewed in the criminal court,» she noted.

In her conclusions, the prosecutor established that: «The status of public official does not end at the close of public service hours, because ultimately a position is a burden, not a criminal enterprise, a point the accused apparently fails to understand.»

Sergio Yáber has eight days, starting from last Friday, January 2, 2026, to submit his written defenses to the Court of San Miguel, which will subsequently determine his possible dismissal.
