Benfica President's Real Estate Firm Sued Over €500K Loan

Sport Lisboa e Benfica's president Rui Costa is facing renewed scrutiny after his real estate company, 10 Invest, was sued by former club vice-president Luís Mendes over a €500,000 loan that took months to repay. The debt, which increased to €502,445 with interest and legal costs, was finally settled in June 2025—but not before exposing cracks in both the Carnaxide luxury development driving the dispute and the internal governance of Portugal's most storied football club.

Why This Matters

• Corporate governance questions: A sitting club president's personal financial entanglements with a senior executive raise red flags about conflicts of interest and transparency at Benfica.

• Legal exposure: 10 Invest now faces four civil lawsuits, three tied to the troubled Dream Living project, with completion pushed to late 2026 or early 2027.

• Economic risk: With artificially inflated assets and €45 M sunk into a stalled development, the case underscores liquidity pressures in Portugal's overheated real estate market.

The Loan That Went to Court

Luís Mendes, who served as Benfica's financial administrator and vice-president until June 2024, extended the half-million-euro loan to 10 Invest in what both parties initially framed as a personal favor between colleagues. But when repayment stalled, Mendes filed suit on January 21, 2025, at the Oeiras District Court, seeking recovery plus accrued interest and court fees.

The move was unusual not only for its timing—coming seven months after Mendes resigned—but also for the public airing of financial friction between two men who once formed the executive backbone of Portugal's largest football institution. Mendes confirmed the loan's existence on his LinkedIn profile late Wednesday evening, hours after the investigative magazine Sábado published its exposé. He insisted his departure was driven by "strategic and governance disagreements," citing concerns over the club's deteriorating financial equilibrium and sports policy, not the unpaid debt.

Yet multiple sources suggest the loan dispute contributed materially to the rupture. Mendes had grown increasingly vocal about "non-executive interference" in club decisions and what he called a return to the "dinosaur era" of governance under former president Luís Filipe Vieira, whose shadow still looms over Rui Costa's administration.

Dream Living: A €45 M Headache

At the heart of the controversy sits Dream Living, a six-building, 90-apartment luxury condominium in Carnaxide developed through a partnership between 10 Invest and JPS Group. Launched in 2018 with a projected investment of €45 M, the project has lurched from delay to delay, hammered by the COVID-19 pandemic, the Ukraine war's supply chain shocks, labor shortages, and what the developers describe as "technical difficulties related to terrain complexity."

More than five years on, only a fraction of the units have been delivered, and buyers are furious. 10 Invest is now defending itself in three separate lawsuits tied to Dream Living, with complaints ranging from missed delivery deadlines to alleged defects in completed apartments. A fourth civil action, unrelated to Dream Living but still targeting the company, adds to the legal burden.

In a statement released Wednesday night, 10 Invest acknowledged "operational constraints in the pace of execution" but flatly denied economic distress. The company insisted it maintains "full operational and financial stability" and continues to meet all contractual and financial commitments. Completion of Dream Living is now forecast for late 2026 or early 2027—nearly a decade after the project broke ground.

But investigative outlets paint a darker picture. Reports indicate that 10 Invest's balance sheet features artificially inflated assets and credits against shareholders that may mask either a financial collapse or off-the-books loans to the owners themselves—Rui Costa among them.

What This Means for Residents

For Benfica members, the scandal raises urgent questions about accountability and conflict of interest at the top of a club that runs on member fees, ticket sales, and broadcast revenues. Portuguese corporate law and the club's own statutes require board members to disclose financial entanglements that could compromise their duties. The fact that Benfica's president needed a €500,000 bridge loan from his own vice-president—who also oversaw the club's finances—suggests either a breakdown in governance protocols or an uncomfortably cozy relationship between personal business and institutional oversight.

For buyers of Dream Living apartments, the outlook remains uncertain. Portugal's real estate market has experienced a construction boom over the past five years, fueled by foreign investment. However, that expansion has left some developers overextended, and buyers caught in stalled projects often face years of legal wrangling to recover deposits or secure compensation. Portuguese consumer protection law (Lei nº 17/2008) allows buyers to seek deposit refunds after repeated missed deadlines, though enforcement typically requires legal action through the civil courts. The Carnaxide development is now a cautionary tale for anyone considering off-plan purchases in Portugal's luxury segment.

More broadly, the case underscores liquidity risks in Portugal's property sector. Standard luxury residential projects in the Lisbon metropolitan area typically complete within 3-4 years. With Dream Living now in its eighth year and still incomplete, construction delays of this magnitude are unusual. With interest rates elevated and construction costs still volatile, even well-capitalized developers are feeling the squeeze. 10 Invest's troubles, combined with the lawsuit tally, suggest a company operating on thin margins—a scenario that could ripple across the partners and subcontractors involved in Dream Living.

Governance Under the Spotlight

Luís Mendes departed Benfica in June 2024, just two days before a General Assembly where the club's budget was to be presented. At the time, his exit was framed as a mutual parting over strategic differences. But his subsequent criticisms—delivered in a detailed interview with the sports daily Record—were scathing. He accused the administration of reverting to the "Vieirismo" model of governance, where decision-making power was concentrated among non-executive figures and insiders from the Vieira era, rather than professional managers.

Rui Costa responded publicly at a September 2024 General Assembly, saying he still did not understand the "real reason" for Mendes's resignation and suggesting the former vice-president should have explained himself directly to members. Costa's framing implied Mendes abandoned ship at a critical juncture, leaving unanswered questions about the club's financial posture.

The loan dispute, however, offers a plausible alternative narrative: that the two men's relationship had soured not just over club politics but also over personal financial obligations that went unmet. The fact that the debt was paid only after legal action suggests 10 Invest was indeed facing cash flow pressure in early 2025, contradicting the company's current denials of liquidity trouble.

Looking Ahead

Benfica remains Portugal's most commercially successful club, but the Costa presidency has been dogged by questions over transparency and continuity with the Vieira regime. The Mendes-Costa loan affair will fuel demands for stricter disclosure rules and clearer firewalls between board members' personal ventures and club operations.

For 10 Invest, the stakes are high: complete Dream Living on schedule and settle the outstanding lawsuits, or risk reputational damage that could spill over into Costa's role at Benfica. The company has pledged "transparency" and reaffirmed its commitment to project completion, but with four active court cases and a track record of missed deadlines, investors and buyers will be watching closely.

Meanwhile, Luís Mendes has closed the chapter on his Benfica tenure with a terse LinkedIn post, lamenting that the financial dispute has become a distraction "at a particularly important moment for the club." Whether that moment involves on-pitch performance or off-field housecleaning remains to be seen—but for now, the spotlight is squarely on Rui Costa and the real estate venture that turned a corporate ally into a legal opponent.
