The Portugal Judiciary Police opened a record 177 fraud marriage cases during 2025, a surge that investigators attribute largely to the government's decision to abolish a popular visa pathway that previously allowed irregular migrants to legalize their status through employment. With that option closed, foreign nationals have turned increasingly to sham marriages with Portuguese citizens—many of them struggling with addiction, poverty, or unemployment—to secure residency permits.
Why This Matters
• €33,000 price tag: Migrants are paying organized networks up to €33,000 per marriage to secure EU residency rights.
• Criminal penalties: Both spouses face 1 to 5 years in prison, while organizers risk 2 to 6 years if convicted.
• Schengen exit strategy: After obtaining Portuguese residency, most foreign participants leave for other EU countries, complicating enforcement.
• Vulnerable recruits: Networks target drug users, homeless individuals, and the unemployed in Lisbon and Porto metropolitan areas through social media and word-of-mouth.
The Numbers Behind the Spike
Portugal saw its fraud marriage investigations jump from just 48 cases in 2023 to 112 in 2024, then to 177 during 2025. By comparison, authorities opened only three such probes in 2022. The Portugal Ministry of Justice statistics portal confirms this trajectory, marking 2025 as the most prolific year on record for this particular crime.
Investigators attribute the increase to the June 2024 repeal of the "manifestação de interesse" mechanism, which had allowed tourists entering on short-stay visas to apply for residency if they could prove tax and social security contributions from Portuguese employment. The pathway was scrapped amid political pressure to tighten immigration controls, leaving thousands of undocumented workers without a lawful regularization route.
Algerian and Tunisian nationals account for the largest share of new cases, followed by smaller numbers from Nigeria, Senegal, Guinea-Bissau, India, Pakistan, and Bangladesh, according to the Judiciary Police.
How the Networks Operate
The fraud schemes function as vertically integrated criminal enterprises. At the top sit mentors or organizers who coordinate the entire operation. Below them, recruiters—often known as "angariadores"—canvas vulnerable communities for Portuguese citizens willing to enter paper marriages. Those recruits, predominantly women but also men, receive payments ranging from €1,500 to €5,000 per ceremony, though some report being coerced through threats after initial contact.
Recruitment takes place on social media platforms and through personal referrals. The Judiciary Police note that targets are overwhelmingly people facing drug dependency, unemployment, homelessness, or family breakdown, concentrated in the Lisbon and Porto metro zones where migrant pressure is highest. Once a Portuguese "spouse" is secured, the network matches them with a foreign client who pays the larger fee—up to €33,000—for the full service, which includes document preparation and legal support.
Dismantling Networks: Operation Digital Alliance
In July 2025, the Judiciary Police dismantled one such network in "Operation Digital Alliance," detaining 58 individuals, most of them Portuguese brides. Investigators estimate that ring alone facilitated at least 60 fraudulent marriages. Legal advisers and document forgers sometimes feature in these structures, authenticating false paperwork to satisfy registry office requirements.
After the marriage is registered, foreign participants typically wait only long enough to receive their residency card before relocating elsewhere in the Schengen Area, making follow-up enforcement difficult.
What This Means for Residents
For Portuguese citizens who agree to these arrangements, the legal risk is substantial. Law 23/2007, which governs immigration and expulsion, imposes prison sentences of one to five years for anyone who marries solely to secure a visa, residence permit, or nationality. Those who repeatedly organize or facilitate such unions face two to six years behind bars. Even attempted fraud is prosecutable.
In practice, Portuguese courts often hand down suspended sentences to first-time offenders—typically 18 months suspended for an equal period—though repeat involvement or leadership roles draw harsher penalties. Foreign participants lose any residency rights obtained through fraud and face deportation.
The offense also triggers civil consequences: sham marriages are voidable under Portuguese Civil Code provisions for lack of genuine consent. Registry offices in Portugal are now required to flag suspicious applications to the Judiciary Police and the Institute of Registries and Notaries, creating a front-line detection system.
Detection and Enforcement
Most fraud cases come to light through anonymous tips, alerts from civil registry offices, or international cooperation channels. The Judiciary Police report that as investigations unfold, common patterns emerge—the same recruiters, repeated use of specific addresses, identical legal representatives—pointing to organized networks rather than isolated incidents.
The European Union's free movement directive allows member states to refuse, withdraw, or terminate residence rights obtained through abuse of rights or fraud. EU guidance encourages coordination among immigration, police, and registry authorities, and Portugal has increasingly relied on these frameworks to share intelligence with counterparts in Spain, France, and elsewhere in the Schengen zone.
Investigations often begin when registry officials notice irregularities: couples who cannot answer basic questions about each other, addresses that host dozens of purported spouses, or foreign applicants who disappear shortly after the ceremony. The Portugal Judiciary Police now conduct background checks on both parties when red flags appear, cross-referencing social media activity and financial records.
Broader Context: Visa Pathways and Immigration Policy
The abolition of the manifestação de interesse scheme, introduced to address labor shortages and regularize workers who arrived irregularly, processed tens of thousands of applications before its cancellation. Critics argued it incentivized illegal entry; proponents countered it reduced exploitation and brought workers into the tax system. Its abrupt end left an estimated 400,000 undocumented migrants in Portugal with few legal options, creating fertile ground for criminal networks promising alternative paths to residency.
Across the EU, the abolition of visa amnesty programs has consistently correlated with upticks in sham marriage enforcement. The Netherlands requires foreign nationals without permanent residency to present police clearance before marrying, while Spain criminalizes fraud marriage with similar penalties.
Government and Police Response
The Portugal Cabinet has not announced plans to reintroduce a regularization mechanism, leaving enforcement as the primary policy response. The Judiciary Police have increased resources for fraud marriage investigations, establishing dedicated units in Lisbon and Porto and training registry staff to identify suspicious filings.
Authorities emphasize that prosecution extends beyond the immediate spouses to encompass anyone facilitating the transaction. In the July 2025 operation, charges included forgery, criminal association, and immigration fraud, with some suspects facing cumulative sentences exceeding a decade if convicted on all counts.
Legal experts note that suspended sentences for Portuguese participants—common in first-offense cases—do little to deter involvement when the financial incentive remains high and enforcement resources are stretched. Advocacy groups have called for social intervention programs targeting the vulnerability that makes citizens susceptible to recruitment, though no such initiatives have been funded at scale.
What Lies Ahead
With the manifestação de interesse closed indefinitely and no replacement pathway on the horizon, the Judiciary Police expect fraud marriage cases to remain elevated throughout 2026. Detection mechanisms have improved, but the fundamental economic calculus—a Portuguese citizen in precarious circumstances can earn several months' wages for a few hours at a registry office—remains unchanged.
For foreign nationals, the risk-reward equation is even starker: €33,000 represents a significant sum, but it secures access to the entire Schengen Area and, after five years of residency, a pathway to Portuguese nationality. That prize keeps demand robust despite the criminal penalties and deportation risk.
Registry offices now scrutinize mixed-nationality applications more closely, and the Institute of Registries and Notaries has issued internal guidelines for flagging high-risk filings. Whether these measures will curb the fraud market or simply drive it further underground remains an open question as Portugal navigates the tension between immigration control and the social vulnerabilities that organized networks exploit.
