FAQ's
How do you choose the closest team within the Algarve?
We coordinate from Faro and from agents distributed across the region, which allows us to mobilise whoever is physically closest to the case — whether in Vilamoura, Lagos or Tavira — without relying on long-distance travel.
Do you work with foreign clients and owners?
Yes. We provide services to foreign residents in the Algarve and to property owners living outside of Portugal who require on-site inspections. The consultation and final report can be in English. For those abroad, the entire process—case opening, follow-up, and report delivery—can be done remotely.
Do they conduct monitoring in hotels, resorts, and marinas without raising suspicion?
Yes, and it's the most frequent scenario in the region. A holiday environment has its own rules: private spaces with security, very busy common areas, and a standing observer who immediately stands out. We work with passive surveillance and long-range equipment, which allows us to document movements in Vilamoura, Albufeira, or Lagos without the team's presence being noticed.
Can you locate anyone who is passing through the Algarve?
Yes. The tourist nature of the region means working with short stays and specific entry and exit points, most notably Faro Airport. In these cases, the decisive factor is speed: the sooner the case is opened, the greater the likelihood of a result before the person leaves the region. We act with the same promptness in both the Barlavento and Sotavento regions.
Are they investigating cases that cross the border into Spain?
Yes. In Vila Real de Santo António, Castro Marim and Alcoutim it is common for a case to continue on the other side of the Guadiana River. We are member number 1326 of the APDPE — Asociación Profesional de Detectives Privados de España (Professional Association of Private Detectives of Spain) —, which allows us to coordinate our work with Spanish colleagues and continue the investigation in Spain without losing track of the case.
Do they conduct investigations related to real estate and rentals?
Yes, it's a recurring request in the Algarve. We verify the actual occupancy of rented properties, situations of unauthorized subletting, operation of local accommodation without the owner's knowledge, damage and abandonment of property, and confirmation of the condition of properties for owners residing abroad.
Do you investigate cases linked to gambling or casinos in the region?
Yes, this is a fairly regular request given the presence of casinos and nightlife in the region, usually associated with infidelity cases or family financial risk management.
Do they help locate heirs and assets in the Algarve?
Yes. It's a recurring request in a region with a strong presence of foreign property owners and second homes. We locate heirs, identify properties and assets, and investigate undeclared assets, supporting clients and law firms with factual and verifiable information.
