Nigeria is Africa's most populous country and one of its largest economies. Lagos is a continental hub for finance, fintech, media, consumer goods and trade. Abuja is the seat of government and a centre for public contracting. Port Harcourt anchors the oil and gas industry of the Niger Delta, and Kano remains a key northern trading city. Nigerian businesses are dynamic and ambitious, and many international companies build successful partnerships here. The ones that succeed treat verification as a standard part of doing business.

Our Investigation Services in Nigeria
Due Diligence in Nigeria
Our due diligence in Nigeria covers partners, distributors, suppliers, borrowers, acquisition targets and investors. We research company records at the Corporate Affairs Commission (CAC), court information, regulatory databases and media, identify owners and directors and check sanctions, PEP and adverse media exposure. Discreet local enquiries test reputation, capacity and relationships with officials.
Corporate Investigation in Nigeria
Our corporate investigation in Lagos and across Nigeria covers fraud, embezzlement, procurement fraud, stock and cash diversion, kickbacks and employee misconduct. Our fraud investigation in Nigeria also covers business email compromise, fake supplier schemes and payment diversion affecting international companies.
Background Check in Nigeria
Our background check in Nigeria services verify identity, education, employment history and reputation for managers, finance staff, agents and partners, with consent and in line with the Nigeria Data Protection Act 2023. Degrees and professional certificates are verified directly with issuing institutions, which matters in a market where forged certificates are a known risk.

Brand Protection in Nigeria
Our counterfeit investigation in Nigeria covers major markets in Lagos, Onitsha, Aba, Kano and other commercial centres, as well as online sellers. We focus on pharmaceuticals, auto parts, lubricants, electrical products, beverages and cosmetics, carry out test purchases, trace goods to importers and warehouses and support raids and seizures with the authorities.

Verifying Counterparties Before Money Moves
Many fraud losses involving Nigeria follow the same pattern: an international company pays a new supplier, buyer or agent that looks legitimate on paper, and the money disappears. Company documents may be real but belong to a dormant business, bank details may be changed through a compromised email, or the "factory" may not exist. Our investigators verify the company, the people, the premises and the bank account ownership before payment, and trace funds when fraud has already occurred.
Oil and Gas Sector Investigations
The oil and gas sector remains central to Nigeria's economy and to many international companies' presence in the country. Investigations here often involve contractor and vendor vetting for international oil companies, crude and product theft, diversion of fuel, local content partner verification and allegations of corruption in contracts. Our investigators understand how the sector works in Port Harcourt, Warri and Lagos, and conduct enquiries with care in a sensitive environment.
Counterfeit Medicines and Consumer Safety
Counterfeit and substandard medicines are a major public health risk in Nigeria. Fake products enter through ports and land borders and move through open markets into pharmacies and patent medicine stores. Our investigators secure samples for laboratory testing, trace supply chains to importers and warehouses and support enforcement with the authorities, helping pharmaceutical companies protect patients and their brands.
Working Safely
Security conditions vary significantly across Nigeria. We assess risks before field work, plan enquiries around local conditions and never put investigators or sources in unreasonable danger. Where on-the-ground work is limited, we explain what can be achieved through other means.
