Private Investigations in Western Germany

DETIX is an investigation agency serving businesses, legal professionals and private clients in North Rhine-Westphalia, Rhineland-Palatinate and Saarland. Missing goods, inconsistent information from a business partner or an untraceable contact each call for a clearly defined investigation. DETIX – Die Ermittler is based in Dieburg near Darmstadt. We arrange assignments with suitable investigators and through our established professional network.

Corporate investigations across the Rhine, Ruhr and Saar regions

Industry, trade and logistics connect businesses across Western Germany. Discrepancies in orders, stock movements or payments can have several explanations. Our CORPORATE INVESTIGATIONS focus on specific inconsistencies. We examine indications of fictitious deliveries, undisclosed business relationships or unfair competition, and document which information can be verified.

Medium-sized businesses and financial service providers also need reliable information about their counterparties. Our company and background checks compare corporate identities, roles and known shareholdings. As private investigators working across NRW and the neighbouring states, we tailor the enquiry to the decision you need to make. A shared address alone does not establish a business connection.

Employee misconduct, surveillance and fact-finding

Missing stock, unusual expense claims or indications of competing outside work require an objective enquiry. Describe specific incidents, including dates, locations and the source of each observation. Our investigators assess the information and discuss the enquiries that are necessary and proportionate. The report distinguishes suspicions from substantiated misconduct.

Surveillance services are considered only where they are lawful and proportionate. We agree the objective, time frames, locations and staffing requirements in advance. In employee-related cases, involve your legal advisers at an early stage. DETIX records observable events and their timing; we do not give blanket assurances that evidence will be admissible in court.

North Rhine-Westphalia: the Rhineland, Ruhr area and Westphalia

An enquiry in North Rhine-Westphalia often involves several locations. Düsseldorf, with its corporate and financial services sector, and Cologne and Bonn may provide starting points for company checks or local enquiries. Across Rhine-Ruhr, we can bring together connections involving logistics in Duisburg, businesses in Essen and Bochum, and commercial contacts in Dortmund within a coordinated assignment.

Around Münster and Bielefeld, we also handle enquiries involving medium-sized businesses and surrounding communities. Aachen can be a starting point for matters involving Belgium or the Netherlands. If you need a private detective in Western Germany, the actual addresses and appointments determine the deployment plan. These locations describe our service area; they are not DETIX branch offices.

Rhineland-Palatinate and Saarland: businesses and border regions

Mainz and Koblenz may be relevant to company or people searches in Rhineland-Palatinate. Ludwigshafen forms part of the Rhine-Neckar economic region, where enquiries can span both sides of the Rhine. For assignments around Kaiserslautern and Bad Kreuznach, we also consider changing business premises and smaller communities. Clients seeking a private investigator in Rhineland-Palatinate can discuss the full circumstances with DETIX.

Trier provides a possible link for matters involving Luxembourg. In Saarland, we handle enquiries in Saarbrücken, Saarlouis, Homburg and Neunkirchen and their surrounding areas. Industry, suppliers and cross-border business relationships may be relevant, alongside private matters. We plan local enquiries and travel around the specific question to be answered.

Digital enquiries, people searches and asset research

OSINT and digital investigations complement local enquiries by analysing accessible online information. We assess the source, date and attribution of each finding. A location on a profile or an old company website does not, by itself, establish a current address or ongoing business activity.

For person and address searches documented former addresses and reliable identifiers help distinguish the right person. For asset, property and ownership investigations we define the properties, companies and shareholding leads to be examined. Occupancy, ownership and business connections are assessed separately. The information that can lawfully be obtained depends on the circumstances.

Belgium, the Netherlands, Luxembourg and France

Suppliers, distributors and business contacts may be based on different sides of a border. DETIX Investigations combines findings in Germany with targeted enquiries in Belgium, the Netherlands, Luxembourg or France. Each enquiry starts with a specific unresolved question, such as a counterparty’s identity, a business address or a named asset.

For each country, we assess suitable research methods and local requirements. Any support from our professional network, additional measures and costs are agreed in advance. An instruction in Germany does not automatically permit the same methods in a neighbouring country. DETIX in Dieburg remains responsible for coordination.

For businesses, legal professionals and private clients

Businesses can seek support with counterparty checks and suspected workplace misconduct. Legal professionals can specify unresolved facts, deadlines and documentation requirements. Private clients may need a lawful address enquiry or clarification of asset-related information. Our private and corporate investigations follow the documented grounds for the enquiry and the agreed objective.

Starting an investigation in Western Germany

We review the necessary initial information and discuss feasibility, proposed measures, fees and expenses. The agreed investigation begins once you have instructed us. Any extension is discussed with you. Your report distinguishes verified facts, leads and unresolved points.

Five questions about investigations in Western Germany

Can you handle a case spanning NRW and Saarland?
Yes. A connected matter can involve several German states. We first map the companies, individuals and appointments by location and date. We then coordinate the research, suitable investigators and travel requirements. You retain one contact for coordination.

How do you investigate missing stock at a logistics business?
Stock discrepancies, delivery records and an outline of the relevant processes provide useful starting points. We discuss which facts remain unclear and which enquiries would help establish what happened. Any investigation into individuals requires a separate assessment of its grounds and lawfulness.

Is general mistrust enough to justify surveillance?
General mistrust alone does not provide an adequate basis. Before an assignment, we assess the specific circumstances, the legitimate purpose and whether the proposed measures are proportionate. In employment-related matters, the legal assessment should be coordinated with your legal advisers.

Can you check a business partner in a neighbouring country?
Yes, where the particular enquiry is feasible and lawful in that country. We need the exact company name, known contacts and the information to be checked. We clarify the local scope and agree additional costs before extending the research.

How are fees and the instruction agreed?
The cost depends on the scope of research, deployment time, staffing, travel and any international elements. After defining the enquiry, we discuss fees and expenses with you. The services, reporting arrangements and any required advance payment are agreed before work begins.
