Court-Usable Investigations in Germany & Europe

German Premium Investigator for International Law Firms, Companies, Insurers and Private Clients

International investigations require more than information.

They require facts.

Facts that are obtained discreetly.
Facts that are documented properly.
Facts that can be understood by lawyers, companies, insurers and courts.
And facts that can support decisions, negotiations, claims or legal proceedings.

Detektei Detegere provides professional investigation support in Germany and Europe for international law firms, companies, insurers, family offices and private clients.

We focus on court-usable findings, structured documentation and discreet field intelligence.

When International Clients Need Reliable Facts in Germany

Many international clients face the same problem.

They have a case connected to Germany or Europe, but they do not have reliable access to local facts.

A debtor may be hiding assets.
A business partner may be misleading investors.
An employee may be violating contractual duties.
A claimant may be exaggerating damages.
A private person may be concealing income, assets or a new living situation.

In these cases, assumptions are not enough.

International clients need a German investigation partner who understands discretion, evidence, documentation and legal sensitivity.

This is where Detektei Detegere comes in.

Investigation Support for Companies

Companies operating internationally often face complex risks.

Fraud, internal misconduct, employee violations, unfair competition, supply chain issues and undisclosed conflicts of interest can cause serious financial and reputational damage.

We support companies with discreet and structured investigations.

Our services for companies include:

We do not provide speculation.

We provide facts, timelines, observations, findings and structured reports.

Investigation Support for Insurers

Insurance cases increasingly involve complex factual questions.

Is the claimed damage plausible?
Is the injury consistent with the person’s actual daily activities?
Are documents, images or statements reliable?
Could digital manipulation or AI-generated content be involved?

We support insurers, claims departments, law firms and loss adjusters with discreet investigations in Germany and Europe.

Our services for insurers include:

Insurance investigations must be proportionate, discreet and carefully documented.

We focus on facts that can clarify a claim and support further legal or internal assessment.

Investigation Support for Private Clients

Private clients often contact us when the situation is personally difficult, financially important or emotionally stressful.

These cases require sensitivity, discretion and a clear understanding of what can and cannot be done legally.

We support international private clients in Germany and Europe with:

  • maintenance and alimony-related investigations
  • investigations into hidden income
  • investigations into concealed cohabitation
  • custody-related fact finding
  • stalking-related documentation
  • infidelity-related clarification
  • address and residence checks
  • background checks
  • discreet surveillance

Private investigations must never be careless.

That is why we assess each case carefully before recommending any action.

Asset Tracing and Debtor Investigations in Germany

International creditors, law firms and enforcement specialists often need reliable information about debtors in Germany.

A person may claim to have no assets.
A company may appear inactive.
A debtor may have changed address.
Business activity may continue through third parties.
Assets may be hidden, transferred or disguised.

We support clients with structured debtor investigations and asset tracing in Germany.

Depending on the case, this may include:

  • address verification
  • residence checks
  • lifestyle indicators
  • business activity research
  • company-related research
  • OSINT investigations
  • field inquiries
  • neighborhood inquiries where legally permissible
  • vehicle and location-related observations
  • documentation for legal follow-up

The aim is not to make assumptions.

The aim is to establish factual indications that can support the next legal, commercial or enforcement step.

Surveillance in Germany and Europe

Surveillance is one of the most sensitive areas of private investigation.

It must be planned carefully, conducted discreetly and documented professionally.

We conduct surveillance in Germany and, through trusted partners, in selected European jurisdictions.

Typical surveillance cases include:

  • employee misconduct
  • sick leave abuse
  • insurance fraud
  • debtor activity
  • private law matters
  • family law matters
  • cohabitation investigations
  • suspected hidden work or income
  • location verification
  • pattern-of-life documentation

Every surveillance assignment requires a legitimate interest, clear instructions and a legally sound approach.

We document observations with time references, factual descriptions and, where appropriate, photographic or video evidence.

Germany-Based Field Intelligence

Online research alone is often not enough.

Many cases require local presence.

We provide Germany-based field intelligence for international clients who need facts on the ground.

This may include:

  • local inquiries
  • address checks
  • residence verification
  • business location checks
  • site visits
  • neighborhood information where permissible
  • discreet documentation
  • coordination with legal representatives
  • structured reporting in English or German

Germany-based field intelligence is particularly useful when international clients need a reliable view of what is actually happening locally.

Frankfurt Region – Strategic Access to Germany and Europe

Detektei Detegere is based in the Frankfurt Rhine-Main region.

This location offers fast access to Frankfurt Airport, one of Europe’s most important international transport hubs.

For international clients, this is a practical advantage.

It allows us to coordinate investigations across Germany, respond quickly to urgent matters and cooperate efficiently with international partners.

Germany is often the key jurisdiction in cross-border disputes, enforcement matters, insurance cases and corporate investigations.

We provide the local investigation support needed to clarify those matters.

Our Reporting Standard

International clients need reports that are clear, factual and usable.

Our reports are structured to provide:

  • case background
  • objective of the assignment
  • investigative measures
  • timeline of activities
  • relevant findings
  • factual observations
  • photographic documentation where applicable
  • summary of results
  • clear distinction between facts and assumptions

We avoid unnecessary speculation.

A professional investigation report must be understandable, precise and suitable for further legal or internal use.

In cross-border disputes, reliable facts and properly documented evidence are essential. The European e-Justice Portal also provides information on the taking of evidence in civil and commercial matters within the EU:
European e-Justice Portal – Taking of Evidence in Civil and Commercial Matters

Confidentiality and Secure Communication

Discretion is essential in every investigation.

We treat sensitive information confidentially and communicate carefully.

Depending on the case, reports and documents can be delivered in encrypted form.

We are used to working with lawyers, companies, insurers and private clients who require a high level of confidentiality.

Typical Cases

A law firm outside Germany needs information about a debtor, defendant or opposing party located in Germany. We verify addresses, conduct background research, check relevant indicators and provide a structured report for legal follow-up.

Company

An international company suspects misconduct, internal fraud or a breach of contractual obligations in Germany. We support the internal review through discreet research, surveillance where appropriate and factual documentation.

Insurer

An insurance company questions the plausibility of a personal injury claim. We conduct discreet observations and research to clarify whether the claimed limitations are consistent with real-life activities.

A private client living abroad needs reliable facts in Germany regarding maintenance, cohabitation, hidden income or residence. We assess the case and provide proportionate investigative support.
