When to Instruct a Private Investigator

The question almost always arrives in the same shape: is it too early, or already too late? Too early, and the enquiry costs money to establish what was already known. Too late, and the traces have faded, the companies have changed name, the witnesses have forgotten. The right moment sits between the two, and it can be recognised by a handful of fairly clear signals.

Recognising a factual dead end

A factual dead end is not a lack of opinion; it is a situation in which several versions coexist and none can be verified with the means at your disposal. You have searched, asked and compared, and the doubt remains because a material element is missing, not because conviction is missing.

Three signs usually indicate that point. The answers you receive contradict each other on checkable points. The documents available always stop at the same place. And the research you conduct yourself is becoming visible to the party concerned, which changes how they behave.

A fourth, quieter sign concerns time. When manual checks take more than a few days and require skills you do not have — reading foreign registers, understanding an ownership structure, conducting field interviews — a professional becomes a saving rather than a cost.

The situations that justify a mandate

In practice, requests fall into a few stable families. A commercial dispute where the opposite case rests on assertions that are never substantiated. A broken business relationship accompanied by suspicions of client poaching. A candidate for a sensitive role whose record contains unclear periods. A property transaction or acquisition where the true identity of the counterparties remains uncertain.

More personal matters are added to these, and they are often more delicate: verifying information received anonymously, tracing a person in a family or succession context, clarifying a disagreement between shareholders that threatens to block a company entirely.

The question of urgency deserves to be asked out loud. Some checks can be completed in days; others, particularly those involving foreign registers or interviews, require several weeks. A serious firm states that timeframe before starting, not after the retainer is paid.

What an enquiry does not replace

A private investigation replaces neither court proceedings, nor a financial audit, nor technical expertise. It does not « prove » anything in a procedural sense: it establishes facts, documents their origin, and allows a lawyer to decide on strategy afterwards. Confusing those two registers leads to disappointed expectations and, occasionally, to unusable reports.

Nor does it replace a decision. A well-built report reduces uncertainty; it does not decide on behalf of an executive, a family council or a partner. That distinction should be set out in writing from the outset, so the enquiry does not become the pretext for indefinite postponement.

It also happens that an enquiry concludes there is no anomaly. That is a useful result, often the hardest to obtain, because it requires searching with the same rigour as if one expected to find something. A documented negative report is worth more than a favourable one nobody can verify.

The cost of waiting

Waiting has a price that is rarely calculated. In due diligence, every week of delay brings the signing closer and makes renegotiating the terms more expensive. In a shareholder conflict, unverified information circulates and turns into rumour that is difficult to correct. In litigation, limitation periods run regardless of hesitation.

There is an internal cost too: teams working on a file without knowing whether its premises are sound. Untreated uncertainty turns into repeated meetings, postponed decisions and, occasionally, resignations.

Acting too quickly also causes damage. An enquiry launched before the object, the scope and the expected deliverable have been defined tends to produce a bulky document that answers no precise question. Time spent framing the request is never wasted.

Signals of premature framing

• The mandate begins with a desired conclusion rather than a question.
• The geographic scope remains undefined.
• Nothing is said about how the report will be used.
• The budget is fixed before the checks are defined.
• The party concerned already knows about your suspicions.

None of these signals invalidates the project, but each delays its success. Reconsidering the framing costs a few exchanges; reconsidering it after three weeks of fieldwork costs the mandate.

One further point deserves attention: the number of requesters. A mandate split between several voices produces contradictory scopes and reports that nobody validates.

A final rule settles the question of timing: if the missing information would change your decision, it justifies verification. If it would not, the enquiry is curiosity rather than need, and that is a poor use of available resources.

An initial confidential consultation establishes what the request really is, identifies what can be verified within a useful timeframe, and states plainly what cannot. It commits you to nothing. These pages are editorial information and do not constitute legal advice.
