How to Instruct a Private Investigator

Instructing an investigator for the first time can feel daunting. This guide walks through what to look for in a firm, how the process works, and what information helps an investigator get started.

When to instruct an investigator

Businesses, solicitors and insurers instruct investigators for a wide range of reasons: validating a suspicious claim, checking a prospective partner or acquisition, locating a debtor or assets ahead of enforcement, or gathering evidence in a dispute.

If you need verified facts rather than assumptions — gathered discreetly and lawfully — it is usually worth a conversation.

What to look for in a firm

Look for a firm that works to a clear, lawful and proportionate approach, that is comfortable explaining what it can and cannot do, and that reports its findings in a structured, usable way.

For commercial matters, a firm that works with businesses, insurers and solicitors will understand the standards your decision or your case needs to meet.

The instruction process

It usually runs in five steps: an initial enquiry; a confidential consultation to understand your objective; a proposal setting out scope, approach and cost; the engagement itself; and a clear report of findings you can act on.

A good firm keeps you appropriately informed throughout, and is honest if an objective is not achievable.

What information to provide

The more context you can share at the start, the more efficient the work. Useful information includes the background to the matter, any documents or references you already hold, the specific question you need answered, and any deadline you are working to.

Confidentiality

A professional firm treats every enquiry in the strictest confidence. You should feel able to discuss your situation openly in order to get the right advice.
