Investigative support for lawyers and their clients — careful fact-finding, documented for case use.
Family Law Investigator Services
Family proceedings turn on facts that are often disputed: living arrangements, care of children, income and lifestyle questions, and whether orders are being followed. Our family law investigator services support counsel and clients with careful fact-finding, background research, locates, and documented observation — the same work described on our family law investigations page, scoped to the needs of your file.
Civil Litigation Investigator Services
In civil matters, we support litigation teams with witness location and interviews, background and asset research, skip tracing and process serving support, and OSINT research — gathered lawfully and reported clearly, as set out on our civil litigation support page. We agree the scope with you in advance, keep you informed as the work proceeds, and finish with a report your team can build on.

We take instructions from you or your client, agree a clear scope, and report our findings in a documented form your file can build on. We are investigators, not lawyers — we gather and verify facts; legal advice and strategy stay with you.
We gather information lawfully and document how we obtained it, which is what makes findings usable. Whether specific material is admissible is a question for the court and for your legal judgement — we will always tell you how our work was done so you can assess it.
Yes. Many clients come to us first and later involve a lawyer; others are referred by their lawyer. Either way, we keep communication clear about who our client is and what we were asked to do.
Cost depends on scope, time, travel, and complexity. We agree the scope and an estimate with the instructing party before we begin — see how much a private investigator costs.
