The pieces in this category are written by licensed, working private investigators, not marketers, and are intended to give in-house counsel, claims teams, compliance officers and individual clients a realistic view of what is achievable, lawful and admissible in modern EU-based investigative work. ### What you can expect from this category Articles cover scoping decisions, lawful evidence collection, chain of custody, GDPR and Czech procedural compliance, working with counsel, and how findings are typically presented to courts, regulators or insurance committees. Where useful, we anonymise real engagements to illustrate practical trade-offs without disclosing client identities. ### Working with Exero Group If a topic in this category mirrors a matter you are facing, you can request a confidential scoping call. We will tell you whether the case is in scope, what realistic outcomes look like, what evidence is likely to be admissible in your forum, and what it will cost. There is no obligation, and intake conversations are protected by professional confidentiality.
