Our most comprehensive pre-commitment investigation, for the moment before marriage, cohabitation, joint property purchase, or relocation.
Built for the moment before a major life decision, marriage, cohabitation, joint property purchase, business partnership with a romantic partner, sponsorship of a partner's visa, or relocation to be with someone. These are decisions that, if wrong, are catastrophic financially, emotionally and legally, and the cost of the investigation is a fraction of the cost of being wrong.
An annotated evidence report with every finding sourced, dated and cross-referenced, prepared in a format suitable for civil proceedings where relevant, divorce petitions, prenuptial disputes, or financial remedy applications, concluded with a debrief call with the lead analyst.
Full digital footprint sweep: social media, dating and lifestyle platforms, reverse image search, and forum/public mention checks across 300+ platforms
Behavioural intelligence: a Digital Behaviour Intelligence Report covering persona analysis, authenticity assessment and consistency scoring
Identity and document verification: marriage/divorce record checks, document authentication, and professional licence verification
Criminal and legal record checks: UK and country-of-origin equivalents, sex offender registers, and adverse media screening
Physical field verification where required: family and associate verification, source-country checks, and neighbourhood enquiries via Greyline's in-country network
Runs across five layers, digital footprint, behavioural intelligence, identity and document verification, criminal and legal record checks, and, where required, physical field verification in the subject's country of origin, each cross-referenced against the others before the report is finalised.
Where required, yes, physical field verification is conducted through Greyline's network of trusted in-country investigators, including family/associate verification and local neighbourhood enquiries. Timelines and scope for field work are confirmed at intake.
It's prepared to a format suitable for civil proceedings, every finding sourced and dated, for matters such as prenuptial disputes or financial remedy applications. Whether it's sufficient for a specific proceeding is confirmed with you and, where relevant, your solicitor at scoping.
Relationship Authenticity Verification answers a narrower question: is this person and the relationship what they appear to be. This assessment is built for the moment before a major, hard-to-reverse decision and runs five layers deep, digital, behavioural, identity and document, criminal and legal, and, where required, physical field verification, rather than a single focused check.
General due diligence ahead of marriage, cohabitation, or a significant financial commitment is a common and entirely reasonable reason on its own. You do not need a specific suspicion to want a clear, factual picture before a decision that is difficult to reverse.
The desk-based layers are built entirely from publicly available information and lawfully obtained records, without contacting the subject. Physical field verification, where instructed, is conducted discreetly through vetted in-country investigators rather than direct contact, unless direct verification is specifically agreed as part of your scope.
The lead analyst walks you through every finding, what was verified, what could not be verified, and what any inconsistencies actually mean in practical terms, so you leave with a clear picture rather than just a written report to interpret alone.
Every enquiry is reviewed by an analyst and routed to a scoping call, a fixed fee is confirmed in writing before any work begins.
