Greyline Investigations Limited is registered in England and Wales, UK based and UK accountable, with named in-country partners in Nigeria for the work that genuinely requires local capability: Land Registry tracing, CAC corporate verification, and site verification. The lead investigator on every cross-border engagement remains UK based and personally accountable for the integrity of the in-country output.
Families and individuals across the UK's Nigerian and wider West African diaspora face a recurring set of needs that generic private investigators are not built for: verifying a prospective spouse or partner met abroad, confirming a business or investment opportunity in Nigeria is genuine before money moves, tracing assets across a border most UK firms cannot reach, and serving legal process on someone resident in Nigeria. Greyline was founded specifically to close that gap, combining UK regulatory accountability with named, vetted partners on the ground.
Every engagement begins with a confidential inquiry and proceeds to a written scope before any work is committed.
