A client from Italy engaged us to investigate his Australian business partner. Within two weeks, we uncovered falsified engineering qualifications, a hidden bankruptcy, and a misrepresented office address — saving our client from a potentially devastating fraudulent partnership.
A husband needed to serve his estranged wife with divorce documents but had been given incorrect addresses for six years. Through targeted workplace surveillance and patient monitoring, we located her residence, confirmed it over multiple days, and later assisted with personal service of legal documents.
Acting for a daughter in England on behalf of her elderly mother, we investigated a husband who claimed to have sold all marital assets during the marriage. What we found — multiple properties held in trusts and alternate names — changed everything for her divorce case.
A wife suspected her partner was meeting someone from his office after finding suspicious messages on his phone. He claimed it was a business meeting. We conducted mobile surveillance and delivered photographic and video evidence of the meetings.
