I had outstanding experience and results with Orange Detective Agency. I reached out from across the country (PA) to get help with obtaining 1986 divorce records from Orange County. The person answering the phone was friendly and helpful and she put me on the phone with Ali. He was knowledgeable, personable and professional. He made me comfortable paying for services in advance sight unseen. Ali also offered a way to cut down the cost to suit my budget.

I received 62 pages of documents quickly and conveniently. On top of that, Orange Detective Agency also gave me information I needed to access my marriage records in NV at no additional cost. That was an outstanding gesture that helped me without my even needing to ask. Highly recommend these folks.

As a practicing attorney in California, I trusted Ali and his team to help collect on a difficult judgment. They identified several methods of enforcement, including assets and employment. They kept me informed, and were always receptive to calls and emails regarding the status on my case. I was recently able to collect on my judgment in full, thanks to the hard work of these detectives. I would recommend them to anyone seeking investigators who are diligent, honest, and provide results.

Ali went above and beyond to help me with my inquiry. He communicated my options in a clear and professional manner. It was obvious to me that he genuinely cared for his clients. I felt like I was in good hands with him. I definitely recommend this firm.
