Words From Clients

  • I would like to thank Marc and the rest of the Investigations team at Nationwide legal, for catching my (now) ex-boyfriend for cheating on me with a freaking gym trainer. Marc was very patient and attentive with me. He said that he will update me daily on anything that he finds. A week later, Marc sent me pictures and video of my ex grinding on his trainer. I’m so glad that I was able to get closure and move on with my life, thanks to Nationwide’s expertise. If you need a great investigator who will have your back from start to finish, then Marc and Nationwide Legal is the company to go with.

  • I’ve used Nationwide twice now, for different matters. They were extremely professional, reasonably priced, and responded quickly. The staff kept in close contact with me throughout the entire process, giving me updates through a very tough time. They kept me calm and solved both of my issues so quickly. The communication and reliability keeps me going back.

  • Three weeks ago, I called Nationwide legal regarding doing a skip trace on my father. I Have not seen my father since I was eight months old. I needed to make amends for my personal life. So I spoke with Marcus and he was very informative with the pricing, as well as the details on what is needed to look for my father. It hasn’t even been 48 hours since the trace started and he was able to get me an address, as well as a phone number to contact my father. Now I’ve spoken with my father and we are going to meet each other for the first time this summer. I would like to thank Marcus and the investigations team, for their hard work and diligence on locating my father. If you need to find someone or track somebody down, then this company is the best at what they do.
