Client testimonials

My husband was visiting Thailand (Pattaya) by himself every year to play golf. When he decided to make three trips in one year I started to become wary about what he was up to, and his search history gave me more clues. When I researched the "industries" of Thailand more thoroughly I started to realize what might be going on.

I was very wary about hiring a private investigator as I have never done so before. The service that I received was very good. They were on hand to explain things to me and offer advice on things that I would otherwise have struggled with.

Although I was devastated to have my suspicions confirmed it was better to find out. I am very pleased with the results and the service. I would recommend this company to anyone.

If you are dating a Thai woman and getting into a relationship then you NEED to use a service like this or risk being scammed. We all think that it could never happen to us but it does. I was nearly scammed and this service helped me dodge a bullet.

I was dating a Thai woman who I met through a dating app. We talked every day but it was when she started to tell me stories about her needing money that I became suspicious. Reading all the horror stories online about dating scams in Thailand I decided to check her out before things went further.

It only took one day of investigation to find out that her story was filled with holes. On the second day we discovered that she was living with a Swiss man and was probably speaking to a dozen other men.

If I had never used a private investigator then I would still be in a relationship with Pim and wasting my hard earned cash on her. I was kept in touch through every step of the investigation and really glad that I decided to go ahead. I would highly recommend this service to anyone.

I've used Thailand Private Investigators for several jobs over the years. Originally we started by checking out my Thai girlfriend and making sure there were no hidden surprises in store. As I made the move to live in Thailand and setup business, I've used the company for due diligence and background screening on my employees. They were able to complete 36 criminal record checks for me within 2 days, which really helped us to kick start the business.

I've always received a great service, the staff are very responsive and happy to explain things and to answer questions. I would recommend this firm for anyone that doesn't want to find themselves being ripped off in Thailand!
