Recent Reviews

"I'm not including my name, as I used Actio for Private Investigation, but I'm reviewing as I'm grateful for their service. I work a lot abroad and due to the pandemic I haven't been able to come back in to Thailand since it locked down. I was worried my wife of 1 year, may be seeing someone else, for reasons I won't get in to.

They carried out their investigation over 2 weeks in Bangkok where she lives. They were very thorough, professional and discreet. I won't say what they found, but let's just say I'll be using their legal consultancy throughout the divorce. My advice would be, if you have doubts or concerns, use Actio to get you some answers"
Private Investigation in Bangkok Review
Discreet Customer
Managing Director
"I'm involved in a company financing consulting service. We have used Actio numerous times for the one service. They help us with quite few things and I get along with them on a personal level not just professional. Which is why I'm being so kind to write this review. Every time we need an asset search, they are our only go to guys. We have a common type of case, where a company is seeking finance, and when perform an asset search, we find find they are artificially inflating their total asset value, to use as collateral to borrow a bigger sum than they should be able to. As you can imagine this is information we need to know. Actio is very adept at getting this information for us, every time."
Director Of Operations
"I had been dating a Thai woman for around 3 years and was deeply in love with her. We had planned so much together and had bought a house for us to live in and planned on having kids soon too. I had visa issues and had to leave my job. I had to go home which was heartbreaking.

I left her for a few months while I went home and started the Visa application process again and tried to find a job. We talked all the time but she started to become a little distant and a friend of mine said they seen her with another man. I asked her about it and she denied. I hadn't seen her in months so I got suspicious. I decided to hire a PI to look into it for me. They followed her for a week and carried out a background check on her.

They found out she was already married and and had a kid. Not only that but she was living in my home with her husband and his parents. I feel so completely used by her and cannot believe it. Actio really helped me here and gave me real steps that I can take."
Financial Advisor
"I've used Actio for several services, background checks on employees I am thinking of hiring is a common one. I have difficulty finding good staff, like all businesses. I have used Actio when doing due diligence before hiring managing staff, I didn't bother with regular customer service staff. With more senior staff I needed to know more. Out of the 6 times I've used them for background checks, they were able to produce the information I needed each time. It was really interesting and I the information I received played a role in my decision making each time. Out of the 6 background checks, I hired 2 people and the other 4 I decided weren't a good fit for my company."
Mystery Shopping service in bangkok review
Samboon Thongkham
Managing Director
"I'm writing a review and not giving my real name, I feel I have the classic story of the cheated on wife. I feel that writing this will help other women get the courage to find out the truth. My husband has been working late for years, while I stayed at home in the evenings in our apartment with the kids. I had suspicions of his late nights, unusual excuses and being over protective of his phone amongst other things, for years. When I would ask him about it, he would get defensive, annoyed and shut me out. Then there was something that happened, that pushed me over the edge, I googled how to find out if your husband is cheating and found Actio. I am upset as I write this, but I should have sought professional help sooner. I had these suspicions for 4 and half years, before something happened to tip me over the edge. If your reading this, my advice is find out now, don't wait years. If the thing that I won't mention didn't push me, a decade could have went by with us both living a lie. We are now separated and we are having an amicable divorce for the sake of the children."

Private Investigation Thailand

A Unique Style of Private Investigation

We don’t use a one size fits all approach with just one investigator. Every client is unique and has unique needs and concerns. A large corporate investigation client is a very different ball game from investigating to see if a wife or husband is cheating.  We aim to provide the absolute best service in all investigation cases, and here’s how:

 Other private investigation services, will have a couple generic private investigators that they use for all cases, but not us. With a large network of specialist investigators, we will consult with you, to understand your specific needs and assign the perfectly specialised investigator or investigators to your individual case. No other service in Thailand can offer this level of case to case expertise.

We are also unique in that customers know they we are an officially registered company in Thailand, with the DBD. This is important as the client knows we are an official company in Thailand and an entity they can trust.  Clients have the peace of mind knowing, that if they ever a problem or complaint, they are able to take it up directly with the DBD. This makes us the perfect risk-free choice for anyone who wants to make sure they get the real value from a service they paid for. This level of concern and care for our clients is unmatched by any other Private Investigation provider in Thailand. 

Have Concerns Over Your Partner?

We understand that it’s a difficult time when you have concerns over your partner. People often think maybe they are imagining it or over reacting? Or maybe some things just don’t add up and your fears are justified. Look we’re not here to judge anybody, and if you have questions or concerns about your partner, it’s best to get those concerns answered now, so you can hopefully move forward building a life together. Our job is not to judge and it’s not something to be embarrassed about, we’re here to discreetly find out the hard facts and present them to you confidentially.

We understand the sensitivity around this subject and what you must be going through right now is difficult and you may be doubting yourself when you’re about to hire a private investigator. While there is no shame in any of this, in order to have a strong relationship moving forward, you need to be able to trust your partner, so you need these questions answered. Hopefully we find out your partner is not cheating, but we will find out the truth.

We understand the concerns of men and women in these cases are very different and we are sensitive to it. 

For women, the risk is you give the best years of your life, body, mind and soul to this person, raise his children, support him through everything, only to find out this commitment wasn’t returned. You find out he has a secret girlfriend, but you find out years and years too late. How would you feel?

For men, the concerns are similar, but often in Thailand the man is the provider, you commit your life to this woman, you commit your assets, your future assets to this person and more. You have concerns now, but you don’t know if you should follow up and find out the truth, you possibly feel a little bit guilty even for questioning? Maybe you are dreading finding out the truth as you love her? However, which is worse, paying to find out the truth now? Or risk paying for a DNA test down the line?

In either case for men or women, the best course of action is to find out the truth now, rather than risking so much more down the line. We hope to find nothing, that your partner is faithful, and you can move forward guilt and worry free, building a much stronger and happier relationship together, but it starts with the truth.

Infidelity / Cheating Surveillance

Infidelity private investigation in Thailand is one of our most popular services.  Unfortunately sometimes partners lie, sometimes its “white lies” and sometimes it’s bigger ones, the more a person has to lose, the more they may lie to protect it. Sometimes they lie for unselfish reasons (to protect a lifestyle a partner can offer for the sake of a secret child) or sometimes it is for selfish reasons. Whatever it may be, Actio’s experts in romantic partner investigation will uncover truth.

In order to be able to properly relax and be comfortable in your relationship and build a life together, you need to know the truth, hopefully we can give you that peace of mind and show you your partner was faithful. If we can’t do that, and it turns out they are not faithful, do you think it is better to find out now? Or ten years too late? It’s a question of, the cost of hiring a private investigator now, verses risking the cost of the best years of your life, or most of your assets in a messy divorce? Or even worse, needing a DNA test on what you thought was your 8 year old son?

These are indeed harsh examples, but they are included because they are real life examples we have seen. We will save you the risk of this pain later, by finding out the truth now. Our discreet monitoring service means your partner will never be aware, and no matter where they go, we will be able to follow. We will be your eyes and ears on the ground, and you will have all the answers you deserve.

Pre-Marriage Checks

If you are about to go in to business with someone, you should do your due diligence right? Well with even higher stakes when entering a marriage in Thailand, why would you not do the same? If for nothing else to have peace of mind knowing that you can trust your spouse to be.  If you get the answers you want, and you know you can trust them when you aren’t around, you will have a stronger marriage as a result.  Our pre marriage checks involve us providing the most discreet monitoring and surveillance service available in Thailand. We use state of the art equipment and tactics to make sure we provide the most in thorough private investigation possible, without the target ever becoming aware.

Asset Search

Thailand is a huge country with a large population, its easy to hide assets where no one is looking. Business partners or spouses often lie about what assets they have for fear that they will lose them in a legal case or divorce. However, if you need to know what they have and what its worth is. They may be hiding wealth in a multitude of ways, a boat, 10 cars, maybe 2 extra homes or much more. We just don’t know until we investigate, but that is a lot of money that you may have full legal claim to, it may be rightfully yours and they are hiding it. We can carry out an asset search and find where these assets are hiding or if there is anything to be found. The cost of hiring a private investigator to find out the truth here, may be nothing compared to how much the truth is worth. 

Background Check

Before you go in to business with a company, person or even hire someone, you want to know if its a good fit right? We all do our due diligence here, but what about information that is not easy to come by? In order to make the correct decision, you need to have all the essential information, we will get that for you. 

You don’t have to take the risk of making a huge costly mistake by hiring the wrong person or going in to the wrong business partnership.

Our secret and discreet investigators will get you the answers you need without the person or business ever being alerted to our information gathering. 

The cost of a background check is small compared to the cost of doing business with the wrong person.
