It’s widely misunderstood that private investigators are hired only for one spouse to find out what their partner is up to. While this may be the case for some, there are many other reasons why private investigators are hired. Whatever the purpose, hiring the best private investigator in Singapore can unearth some truths that you may not have known before.

For a start, it’s important to note that a private investigator needs to be licensed by the Singapore Police Force. Even after undergoing private investigator training, they’re still required to undergo a series of rigorous tests to be legally recognised as a private investigator in Singapore.

What can a private investigator in Singapore do for you?

1. Maid surveillance

Maid surveillance is one of the services that private investigators can carry out. Some employers may have suspicions that their maids are engaging in activity that may be concerning. 

As such, they may hire private investigators to keep tabs on their maids on their off days. 

2. Employee surveillance

Private investigators are also able to monitor the activity of employees. Some common techniques include tracking phone records during working hours, obtaining video footage through surveillance cameras, installing monitoring software in an employee’s computer, and performing undercover surveillance. 

3. Spousal surveillance

Private investigators use various methods for this, one of which involves fixed surveillance (also known as “stakeout”). This means that they observe people and areas from a distance without being noticed. 

Another method could be stationary technical surveillance, where a hidden camera and recording equipment is installed in a parked car. This is sometimes referred to as unmanned surveillance. 

4. Children surveillance

With unhealthy content being easily accessible these days, you may be concerned about your children’s online activity and social life. 

Private investigators can assist in monitoring your children’s online presence and behaviour. This could be done by installing tracking software that can download emails, text messages, and web history within devices. 

Such software can also allow parents to view children’s real-time social activities, geographic location, as well as online purchases.

5. Finding missing persons 

Private investigators can also help you locate missing persons. However, note that you’ll need to communicate to the private investigator why the person could have gone missing. 

Did the missing person have tensions with the family? Did he have any unresolved financial responsibilities? Are there reasons to show that the missing person did not want to be located?

6. Gambling-related movements of family members

Gambling affects more than just the life of the gambler himself/herself. Perhaps you’re worried about a family member’s gambling habits turning into an addiction, and would like to intervene before it turns severe. 

The first step is to be better aware of the gambler’s habits and activities, which a private investigator can help with. 

7. Trademark or copyright infringement matters

If you suspect that another company is involved in illegal trademark or copyright infringement, you can hire a private investigator to investigate the situation. 

While there are some limitations as to how far a private investigator can investigate a company, they might still be able to find sufficient evidence for your case. 

Do enquire with individual private investigation companies to have a better understanding of what exactly they can do for you.

8. Investigations to obtain evidence for use in civil or criminal matters

Professional private investigators in Singapore can also be hired to source information for legal cases. 

For example, they can conduct surveillance to acquire evidence for criminal cases and trial preparation. For civil matters, the scope of cases can include motor vehicle accidents, workplace accidents, and wrongful loss of life.
