Key Consideration Factors

• License and Certification: The first thing to consider when selecting a private investigator is whether they are licensed and certified by the relevant authorities in Singapore. A licensed private investigator has undergone training and has the necessary skills and knowledge to carry out investigations legally and ethically.
• Experience: The experience of a private investigator is another important factor to consider. Look for investigators who have experience with cases similar to yours, as this can give you greater confidence in their ability to handle your court case effectively.
• Reputation: Consider the reputation of the private investigator before hiring them. Look for reviews or testimonials from past clients, as well as any awards or recognition they may have received.
• Specialization: Private investigators may specialize in certain areas such as surveillance, background checks, or fraud investigation. Consider what type of investigation you need and look for an investigator with specialized expertise in that area.
• Technology and Equipment: Technology plays an important role in modern-day investigations, so it’s important to look for investigators who have access to advanced technology and equipment that can aid in their work.
• Communication Skills: Good communication is essential when working with a private investigator. Look for someone who communicates clearly, keeps you updated on progress regularly, and takes time to explain any complex legal or technical issues related to your court case.
• Cost: Finally, consider the cost of hiring a private investigator before making a decision. While price shouldn’t be the only factor influencing your decision, it’s important to find an investigator whose fees fit within your budget.

IIS’ professionalism helped crack the case within a short period of time and justice was served.
