How to Hire a Private Investigator in Singapore: What to Check Before You Commit in 2026
It is a legal, organised procedure to hire private investigators in Singapore, but the quality of each private investigation firm can differ. Verify licensing, relevant expertise, contractual responsibilities and confidentiality before you commit. At Baker Street Private Investigator, we help you understand your investigation needs before recommending a practical course of action.
What Does a Private Investigator in Singapore Do?
A private investigator Singapore is a trained and licensed person recognised by the Singapore Police Force to collect evidence, conduct surveillance or investigate personally or in business cases, as well as for legal counsel privately. Under the Private Security Industry Act, investigations are policed by the Police Licensing and Regulatory Department, or PLRD for short.
1. Why More People in Singapore Are Turning to Private Investigators
These investigators come to help you in tough situations, and the business in Singapore is quickly moving towards making this choice. If someone thinks their partner has been unfaithful, or if someone is looking for a private investigator to find missing persons. Corporations often hire professional investigators to disprove vendors, find improprieties, and act as an acquiring party.
Private investigation still encompasses a lot of surveillance. A discreet surveillance operation can establish movements, meetings and patterns without unnecessary confrontation. Your investigator must still work within Singapore law, respect legal boundaries and gather evidence in a form that may be useful to your solicitor or the Singapore courts.
The Three Situations That Drive Most Hire Decisions
A lot of personal cases might concern a cheating partner, marriage problems, or child custody uncertainty before marriage. Each case is different and thus needs the same discretion and professionalism. A reputable investigator will tell you what can or cannot be determined, but won’t make any promises other than being able to find the truth as fast as possible.
Commercial investigation, employee misconduct checks, fraud enquiries or vendor screening is commonly essential for businesses. A professional private team may examine records, conduct interviews and use covert observation when lawful. Legal teams may also require investigative services to trace witnesses, confirm facts and prepare documented material for investigation cases.
2. The Non-Negotiables When Hiring a Private Investigator in Singapore
SPF Licensing Is the Starting Point
The Singapore Police Force regulates the sector under the Private Security Industry Act. A licensed private investigation agency must hold a current licence issued through the regulatory department. Baker Street Private Investigator is licensed by the Singapore Police Force under licence L/PS/000395/2025.
You should request the agency’s licence number before signing an agreement. A licensed private investigator should have no issue providing this information. Police licensing is the baseline for any private detective agency claiming to offer private investigation services in Singapore.
Experience in Your Specific Case Type
A seasoned private investigator working on a matrimonial case approaches the task differently compared to an investigator specialising in corporate fraud. The importance of selecting a private investigator is that you recognise the specific sort of case, probable challenges and what evidence will be needed. General experience alone does not make an agency the best private investigator Singapore has for your particular circumstances.
We offer a range of services covering surveillance, matrimonial investigation, commercial investigation and legal support. Our experienced investigators first identify the category that suits your concern. This allows us to propose professional services that match the facts rather than forcing every client into the same package.
A Clear Scope and Written Agreement
Before private investigator hire arrangements begin, ask for a written scope, estimated timeframe and fee structure. A professional and efficient agency should explain how updates will be delivered, who manages the case and how information stays confidential. Avoid any PI agency that remains vague about costs, evidence handling or expected outcomes.
Good investigators do not guarantee results that depend on another person’s behaviour. A trusted private investigation agency gives you realistic expectations and protects confidentiality throughout the work. This provides peace of mind before resources are committed.
3. What a Private Investigator in Singapore Can Actually Do for You
Surveillance
Discreet surveillance may document a subject’s movements, meetings and daily activity. It is regularly used in matrimonial disputes and employee misconduct matters. Our team works discreetly, follows Singapore law and records relevant findings through a thorough investigation.
Matrimonial Investigation
Cases range from suspected adultery, premarital checks to discovering assets and evidence related to custody battles. A reliable investigator appreciates that these cases are very personal and extremely difficult to go through emotionally. We maintain confidentiality and communicate with you carefully throughout the case.
Commercial Investigation
A commercial investigation may address fraud, intellectual property concerns, employee misconduct and third-party verification. Professional private investigators can support your internal compliance process by checking facts that may not appear in ordinary records. A reliable private agency should present findings clearly without exaggerating what the evidence proves.
Legal Investigation
Legal investigations support solicitors, companies and individuals involved in disputes. Services can include witness tracing, fact verification and documented evidence collection. Experienced private investigator services should be planned with court requirements in mind, particularly when materials could later be presented before Singapore courts.
How Do I Verify a Private Investigator’s Licence in Singapore?
Request the PLRD licence number and check it against the official Singapore Police Force licensing information. Every licensed private investigation agency in Singapore must have a valid authorisation. A firm that refuses to provide its licence details should not be engaged.
Is Hiring a Private Detective Legal in Singapore?
The answer is yes, as long as you employ a licensed agency. The investigator cannot trespass, break into private accounts or pose as authorities; he or she must adhere to Singapore law. Evidence gathering is the key to making progress, and licensed investigators operate within clear legal boundaries here.
What Is the Difference Between a Private Investigator and a Private Detective?
Usually, the terms private investigator and private detective are used interchangeably. Both refer to professionals who research personal, legal or business matters for their clients. Also include terms: detective agency, private investigator agency, or private investigation agency in Singapore.
How Much Does It Cost to Hire a Private Investigator in Singapore?
Costs depend on the investigation type, duration, staffing and operational requirements. When you need a PI, ask for a written proposal rather than accepting an unclear verbal estimate. A leading private agency will explain what is included and whether additional work requires your approval.
Use of words like best private investigators, leading private investigator or hire top private investigators when hiring private detectives. Review the licence; see for background experience, and then reporting roles and written terms. Baker Street Private Investigator aims to provide trusted private investigation support across Singapore, giving you a clear route to get the truth and make informed decisions.
