What does a private investigator in Singapore do?

A licensed private investigator gathers facts lawfully — through discreet surveillance in public places, searches of official records such as ACRA, interviews and technical sweeps — and turns them into documented evidence you can rely on for personal decisions, court proceedings or corporate action.

Signals

When do you need a private investigator in Singapore?

Usually before you’re sure. These are the moments people most often call us.

  • Their story keeps changing. Inconsistent explanations, new routines, a locked phone.
  • Numbers don’t add up. Stock losses, odd vendor invoices, unexplained claims.
  • You’re about to commit. A marriage, a hire, a partner, an investment.
  • You feel watched. Someone knows what was said in private — or where you’ve been.
  • You’re heading to court. You need a witness, an address, or proof of assets.
  • A child’s wellbeing is in question. Custody, access, a caregiver or worrying company.

Our process

How a Ranger investigation works

Clear, lawful and paced to your needs — you’ll always know what happens next.

  1. Free consultation

    A confidential conversation — at our Lavender office, by phone or WhatsApp — to understand what you need to know.

  2. Case assessment

    We test feasibility and legality, then propose a strategy, timeline and clear quotation.

  3. Investigation

    Licensed investigators work discreetly using proven field craft and modern tools, with updates where appropriate.

  4. Evidence delivery

    A structured report with time-stamped photos, video or records — and advice on your next step.

Within the law

What a licensed PI in Singapore can — and can’t — do

Evidence only helps you if it was gathered lawfully. Here’s where we draw the line.

What we do

  • Surveillance in public or legally accessible places
  • Time-stamped photo & video documentation
  • Searches of lawful public & official records (ACRA, court, property)
  • Interviews with willing witnesses
  • Bug sweeps with the owner’s or occupant’s consent
  • Court-ready reports and witness support

What we will never do

  • Hack phones, email or social media accounts
  • Obtain bank or telco records without legal authority
  • Trespass or enter private property
  • Plant trackers on vehicles you don’t own
  • Impersonate police or public officers
  • Harass, threaten or entrap anyone

FAQ

Common questions about private investigators in Singapore

More FAQs
Is it legal to hire a private investigator in Singapore?

Yes. It is legal to engage a private investigation agency licensed by the Singapore Police Force under the Private Security Industry Act. Ranger holds Private Investigation Agency Licence L/PS/000759/2025. Always ask to see an agency’s licence before you engage it.

How much does a private investigator cost in Singapore?

Pricing depends on scope, complexity, manpower, urgency, duration, locations and reporting needs. A surveillance case needing two investigators over several evenings costs more than a desk-based background check. After a free, confidential consultation we give you a clear quotation before any work begins.

What can a private investigator legally do in Singapore?

A licensed PI can conduct surveillance in public or legally accessible places, take time-stamped photos and video, search lawful public and official records (such as ACRA), interview willing witnesses, locate people and assets, and prepare evidence reports. PIs cannot hack phones or accounts, trespass, impersonate police, or access private bank or telco records without legal authority.

Do I need proof before contacting a private investigator?

No. Most clients come to us with concerns, inconsistencies or incomplete information — not proof. Finding out what is actually happening is our job.

How long does a private investigation take?

It depends on the matter. Some cases can be scoped and acted on within days; others need repeated observation windows, multiple locations or careful verification. Corporate due diligence typically takes 5–10 working days. We give you a realistic timeline at the start.

Can a private investigator’s evidence be used in court in Singapore?

Potentially, yes — if it was gathered lawfully and documented properly. Our reports and time-stamped evidence are prepared with lawyers, the Family Justice Courts and HR panels in mind, and our investigators can support your legal team where needed.

Can a private investigator guarantee results?

No responsible professional should guarantee an outcome. What we guarantee is a lawful, disciplined and honest process — and a clear account of what we found, including when the answer is that nothing untoward is happening.

Do you handle investigations outside Singapore?

Yes. We run cross-border cases — especially Malaysia and the wider region — through vetted, licensed partner agencies, with one point of contact and unified reporting from Ranger.
