Let's be honest — nobody wakes up one morning and decides they want to hire a detective. Something happens. A feeling that won't go away. A suspicion you can't shake. Or a situation that has quietly gotten out of hand. That's usually when people start searching for a private detective agency in Delhi.
If that's where you are right now, you're not alone — and you've come to the right place.
CircleBiz has been working with people across Delhi for over 23 years. We've handled more than 15,000 cases—matrimonial disputes, corporate fraud, missing persons, background checks, and everything in between. We're not a call center with a fancy website. We're a team of real investigators based out of Dwarka, Delhi, who take your privacy seriously and actually get results.
People come to us with all kinds of situations. Some are deeply personal. Others are purely professional. Here's what we deal with on a regular basis:
Matrimonial Investigations
This is a big part of what we do. Families in Delhi often reach out to us before or after a marriage to verify a person's background, check if they've been honest about their job or finances, or confirm whether a spouse is being faithful. These aren't easy conversations to have, but they're important ones—and we handle them without judgment.
Whether it's a pre-matrimonial background check before the wedding or a post-matrimonial investigation because something feels off, we approach every case with sensitivity. We know these situations affect families deeply, and we treat them accordingly.
Divorce and Custody Cases
If you're going through a legal separation and need evidence — whether for the court, your lawyer, or your own clarity — we can help. We document what we find properly, so it can actually be used when it matters.
Corporate and Business Investigations
Companies in Delhi NCR hire us when they suspect internal theft, fraud, or employee misconduct or when they need to verify a business partner before signing a major deal. We also help HR teams with pre-employment background screening.
Missing Person Tracing
If a family member has gone missing or someone has simply disappeared without explanation, we use field investigation and other methods to trace them across Delhi, NCR, and other parts of India.
Loyalty Testing
Some clients want to know if their partner is being faithful before they take a big step — or because they've started noticing signs they can't ignore. We handle this confidentially, and we give you straight answers.
Personal Background Checks
Sometimes you just need to know more about someone — a new business partner, a domestic worker, someone your son or daughter is seeing. We run thorough checks and give you a clear picture.
Our investigators are active across all parts of Delhi and the wider NCR. We cover South Delhi areas like Saket, Hauz Khas, Greater Kailash, Lajpat Nagar, and Vasant Kunj. In West Delhi, we regularly work in Dwarka, Janakpuri, Rajouri Garden, and Paschim Vihar. North Delhi includes Rohini, Pitampura, Model Town, and Shalimar Bagh. East Delhi areas like Preet Vihar, Mayur Vihar, and Laxmi Nagar are also well within our coverage.
Outside Delhi, we serve Gurgaon, Noida, Faridabad, and Ghaziabad regularly. And for cases that go beyond NCR, we have investigators in 90+ cities across India. We've also handled cases for clients based in Dubai, the USA, Nepal, and Mauritius.
We don't believe in overcomplicating things. When you call us, the first thing we do is listen. You tell us what's going on, we ask a few questions to understand the situation better, and then we suggest the most practical approach.
Once you're comfortable moving forward, our team takes over. We conduct physical surveillance, digital research, field verification, or whichever combination is appropriate for your case. Throughout the process, we keep you updated — you're never left wondering what's happening.
At the end, you get a clear, documented report. If you need it for legal proceedings, we make sure it's structured in a way your lawyer can use.
Step 1 — Call +91-7669484555 or drop us a message. Tell us what's happening.
Step 2 — We have a free, private consultation. No commitment required.
Step 3 — If you want to proceed, we put together a plan and get to work.
Yes, completely. A private detective agency in Delhi operates within the legal boundaries set by Indian law. We don't tap phones illegally, we don't break into accounts, and we don't do anything that could get you into trouble later. Every piece of evidence we gather is obtained legally, which also means it holds up in court if you need it to.
We're not going to fill this section with generic lines about being "professional" and "trusted." Instead, here's what our clients actually say matters to them:
We pick up the phone. A lot of detective agencies in Delhi are difficult to reach after you've paid. We stay accessible through the entire case.
We don't judge. People come to us in vulnerable situations. We've seen it all, and our job is to help — not to form opinions about your personal life.
We've been doing this for 23 years. That's not just a number. It means we've dealt with complex, unusual, and difficult cases that newer agencies wouldn't know how to handle.
We're honest about what we can and can't do. If a case isn't something we can help with, we'll tell you upfront rather than taking your money.
Our office is in Dwarka, Delhi. We're local, we're reachable, and we actually know this city.
How much will it cost? It depends on the type of investigation, how long it takes, and what's involved. We give you a clear estimate upfront. There are no surprise charges midway through.
How long will it take? A background check can be done in a few days. A full matrimonial or surveillance case might take one to three weeks. We give you a realistic timeline from the start.
Will anyone find out I contacted you? No. We keep all client information completely private. The person you're investigating will not know you approached us.
Can your evidence be used in court? Yes. We specifically document findings in a way that meets legal standards so you can use them in divorce cases, custody hearings, or fraud cases.
If something is bothering you and you need answers, the worst thing you can do is sit on it. Most of our clients tell us they wish they'd called sooner.
Reach out to us today. The first conversation is completely free and confidential.
