Each one answers a question we are asked repeatedly on the phone.

Choosing an agency

What a detective agency actually costs in India — a 2026 guide

Matrimonial

Pre-matrimonial background check — the complete checklist

A practical pre matrimonial verification checklist for Indian families: what you can check yourself, what needs an investigator, and the red flags.

Matrimonial

How to verify a matrimonial match in India, step by step

Choosing an agency

Detective agencies in Jaipur: how to compare them properly

How to compare detective agencies in Jaipur: the five checks that separate a real agency from a website, the questions to ask, and the promises to refuse.

Surveillance

How private surveillance actually works — and what it can realistically produce

What surveillance by a private investigator in India involves — how field days are planned, what is documented, and what the evidence can prove.

Corporate

Corporate fraud warning signs — what internal loss actually looks like

The four patterns behind most internal fraud in Indian SMEs, the warning signs that precede them, and how to investigate without tipping anyone off.

Verification

Background verification red flags that employers consistently miss

The discrepancies that matter most in Indian pre-employment screening, why document checks miss them, and how to design a process that actually works.

Working with us

Confidentiality in a private investigation — what it should actually mean

What confidentiality really means when you hire a private investigator in India: data handling, contact protocols and discretion in the field.

Asset verification

Asset verification — why records and reality diverge in India

How property verification works in India, the three gaps that cause most losses, and why a physical inspection is non-negotiable before money moves.

Matrimonial

Post-matrimonial investigation — a practical guide before you commission one

When a post matrimonial investigation is appropriate, what it can and cannot establish, and how the evidence is actually used in Indian matrimonial proceedings.

Where to start

If a marriage is being arranged, read the pre-matrimonial checklist first and the guide to verifying a match second; between them they cover what families most often fail to check. If you suspect something is wrong inside a marriage, the post-matrimonial guide sets out what can lawfully be established and what cannot.

Business owners usually start with the corporate fraud warning signs, then the background-verification red flags for hiring. Anyone comparing agencies should read what a detective agency costs and how to choose one before paying a deposit to anybody.

Reading from outside India? Most of these guides apply unchanged — the difference is how a case is run from abroad, which is covered on our page for clients outside India and, for a match living abroad, on NRI marriage investigation.
