[ CLIENTS FEEDBACK ]
Verified Client Success Stories & Testimonials
We were about to hire a new executive, but something in his work history didn't quite line up. We hired SDA to do a thorough background and pre-employment check just to be safe. Turns out, the candidate had completely fabricated his last two roles and had a history of workplace misconduct. The team provided a detailed, verified report that saved us from making a very expensive and damaging mistake.
When my younger brother cut off contact and disappeared, local authorities could only do so much. We were absolutely desperate. The investigators at Spy Detective Agency were so compassionate and worked relentlessly on our case. Within just a few weeks, they tracked him down safely in another city. Words can't describe how grateful our family is for their dedication.
I spent months feeling like I was going crazy, suspecting my wife was cheating but having zero proof. SDA handled my situation with so much sensitivity and respect. They gathered the photographic evidence I needed without him ever suspecting they were there. It was painful to see the truth, but I finally have the closure and legal proof I need to move on with my life
I was extremely anxious about my daughter's upcoming marriage because something just felt a bit 'off' about the groom's background. A family friend recommended Spy Detective Agency. The team was incredibly discreet and empathetic to my worries. Within a week, they provided a detailed background report that actually cleared up our doubts and verified his credentials. It gave our family such immense peace of mind. I highly recommend them to any parent wanting to be absolutely sure.
Running a mid-sized logistics company, I started suspecting that a senior employee was leaking confidential client data to a competitor. I reached out to SDA, and their professionalism blew me away. They handled the corporate investigation quietly without causing any panic in the office, and gathered solid, actionable evidence we could actually use legally. Thank you for saving our company from a potential disaster!"
During a very messy and stressful legal dispute, I had this lingering, paranoid feeling that my home office was being monitored. I called them for a bug sweep, and their technical experts arrived within hours. They were incredibly thorough and walked me through exactly what they were scanning. They actually found a hidden audio device I would have never spotted on my own. I finally feel safe in my own house again.
Going through a rough separation is hard enough, but trying to prove my ex was hiding money during our divorce settlement was an absolute nightmare. The team at Spy Detective Agency stepped in and did what I couldn't do alone. Their asset verification report was comprehensive, legally sound, and ultimately helped me get a fair settlement in court. They kept everything 100% confidential and respected my boundaries during a really tough time.

How Long Does a Pre- or Post-Matrimonial Investigation Take in Delhi?
The duration of a matrimonial investigation depends on the purpose of the case and the data to be checked. Pre pre-matrimonial investigation normally takes a few days to few weeks and in complex cases it could take more time.
A matrimonial detective agency usually investigates educational qualifications, employment details, family background, financial status, social behaviour, lifestyle pattern and other relevant information. If surveillance is required, the duration of it will depend on the subject’s activities and habits.
Concerns of financial concealment or behaviour after matrimonial investigations into suspected infidelity may influence the length of enquiry. The Detective Agency in Delhi usually looks into the scope of the case before starting the investigation and gives a tentative time frame.
The goal is not only to get the investigation done quickly but to provide reliable, documented facts that allow clients to make educated decisions about their relationships and future commitments.
Can a Detective Agency Verify Employment History and Background Details in Delhi?
Yes, Employment verification is one of the most common services that a professional Detective Agency in Delhi provides. This process is used to verify the accuracy and consistency of a person’s employment history claimed with the records and findings.
These can include previous employee investigation, job titles, duration of work, educational qualifications, professional references and career history. Such employee verification services can help companies reduce recruitment risks and feel confident in their hiring.
In the context of a matrimonial, employment verification can also be useful for families who want to check claims regarding the career before marriage. Misrepresentation of professional qualifications or employment status can have serious personal and financial consequences.
These checks are carried out professionally and discreetly by a qualified private investigator in Delhi, maintaining confidentiality. We provide accurate employment verification to help our clients make informed decisions when it comes to hiring, partnerships and even marriage, so they can avoid potential risks that could come from inaccurate or misleading information.
What Information Is Checked During a Background Verification in Delhi?
Our background check services in Delhi are tailored to purpose—matrimonial, employment, tenancy, or executive hiring. Common checks include:
- Identity and address validation
- Employment history and role verification (with HR consent or documented sources)
- Education and certifications (directly with institutions when possible)
- Criminal and civil litigation searches in relevant jurisdictions
- Financial stress indicators (public records), asset verification when authorised
- Social media and digital footprint review (OSINT)
- Reference interviews (with consent)
Being a leading investigation agency in Delhi, we follow DPDP 2023 guidelines, obtain consent wherever required, and refrain from dealing with restricted information (such as CDRs of phones). For businesses, we follow human resource policies and keep an audit trail. You will get a comprehensive report supported by facts and risk ratings to take well-informed decisions.
Are Investigations Kept Confidential? How Do You Protect My Privacy?
Absolutely. Confidentiality is central to our work as a Detective Agency in Delhi. We implement:
- NDAs with clients and staff
- Need-to-know access to case data
- Encrypted storage and secure communication channels
- Code names for parties in internal logs
- Clean phone and vehicle protocols to prevent exposure during surveillance
- Discreet billing descriptors when requested
We also design field plans to minimise contact risks—rotating operatives across Delhi NCR and nearby sectors to avoid recognition. For corporates, we mirror your confidentiality and IT security standards. Processing of personal data follows DPDP 2023, while the case file is archived or destroyed depending on the terms of the contract. It is only the evidence relevant to your goals that will be recorded, while you decide who else receives the report (such as your lawyer).
Can Evidence Collected by a Detective Agency Be Used in Court?
Yes—if it’s lawfully obtained and properly documented. Courts may accept photographs, videos from public spaces, witness statements, open-source findings, and consent-based digital forensics. We maintain a chain of custody for digital files, time-stamp evidence, and, when needed, provide a Section 65B certificate for electronic records. A Detective Agency in Delhi cannot procure illegal items like phone call records or conduct unlawful recordings in private spaces; such material can harm your case. In conjunction with your attorney, we design our approach to gathering evidence based on where the evidence will be presented — civil, criminal, family, or disciplinary cases. We aim to provide you with sound and confirmed evidence that can hold up to any inspection. Please request samples of redacted reports from us before we start working.
Do You Provide Corporate Investigation Services in Delhi?
Yes. Corporate Investigation Services in Delhi. Our corporate investigation services in Delhi help businesses to detect fraud, verify critical information, reduce operational risks and safeguard confidential business interests. We offer discreet, professional and results-focused investigatory support tailored to individual business needs from start-ups and SMEs to large corporates and multinational organisations.

Delhi is the capital city of India and also a major commercial and business centre, where various organisations are involved in the fields of technology, finance, manufacturing, and government contracts, among others. In light of new business challenges and increased competition, organisations require accurate intelligence for the protection and control of any possible threat to their activities.
Our corporate investigation services allow businesses to gain verified information about possible risks and threats and to undertake investigations in order to preserve their reputation.
What Areas of Delhi NCR Do Your Investigators Cover?
The Spy Detective Agency offers investigation services in all major areas of Delhi such as Central Delhi, New Delhi, South Delhi, West Delhi, North Delhi and East Delhi. Our investigators work in the main residential, commercial and business districts on a regular basis, where personal, matrimonial and corporate investigations are frequently required.
Our investigators are often active in commercial areas such as Connaught Place and Karol Bagh, diplomatic and institutional areas such as Chanakyapuri, residential localities such as Greater Kailash, Vasant Kunj, Saket, Janakpuri, Rohini, Model Town, Preet Vihar and Mayur Vihar and busy retail and business centres such as Lajpat Nagar, Rajouri Garden and Chandni Chowk.
Delhi’s complex terrain of diplomatic enclaves, corporate hubs, residential colonies and commercial markets often demands good local knowledge and careful planning. Our investigators routinely work in these different environments, allowing us to adjust the investigative methods to the unique characteristics and constraints of each environment, while maintaining discretion and confidentiality.
We are a professional Detective Agency in Delhi and we understand that every investigation is different. In case your case is specific to a particular area in Delhi, our team can understand the needs and deploy investigators to help you achieve the investigation’s goals.
What Is a Loyalty Test Investigation and When Is It Needed?
The loyalty test investigation is an ethical process of observing behaviour without entrapping or forcing someone. Being a matrimonial detective agency, we conduct such investigations only under certain circumstances and where clients have issues with their partners. Usually, such investigations are done by monitoring the interactions based on opportunity (public interactions), confirming social trends and behavior, and recording reactions to situations. We do not manufacture any crimes, disguise ourselves as law enforcement officers, and violate any privacy rights of individuals. The objective of such an investigation is to get a clear idea about the situation and not to humiliate anyone. In the case of Delhi, such an investigation may include public observations (cafés, malls, social meetings), background verification, and social media monitoring. Before conducting an investigation, we will clearly inform you about our Investigation Agency in Delhi.
What Is a TSCM Bug Sweeping Service?
Technical Surveillance Counter Measures (TSCM), commonly referred to as bug sweeping, assist in the detection of hidden cameras, concealed microphones, GPS tracking units and other types of covert surveillance devices. These services are often required by companies, law firms, executives and individuals to safeguard sensitive discussions and information.
Our experts utilise specialised equipment, such as radio frequency (RF) scanners, spectrum analyzers and non-linear junction detectors (NLJDs) to find any possible surveillance threats. The results are presented to our clients in a comprehensive report.
What Should I Expect During My First Consultation with Spy Detective Agency?
Your first consultation will be conducted in confidence. We will have a conversation in which we will try to understand the issues, your objectives and the facts that are known. We will talk about the nature of the case, your questions and the time frame, practical considerations and the best way to investigate your problem.
Depending on the nature of the case, you can be asked very specific questions related to the location of the incident, schedules, persons involved, associates, business connections, automobiles and Internet usage or past events. The details help our investigators understand the context and what information can reasonably be verified.”
We are a trusted private investigation agency in Delhi and would describe the investigative techniques that may be appropriate for your objectives, including surveillance in open places, background verification, discreet field enquiries, intelligence gathering, cyber OSINT research or TSCM bug sweeping services, as appropriate.
Before we commence any investigation, we will set out the proposed scope of work, reporting process and expected deliverables so there is complete clarity on the assignment. If you decide to proceed, secure channels are opened and the investigation is commenced to the agreed objectives.
The clients are regularly informed on the progress of the investigation, but operational secrecy is maintained. Once complete you are provided with a structured report that contains verified findings, observations and supporting evidence where applicable. This helps you to make informed personal, legal or business decisions with confidence.
How Quickly Can an Investigation Begin in Delhi and How Long Does It Take?
The deployment process typically takes 24–48 hours after we know the parameters of your request. In case you need an immediate surveillance service, for example, in case of the Sector 18 meetings or late night activities, we can deploy on the same day. Timelines vary:
- Basic background checks: 2–7 working days
- Pre/post matrimonial: 7–21 days
- Corporate fraud probes: 2–8 weeks, depending on data access
- Cyber investigation: 5–20 working days
- TSCM sweeps: Scheduled within 1–5 days; same-day for emergencies
As a Detective Agency in Delhi, we plan around Metro timings, traffic bottlenecks (DND/Yamuna Expressway), and building entry protocols. You’ll get interim updates and a timeline if cross-city work is needed. We never rush at the expense of legality or quality.
How Can I Schedule a Free, Confidential Consultation with Spy Detective Agency?
The first step is often the very difficult, but you don’t have to tackle sensitive issues alone. Have a confidential discussion of your situation directly with an experienced case director. We hear your concerns, understand your goals, discuss possible investigation strategies, and offer honest guidance, not pressure to proceed.
- Complete Privacy & Discretion: Your privacy is our concern. Information about consultations and cases is managed securely and confidentially.
- No-Obligation Guidance: Know the recommended approach, expected process and transparent cost considerations before making any decision.
- Personalised Case Support: Your case is handled personally to ensure clear communication and consistent case management throughout the investigation.
- 18+ Years of Experience: We offer decades of investigative experience, professional field expertise and well-documented findings to you across Delhi NCR.
