Infidelity Investigation: What You Need to Know
Private Investigator Manhattan helps you request an introduction for an infidelity investigation. We do not conduct the investigation. You decide whether to engage an independent provider after discussing your question, the proposed methods, and a written quote.
A change in a partner’s behavior is not proof of an affair. Define what you need to establish and what decision the answer would support. If the purpose is a divorce or custody case, ask your attorney whether the proposed research is relevant before paying for surveillance.
An investigator may propose lawful observation and records research, with a report of what they observed and any gaps. Staffing and timing depend on the assignment. No provider can guarantee evidence of infidelity, undetected surveillance, or a court outcome.
Benefits of Infidelity Investigation
A defined question
Discuss the uncertainty you need resolved and whether the proposed work can address it within your budget.
A written scope
Agree on methods, hours, staffing, permitted expenses, and approval before additional work.
Factual reporting
Ask for dated observations, available media, and clear separation between what was seen and what was inferred.
Attorney coordination
If litigation is involved, agree how the investigator and your attorney will communicate and handle records.

Do You Need Infidelity Investigation?
An initial discussion may help you assess work such as:
- Documenting activity relevant to a specific relationship question through lawful observation.
- Clarifying a factual issue that your matrimonial attorney has identified.
- Assessing whether a records-based inquiry would be more useful than surveillance.
- Planning a limited first phase with a clear budget and review point.
Use an initial discussion to decide whether the proposed work can answer your question. Ask the investigator for written terms before authorizing any charges.
How the Process Works
Describe your question
Provide the case type, Manhattan locations, relevant timing, and preferred contact method. Keep the initial inquiry brief.
Discuss provider fit
Before engaging anyone, ask about their New York license, relevant experience, staffing, insurance, and availability.
Agree on the work
Review the written scope, price, cancellation terms, reporting arrangements, and approval limit. An introduction does not start an investigation.
Review the findings
Compare the report with the agreed question. Discuss inconclusive results and any proposed extension before authorizing further work.
Agree on the deliverables
Ask a prospective investigator to put the following in the engagement terms. Availability depends on the assignment; findings and court admissibility cannot be guaranteed.
- A dated account of observations, including periods when no relevant activity was observed.
- Photos or video where lawfully obtained, with context and any gaps explained.
- An agreed update schedule and a report separating observations from conclusions.
What affects the cost?
The proposed observation windows, minimum booking, number of investigators, travel, waiting time and report preparation determine the quote. Ask whether an hourly rate is per investigator or for the whole team, and set a limit before approving more time.
This matching service does not set investigation rates. Ask how a retainer is applied, how unused funds are handled, and whether expenses and applicable tax are included. Use our quote-comparison checklist and researched Manhattan pricing examples.
If divorce or custody proceedings are involved, ask your attorney which facts matter before commissioning surveillance. See our infidelity hiring guide and New York legal limits. An investigator cannot promise a particular divorce or custody outcome.
