In a city as vibrant and fast-paced as New York, trust can be both precious and fragile. Relationships are built on it — and when that trust begins to erode, uncertainty and anxiety can quickly take over. If you suspect that your partner or spouse may be unfaithful, getting to the truth is painful but essential. That’s where New York Investigations, led by David Schassler, comes in — offering professional, discreet, and compassionate infidelity investigation services in NYC.
As one of New York’s most respected private investigation firms, New York Investigations specializes in cheating spouse and infidelity cases, helping clients find clarity when doubt takes hold. Using state-of-the-art surveillance techniques, investigative expertise, and complete confidentiality, David Schassler and his team uncover the facts — so you can make informed decisions about your future.
An infidelity investigator — sometimes called a cheating spouse investigator — is a licensed professional trained to discreetly observe, document, and verify a partner’s activities when suspicions of infidelity arise. Unlike speculation or emotional confrontation, an investigator relies on factual evidence — including photos, videos, and digital records — to reveal the truth.
In a complex city like New York, with its constant movement, anonymity, and digital communication, proving or disproving infidelity requires expertise, patience, and precision. David Schassler and New York Investigations specialize in conducting these investigations legally, confidentially, and efficiently.
Privacy and legality are crucial in every investigation. In New York, it’s illegal to trespass, wiretap, or invade private communications without consent. David Schassler ensures every operation is 100% compliant with state and federal laws — protecting both the client and the integrity of the evidence.
Because New York Investigations operates under full state licensure, all evidence gathered is admissible in court, should you need it for divorce proceedings, custody cases, or legal settlements.
While no single behavior proves infidelity, certain patterns often raise concern. New York Investigations frequently assists clients who notice sudden, unexplained changes in their partner’s behavior.
Common warning signs include:
Unusual phone secrecy — deleting texts or changing passwords suddenly
Unexplained absences or late nights at work
Diminished intimacy or affection
Defensive or evasive answers when questioned
New spending habits or credit card charges
Sudden concern about appearance or new wardrobe choices
Frequent “business trips” or unexplained outings
Increased time on social media or encrypted messaging apps
If multiple signs appear over time, it may be wise to seek professional help. An infidelity investigator in NYC, like David Schassler, can provide clarity — and that clarity can bring emotional peace and legal protection.

Here’s an overview of the typical process:
It begins with a private, judgment-free consultation with David Schassler. You’ll discuss your suspicions, relationship background, and the specific behavior that raised concerns. All communication is strictly confidential, and you are never obligated to proceed unless you feel comfortable.
After understanding your situation, Schassler designs a custom surveillance plan. This may include physical observation, digital monitoring, or a combination of investigative methods. The strategy is tailored to your partner’s schedule, habits, and potential risk factors.
The investigation may involve discreet physical surveillance, vehicle tracking (where legally permitted), or documenting meetings and activities. Investigators use:
High-definition cameras and video recorders
GPS tracking systems (legal use only)
Covert observation techniques
Digital footprint analysis
All evidence — including photos, timestamps, and logs — is collected within the boundaries of New York law.
After completing the surveillance phase, New York Investigations compiles a detailed report that may include:
Verified timelines of activities
Locations visited and individuals met
Photos or video documentation
Expert analysis of behavioral patterns
This report can provide peace of mind or serve as crucial legal evidence during divorce or custody proceedings.
Infidelity investigations often come with emotional and legal consequences. David Schassler and his team don’t just deliver facts — they provide guidance on next steps, including potential legal referrals, counseling, or mediation resources.
In the digital era, infidelity often leaves both physical and electronic trails. New York Investigations integrates traditional surveillance with advanced investigative tools to ensure comprehensive results.

As David Schassler often tells clients:
