Matrimonial Infidelity:

Cheating Spouse and Matrimonial Investigations

When you contact this agency for a consultation, your case and information will remain confidential. Our agency's  infidelity and cheating spouse or partner investigators are sensitive to your needs and emotions of this type of investigation. Don't make the mistake of trying to "do it yourself." Let Long Island Investigations find the truth!

We are a fully insured, licensed and bonded Private Investigator, licensed by New York State, with well trained and experienced investigators.

Matrimonial Infidelity and cheating partners are, as we know, incredibly devastating to you. At Long Island Investigations we take pride in providing you with personal attention. We understand the sensitive and delicate nature of infidelity, and are aware of your concerns in finding out the truth.

Our investigators will perform surveillance of the suspected  cheating party and observe and document their movements. If any inappropriate meetings take place such as observing them holding hands, kissing, entering a motel or residence, or showing some type of affection beyond casual friendship, this will be documented with video or photos when possible, along with a detailed report including all facts, and prepared in the proper format for court.

We can also perform a background search on the party involved with your partner, to learn more and identify that person.

Cheating spouse or infidelity cases are very sensitive and personal. We at Long Island Investigations are aware of your special needs and the sensitivity of these issues. We will conduct these cases discreetly and professionally and gather evidence while keeping you updated throughout the investigation.

When you need the best, Experience is our strength!
