Cohabitation Investigations in Las Vegas: How a Private Investigator Documents the Truth Author David J., March 18, 2026March 18, 2026 As a private investigator in Las Vegas, Nevada, I am frequently retained to conduct cohabitation investigations in support of family law matters throughout Clark County, including Henderson and Summerlin.These cases often begin with a simple concern: someone believes an ex-spouse or partner may be living with another person while representing otherwise. From an investigative standpoint, however, the issue is not suspicion. The question is whether the situation can be documented with consistent, verifiable evidence. What Is a Cohabitation Investigation? A cohabitation investigation is the process of determining whether two individuals are living together in a shared, domestic arrangement.This involves examining:Living patterns and residence activityDaily routines and movementLifestyle indicatorsPublic and observable behaviorIn many ways, these investigations are handled similarly to fraud-related matters. Statements are compared against real-world activity to determine whether they align. Why Cohabitation Investigations Matter Cohabitation investigations in Las Vegas are commonly conducted in matters involving:Spousal support (alimony) concernsChild support-related disputesDivorce and post-decree mattersIn a city like Las Vegas, where people frequently relocate, share residences, or maintain flexible living arrangements, accurately documenting where someone actually lives becomes critical.The purpose of the investigation is not to draw legal conclusions, but to gather and document facts for review by attorneys and the court.
