A relationship investigation is a private investigation service focused on verifying the nature, behavior, or status of a personal relationship. Investigators may document whether a subject is involved in an undisclosed romantic relationship, confirm cohabitation with a new partner, or gather behavioral evidence relevant to family law proceedings, divorce cases, or custody disputes.
In plain terms, a relationship investigation involves hiring a licensed investigator to find out factual information about what someone is doing in their personal life, typically a spouse, partner, or co-parent. This might mean confirming whether a person is seeing someone new, living with a partner, or behaving in ways that conflict with what they have claimed. The investigator collects observable, documented evidence rather than rumors or suspicions.
A spouse going through a divorce may need to document that their former partner is cohabiting with a new romantic partner, which can affect alimony or spousal support calculations under certain state laws. A parent involved in a custody dispute may want to verify that the other parent's new relationship does not expose the child to unsafe or unstable conditions. Someone who suspects a long-term partner of infidelity may seek documented evidence before making decisions about the relationship or pursuing legal action.
Licensed private investigators can legally conduct surveillance in public spaces, document observable behavior, photograph or video record individuals in areas where there is no reasonable expectation of privacy, and compile reports based on firsthand observation. They cannot access private communications, protected financial records, or sealed legal documents. Laws governing permissible investigative methods vary by state, so it is important to work with an investigator licensed in the jurisdiction where the subject resides or is located.
What kind of evidence will I receive at the end of a relationship investigation?
Most investigators provide a written report summarizing their observations, along with date and time-stamped photographs or video footage collected during surveillance. The format and detail level of that report will depend on the scope of the investigation and the number of surveillance sessions conducted. Your investigator should clarify deliverables before work begins so you know what to expect.
Can the evidence from a relationship investigation be used in court?
Evidence gathered by a licensed private investigator through legal means, such as surveillance in public spaces, is generally admissible in civil proceedings including divorce and custody cases, though admissibility is ultimately determined by the court and the specific circumstances of how the evidence was obtained. An attorney should review the investigator's findings before you attempt to introduce them in any legal proceeding. Using improperly obtained evidence can harm your case rather than support it.
