From Infidelity to Identity Theft: The Most Common Reasons People Hire a PI in Los Angeles

Los Angeles area private investigators - Consult Kinsey Investigations.

When most people think of a private investigator, their minds jump to Hollywood-style surveillance scenes, complete with trench coats, high-speed chases, and whispered phone calls from dark alleys. But in the real world – especially in a city as dynamic and complex as Los Angeles – the work of a private investigator is far more nuanced, and the reasons people hire them are more varied than you might expect.

At Kinsey Investigations, a woman-owned private investigation agency based in Los Angeles, we’ve worked with countless clients from all walks of life: concerned spouses, overwhelmed parents, business owners, attorneys, and even celebrities. Despite the diverse clientele, certain patterns emerge in the types of cases we see most often. People don’t just turn to private investigators because they want to catch a cheating partner (though that remains one of the top reasons). They come to us because they need clarity, evidence, peace of mind, or support in situations where traditional resources have failed them.

And let’s face it – Los Angeles is a city where appearance isn’t just everything: it can be the difference between personal fulfillment and public fallout. With so much at stake, it’s not surprising that many people feel they can’t rely solely on public institutions to resolve their concerns. Sometimes, what you need is a neutral third party with the tools, training, and tenacity to uncover the truth, no matter how hidden it may be. Whether it’s for deeply personal matters or high-stakes corporate concerns, the role of a private investigator is to bring light to what is hidden and provide a clearer path forward.

In a city where the stakes are often high – whether it involves personal relationships, legal battles, or professional integrity – having a skilled, licensed private investigator on your side can make a real difference. This blog post explores some of the most common reasons people hire a private investigator in Los Angeles. If you’re wondering whether a PI might be able to help with your situation, read on. You might be surprised to find just how much we can do.

Suspected infidelity - Consult Kinsey Investigations.

  1. Suspected Infidelity

Catching a cheating spouse is still one of the most frequent reasons people hire a private detective. Whether it’s unusual behavior, secretive phone calls, or sudden unexplained absences, suspicions of infidelity are emotionally devastating. At Kinsey Investigations, we approach these cases with both empathy and discretion, providing clients with photo and video evidence that is legally obtained and court-admissible if needed. The goal isn’t just to catch someone in the act – it’s to give our clients the information they need to make empowered decisions about their relationships.

In some cases, the truth can be surprisingly comforting. We’ve worked with clients who were relieved to learn that their partner was not cheating, but rather dealing with other life challenges such as financial stress or mental health issues. In either case, knowledge brings power – and often, peace.

  1. Child Custody Investigations

Custody battles can be complex and painful, especially when the safety and well-being of a child are at stake. Parents may suspect that the other party is exposing a child to unsafe conditions, neglect, or even illegal activity. In these cases, a private investigator can document evidence of abuse, substance misuse, or other behavior that may influence a judge’s custody decision. Our team often works closely with family law attorneys to gather the information needed to protect a child’s best interests.

Beyond courtroom applications, this evidence can also be critical in co-parenting negotiations, helping parents establish clearer boundaries or adjust visitation schedules in the child’s best interest.

  1. Background Checks

Not all reasons for hiring a PI involve dramatic or high-stakes scenarios. Sometimes, clients simply want peace of mind before entering into a new personal or professional relationship. Whether it’s a potential nanny, business partner, or romantic interest, a comprehensive background check can uncover red flags that wouldn’t show up in a basic online search. At Kinsey Investigations, we go beyond surface-level checks to provide detailed and accurate information that helps clients make informed decisions.

We also work with landlords, employers, and investors who want to verify someone’s identity, criminal history, employment record, or financial standing before making a major decision. In today’s world, due diligence isn’t just smart – it’s necessary.

Missing person investigation - Consult Kinsey Investigations.

  1. Missing Persons

From long-lost relatives to runaway teens or individuals who have simply disappeared, missing persons cases are among the most emotionally charged assignments we take on. Law enforcement agencies are often overwhelmed and limited by jurisdiction, which means that many families are left without answers. Our investigators use a combination of database research, interviews, and on-the-ground work to locate missing individuals and reunite families.

In many cases, time is of the essence. The sooner we can begin a search, the better the chances of locating the individual safely. Unlike public institutions, we aren’t constrained by bureaucratic delays – we move quickly and strategically.

  1. Identity Theft and Fraud Investigations

As cybercrime continues to rise, more people are turning to private investigators to track down identity thieves or fraudulent activity. Victims of identity theft often feel helpless after reporting the crime to banks or law enforcement. We help trace the origin of the breach, gather documentation, and, in some cases, identify the individuals responsible. Our team also works with corporate clients dealing with internal theft or financial misconduct.

In a digital world, many perpetrators hide behind online aliases and fake profiles. Kinsey Investigations specializes in digital forensics, helping uncover the truth behind anonymous accounts, suspicious emails, and fraudulent transactions.

  1. Workplace Misconduct or Harassment

Businesses, both small and large, hire private investigators to look into suspected employee misconduct, harassment claims, or compliance issues. A discreet investigation can reveal whether inappropriate behavior is taking place and help protect the company from potential legal liabilities. We also assist in gathering evidence that supports HR decisions or legal claims.

When employees feel unsafe or unheard, productivity and morale plummet. By bringing in a third-party investigator, employers show that they take allegations seriously and are committed to a safe, respectful workplace.

  1. Surveillance for Legal Cases

Attorneys frequently rely on private investigators to conduct surveillance that supports civil or criminal cases. Whether it’s documenting insurance fraud, locating hidden assets in divorce proceedings, or verifying alibis, surveillance can provide critical evidence that helps build a strong case. Our surveillance is always conducted within the bounds of California law, ensuring it holds up in court.

Video and photo documentation, timestamped reports, and expert witness testimony are just a few of the ways we support the legal process. We’re often called upon to provide insight that turns the tide of a case.
