Do You Suspect Your Loved One Is Cheating?

Private Investigators Specializing in Catching Cheating Spouses and Partners

Whether you’re married, in a committed relationship, or getting divorced, you deserve to know if your romantic partner is or has been cheating on you. This is especially important for married clients seeking an annulment or for those with a prenuptial agreement that includes fidelity clauses. Also, having advance knowledge about an affair can help clients protect themselves financially, especially in cases where they share assets and/or living arrangements with their partner. For these and similar circumstances anywhere in Los Angeles, Exell Investigation is standing by to provide competitively priced investigative services. In cases of infidelity, an investigation package might include undercover surveillance, Internet activity monitoring, records search and retrieval, and GPS tracking (for couples who share ownership of a vehicle).

Highly-Trained Detectives Licensed by the Bureau of Security and Investigative Services

In business for more than 20 years, Excell Investigations has an excellent reputation for giving clients the information they need to make sound decisions about their relationships. Our private investigators are licensed, well trained, and highly experienced (10+ years, on average), ensuring they deliver high-quality investigative services that are always compliant with local, state, and federal laws. Throughout the duration of the job, our agents remain accessible via phone or email; provide updates; and, at the job’s conclusion, deliver a comprehensive report with surveillance photos and/or videos. Although we focus on providing local infidelity investigation services in the Greater LA area, we have, on occasion, accommodated client requests to travel out of state (as far as Las Vegas) to catch cheating spouses and partners.
