Thomas is very personable, professional and honest. He made every effort to help, and was successful despite less-than-favorable odds. After trying to work through the case on my own for years, Martin Investigations was able to find the information I was looking for quickly. I was very impressed.

Frequently Asked Questions

Whether private investigators are worth it depends on your specific needs and the complexity of your case. They can provide valuable services and expertise, but it's essential to consider the cost, legal implications, and potential outcomes before hiring one.

Yes, a private investigator (PI) can track your phone with proper legal authorization. They often use GPS tracking devices or software to monitor the location of a phone, but they must adhere to privacy laws and obtain consent or a court order for such surveillance to be legal.

Legally, a private investigator cannot bug your phone without your consent or a court order. Wiretapping and electronic eavesdropping without authorization are illegal and can result in criminal charges and civil lawsuits against the PI.

To verify if a private investigator is licensed, check with your state's licensing board or agency responsible for regulating PIs. You can typically search for their license status online using their name or license number.

Private investigators adhere to a strict code of ethics, including respecting privacy, ensuring confidentiality, and maintaining honesty. They must operate within legal boundaries, avoid conflicts of interest, and provide accurate information to clients. Ethical PIs also prioritize the well-being of individuals involved in investigations and uphold professional standards in their conduct.

Yes, it is legal to hire a private investigator in California, but the PI must be licensed by the California Bureau of Security and Investigative Services. Ensure they have a valid license and follow state regulations.

Hiring a private investigator (PI) for pre-employment screening can provide thorough and discreet background checks, going beyond basic employer checks to uncover details like past behaviors or undisclosed information. Consider the cost versus the depth of investigation needed. PIs may access information not readily available through standard channels, navigating privacy laws to legally obtain critical information.

The purpose of a private investigator is to gather information and evidence for clients. They conduct investigations for legal, personal, or business matters, including background checks, surveillance, locating missing persons, and investigating various types of allegations.

Being a private investigator can be risky, as the job often involves dealing with sensitive information, potentially dangerous situations, and sometimes confrontational individuals. Investigators must be cautious, well-prepared, and aware of their surroundings to minimize risks.

Yes, a civilian can hire a private investigator for various personal or business-related investigations, such as background checks, surveillance, locating missing persons, and gathering evidence for legal cases.

You might use a private investigator for background checks, gathering legal evidence, investigating infidelity, locating missing persons, conducting surveillance, and verifying information for personal or business purposes.

People hire private investigators for various reasons, including gathering evidence for legal cases, conducting background checks, locating missing persons, investigating infidelity, and conducting surveillance for personal or business matters.

The best way to locate someone is to hire a private investigator who specializes in locating missing persons. They use various methods, including public records searches, surveillance, and online databases, to find individuals.

To locate someone, you can start by searching online databases, social media, and public records. If these methods are unsuccessful, consider hiring a private investigator who has access to specialized databases and resources.
