Private Investigators

Our private investigators find proof to protect you, your family and your business.

If you think you need a private investigator, then you have a serious personal or business issue that requires expert assistance. Private investigators find proof and information that protects you, your family or your business.

A professional private investigator is licensed, has extensive experience, abides the law, advises you on your situation (without interest for themselves), and explains what they can and cannot do to help you. And they should always give you a free consultation.

Our professional private investigators are ready to help you.

    Private investigator in a California court of law

    Can the private investigator testify in a court of law?


    In the litigious state of California, a good private investigator will know the system and how to work within it. Investigations should not only yield court-admissible evidence but your investigator should also be able and ready to testify in support of this evidence. Many private investigators do not have this experience or background.

    The private investigators at Martin Investigative Services have years of experience gathering court-admissible evidence and are ready to supply expert testimony in court.

    Private investigator office locations in California

    Does the private investigator have an office?


    A professional private investigator will always have an office, if not many offices. It is especially common in California for private investigators to not have offices, preferring instead to meet at restaurants or communicate by phone or email only. These investigators should be eliminated from consideration as you need to know you'll be able to locate this person again once you've handed over a payment.

    Martin Investigative Services has local offices throughout California: two local offices in Orange County (in Newport Beach and Mission Viejo), as well as field offices in Los Angeles and San Diego.

    Call (800) 577-1080 for a free consultation.



    A professional private investigator or businessperson in general should clearly define the fees involved.

    Does the private investigator clearly define the fees involved?


    When you contact a private investigator, explain the service you would like performed and ask how much it will cost. Just ask. A professional private investigator will provide an accurate estimate and will not exceed the quote without your approval.

    Martin Investigative Services will always provide you with an estimate upon our first conversation.

    Call (800) 577-1080 for a free consultation.



    Meeting with a private investigator.

    Do you have a good gut-feeling about the private investigator?


    Private investigators know that very often your intuition is correct. When you speak for the first time, ask yourself if you feel a good about it. What is your immediate gut reaction?

    Make sure the private investigator thoroughly understands your situation and that you feel comfortable. You should feel he/she is looking out for your best interests. Your needs should always come before money.

    Call (800) 577-1080 for a free consultation.

Case Study: Private Investigation

Private Investigation Case Study

Orange County Murder Cold Case


We first met our client through a conference call with the client's family and their attorney, a prominent Orange County attorney.

The client strongly believed that her friend was shot and murdered by her husband. Local police had concluded the case was an accidental shooting.

Results:

After a 9-month investigation, our private investigators gathered enough evidence to prove our client's suspicions were correct. We turned our evidence over to the Orange County District Attorney and the husband was arrested.

Martin Investigative Services has investigated hundreds of cold cases like this one. If you need our help, please contact one of our private investigators us for a free, private consultation.
