When critical problems arise, call on private investigators with local experience, local contacts, and a healthy knowledge of California law.
Martin Investigative Services (State License # PI 9077) is a licensed private investigation agency. Whether you choose us or another firm, always make sure your firm is licensed and legitimate.
Not all private investigators in California are the same.
As Martin Investigative Services is comprised of former supervisory Federal agents of the US Departments of Justice and Treasury, you will not find another firm in the country that has the level of surveillance and interrogation expertise that we do.
We strongly encourage that you contact us for a free, confidential consultation.
However, we realize you have many choices. If you’re going to look around, the following guidelines will assist you as you search, and help you avoid some of the many scams that are out there.
How to find a good private investigator:
In California, there are many private investigators, but there are really only a handful of talented, experienced and ethical ones.
If you don’t ask some basic questions, you may end up hiring someone who is out to rip you off.
The best way to hire a private investigator is by referral. Begin by asking trusted friends or colleagues if they have ever hired a private investigator, and more importantly, if they were satisfied with the services they received.
Given the personal nature of many cases, it might be difficult to find someone that has personal experience with a local private investigator. In that case, you may want to go beyond a basic Google search and try some of the following methods:
The duty agent at your local FBI, police department or sheriff’s department.
Your local law enforcement agencies will often have experience working with some of the more professional private investigators in California and, based on their experience, they may be able to recommend a few to you. Also, hiring a private investigator with good contacts in law enforcement certainly can’t hurt!
Investigators working at the District Attorney’s office and criminal defense lawyers.
Attorneys in California know full well the importance of working with private investigators can provide court-admissible evidence. Only experienced private investigators can provide this.
The California Association of Licensed Investigators.
This is a good starting point, however most associations like this will only list paying members. Private investigators are not required to join these associations and many of the talented ones (including us) do not.
