Is Direct Focus Investigations (DFI) Licensed and Insured?
Yes, it is imperative for the Investigation Service Company working on your case be licensed and have liability insurance.
Where do you serve?
We serve all of Los Angeles, Orange, Riverside, San Diego and Imperial Counties in Southern California.
What is needed to begin surveillance on a subject?
D.F.I. will ask you to describe and provide a photo (if you have one) of the subject to be surveilled, as well as any information regarding their location, including home address, their place of employment, and any information about their vehicle.  This type of information will assist us in getting your case started.

After the D.F.I. investigators gather the information you requested, they will document their investigative findings in a written report, which often includes photographs and video. D.F.I. investigators will provide courtroom testimony if needed.

How fast can a private investigator start working on my case?
Your investigation can begin quickly if you work closely with us in getting the necessary information to start working on your case in a timely fashion.

DFI prefers at least 24 hours notice before beginning any investigations to properly prepare.

However, in certain circumstances, we can start an investigation in one to three hours if the situation is genuinely urgent.  Weekends are usually the busiest time for our Investigators in the Los Angeles, San Diego, Orange and Riverside Counties; therefore, a 24-hour notice is generally needed for weekend assignments.

Keep in mind that we will not begin the actual investigation until we have collected all the information and retainer, along with a few forms to ensure client confidentiality.

How do I get started?
First, you will need to schedule a phone call to discuss the details of our retainer.

We require retainer payments before any case begins, and we can process major credit cards (V/MC/Discover/AMEX) over the phone. You can call our offices 24 hours a day for further details, and we look forward to speaking to you about your investigative needs.

I can’t endorse him highly enough!”

Case Studies

Here are our blog posts and case studies regarding issues and situations we have worked with.

Missing Person Case Study

Missing Person Case Study

A woman contacted us because her 19 year old son was missing and hired us to find him. She explained to us that he had chosen to leave and did not know where he was. We advised the client up front that most of the time when an adult child leaves, it is because that is their choice and while we will most likely be able to locate him, he is an adult and legally does not have to come home.

Cohabitation Case Study

Cohabitation Case Study

A man came to us with a suspicion that his ex-wife was cohabiting with another man.  In their divorce agreement he was to pay her $2,500 a month in spousal support (alimony).  Which in order to receive spousal support or alimony, the person receiving the support must live alone. Read what we found and how it concluded.
