What if the investigation finds nothing?
You get an honest report that says so. A clean result still answers the question.
Can you help find a runaway or missing person?
Yes. We use people-location and investigative techniques to find family members and others who have left or lost touch.
Is surveillance legal in Simi Valley?
Yes, when done correctly. California allows observation in public places where there is no reasonable expectation of privacy. Our investigators do not trespass, use hidden vehicle trackers, or record private conversations.
Do you handle workers’ compensation and insurance claims?
Yes. We conduct claimant surveillance and claim investigations for employers, insurers, and defense counsel.
Can you serve someone who is avoiding service?
Yes. We locate the person first, then time service attempts around when they are actually there, and document service for the court.
Can you document cohabitation for a spousal support case?
Yes. Under California Family Code section 4323, a supported spouse living with a partner can create a presumption of decreased need for support. We document cohabitation for you and your attorney.
