In litigation, it is vital to take witness statements in a timely manner. It serves to preserve witness memories while they are fresh in the form of a signed or recorded statement or even a declaration. It also identifies relevant information, helps in determining witness credibility, and it can determine the direction of the investigation.

Utilizing trained Paralegal expertise as a Legal Investigator, we provide in-depth pre-trial support in review of statements, reports, documents and public records, looking for evidence and inconsistencies, which may be applicable in your legal matter.

Attorney services have experienced increased difficulty with the advent of Ring type camera systems where the subject can remotely monitor who is at their door. We offer Difficult Service of Process as an alternative, when the attorney service is unable to complete service. We have had tremendous success via surveillance while providing evidentiary images of the person served!

Our team is dedicated to creating a detailed site inspection utilizing sketches, diagrams with measurements, and photographs, providing the attorney with a visual layout of where an incident occurred.

A well planned surveillance utilizing state of the art, digital equipment is crucial for evidentiary purposes when documenting impugnable activities in Family Law, Corporate and Civil Litigation.

LSIS uses multiple databases for cross referencing information to ensure we have the correct person identified via names, age, DOB, SSN, family, and known addresses. These proprietary information brokers obtain their records from secure sources, credit bureaus, court records, etc.

Background checks are essential in Family Law and Civil Litigation for screening opposing parties, witnesses and 3rd parties, as well as potential clients.

Internet and social media has become a gold mine of information posted by the subject of investigation or other sources, when building a case.

LSIS provides legally compliant, real time GPS tracking services to private clients and businesses, consistent with California Penal Code 637.
