Attorney Services

We specialize in helping law firms overcome investigative challenges with tailored services including employee list research, witness outreach, asset investigations, and difficult service of process. Each case is handled with professionalism, discretion, and attention to detail.

Complete investigative support for employment law cases. For Class Action and PAGA wage and hour claims, we deliver accurate employee data, outreach, and plaintiff location services so you can proceed with confidence.
Trusted by attorneys statewide, we provide difficult service of process through investigative methods, strategic fieldwork, and clear documentation for cases where routine delivery is not enough.
Strengthen your case with verified financial intelligence. Our asset searches uncover real property, concealed holdings, and financial relationships, giving attorneys clear documentation for litigation and recovery.
Discreet support for complex probate and estate matters. As licensed investigators we verify assets, locate beneficiaries, clarify financial questions, and provide documented findings that keep filings moving forward.
Discreet, targeted monitoring that helps defense attorneys evaluate injury claims. We gather clear evidence of inconsistencies, exaggerated limitations, or behavior that points to fraud, documented for use in court.
Clear, factual insight into defendants and other parties in a case. We verify identities, review history, and surface details that affect credibility and risk, with discreet research and organized reporting for attorneys.
Court-aware documentation of conduct, lifestyle, and behavior patterns for family law matters. Our licensed investigators work lawfully and objectively, producing clear reporting for strategy, settlement, or evidence.
Discreet, results-driven missing persons work for litigation, asset recovery, and case development. We locate hard-to-find individuals and verify whereabouts for service of process, witness location, and heir searches.
We uncover objective information on assets, conduct, and credibility in contested family law matters, documenting relevant facts so attorneys can evaluate strategy, assess risk, and make informed legal decisions.
We investigate suspected misrepresentations, concealed assets, and improper filings in bankruptcy and foreclosure matters, helping attorneys evaluate risk, clarify facts, and determine whether fraud affects the case.
When a plaintiff stops responding, cases stall. We locate missing plaintiffs, witnesses, and other parties who have moved or disengaged, delivering documented findings so your legal matter can proceed with clarity.
Building on Employee List Research, our bilingual team contacts defendant employees for your Class Action or PAGA case, confirms eligibility, conducts preliminary interviews, and reports progress in organized updates.
We build defendant employee lists for Class Action and PAGA cases, organizing names and contact details into clear spreadsheets your team can use for internal review and the Witness Outreach phase that follows.
