Answers before you call.
Reports, photographs, video, records, and investigator testimony may support a legal matter. Whether particular evidence is admissible or useful is a legal question for your attorney and the court.
No. Many clients contact us because something does not add up or because they need to document a concern. We can discuss what you know, what you need to establish, and whether an investigation is likely to help.
Cost depends on the service, time, travel, personnel, research, equipment, urgency, and reporting needs. Once we understand the assignment, we can explain the proposed scope and budget.
Information submitted through the contact process is treated discreetly. Tell us the safest method and time to respond, especially when another person has access to your phone or email.
