Clear answers before an engagement begins.
Case information is handled on a need-to-know basis using controlled communication and reporting procedures. Specific arrangements can be agreed during the initial consultation.
Timelines depend on scope, location, complexity, access to information and the type of evidence required. Expected milestones are defined before work begins.
Reports are delivered through agreed secure channels and may include findings, supporting material, context and limitations.
The initial discussion clarifies the concern, intended outcome, sensitivity, available information and practical constraints.
Fees depend on scope, duration, geography, specialist resources, urgency and reporting requirements.
