FAQ
Questions clients ask first
How do I get started with an investigation?
Initial contact can be made by phone, email, or through the website contact form. A preliminary discussion helps clarify objectives, scope, and whether investigative services are appropriate for the situation.
How is confidentiality maintained?
Confidentiality is treated as a core operational requirement. Information is handled under strict internal controls, with access limited to authorized personnel involved in the investigation.
How long does an investigation take?
Time-frames vary depending on the nature, complexity, and scope of the case. Estimated timelines are discussed once objectives and investigative parameters have been defined.
How are investigation costs determined?
Investigation fees are determined based on the defined scope, resources required, and the complexity of the assignment. Costs are discussed in advance once objectives and parameters are established, ensuring clarity before any investigative work begins.
Can the evidence be relied upon?
Findings are documented using lawful, professional methods and assessed for accuracy, relevance, and context. Where applicable, documentation is prepared to support legal review or further action, with clear limitations noted where required.
