Frequently asked questions
What should I provide initially?
Send the client type, city and state, deadline, requested service, and a short non-confidential description. We will provide secure-delivery instructions if sensitive records are needed.
When does work begin?
Work begins only after conflict, jurisdiction, authority, scope, contract, and any required retainer are completed.
Do you guarantee a particular result?
No. Investigations develop and document facts reasonably available within the accepted scope; no evidence, activity, cooperation, or outcome is guaranteed.
