03
Ask who will manage the matter, how the scope will be defined, what documentation may be produced, how updates will be provided, and which practical or legal limitations apply. Fees and authorization should be clear before investigative activity begins.

Questions, answered
ATB Investigations treats consultation information discreetly and requests only information relevant to evaluating the matter. Specific questions about legal privilege should be discussed with qualified counsel.

No. An investigator can collect and document facts within an authorized scope but does not replace an attorney or provide legal strategy.
Cost depends on scope, time, location, required methods, and complexity. ATB Investigations reviews the objective before discussing an appropriate scope and fee arrangement.
Timing varies with the objective, availability of records or subjects, and changing case circumstances. No responsible investigator can promise a universal completion time.
No. An investigator can pursue an agreed lawful scope and document findings but cannot guarantee that evidence will confirm a belief or produce a desired outcome.
Ask for the investigator’s license number and verify it with the appropriate state licensing authority. ATB Investigations identifies its California private investigator license as PI #24646.
Investigation findings may assist counsel or a legal matter when collected and documented appropriately, but admissibility is decided under applicable law and court rules. Coordinate with your attorney before work begins.
