Common misconceptions

Our IT manager can testify. An IT manager can testify as a fact witness only. Opinion testimony requires FRE 702 qualification.
We can hire after fact discovery closes. Most courts require expert disclosures earlier. Plan retention well before the deadline.
All experts charge the same. Rates vary by experience, certification, and prior court qualifications. Ask for a rate sheet upfront.

When this applies and when it does not

Applies. Disputes where digital evidence is in play: contested communications, suspected unauthorized access, contested device use, employment disputes, family law, civil litigation, criminal defense, and corporate investigations.

Does not apply. Routine IT support, system recovery without a legal context, or matters where the digital evidence is not actually in dispute.

What matters most

  • Independence. An independent examiner with no conflicts produces credible findings.
  • Court qualification. Prior court findings of qualification carry weight at hearing or trial.
  • Documented methodology. Findings are only as defensible as the method behind them.
  • Speed of preservation. Cloud, log, and carrier retention windows are short. Act early.
  • Clear written reports. A report a judge or juror can follow is worth more than a thick technical brief.
