Laboratory or technical expert costs

Use this page to separate laboratory or technical expert costs from other DUI-related expenses and verify each amount with the lawyer, court, agency, insurer, or provider that actually charges it.

Documents or quotes to collect

  • Expert engagement letter
  • Hourly rate/retainer
  • Records-review estimate
  • Travel/testimony rates
  • Cancellation terms

Questions before paying

  • Is an expert actually needed for this issue?
  • What records must be obtained before review?
  • Does the estimate include testimony or only consultation?

Do not rely on a national average

DUI-related costs vary by jurisdiction, case stage, provider, and services actually used. A written local quote or official fee schedule is more useful than a national “average DUI cost.”
