Start Your Research Investigation

Prior to accepting new engagements, HAI | Legal undertakes a standard conflicts check to ensure that we are free and clear to work on your matter.

For a conflicts check we will typically need the following information:

  • Your ultimate client
  • Adverse parties
  • Named co-defendants (if potentially adverse)
  • Name of specific sites (if applicable)
  • Type of legal or regulatory matter
  • Case citation for the legal matter (if available)

Once we confirm that we are clear to work on the matter, HAI | Legal will schedule a project briefing to discuss scope and potential level of effort.
