Common questions
Should we respond before calling counsel?
Preserve the document and receipt proof first. The appropriate response depends on the document, stage, records and current law.
What should we avoid sending through general intake?
Do not send extensive books, privileged analyses or sensitive records until the firm confirms a secure channel.
Start with the document, risk and deadline.
An inquiry does not create an engagement. Conflict checking and written acceptance are required before the firm accepts work. Do not send extensive confidential material until the secure channel is confirmed.
