Witness Preparation Ethics Boundaries

Prerequisites
- Jurisdiction and governing ethics rules (state bar, local court orders).
- Witness type and setting (fact or expert; deposition, hearing, trial).
- Core materials: pleadings, key documents, prior statements, discovery responses.
- Any in-court communication limits (Geders, Perry).
