What is the minimum time frame for disclosing expert witnesses in a legal case?

The minimum time frame for disclosing expert witnesses in a legal case is typically 90 days before the trial date. This timeline is set forth to ensure that both parties have adequate notice of which experts will be called to testify, allowing for proper preparation and cross-examination.

Disclosing expert witnesses 90 days in advance gives both sides sufficient time to assess the qualifications and opinions of the experts, enabling them to formulate their strategies for trial. It also serves to facilitate more efficient pre-trial proceedings, including motions in limine and other discovery disputes, by ensuring that each party can adequately prepare and assess any potential testimony.

The other time frames listed may either be too short or unnecessarily extended based on typical civil procedure rules, which articulate the 90-day rule as a standard approach in many jurisdictions. Thus, 90 days appropriately balances the need for timely disclosure with the fair opportunity for each side to prepare.
