Which type of disclosure has a deadline no later than 90 days before trial?

• A. Initial disclosures
• B. Expert disclosures
• C. Pretrial disclosures
• D. Interrogatories

Answer: (B)

The main idea here is the timing of disclosures that prepare both sides for trial. Expert disclosures have a 90-day-before-trial deadline, reflecting the need to allow time for reviewing expert opinions, deposing experts, and integrating their testimony into trial preparation. Retained experts must provide a written report detailing the opinions, bases, and data supporting them, and this timeline gives the opposing side adequate opportunity for challenge and preparation.

In contrast, initial disclosures are exchanged early in the case to share basic witnesses and evidence, while pretrial disclosures are due closer to trial and focus on what will actually be presented (witness lists, exhibit lists, etc.). Interrogatories are a separate discovery tool with their own response deadlines and are not tied to a 90-day-before-trial deadline. Thus, the type of disclosure with the 90-day deadline is expert disclosures.
