Expert Witness Guides
An entry on this site answers one question about one rule or one stage of an engagement. A guide runs the sequence. The three pillars below track the order the questions arrive in: getting an opinion admitted, retaining and working with the expert who gives it, and taking apart the one on the other side.
Start with a pillar
What the proponent of an expert opinion has to establish, to whom, on what record, and what the 2023 amendment changed about it.
Exclusion is the exception, not the objective. What a Rule 702 challenge produces, where the weight line sits, and the order a challenge is built in.
Designation, conflicts, terms, the file and the testimony, in the order they actually happen — and where the reversals stop being possible.
Look up a rule instead
Every rule, motion and stage named in these guides has its own entry in the reference.
