"Tips for Working with Expert Witnesses," by James L. Ewing and Jason D. Gardner, contains a lot of useful information even though the article is tailored specifically to intellectual property litigation. (Note: link is to a pdf file.) Topics covered include:
- Selecting and retaining experts;
- Working with experts;
- Preparing experts to testify; and
- Taking the adverse expert's deposition.
The last section of the article can be used as a foundation for deposing an adverse expert in almost any case. It's informative--but short too!
