Legal Question in Civil Litigation in California

Most of the Form Interrogatories are a bit vague taken out of context. You need to read the question, including the definition of "incident" chosen by the party that served the FI's, and give it your most reasonable interpretation under the circumstances of the case, understanding that courts favor more rather than less disclosure. Generally "incident" means the whole package of events that the case is about, but not always. Only by knowing what the case is about can one properly interpret the question.

It depends, as Mr. McCormick states, on how the propounding party defined INCIDENT. That should have been checked on the beginning of the form interrogatories.

You have asked quite a few questions about form interrogatories, which strongly suggest that you are a pro per and that you are in over your head. You should consider hiring a lawyer to at least consult with you on your case.
