You cannot copy the definitions from the Judicial Council form interrogatories for use in specially prepared interrogatories.
If your special interrogatories contained impermissible definitions, these interrogatories are objectionable based upon Code of Civil Procedure section 2030.060, subdivisions (d), (e) and/or (f).
Therefore, if the responding party objected on the grounds that the interrogatories contained definitions, the defendant does not have to substantively answer the interrogatories. You won't be able to cure this defect. However, you should meet and confer with the opposing side to see if you can resolve the objections BEFORE you attempt to file a motion to compel further responses.
