For an Interrogatory, is the Plaintiff required to give evidence to the other parties attorney, if requested?

Interrogatories do not require production of documents, however a request for production does. If they have requested photos, videos etc. in a request for production you can make copies of said documents / items and produce them, or you can tell the other side what you have and say they are available for inspection and copying at a mutually agreeable time and place. You can also reach some sort of agreement for copying said items at their cost. Also you might have valid objections to said request which would prevent the production but there is no way to answer that without seeing the discovery. You might want to visit with a lawyer about your situation. Good Luck.
