My question involves collection proceedings in the State of: New York

I have been sent legal interrogatories, but I have not received anything from the court stating that I am being sued (like a summons with a trial date etc...).

Do I legally have to answer these questions since I have not been sued yet?
I thought interrogatories were sent after a lawsuit has been filed.....

This seems a bit strange to me.
I would really appreciate an answer.
Thanks.
