How can I know if someone is using my license?

I not reinforcing anything im just saying call the board and see what they say. Thats it.

Probably the board can create a new lic. number for him and they can put a note saying that the old lic number is voided from the date he thinks he missed till the new date of the new number...that way in court if something happen its been reported that it was stolen if the drawings were stamp between those days...i dont know that me thinking what they can do.

Sorry... I must have misunderstood. You're seemed worried about "in court" and "drawings were stamp". I thought that was reinforcing paranoia.
