Well, that's ridiculous. I'm presuming you are talking about the title insurance commitment which is issued prior to closing. You are PAYING for this work product and you are entitled to receive a copy for your review prior to closing.
If your title insurance agent is refusing to provide a copy of the title insurance commitment, FIRE THEM and go find a professional title agent who respects you, the consumer - YOU, the one who pays their salary.
If you're in a time pinch and can't afford to lose the time of going to another title agency, then find out who the regulator for title insurance is in your state - probably the Department of Insurance. Call them and complain. Perhaps they will call your title agent and educate them on consumer rights. Good luck and I wish you success.
