Don't take this wrong, I love online interaction and the QA that can go on... But you may want to investigate a new brokerage... this is something you should know and should have been taught to you by your broker. I could explain but it is not all the easy in text, very easy in person so feel free to call and I can go over it for you.
My suggestion that may be even better would be to call your title rep and have them tell you. This will help you build a relationship and may learn even more about the title process.
Not your fault... you just need to learn this as it is a HUGE part of protecting your buyer and seller clients.
Hope this helps!
