I am buying a house in southern nj my attorney is in central nj. My real estate agent told me I can't use him. Is this true

There are title companies and realtors in South Jersey that do closings without attorneys.  I do not think this is a good idea beause there is no one at the table to protect your interest.  The title is only interested in clear title being passed, and the realtor is only interest in getting a commission.  The attorney is there to protect you.
