Was the lawyer reviewing the title commitment on your behalf or was the lawyer the title agent issuing the title commitment?
If the lawyer was hired by you to review the work of the title agent, the lawyer might have thought his own review on your behalf was sufficient. A lawyer acting on your behalf is your fiduciary, hired to protect you. I would have preferred that the lawyer share a copy with you so you understood the property rights before you closed, but you hired the lawyer and the two of you should review your expectations of the agreed work relationship.
If the lawyer was the actual title agent issuing the title commitment, he had a duty to release a copy of the title commitment to you prior to closing. If the lawyer was the title agent AND your legal representative, he was performing under a conflict of interest. A lawyer can't or shouldn't serve more than one master. In this case the lawyer would be representing the title company and your interest would be secondary. This is a common problem. Doug Miller, a lawyer who blogs, discussed thid very issue.
