If a title company allows the sale of a property when money is owed, are they responsible?

A title company called because they did not have a final lien wiaver signed for a property. They were told money was still owed on the property and that's why there wasn't a final lien waiver signed. However, even with this information available, they allowed the property to sell. Can they be held responsible for the monies owed if not paid by the general contractor?
