A lawyer in a dream indicates that you are going through a hard time and having trouble with someone. It can also suggest that you are afraid of breaking the law or taking actions that will enable you to break the law.
The dream of a lawyer representing you in court can also signify other things. When the lawyer is held in higher regard as a symbol for justice, it suggests that there shall be peace and victims will receive fair treatment; and when something causes the lawyer to lose respect, it indicates that people might not be treated fairly.
