Yes. Having someone present during your initial consultation can be a source of great support.
You might ask your friend or family member to take notes on your behalf, so you can focus on listening and asking questions. Remember, however, that this is your consultation and it is important that the divorce attorney hears the facts of your case directly from you.
If you take a friend or family member to your consultation, the attorney-client privilege does not protect you from a breach of confidence. The attorney must hold your information in confidence, but there is no similar requirement for your friend or family member. If you take someone to your consultation, make sure you trust that person.
