I have investments i want to leave to my son. He is the only family member i have. Should i put him on my investment account as joint tenant with right of survivorship? I am trying to avoid probate, but are there tax disadvantages in doing this? I do not want to leave him with a big mess. I would appreciate if someone could tell me how to handle this. I will be speaking with an attorney this week, but i like to be prepared so i know what is going on. We live in New Jersey. Thank You
