My son who had mental health problems which are now stabilised was divorced from his wife when their daughter was about 8 months old in QLD over 4 years ago. He came to Victoria to live with me (his mother) after suffering a nervous breakdown a few months after they separated. He has always been too afraid to contact his ex (I do not know why) in regards to their daughter whom he has not seen for about 2 years when I travelled up there for a visit. He has moved back to QLD, has secured employment, does some volunteer work and is getting his life back on track. I have tried calling his ex and her family and get the message to the bank and no call back, except for today when the phone was answered, muffled then hung up. No answer after that. He wants to see his daughter badly. What are his rights under Family Law, if any, and what should he do if she will take no calls from us? She works for a legal firm also.
