My son's ex has just given birth to twins. there is a DVO ( domestic violence) in effect. He has not been informed of the birth and is not aware of how they are all doing. He is to appear in court and will be sentenced for the duration of his probation due to breaching the DVO and driving under suspension. Under family law, am I able to contact his ex or her family without breaching the DVO to find out about my grandchildren? Also, am I able to have visitation with my grandchildren ( grandparents rights)?
