Hello, all. I am new to this so will keep it short. I want to know if anyone has advice regarding my situation. My partner's ex took his child (5-year-old) about 12 months ago interstate. While he did not give express permission she could leave, he also did not stop it as he was led to believe by her that he had no choice or say in the matter. Since leaving, she has not allowed him to have his son visit with him and he has only been allowed to visit once for one week. Communication between them has broken down and mediation was no help whatsoever, the agreements between them made in their sessions has not been adhered to (on her part). For example, they agreed my partner could have his son stay for a week or two over easter and once mediation ceased she has gone back on her word. She is constantly abusive and d would stalk both our social media and will not listen to reason. She will often not answer calls to let my partner speak with his son for days on end. Often we have no idea where his child actually is in regards to her family home, her partner's house or even in the state still. Any attempt to build a better relationship with her or to gain better communication with the child and she resorts to abusive messages and threats and often will turn her phone off for a day or so. We have no other contact numbers for her if she blocks our numbers like she has threatened. Often the calls she allows between my partner and his son are rudely interrupted or cut short by her if she doesn't like the conversation topic (e.g my partner telling his son he would like to see him and asking if he is behaving at school, etc.). I would say he is allowed to have contact with his son for an average of less than one hour per week on average by phone. He has also voiced concern to her about the possibility of her taking their child overseas without his permission as her close friends and family are all currently in America where she was born. She was given citizenship in South Australia two years prior to their marriage but has mentioned she will be taking their child to the USA to see family next year with or without my partner's permission. They are separated for over 18 months and are not divorced. There is no history of domestic abuse on his part. He currently pays child support each week and has never missed a payment, frequently tries to call (usually 4-6 nights a week) and often sends his son gifts. Sorry, this is such a long thread. We are seeking legal advice but the initial appointment seems to be taking some time. Any help would be greatly appreciated as we are at our wits' end, as are the rest of the paternal family. Thanks in advance.
