Hi. A quick background... The mother of our 3 children & I split a few years ago. We did alternating weekends of our children. Both of us have new partners & have married. Since my ex has been with her new partner, she has been slowly cutting my visitation down to nothing now. The 3rd one decided she couldn't stand to live there anymore as her mum was verbally abusive & unloving. And that her partner was extremely verbally abusive & physically abusive to the kids & my ex. Since then, she has refused me seeing the other 2 children at all & wants nothing to do with the 3rd, as she has said she is too scared to go back there whilst her partner is there. Recently, we had no other option but visit the kids at their school, where they advised us that one of them had had been hit in arm & thrown into a wall, bruises were seen. They both said they were unhappy there & didn't want to stay there. There drug use in house. My ex's partner had been arrested on numerous charges, etc. in front of them. Please don't judge me for not taking them then. I was unsure of my legal rights & it killed me to leave them. I went to the police & they advised me to apply for legal help (which I have done) & also that as I am on their school records as biological parent that I can legally remove them from school for safety concerns. So, we went to school & tried to do this. The school's answer was no as I'm not an emergency contact, even though they noted that I am the biological parent on file & also that they have been filing reports about the kids already to Families SA. Numerous Police visits & tones of reports to Families SA. I visited Families SA to which their file was brought up & the lady proceeded to mouse wheel scroll through the mass amount of reports. How can I protect my 2 children whilst I wait out legal solutions? What are my actual family law rights to keeping them safe?
