My niece (13 years) and nephew (11 years) have been living with me for nearly 3 years. My other nephew (6 years) has also started being in my care for 6 months. Their parents are drug users, no longer together - father is now homeless and mother cannot provide a good environment for the kids. I don't want to get their parents in trouble with the law so don't want to tell child protection they use drugs. I was just wondering how do I go about adopting, fostering or having some kind of legal permanent guardianship (e.g. adoption Australia) of the 3 children so that all paperwork to do with their schooling and medical things are under my control and I don't need the mother to sign for everything. The mother is happy to have me permanently look after the children and all the children want to live with me too. I am 31, married.
