Get my family out of an abusive household

Me and my family finally escaped our abusive fathers household and were finally feeling happy. However, now he is taking my mother back to court and currently has custody of my two younger siblings again. I am going off to college soon and my mom is still paying off her last lawyer from last year still so anything raised from this will go directly to funding a lawyer new for her. Please help my siblings get out of his mentally unstable and verbally abusive house before it is too late. Every donation is greatly appreciated!
