Help Leonie and kids

Wow, this is harder than I thought. But here goes. A few months ago I decided to finally leave my abusing husband after 9 years of marriage and many attempts to make things work. We have two beautiful children, Benjamin (7) and Mekayla (5). I was a stay at home mom for most of our marriage because their dad was extremely busy and traveling a lot. Benjamin also has autism. In 2016 I started my business that grew and flourished but recently took a knock. I am currently in a situation where my children's father is not paying any maintenance, I moved out with almost nothing and all of our assets is in his name. He refuses to help and wants custody of the kids. I cannot allow that to happen and need to find a good lawyer to fight my case and it’s quite expensive. I never reported any incidents with the police as I was fearful to do so. In the meantime my kids need to go to school and my son needs therapy. I know we will get through this and I will grow and florish just like my business will. Thank you for your help, prayers and contribution.
