Help with my daughters braces

Description

Good day I want to start with I hope everyone is enjoying their summer thus far! I'm making this post because I recently left my abusive husband with my 5 children, my daughter has braces that my husband would pay monthly on. Well I just got a message the 22nd of this month stating that $1,460 I thought my husband was paying on them monthly but I guess he wasn't. The child tax always went into his bank account he always had a stable job and income but was very abusive and controlling so I never worked always stayed home taking care of our children and the house! Now that I've left I have no income I've called childtax but I need proof that the children wont be living with him again and also need to separated from my husband for 3 months before income assistance will help me with anything. I was trying to work out a payment plan with the orthodontist but because there's already a contract it cant be redone so I'm stuck trying to come up with this money before August 5th so her braces wont be removed. If anyone is able to help with anything I'm able to provide any information someone might need to help! Thank you everyone for reading my post and I hope you all are a great day and rest of summer! God Bless
