School not issuing transfer certificate for my children while i contest domestic violence case

I have filed domestic violence case against my husband recently. I am married from last 15 years, but now as I am unable to bear the pain and cruelty done by my husband and in-laws, I have moved to my mother house along with my children of age 13 and 15. My sons are studying in 9th and 10th (passed recently and currently seeking admission for class 11th). As they have been admitted to new school near my parents residence, the school asking for TC and School leaving certificate. However, after numerous attempts, the school has denied the request stating that my husband have asked them not to issue TC to me. On further scrutiny I have found that my husband has lied to their nearest court saying that mother has no income and can not afford children's education hence, no TC to be issued to the mother, and have managed to get that letter from the court and presented to the school. NOTE: both the children are living with me by their own will and do not wish to live with their father or his family member. Any suggestion on this will be highly appreciated!
