My husband just recently went to court for back child support. The judgement was lowered to 25 per week because we are raising a grandchild (the child we are paying support ons child) She is 21 and in the prison. The arrears is almost 8 thousand and they are now sending us a notice that they want our income tax return. When we went to court the only thing they made a judgement on was the 25 per week nothing about the income tax return. My husband would not get any return if he was not claiming me and my children however my income is hidden in the business (I do bookwork and dont have a salary) so would an injured spouce be the way to go? Also I have read somewhere that they cannot take your income tax return for a child over 18.
