No, your fiance's child support is only his obligation and not yours. You are not responsible for his child support and they cannot consider your income, or take money from you. You may want to keep separate bank accounts from your husband because they can freeze his bank account if he fails to pay his child support. Further if he fails to pay his child support, they can intercept his tax refund, so you may want to consider filing separately. I suggest consulting with a tax lawyer or CPA on this issue however.
