No. Child support is paid by non custodial parent, not step parent. Income of a New Spouse: Contrary to common belief, Illinois law permits judges to consider the income of a second spouse when establishing or modifying child support awards. The door swings both ways, too. A custodial parent who remarries a well-to-do spouse may suffer a reduction in child support to be paid by the non-custodial parent.19 Likewise, a non-custodial parent who remarries a spouse of substantial means may be required by the court to pay a higher child support than if the marriage had not taken place. http://www.illinoisdivorce.com/family_law_articles/etsblishing_child_support.php
A person is not responsible for their spouse's child support, so no, the court doesn't consider their income in setting child support.
The income of your ex-spouse's partner is irrelevant to child support; only your ex-spouses income counts.
if you are paying child support and have a new spouse, their income will not count toward child support unless the two of you have your own children together.
The new spouse is not responsible for his/her spouse's children.
No, not the whole household's income, just the ex-spouse's income. If he/she is remarried the new spouse's income does not count. Only the biological parents pay for their child.
Generally, no. It is based on your income and not your expenses.
No, child support is based on the biological parents income. no one elses.
