Can my new spouse's income be used against me?

So you lucked out on your second marriage and married a bazillionaire who makes tons of money? I know what you're afraid of: your ex will take you back to court to raise your child support based on your new spouse's income.

Don't worry, although there are rare circumstances where a new spouse's income or wealth can affect child support (maybe you previously claimed an inability to make back payments or something like that and now your expenses are reduced such that you can afford the back payments nowe), but child support is based on the income of the parents, not the income of new spouses. You should be fine.
