It depends on the state. If your state calculates child support based on household income, then yes, she would be required to pay her husband's child support. If your state calculates child support based on only the non-custodial parent's income, then no, should would not be required to pay. However, her husband would still owe that money, and it will continue to accumulate as a debt until he pays it.

Child support needs to be decided on by the court. In most cases, the noncustodial parent is responsible for something. If the custodial parent makes considerably more than the noncustodial parent, monies many not even be exchanged. To resolve this issue, it is best to file papers at your court house.
Yes. They are still the child's parent and responsible for supporting their child.
