No - the new spouse isn't responsible for other men's children.
what if the noncustodial parent still reside with the custodial parent, is noncustodial parent still obligated to pay childsupport
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.
i am a custodial parent in Michigan. I've been to court to fight it, but unfortunately it is law that if the noncustodial parent is incarcerated they do not owe child support for the time that they are locked up. but if they owe back child support then you can seize anything they own.
Yes. The marital status of the custodial parent change does not change the obligation of the noncustodial parent.
If the non-custodial mother was responsible for full child support before remarrying, that responsibility will continue until the court says otherwise. The court will consider the financial condition of both the non-custodial mother and of the custodial father in deciding whether to continue to require full child support.
Yes, until the court order is modified.
In general, yes. The payments are for the children, not the parent. The step-parent is not legally responsible for the children unless he adopts them.
Yes. The fact that the custodial parent got married has no impact on child support.
In general, no. (I suppose the answer might be different if she married Donald Trump.)
