Yes. They are still the child's parent and responsible for supporting their child.
No - the new spouse isn't responsible for other men's children.
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.
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.
The obligation should not end, but rather transferred to the now nun-custodial parent.
In general, no. (I suppose the answer might be different if she married Donald Trump.)
No, the parent whom the child began residing would need to file for custody and also support before the original custodial parent would be obligated. However there would be no guarantee that a court would grant the motion.
As it is normally a part of the child support order, the custodial parent would.
