Karma is a great thing. The non-custodial parent will eventually lose if they did not file expressly to avoid the refund going to you. However, look at the IRS site for exceptions which allow not filing.
no
Yes, it can. Moving in with the other parent is grounds for "flipping" child support payments. However, this must be done by court order.
Generally, no.
yes
No.
yes
Yes. They are still the child's parent and responsible for supporting their child.
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.
The obligation should not end, but rather transferred to the now nun-custodial parent.
for what?
If the noncustodial parent tries to keep the child, the custodial parent can get the noncustodial parent charged with kidnapping and contempt of court both can be jail time for the noncustodial.
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.
