I wouldn't do it without written approval of child support enforcement and/or the court. Get a printout on your payments from CSE first. I do hope you're paying through them and with a court order, otherwise anything you're paying could be considered a gift.
In most cases, states will give you a "credit" on your child support obligation based on the over-paid amount. This will reduce or even eliminate your monthly child support payment until the credit has been used up. Very few states will issue a cash refund for the over-paid amount unless the child is approaching the age of majority.
Depends on the state. Request it from the person who received the support first, if not, check you state laws as some allow for you to sue the receiving party.
Generally, no. Not even if you learn you're not the father.
That's dependent on the state. Account practices are generally not set up for or it so a modification must be filed as regards future payments.
If you were overpaid, yes.
yes
No. The money isn't for the mother. The money is for supporting the child. Back child support belongs to the estate of the deceased and will eventually benefit the child. And even if the child should die, the back child support does not go away.
Depends on your state laws. Some states have laws that any overpaid child support can be requested from the parent who received the support and if not, you can sue them for the overpayment. Check on your local state laws. Answer You must request the court (most forms are readily available at the courthouse or online) to end the responsibility. Otherwise, you are still on the hook for payments. If the child is in college, it may be that child support will continue--just depends on your agreement. Overpaid child support? Consider leaving the situation alone and moving on with your life.
Presuming you have overpaid your tax through estimated payments or withholding enough to warrent it, yes.
This is a growing problem due to fathers not monitoring their payments and getting regular printouts from CSE. Plus, there are interest penalties, so you may not have overpaid. see link
no
No, you cannot get money back that you paid in child support. There may be circumstances where you could sue a person for some of that money back if you found out the child was not yours.
No. Back child support is money you should have been paying when you didn't. You owe it until it is all paid up.
Get a DNA test. Then if it proves the child isn't yours you won't have to pay child support. You might even be a able to get back the money you have already paid in child support.
Any money designated as taxable income is subject to garnishment for child support.
The courts must approve any waiver or settlement of back child support. This is because, strictly speaking, the money is for the child, not you.
