No. Your obligation to support your own child takes priority over any subsequent support you offer for another person's child. The court would not decrease your child support obligation for that reason.

Whether or not you have to pay child support if the child is living with the noncustodial parent depends on the support order that it is in place Typically you can expect that you will have to expect to pay support.
