Will I automatically be placed in child support without consent from the mother of my child?

Child support is not necessarily automatic, but if the child's mother applies for any benefits with the State then a child support case will likely be opened and you could be required to pay child support in accordance with the guidelines.  If you choose to work something out with the child's mother outside of the Department of Revenue, then you will want to make sure it is documented, not only the amounts and dates, but there is documentation to establish that the money is for the benefit of the child and not a gift to the child's mother. Keep in mind, you can make agreements but the mother can still pursue child support at any time and if you are unable to establish that you have been financially supporting your child, then you can end up with child support arrears to pay in addition to any ongoing support that may be ordered.
