no
The parent is supposed to get the child support, not the minor child.
No, they have to be told.
Yes. That is typically accomplished by disinheriting that child in your Will.
Your mother is not considered a natural heir, as you are expected to outlive her. And there is no need to 'disown' a child, you simply have to name them and say they don't get anything.
No, child support is only owed to the custodial parent/guardian. If the grandmother has become the custodial guardian, child support will be owed to her, instead of the mother.
Yes, if the non-parent has legal custody of the child.
No, child support does not start until the child is born. Once the child is born the mother can seek child support and it can be deducted from the father's pay.
Depends on your state, but odds are that you cannot. Child support is normally for a custodial parent. If you no longer live with that custodial parent, and are 18, you are an adult, not a child. Thus, you are not technically entitled to child support.
A parent must obey the child support order. A custodial parent may be serving in the military with the child under temporary guardianship. That is no reason to stop paying child support. If the child isn't living with the custodial parent who is receiving child support the matter must be brought before the court.
If you're in the US, no, a child cannot sue his parent for child support (payment for child support is not due to the child).
No. The purpose of collecting back child support is to financially reimburse the custodial parent for the support he or she provided in the past. It is not intended to provide present or future support. The debt is owed entirely to the mother in this case, since she was the one who provided financial support to the child. There are cases in which an adult can receive the back child support owed to their parent, but these usually involve the death of that parent.
Yes, if the father is the custodial parent. It works just the same as when the mother is the custodial parent. The non-custodial pay child support based on their income and other factors.
