Ordinarily child support will cease on the child's 18th birthday unless there are mitigating circumstances. If it's a case of back child support, it is owed to the custodial parent who carried the financial burden during the period of nonpayment.
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.
Generally, no.

Well it depends on the law of the country and demands of the parent (the one that's living with the child).
When a parent moves to Germany, and has children in the United States, he does have to pay child support. If he is evading child support; Germany will demand he continues to pay support.
