Your question includes some ambiguities that make it difficult for me to answer. For example, you say the child support was set after they married but was for before they married. This would imply that this was retroactive child support, as opposed to ongoing child support. If you owe retroactive child support, this is a debt and you must keep paying it until paid in full. If it is ongoing support, then you must keep paying it unless it is modified by the court. The fact that the father is deceased does not end you obligation to pay support to whoever has your children. However, the father being deceased could be grounds for you getting custody of the children. You would have priority for custody over the step mother, unless she adopted the children, in which case you have no parental rights. While you say she adopted them, this might be incorrect. I have had a number of parents advise me that grandparents, or a step parent has adopted their children, when, in fact they just obtained legal custody, which is not the same as adoption. If in fact there has been an adoption, then your obligation to pay ongoing child support ends on the date of the adoption (you would still have to pay retroactive child support).
