My son is 5 years old. His father has never had much involvement in his but to make matters worse his father is now in jail for what looks like at least 4 years. We live in Ny and i was wondering whether or not my son's father is still required to pay child support for the time he is incarcerated or whether he is responsible for it when he comes out. Does it just add up while his father is away? What can i do or what do i have to do? My son's paternal grandmother has been paying the child support for her grandson since it started when my son was a year old. So now that her son is in jail im not sure that she will continue to make the child support payments.
