I have three kids by my ex husband. I have since our divorce became unemployed. I have been for the last 3 years. We were divorced in 2005. Due to his first children coming off child support completely and his raises and my children needing more things. It is also hard for me to work due to he never visits or calls them. I am the sole care giver. I do it all, no help. Is it possible for me to receive an increase and I don't know his new address he is in the military.

You can request an increase by filing the proper paper work in your state. No guarantee you will get it. So, go to the local office and request it. You must list all changes in your living arrangements. Electric, food ,etc
