I've been on both sides of this situation and let me tell you, it sucks. When my ex first left, he was responsible for paying child support
. I tried to get DCSE to cancel, but I had received food stamps for a couple of months. His child support was required to pay them back before our case had any chance of being closed. He went to jail, his family paid the support to get him out, and life went on.
A few years later, custody changed hands. I was then responsible for paying child support. When the amount was figured, I had recently lost my job due to an injured ankle. The General Master stated that CS would be calculated based on my earning potential if I had a full-time, minimum wage job, plus child care. When I got about $2000 behind, I went to court with the potential of going to jail, though my parents were able to help me. DCSE has been very strict about making sure that I have been up to date on my payments. I too live in FL.
In my experience, judges don't care about your inability to find a job, how many other kids you have, or whether you're scared of jail. They hear things like that all the time. Unless you have been deemed unable to work, you need to be out there supporting your kids, or you'll go to jail. I'm not judging you, only telling you what I have experienced.
I wish you the best.
