So my ex has been on child support for 3 years now and I just got a paper for declaration of change in circumstances but I didn't contact them for any changes for myself so I'm assuming my ex did but why did they send me this paper to fill out if I'm not making the changes myself? Do they just automatically send them to both parties? I've never had to make changes or anything so I'm not sure how it works.. I figured he was going to get ahold of child support because he was trying to get me to stop the child support because he said he can't afford it (it's $215 a month and has been the whole time)...
