You don't need for CSE to be on your order. The agency is there to collect child support on behalf of custodial parents and in many states at the request of the NCP if they don't want disputes whether they paid or not. If he is not paying, you can file your own contempt motion through family court at your time and expense. Or you can go through CSE. There are downsides to CSE such as they tend to be slower about getting things moving because they are more thorough about information gathering and they have large caseloads and they can also mess things up (this probably varies by area), but they also have enforcement powers at hand so can garnish wages, tax returns, get licenses (driving, business, professional, etc.) suspended, etc. I'm not suggesting that you do go through CSE at this time, just letting you know you always have that option, it's not something that has to be in your CO.
