Unfortunately, this happens quite a bit. If you continue to not get overtime, you can wait a few months, then file a Supplemental Petition and attempt to modify the amount of child support you are require to pay based on your new lower net income.
If the order was entered in the last 10 days, it may be possible to file a motion for rehearing. I suggest that you retain an attorney to assist you with this.
If it is more than 10 days but less than 30 days, there is the possibility of an appeal, however, it seems very unlikely that an unrepresented person is going to be able to successfully prosecute an appeal, particularly if that person was unable to have the trial court correctly determine income, which would seem to be a much simpler task. Hiring an attorney for an appeal is likely to cost thousands of dollars and probably would not have a great likelihood of success.
If it is more than 30 days, then I would agree with my colleague and wait at least six months and then bring proof on the overtime issue, including having a live witness, such as your direct supervisor or a higher up in your company.
For advice specific to your situation, consult with an experienced family law attorney in your area, bringing a copy of the child support order with you. Many attorneys offer a free initial consultation.
