Child support

Depends on the judge. If this lawyer is familiar with that judge, he/she may be right. I can see a problem wiht your use of the term "supposed". According to who? What if your son is held back several years before graduation, does that change when he was "supposed" to graduate? I don't know. The court order's normal language is similar to what you state; it provides that support continues until the child is 18, but then will continue past the 18th birthday so long as he is continuing to work towards a high school diploma and then ends once the diploma is obtained or he is no longer working towards getting it (the language in the order is more precise, but that is basically what it means). I hope this helps?
