Not to my knowledge. To err on the side of caution, I researched the issue a bit, and, unfortunately, didn't locate anything. Part of the problem, I would suggest, is that these are two very separate and distinct areas of the law, that being tuition assistance and divorce. In other words, there isn't anything obvious that would address both.
As I suggested earlier, this is one of those situations where it will be at the discretion of the court as to how to rule. In the absence of clear language in your divorce agreement, the judge has the legal authority to rule either way.
If you think this is worth fighting over, then file a motion and bring the matter before the judge. If it isn't worth the hassle to you, then I suppose you should forget about it. There's no "wrong" answer here, it's a matter of what makes the most sense to you.
