It seems to me that it is first going to depend on exactly what the divorce decree and related documents actually say about the pension. The exact wording can have a significant affect upon how the risks of gain or loss are distributed between the two of you. Second, it is going to depend upon exactly why the money has disappeared, if it has. For example, if the pension plan administrator foolishly had all of the pension money invested in Enron before it collapsed, then, you may be out of luck. On the other hand, if the money has disappeared because your ex is hiding it somewhere, you may be able to collect something. Regardless, you are probably going to need to hire an attorney if you want to try to collect, because there may be significant issues of what you can prove or can't prove.
