Yes, it is possible that the order may be modified: courts can and do change support obligations if the person paying can demonstrate that due to some life change beyond his or her control, he or she cannot meet the obligation anymore. Being unemployed two years may well be enough to justify such a change, if your ex-spouse can demonstrate that he has been trying to find work, but cannot due to changes in the economy or job market, which, given the circumstances, is certainly plausible.Look at it this way: it does you no good to have an order for support which he simply cannot pay; all the court orders in the world cannot make him have money if he doesn't have any. If his situation is legitimate, you don't really lose anything from a modifcation of his support to something he can in fact pay. If his income goes up, you in turn can later look to have a higher level of support reinstated.
