The short answer is that you will need to show a material change in circumstances warranting a modification of alimony. Just because your ex's income has gone up does not mean that you are entitled to a modification, nor the fact that things cost more. It will also depend on the language of your Agreement or Judgment regarding possible future modification of alimony, as well as increasing costs, etc. You will at the very least have to prepare a new matrimonial Case Information Statement and submit it, together with the CIS from the original divorce, showing that your expenses have increased, what your income is, etc. I suggest that you speak with a matrimonial attorney about the basis for an increase in your alimony.
