Only if:1) the divorce settlement, agreement, decree, or order stated that it would increase as your income increased, or at least that it could be revisited on that basis--generally, there is no increase if the paying ex-spouse does better economically, but it would be legal if the potential for an increase had been put in place when the support was ordered; or2) it can be shown that you committed fraud (knowingly lied about) your income, job, economic prospects, etc. when the original maintenance was set--in that case, the fraud could void the original agreement and leave it open to be re-determined.
