It is possible, but not necessarily guaranteed, that you can get an increase in child support or maintenance payments if your ex gets a raise. When a divorced spouse receives a substantial raise, it can be considered a “change in circumstance” and can be grounds for modifying the original order. At least when it comes to child support, this typically requires you to show a change of at least 10% in the amount of support that would be due to be granted the modification or continuing, meaning it isn’t a one-time bonus or payment.
