Thank you for your question

Do you mean will your child maintenance liability change?
I am afraid that your ex's position does not impact your child maintenance at all - she could marry a millionaire (or become one) and it would not change your liability.
Just to check - you should not be paying any more than 16% of your gross income - details here
Please ask if you need further details
