Required to Report income change for Child Support?
2 attorney answers
send him a form to ask for his tax returns and for his last three pay stubs. This form does not need to have a hearing pending before the court. After you file a motion, you can do further discovery, and ask you a lot more, such as investment accounts.
Speak to an experience lawyer,
The court will not order retroactive child support as you are asking above.
However, I recommend you file a request for order to modify support. If his income has truly doubled as you state, and all other factors (time share of the children, your income, etc.) remain the same, the child support amount will likely be increased. The court can then order the new amount effective back to the date your request was filed.
So, the sooner you file your request, the better.
