I want to modify my final child support but i moved to another state. Like originally child support and custody was finalized in one state but after a year i moved to another state. I have been getting child support since then and its been 4 years. Now i believe my kids father income has increased so i want to file for increase in child support. And i do work full time.

Right now im in one state

Kids father is in another state

And final child support was filed completed in another 3rd state

So i wanted to ask do i have to go to state where child support was finalized to change it through court? Or can i file in the state im currently living?

Edit:

Yes i left the state as per the legal requirement and after taking ex husband permission in written form legally.

And yes i am working full time
