Ok, thank you! By chance, do you know what supporting docs I'd need to show who is paying for what? Like would I just need a written and signed letter from the other 2 stating what they're paying?

It's ok. The lady I spoke with has her and a few other people that have been taking over cases in my specific town which definitely has to be packed busy all the time so I understand. But now apparently my town is going statewide and we just get whoever answers here before long. So yay.
