Parents are living apart a while ago, now my school is asking me for stuff

<p>Hi, my dad and my step mom were having a lot of drama and they have been living apart for about 8 months now. I filled my fafsa and just put my dad and i in our household. however, my school is asking me for a proof of their divorse or separation... well, here's the thing they have not done anything about it because they think they might go back in the future, and they filled their taxes separated (since their fights where always about money) my dad as head of household with me as a dependent, and she as single. I talked to my school and they said there was no problem, but since they didn't have something to actually proof that they are living apart (she lives with her dad, and all her bills and stuff has my apartment's address, except her taxes; she put her dad's address) i had to put them both in my fafsa (this time through a verification sheet). So, i am wondering, if i do this, will they have any problems with the IRS because they filled their taxes that way, and now fafsa will appear as like they are part of the same household?</p>
