<human>: Can you give me the gist of the text in a nutshell?

Several months ago, my wife and I had a large fight which resulted in my expulsion from the home via restraining order for 10 weeks. I have since resolved (most) of the issues with my wife, but one thing continues to plague both of us.

While I was out of the home, she filed the necessary paperwork to begin receiving benefits from the State. This included CalWorks, a cash benefit, as well as CalFresh, effectively food stamps. She also is receiving assistance for tuition and books at school.

When she signed up for everything, she truthfully advised the social worker that we had 2 kids, and that she was making zero income. The benefits she is receiving were calculated based on those figures. 

Now that I am back home, she is terrified that she is going to get into trouble for taking unauthorized benefits. She told them as soon as I moved back in that I was there, but at the time, we were still working out what would happen with out relationship, and I moved back in purely to avoid having to pay rent at two locations. Nesting is the term, I believe. 

To this day, our relationship is still strained, and we still fight. So much so that she has expressed to me that she still has moments of doubt about where we are going. That is something for /r/relationships though. What I'm wondering is what kind of trouble she could get in to, if any? She has admitted to the social worker that I am back in the house, but I don't know if she formally filed any paperwork alerting them to the change in status. The circumstances regarding our relationship are the same now as they were then: I live there, and we are amicable, but we are more roommates than partners.
<bot>: My wife started receiving benefits while I was kicked out of the house, and now I've moved back in. The State was informed, but took no action at the time. What kind of trouble could she get into?
