Yes, the judgment against them as reported to the credit bureau will not show the reason for eviction, only the fact thereof. Either this was apparently not the first time your daughter and SIL have had a loud argument, or the condition of the property on LL's inspection was such that the LL would rather get rid of them than keep them, rent-paying or not. Don't defend your kid, you know exactly who she is and how she acts, and if she were living right, she wouldn't need you to defend her. Why does she and your SIL need to have "loud arguments" at all? Why can't they resolve their issues without yelling and screaming? That's probably the crux of the problem.
