@MoralDelemma Actually, the irony could be that they “think that they are gaming the system” and have screwed around with her residency AND get in trouble for that for nothing. They would have had to fill out two types forms for their private school (there are a couple exceptions), the FASFA and the CSS profile so the schools know the income and assets of both parents. The schools don’t care about their marriage status or the legal custody status, they just want to know what you can pay and the schools must know this. That would actually be sad if they get caught for changing her residency when it didn’t even matter.
