<prompt> Human: My fiances parents just took all their stuff in to get taxes done today, and have said they are claiming her. My fiance is also claiming herself on her taxes and has had it like that at her job all last year. She made about 15k total last year.She was 19 last year and a student with financial aid and was on their insurance all year, but all last year shes lived with me and her parents have provided none of her support. The only issue is, we never changed her address during this time. Her parents only claimed her so they could get extra money. Should they be doing allowed to or not?The only criteria that she doesnt meet is living with them over half the year, but her address was never officially changed anywhere.  <response>: She just files like normal, claiming herself. The IRS will mail a notice out to both parties saying hey, one of you goofed up whoever made the mistake needs to refile. So your fiance does nothing because shes in the right and IRS will eventually settle everything and fiance gets the refund.
