my wife and I were separated when I caught her cheating. She moved out of the house we owned and established her own residency. During this time, nearly a year, she paid nothing to the mortgage, bills etc. At tax time she filed separately and claimed both my son and the house. I got stuck with IRS bills over $4,000. on top of that she cleaned out the account I had to pay taxes. how can she get away with claiming the house on her taxes when she doesn't live there nor pay any bills.
