We took legal custody of my wife's biological niece in August of 2022. We have sole legal custody of her right now in California and our proof source is a notarized, signed paper from her grandmother, giving us custody to take her across state lines. I have heard about the 180-day sleep law, and we had her in 2022 for a total of 101 days. My main question aside from her family in Montana, are we allowed to claim her as a dependent of our household for the 2022 tax year or would we need to wait until 2023?
I can provide more details and proof if needed. Thank you for your attention and time!
