I claimed my niece on my taxes and it was rejected... help!
I currently have custody of my niece. She lived with me from the end of December 2009 until the beginning of May 2010. In October of 2010 she was given to me from CPS (now officially a foster child). I claimed her on my taxes and it was rejected because someone had claimed her already. My brother (who had 100% custody, the mother has 0%) knows I was claiming her. Is there anything I can do? I don't think I can fight it because I can't prove she was with me in the beginning of the year.
