My husbands ex(one night stand) fights with us every year about who claims their daughter on taxes. She does not work and he pays over half the child support. She has a live in boyfriend who thinks that he can claim her. My husband has never signed any papers on this topic and neither has she. But, to my understanding, she does not work and therefore has nothing to file. He, (ex's boyfriend) collects unemployment(not sure of guidelines on filing taxes) but has no rights to their daughter. My husband is in the military and only sees his daughter a few times a year, if that. Its not his choice, its his job. Anyway, she seems to think that just because the child lives with them, that her boyfriend can legally claim her on his taxes... Does anyone know the guidelines on this subject or know how I can find out? Thanks.
