I live in the state of Pennsylvania. We're trying to figure out how to file this year without breaking any laws. My fiancé lives with me and I have 3 children from a former marriage. My ex husband pays child support. I am unemployed therefore I don't file every year. Does my fiancé have a right to claim my children because we've lived together this year, or does my ex have a right to claim them? I intend on doing more research and making a few calls if necessary, but wanted to know if anyone had this similar experience or knows the answer. Thanks mamas!
