See who would get the most money back thin go from there and you should see if he can file the both of you just put you as disabled.
Me and my sons father has this "discussion" EVERY tax season...One thing you can do is maybe try to file together, another thing... i've never done this and don't know if it is allowed, you can go to H&R Block they will do your taxes with out filing and see how much you will get, and you decide if it is worth it for you to file, or him... you will have way less chance of owing if you claim a child and also my childs father tried that i'll give you half thing but one thing i'm worried about is I have medical insurance and everything for my child if someone else claims him will it mess with that because it's me on his papers. My other view point I say to him is the child lives with me, I provide most the care and until you do the same I will get it and we don't split it ,also taxes you get back is part of taxes you paid out of your hard earned money claiming the child does not give you "money" it gives you that much of a deduction because of the expenses a child has. If he paid money to you as support he can claim that money and get a deduction for that while you claim her, and both get off with a somewhat "child" deduction Good Luck to you!
I know it's long but I hope it's somewhat helpful. (And also I don't give him the ss card or birth certificate, if he wants to push that hard to claim he can go through everythign to get them, mine always backs down lol).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
