Okay my divorce decree says that I will be able to claim my kids every even year I can claim 2 while she claims 1 and every odd year I claim 1 now my son is 19 the question I have is that I have not claimed my kids on my taxes the last 4 or 5 years and now I want to claim them what do I do so I can go back the last 4 or 5 years the reason I didn't is because I was told that if I was in child support I could not claim them but my divorce degree does not say anything about that.
Thank you
