I know this is a controversial subject but this is how it should be.
As long as the non custodial parent provides the court ordered child support he/she should be able to claim the child(ren) as dependents every other year, it should alternate with the custodial parent. The non custodial shouldn't have to have permission from the custodial parent since then it is solely up to the custodial parent. The court should make it as a alternating thing (as long as child support is being paid), the child is still a dependent to the non custodial parent since they are paying child support. This should be made into the child support order, an agreement. BOTH are taking care of the child(ren) so both should be able to file the child(ren).
No I am not a step parent, I myself have a daughter with my ex and I have to give him permission to file my daughter. I believe what I posted, my daughters father's child support order should have included his right to claim her as a dependent every other year. We both are paying to raise her so we both should be able to file. This is a flaw in the system that should be fixed.
I know a few bitter old hags will only see the title and become keyboard warriors but maybe a few educated women will actually read it and understand what I mean.
