As indicated, earlier in this thread, the court order (dated before 2009), must be without conditions ( usually the payment of child support). The IRS will not accept a curt order, with conditions, even if you are in compliance.
If that is the case, yes you can file an amended return, attaching copies of the relevant pages of the court order, including the first page and the signature page.
Another issue is how old is the child. That is, is a 2005 court order still valid, if the child has reached the age of emancipation.
