Child support is nothing but a state program and just like any other state program you must enroll inside the program. Did you give anybody permission to enroll you inside this program or to even place child support on your consumer report? So now that we know that you physically didn't enroll inside the program nor gotten written consent from any corporation to place child support on your credit sounds to me like somebody stole your identity. Let's look at what Congress federal law has to say about the matter. 18USC 102AA aggravated identity theft offenses in general. However during and in relation to any felony violation and no merited in subsection C not only transferred processes or uses without lawful authority a means of identification of another person shot in addition to the punishment provided for such felony be sentenced to a term of imprisonment of two years. So now that we know that somebody stole your identity and used means of identification to enroll you inside a program without written consent and without your permission.
