Been paying c/s for years now but not enough according to the courts
I have been been paying $550 month and health care costs to the mother of my 11 year old son since he was born and we never had paternity established or any court order to pay. This was simply a verbal agreement to pay that amount. I have now been granted guardianship over my son and he is nearing the age that he can state a preference and if he goes back to live with his mother, the state will determine that I owe $1150 per month in child support. Can they also go back and collect support from those years that I only paid $550? If so, how far back can they go? We did not have paternity established for those years but do now.
