Well, there is no presumptive means of "undoing" an adoption, which was probably preceded by a formal Termination of Parental Rights, although you do not mention those proceedings. About the only way you could possibly proceed, absent cooperation of the other parties, is to file an action to set aside the termination (and therefore the adoption) for fraud, coercion, duress, etc. On the facts as you have set them out, this would be an uphill battle. You should probably take all of your paperwork to a full consultation with a family law specialist to go over all the facts and circumstances and determine whether you have a possible case to make.
