Pled not guilty to charge
Criminal Defense Attorney
I do not practice in CO but i would recommend that you contact a competent criminal defense attorney in your area for a consultation. In general, errors like this are not fatal and the court will allow defects to be corrected. But your local criminal rules and/or case law may provide a basis to make a motion to dismiss. Don't ignore the summons, get counsel and follow his/her advice.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
