If you have questioned whether you need to have an attorney, the answer is more likely yes.
There are many reasons to hire an attorney. Even if you do not intend to have a jury trial and fight the case, having an attorney on your side can be invaluable. The consequences of facing criminal charges and having a criminal record can last a lifetime. An attorney can help investigate the facts of the case, to determine whether they meet the elements of a criminal offense and advise you accordingly.
Even if you believe that you are guilty, an attorney can assist in negotiating a resolution for your case that would be in your best interest. There may be options to resolve your case that you may not be aware of, and an experienced criminal defense attorney can help explore those options.
