Top 3 Qualities to look for in Your Attorney

Watch Our Video

We believe your attorney should not speak in legalese

Finding an attorney who is a “real person” can be difficult. Many attorneys surround themselves almost exclusively with other attorneys and are accustomed to speaking in ivory tower legalese.  You should be able to connect with your attorney on a personal level, and he or she should speak to you in plain language that you can understand.  You will be working very closely with this person on issues that are very important to you. It is important that he or she be down-to-earth and someone that you connect with.

We believe your attorney should be accessible

The most common complaint that clients have of their attorneys is that the attorney is unreachable, does not communicate with them regularly, or does not promptly return your calls.  Your attorney should reach out to you about your case regularly and respond within 24 hours to calls and e-mails.  An open line of communication between you and your attorney is essential to building trust.

We believe your attorney should be realistic with you about costs and outcomes

Your attorney’s goal should not be to win at all costs.  Rather, it should be to achieve a favorable outcome for you as efficiently as possible.  It is important that your attorney set realistic expectations at the outset as to the costs you should expect, the concerns that the attorney has about the outcome of your case, and the length of time that you should expect your case to take.

Regardless of the nature of your case, we have an experienced attorney who will focus on your individual needs. Our team of attorneys works closely together, bringing each of their different fields of experience to bear in order to optimize our client care.

Get Defense Against Statutory Summary Suspension Of Your License

In this articel, our Cook County defense attorneys discuss the various ways your license can be suspended along with the length of time each specific suspension could last. For example, If you refuse a breathalyzer for your first DUI, this will result in an automatic one-year suspension, and a breathalyzer reading a BAC higher than .08 will also result in an automatic license suspension, but this suspension typically lasts 3 to 6 months. 

it's important to know you have the right to a hearing even if your license is suspended.  If you fail to file a Petition for Hearing within 90 days of your arrest, your right to a hearing will be waived.  Within 30 days of the filing date you will receive a date for your hearing. During this hearing, some questions to expect are:

  • Did the officer have probable cause to pull you over?
  • Did you receive the proper legally required statutory summary suspension warnings? 
  • Was a proper arrest made? 
  • Did you actually fail the breathalyzer?

See What Qualifies as an Aggravated DUI in Illinois

In this article, our Cook County criminal defense lawyer explains the penalties for DUI in Cook County. When faced with a DUI, there are important points you need to know. 

  • If you receive a DUI, it's possible the charges can be reduced or dismissed 
  • If the court allows neither, supervision is possible which enables you to keep your licenses along with a conviction off your record

The caveat to this is that you are required to complete everything the court requests in regards to their terms for supervision. This could include alcohol evaluations and classes in addition to fines that can be a condition to receiving court supervision.  If you are granted court supervision, your case will be dismissed once supervision and all court requirements are met, usually in up to 12 months.  

After a second DUI, circumstances become more difficult and you lose any eligibility for court supervision and the revocation of your license is a certainty.  Charges escalate exponentially, if you a repeat offender and it is crucial to know that receiving a third DUI is considered a felony in the state of Illinois.  If you're faced with one or more DUI's it is imperative to have an experienced and skilled attorney to fight for your rights.  Our Cook County DUI attorneys will give your case the attention and detail it vitally needs to put you in the best position to overcome charges against you.
