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.

Filing Paternity Suits in Chicago

In this article, our Chicago paternity attorneys explain the types of paternity cases that  three different primary types of paternity cases that can be filed in Chicago.We discuss who can file a paternity suit, when can a contested paternity suit be filed and how the courts proceed with these matters. We also discuss contested paternity suits as well as the statute of limitations regarding these types of cases. There are several causes of action in Illinois related to paternity, including:

  • Establishing paternity by consent of the parents;
  • Contested paternity suits; and
  • Suits to establish the non-existence of a father-child relationship.

Illinois provides that certain forms must be presented to non-married parents at the hospital upon the birth of a child, which allow the parents to facilitate establishing paternity by mutual consent.  These forms include:

  • An agreed order to establish paternity by consent, and reserve issues of child support until a later date; and
  • A verified petition to declare paternity.

A paternity suit to establish the existence of a father-child relationship can be filed by the mother, the child, anyone claiming to be the child's father, any person or agency with custody of the child,  or any person or agency providing financial assistance to the child.

Voluntary Acknowledgement of Paternity in Chicago

In this article, our Chicago paternity lawyers explain the establishment of paternity by consent at birth. When children born to patents who are unmarried, hospitals and midwives are required by the Illinois Vital Records Act to provide the parents with the forms that allow the parents to simply and easily establish paternity by mutual consent, assuming that both parents agree.  These forms include:

  • A petition to declare paternity by consent; and
  • An agreed order to be entered by the court in which the petition is filed, which will establish paternity.
  • If the parents are in agreement about paternity, they can execute these forms and deliver them to the clerk of the circuit court.  The judge will then enter the agreed order without requiring the parents to appear in court.
