Diamond & LeSueur is a local, well-established law firm with experienced and compassionate attorneys who will listen to you, will explain things in a way that you can understand, and who will aggressively represent you and fight for your rights.

At Diamond & LeSueur, we understand that when a marriage is ending it is much more than a separation of 2 people. It is a separation of families and friends, finances, possessions, property, lifestyle, dreams for the future and more. With such important decisions to be made, it is crucial that you retain an attorney who listens to you and has a clear understanding of your needs and goals.

Our legal team can assist you with a wide range of family law cases, including:

Child custody
Child support
Enforcement actions
Post decree modifications
Prenuptial agreements
Parent's rights and more.

Overwhelmed? Intimidated? Scared? Confused? Depressed? Angry?

It is natural to experience these feelings. Family law issues are emotional in nature and sorting through these complex and critical issues can be painful as well as intricate. Your attorney is your ally, friend and legal advocate, and selecting the right lawyer will make a world of difference in the outcome of your divorce. That's why it is important to select a divorce attorney with experience who also has empathy for what you're going through.

We provide you with the guidance and support needed to resolve family law issues using our decades of family law experience. The last few years saw big changes in Illinois family law and our legal team is engaged in continuing education so that we are up to date on changes in the laws.

Are you looking for an attorney who speaks "legalese" and won't listen to you?

Of course you aren't looking for an attorney like that, but they do exist. Communication is an art. We take the time to really listen to what you have to say. We will ask you about your personal and financial goals and help you create a plan to achieve them, while protecting your rights and interests along the way. Clear communication is vital in family law and we pride ourselves in being able to explain your case, your options and the entire process in a way you can understand.

If you are ready to take the next step, let us put our 40+ years of experience in family law to work for you!

Our philosophy for divorce and family law clients is to first address the needs of our clients. At the same time, we use common sense and practical techniques to minimize legal fees. Whenever possible, we encourage parties to cooperate and try to work out a settlement. Simply put, dissolution of marriage in many cases is similar to the dissolution of any other partnership. First, there needs to be a complete disclosure of all matters. Next, there needs to be a proposed settlement. A majority of the time in family law is spent in these negotiations by the attorneys. While litigation involves a dispute between parties, we encourage cooperation and communication between parties. With cooperation and communication we can get the results you want more quickly and with less expense.

However, sometimes, peaceful negotiation isn't enough. When your case calls for aggressive representation of your rights, you need lawyers who will passionately defend your interests and who have intimate knowledge of the court system in McHenry and Lake Counties Our legal team includes family lawyers who are skilled in negotiation, Illinois divorce law, and trial law. From simple uncontested matters to complex cases that are headed to the courtroom, our attorneys are ready to serve you and get you the closure you are looking for.

We encourage you to meet our team and ask us questions about our long-established family law practice here in Northern Illinois. Contact us today for a free consultation.


We first focus on helping struggling homeowners understand all of their options such as: loan modifications, short sales, or staying in the property as long as possible. We then help our clients create a strategy that suits their needs.

There are many options available to assist struggling homeowners including, but not limited to, loan modifications, short sales or staying in the property as long as possible. Unfortunately, some of these options take many months to pursue and many lenders do not stop foreclosure proceedings just because you are attempting one of these options. This is why it is important for you to be aware of all of your options as early as possible in this process.

We know and understand that anybody going through this process feels a tremendous amount of stress and pressure. We help to alleviate this stress and pressure by outlining all of their options and helping them formulate a customized plan to follow the path of least resistance to reach their goals. We also offer to continue guiding our clients through the foreclosure process to help them stay focused on the path towards relief.

Many of our clients facing foreclosure feel quite relieved after they have reviewed the various options with us. Call us today to arrange a free 30-minute initial consultation and take control of your future.
