How We Handle Divorce

We Handle Every Type of
Divorce Situation

Divorce is rarely just paperwork. It touches the house, the kids, the retirement accounts, and the next ten years of your life. We help you understand what's actually at stake, what your realistic options look like, and what the path forward could be, before any decisions are made. You leave the first conversation with a plan, not more anxiety.

How Long Does Divorce Take in Illinois?

Every divorce is different. Some uncontested divorces can be resolved in a matter of months, while contested cases involving children, finances, businesses, or complex assets may take significantly longer. During your consultation, we'll explain the factors that affect your timeline and provide realistic expectations based on your specific circumstances.

How Much Does Divorce Cost?

The cost of divorce depends on the level of conflict, the complexity of the issues involved, and whether agreements can be reached outside of court. During your consultation, we'll discuss potential costs, explain what drives legal expenses, and help you understand strategies that may reduce unnecessary fees while protecting your interests.

What Will Happen to My Children, Home, and Finances?

This is often the biggest concern people have when considering divorce. Illinois law provides a framework for addressing parenting responsibilities, support, property division, and financial matters, but every family is unique. We help you understand your options, identify potential risks, and develop a strategy focused on protecting what matters most to you.

Here's How We Handle
Divorce Cases

Most people have never been through a divorce before. The uncertainty can feel overwhelming. Our role is to explain where you are in the process, what decisions are coming, and what your options are at every stage. The goal is fewer surprises, better preparation, and more confidence moving forward.

The First Conversation

Filing & Initial Disclosures

Reaching Agreement

Going to Court (If Needed)

After the Judgment

1. The First Conversation

We start with a full conversation about your situation: what you know, what you don't, what you want, and what you're worried about. We review the basics of your finances, your parenting situation if children are involved, and any immediate concerns like safety or asset protection. By the end of the consultation, you'll know whether your case is likely contested or uncontested, what the realistic timeline looks like, and what working with us actually costs.

2. Filing & Initial Disclosures

Once you decide to move forward, we draft and file the Petition for Dissolution of Marriage, serve your spouse (or accept service if they're cooperating), and prepare your initial financial disclosures. Illinois requires both parties to exchange a Financial Affidavit and supporting documents like tax returns and pay stubs early in the case. We handle the procedural deadlines so you do not have to track them.

3. Reaching Agreement

Most Illinois divorces resolve here, before any trial. We negotiate directly with your spouse's attorney on property division, parenting time, support, and the other major terms, and we attend mediation when issues require a neutral third party. In Cook County, mediation is mandatory for parenting disputes (Cir. Ct. R. 13.4). When we reach agreement, we draft the Marital Settlement Agreement and any Parental Allocation Judgment for the court to enter.

4. Going to Court (If Needed)

When the parties cannot reach agreement on one or more issues, the court decides. We represent you at status hearings, evidentiary hearings on specific motions, and ultimately at trial if the case requires it. Trial preparation includes formal discovery, outside professionals where appropriate (forensic accountants, custody evaluators, business valuators), and clear, organized arguments tailored to the judge assigned to your case. The court then enters a Judgment of Dissolution based on the evidence presented.

5. After the Judgment

Once the Judgment of Dissolution is entered, the divorce is legally complete, but the work often is not. We handle Qualified Domestic Relations Orders (QDROs) for retirement accounts, deed transfers for real estate, and any cleanup motions needed to finalize the financial division. Down the road, we also handle post-decree modifications when circumstances change, like a job loss, a relocation, or a parenting schedule that is no longer working.

Working With Us

Here's What You Can Count On

Family law cases run long. The right working relationship matters as much as the right legal strategy. These are the standards we hold ourselves to, every day, from your first call through your final order.

Communication Standard

We respond to every client message within one business day, often the same day. When your attorney is in court, the team responds first so you always know we have heard you.

Who Makes The Decisions

We explain your options in plain English, give you our recommendation, and tell you the tradeoffs. We never settle, file a motion, or commit you to anything without your written authorization.

Billing Transparency

Every invoice is itemized so you see exactly what we did and what it cost. If a strategic choice will add meaningful cost, we tell you before we do the work.

Documentation Rhythm

After every hearing, negotiation, or strategic decision, you get a written summary of what happened, what was decided, and what comes next. You always have a record to re-read when the moment is calmer.

What People Actually Ask Us About Illinois Divorce

These are the questions we hear most often from people who are thinking about filing for divorce in Illinois, or who have just been served. If yours is not here, send it over to us.

Does Illinois Require Grounds to File for Divorce?

No. Illinois is a no-fault state, which means you don't have to prove your spouse did something wrong to get divorced. The legal standard is irreconcilable differences, and once the parties have lived separate and apart for at least six months (which can include living in the same home but apart as roommates), the court presumes the marriage is broken beyond repair.

What's the Difference Between Contested and Uncontested Divorce?

An uncontested divorce means both spouses agree on every major term: property division, parenting time, child support, maintenance, and the rest. A contested divorce means at least one of those issues needs to be negotiated or decided by a judge. Uncontested cases finalize faster and cost less; contested cases require more attorney involvement and sometimes a trial.

Will My Spouse and I Need to Live Separately Before We File?

No. Illinois requires that you've lived separate and apart for at least six months before the court presumes irreconcilable differences, but this can include living in the same home as functionally separate households. You don't need to move out to file. Many spouses stay in the home through the process for financial or parenting reasons.

How Is Property Divided in an Illinois Divorce?

Illinois follows equitable distribution laws. This means marital property is divided fairly, but not necessarily equally. Courts consider factors such as the length of the marriage, contributions of each spouse, income, future earning capacity, and other circumstances when determining division of assets and debts.

How Is Child Custody Determined in Illinois?

Illinois courts make parenting decisions based on the best interests of the child. Factors may include the child's relationship with each parent, each parent's ability to provide care, the child's needs, and each parent's willingness to support the child's relationship with the other parent.

Will I Have to Go to Court During My Divorce?

Not always. Many divorce matters are resolved through negotiation, settlement discussions, or mediation. However, if major disagreements cannot be resolved, court hearings may be necessary. Our goal is to help clients reach favorable resolutions as efficiently as possible.

Reviews

Trusted During Difficult Times

Real clients on what it's like to have us in their corner.

"I have had the pleasure of knowing and working with Attorney Olivia St. Clair Long for almost a decade. I cannot say enough positive things about her as a person, how she practices law, and her character. I team up with her so I do not have to go against her, and her work is second to none! While Olivia will fight hard for her clients, she is also able to switch over to settlement mode with the same tenacity and in the interests of gaining the legal relief her clients request. Being in her field of law is quite emotional. I am impressed at how compassionate Olivia is with her clients, especially given the high stress matters she is retained therein"
"I had an excellent experience working with the team at O. Long Law, during a very challenging time in my life. The attorneys and paralegals were knowledgeable, compassionate, and always took the time to explain every step of the divorce process clearly. They handled my case with professionalism and made me feel confident that my best interests were being protected. Communication was consistent and timely, which helped reduce a lot of my stress. I would highly recommend this firm to anyone in need of reliable and supportive legal representation."
"Jessica was my representing attorney for my prenup. After being initially intimidated by the idea of a prenup, I felt comfortable talking with her. She is amazingly intelligent and personable. She went line-by-line through the draft prenup, explained everything to me, and made edits based on my feedback. She even thought ahead on things that I wouldn’t have even considered. I would recommend her to any of my friends needing representation."
"Olivia gave me advice in a high-conflict divorce situation - pro bono publico- and offered sound, clear and loving guidance. It was so clear to me that she is infinitely knowledgable and clear-headed. Strongly recommend. If you are part of a queer family, recommendation is even stronger, though I'm certain she'd represent everyone with care and honor."
