How we match your Oak Park family law case

When you submit a Oak Park family law matter, we route it through a national network of independent partner firms and put it in front of the one that fits best — based on the kind of case it is, what it is likely to involve, where it has to be handled, and who has capacity to take it on now.

Case type

A family law matter needs someone who handles family law work day to day, not a generalist. Practice area is the first filter.

Size and complexity

Some firms are built for catastrophic injury and multi-party litigation; others resolve straightforward claims quickly. We weigh what your matter is likely to involve against how each firm actually works.

Jurisdiction and licensing

Your matter is decided under Illinois law, so it goes to an attorney licensed in Illinois who regularly appears where your case would be heard.

Capacity and fit

Availability, conflicts of interest and language all matter. If the best-fit firm cannot take your case, we route it to the next one that can — or tell you plainly when no one in the network is the right answer.

Every partner reviews your case for free. Injury and workers’ compensation matters are handled on contingency — no fee unless you win. Other matters are quoted upfront, before you commit to anything.

Family Law matters in Illinois are usually a flat fee per filing — quoted before you commit, not billed by the hour.

Family law cases in Illinois are not handled on contingency. Illinois Rule of Professional Conduct 1.5(d)(1) — patterned on ABA Model Rule 1.5(d) — prohibits contingent fees in domestic relations matters where the fee is contingent on securing a divorce or on the amount of maintenance, support, or property settlement. Illinois family law attorneys charge hourly (billed against a retainer) or a flat fee for uncontested matters. Courts may award fees under 750 ILCS 5/501(c-1) and 5/503(j).

Divorce is filed in the Circuit Court of Cook County, in the division that handles domestic relations matters, and suburban cases are often heard at the district courthouse serving this part of the county. Residency requirements apply. An attorney will confirm the right courthouse and whether Illinois is the proper state for your filing.

Illinois divides marital property equitably, which means fairly given the circumstances rather than automatically in half, and separate property acquired before marriage may be treated differently. Child support uses an income-sharing calculation based on both parents' incomes and parenting time. Accurate financial disclosure drives both results.

Illinois has procedural timing rules for divorce and for responding once you are served, and other family matters carry their own windows. These vary by case type and situation. Have an Illinois attorney confirm the deadlines that apply to you rather than relying on a general figure.

Illinois has no mandatory waiting period (since 2016). Uncontested divorces typically finalize 60–120 days after filing. Contested cases generally take 9–18 months, with high-conflict cases extending well beyond.

Yes — and as of 2016, no-fault is the only basis for divorce in Illinois. Irreconcilable differences must be established under 750 ILCS 5/401, which the parties can prove by 6 months of separation (presumed) or stipulation.
