If you live in Sycamore and are starting a divorce, your case is filed and heard at the DeKalb County Courthouse at 133 West State Street, the historic limestone building in the heart of downtown Sycamore. Because Sycamore is the county seat, residents do not travel out of town to file. The Circuit Clerk's office on the second floor processes every dissolution of marriage for the county, and DeKalb sits within the 23rd Judicial Circuit alongside Kendall County. This page explains where Sycamore residents file, what it costs, how long it takes, and which Illinois statutes control the outcome.

How do I file for divorce in Sycamore, Illinois?
To file for divorce in Sycamore, one spouse must have lived in Illinois at least 90 days before judgment under 750 ILCS 5/401, then e-file a Petition for Dissolution of Marriage with the DeKalb County Circuit Clerk and pay roughly $337-$388. Illinois is pure no-fault, so the only ground is irreconcilable differences. E-filing has been mandatory for civil cases statewide since 2018, so most filers create an account with an approved e-filing service provider before submitting.
The practical sequence in Sycamore looks like this. First, confirm the residency requirement is met (only one spouse needs the 90 days). Second, prepare the petition plus any summons and, if children are involved, a proposed parenting plan, which 750 ILCS 5/602.10 requires within 120 days of filing. Third, e-file through a provider listed on the Illinois Courts site, since paper filing is now the exception. Fourth, serve your spouse, unless they sign an Entry of Appearance and Waiver. The Circuit Clerk at 133 W. State St. assigns your case number and routes it to a 23rd Circuit judge who handles family matters.
Where do I file for divorce in Sycamore? (which courthouse)
Sycamore divorce cases are filed with the DeKalb County Circuit Clerk at the DeKalb County Courthouse, 133 West State Street, Sycamore, IL 60178, on the second floor. The civil and divorce phone line is 815-895-7131, and the clerk's hours are 8:30 a.m. to 4:30 p.m. Because Sycamore is the county seat, this is the only courthouse where DeKalb County dissolutions are heard.
Do not confuse the Circuit Clerk with the County Clerk and Recorder. The Circuit Clerk, where you file your divorce, is inside the courthouse at 133 W. State St. The County Clerk and Recorder, a separate office that issues marriage licenses and records deeds, sits a few blocks away at 110 East Sycamore Street, phone 815-895-7149. Filers heading downtown will find public parking lots within two blocks of the courthouse. Even though e-filing is mandatory, the clerk's counter remains the place to resolve fee questions, request a fee-waiver application, or get certified copies once your judgment is entered.
How much does a divorce lawyer cost in Sycamore?
A Sycamore divorce lawyer typically charges $250-$400 per hour, with uncontested cases often handled on flat fees of roughly $1,500-$3,500 and contested cases running $7,000-$15,000 or more depending on disputes over property and parenting. Separately, the DeKalb County Circuit Clerk charges a filing fee of approximately $337-$388, set by the county fee schedule last revised October 1, 2025.
Several factors push Sycamore legal costs up or down. An uncontested divorce where both spouses agree on property division, support, and a parenting plan keeps attorney hours low. Disputes that require discovery, business valuations, or a guardian ad litem for the children raise the total quickly. Court costs beyond the initial filing fee can include fees for motions, certified copies, and service of process. If you cannot afford the filing fee, Illinois lets you submit an Application for Waiver of Court Fees (the indigency application), which a 23rd Circuit judge can grant in full or in part.

How long does a divorce take in Sycamore?
An uncontested Sycamore divorce can conclude in about 2 to 4 months once the 90-day residency requirement under 750 ILCS 5/401 is satisfied and both spouses sign a marital settlement agreement. Contested cases in DeKalb County commonly take 9 to 18 months, and complex disputes over property or parenting can extend beyond two years.
Illinois has no mandatory pre-filing waiting period and no statutory cooling-off period between filing and judgment. The often-cited six months is not a waiting period at all. Under 750 ILCS 5/401(a-5), living separate and apart for a continuous six months before judgment creates an irrebuttable presumption that irreconcilable differences exist. In an uncontested case, both spouses can waive that six-month showing by agreement, which is why cooperative Sycamore couples sometimes finish in a single short hearing. What actually drives the timeline is the level of conflict: agreement on the parenting plan, the equitable split of marital property, and support is what lets a 23rd Circuit judge enter judgment fastest.
What are the residency requirements to file in DeKalb County?
To divorce in DeKalb County, at least one spouse must have resided in Illinois for 90 days immediately preceding entry of judgment, under 750 ILCS 5/401(a). Only one spouse needs to meet this. The requirement is jurisdictional, so a 23rd Circuit judge cannot finalize the divorce until it is satisfied, though you may file the petition before the 90 days are complete.
The residency rule is about Illinois residency, not specifically Sycamore or DeKalb County residency, so a spouse who recently moved to Sycamore but has lived elsewhere in Illinois for over 90 days still qualifies. Active-duty military stationed in Illinois for at least 90 days are treated as residents even when their legal domicile is another state. Because residency is a jurisdictional mandate, the parties cannot waive or shorten it by agreement; a judge will dismiss a petition filed without it. Venue in DeKalb County is proper when a spouse resides in the county, which is why Sycamore residents file at 133 W. State St. rather than in a neighboring circuit.
How is property divided in a Sycamore divorce?
Illinois divides marital property by equitable distribution under 750 ILCS 5/503, meaning a DeKalb County judge splits assets and debts in just proportions, not automatically 50/50. The court first assigns each spouse their non-marital property, then weighs twelve statutory factors, including the length of the marriage, each spouse's economic circumstances, and contributions as a homemaker.
Under 750 ILCS 5/503(b), property acquired by either spouse during the marriage is presumed marital, and any doubt about whether an asset is marital must be resolved in favor of finding it marital. Non-marital property generally includes inheritances, gifts to one spouse, and assets owned before the marriage, along with anything exchanged for them. Pensions, stock options, and restricted stock earned during the marriage are presumed marital, often divided through a Qualified Illinois Domestic Relations Order. Assets are usually valued as of the divorce trial date or another agreed date. For couples in Sycamore with a home, retirement accounts, or business interests, the equitable framework means the fair result depends on the specific facts, which is why documentation of separate property matters.
How does Illinois handle child custody for Sycamore parents?
Illinois replaced the word custody with the allocation of parental responsibilities under 750 ILCS 5/602.5 and 5/602.7. A DeKalb County judge allocates decision-making authority and parenting time according to the child's best interests, presuming both parents are fit and not restricting parenting time unless a parent shows by a preponderance of evidence that it would seriously endanger the child.
Under 750 ILCS 5/602.7(b), the court weighs factors such as each parent's caretaking during the prior 24 months, the child's wishes given the child's maturity, the child's adjustment to home, school, and community, and the distance between the parents' homes. Sycamore parents who agree can submit a joint parenting plan; if they cannot agree, each must file a proposed plan within 120 days under 750 ILCS 5/602.10. The statute bars the court from considering parental conduct that does not affect the parent-child relationship, and it provides substitute parenting time for a parent deployed in the U.S. Armed Forces.
