Sterling has its own court building, but it is not the Whiteside County seat, which surprises many people starting a divorce.

Morrison or Sterling: where your case is handled
Under 705 ILCS 35/1, Whiteside County belongs to the 14th Judicial Circuit, together with Rock Island, Henry and Mercer counties. The Illinois Courts directory lists one courthouse for the county, in Morrison. The Circuit Clerk, however, operates in two places, and judges hear cases in both.
Whiteside County Courthouse (main office)
200 East Knox Street, Morrison, IL 61270
Circuit Clerk: (815) 772-5188
General Division: (815) 772-5164
Child Support: (815) 772-5163
Sterling court building (satellite office)
101 East Third Street, Sterling, IL 61081
Phone: (815) 535-4530
Email: circuitclerk@whiteside.org
Circuit Clerk website
The county does not say on its website which location hears dissolution cases, so call the clerk before you go. On the Judici daily docket, a courtroom letter (A, B, C) means Morrison and a number (102, 108) means Sterling. Your summons or court order will show which courtroom your case is set in.
Illinois requires e-filing in civil cases, including divorces. Card payments are accepted at the Morrison office and online through Judici or Court Money.
Whiteside County filing fees
| Dissolution and legal separation (schedule revised 9/4/2026) | Amount |
|---|---|
| Petition for dissolution of marriage or legal separation | $319 |
| Appearance or answer by the other spouse | $194 |
| Non-contested filing | $513 |
The $513 non-contested amount equals the petition and appearance fees together. Check the Whiteside County civil fee schedule (PDF) before you file; the link name still mentions 2022, but the document inside carries the 2026 figures.
If paying would be a hardship, submit the statewide Application for Waiver of Court Fees. People on SNAP, SSI, TANF, AABD or General Assistance, or with income at or below 125% of the federal poverty level, usually qualify for a full waiver. A partial waiver can apply up to 200%.
14th Circuit rules for divorce cases
Part 9 of the 14th Circuit’s rules of practice (posted by Whiteside County as the 2017 local rules) covers dissolution, legal separation and parenting cases. Key points:
- Financial affidavit (9(b)): if you ask for property division, maintenance, child support or attorney fees, you file the Illinois Supreme Court financial affidavit with your first pleading, and update it if it becomes inaccurate.
- Face-to-face settlement conference (9(c)): spouses and their lawyers must meet in person, or by phone for good cause, to negotiate and narrow the disputed issues.
- Pretrial memorandum (9(d)): before a contested final hearing, the parties submit a joint pretrial memorandum. Before a contested parenting hearing, they submit a joint parenting plan with each side’s positions.
- Privacy (9(f)): dates of birth, Social Security numbers and driver’s license numbers go on a sealed Confidential Disclosure Statement, not in public pleadings.
- Parenting education (9(l)): in child custody cases, parents complete a four-hour program on parenting time, custody and their effect on children. Each county clerk keeps the list of approved programs, so ask the clerk for the current list and prices.
- Family mediation (9(m)): the judge must order mediation in any contested custody case unless an impediment exists, such as family violence. The referral comes within 90 days after the respondent is served. Mediators are paid by the parties, typically with a $500 retainer unless the court treats the case as reduced fee or pro bono.
For remote hearings, Whiteside County posts Zoom rooms for the Morrison and Sterling courtrooms. People who are in the courtroom are heard first, and Zoom cases can wait up to an hour. Attorneys appearing remotely in non-testimonial civil matters file a notice at least 48 hours ahead.

How to choose a divorce lawyer
A lawyer is optional, but advice helps when children, real estate, retirement accounts, a business or safety concerns are involved.
- Verify on ARDC. The Illinois ARDC lawyer search shows whether a lawyer is licensed and any public discipline.
- Ask about local practice. Do they regularly handle family cases in Morrison and Sterling, and do they know the 14th Circuit’s mediation and pretrial memorandum rules?
- Use the consultation well. Ask what result is realistic, whether mediation suits your case, who will do the work and at what rate, and what you can do to keep costs down.
- Compare fee structures. Hourly billing against a retainer is common in contested cases. A flat fee is sometimes offered for a defined job, such as an agreed divorce. Get the scope in writing.
- Read the client rights statement. Illinois law (750 ILCS 5/508(f)) requires it in every written divorce engagement agreement.
What the statement guarantees you: the lawyer “may not require a non-refundable retainer fee, but must remit back any overpayment at the end of the representation.” You also get itemized bills at least quarterly, and fees cannot depend on winning the divorce or on the support or property you receive, except as Supreme Court rules allow. If you change lawyers, your file must be turned over within 30 days.
Illinois rules in brief
- Residency: 90 days in Illinois (or military presence) by one spouse, under 750 ILCS 5/401.

- Maintenance: estimate it with the Illinois alimony calculator.
- Served with papers: the usual deadline to respond is 30 days. See what to do when served in Illinois.

Joint simplified dissolution
For short marriages with few assets, 750 ILCS 5/452 offers a simplified joint procedure. You must meet every condition: no children together and no pregnancy; married 8 years or less; no real estate; no retirement benefits except IRAs under $10,000 combined; both waive maintenance; net marital property under $50,000; combined gross income under $60,000 and neither spouse above $30,000; full disclosure of assets, debts and tax returns; and written agreements dividing assets over $100, debts and any companion animals. Both spouses appear in person, using forms from the circuit clerk (750 ILCS 5/453).
