The first thirty days of an Illinois divorce are quieter than most people expect, but the decisions made in that window quietly shape everything that follows: temporary parenting time, who occupies the marital home, who pays which bills, and what the negotiating posture looks like six months out.
Day one: filing or being served
Cases begin with a Petition for Dissolution of Marriage filed in the circuit court of the county where one spouse resides. If you are the petitioner, you choose the timing — if you are the respondent, you have 30 days from being served to file your Appearance and Response. Missing that deadline can result in a default judgment.
Temporary relief — the parallel track
While the main case proceeds, either party can ask the court for temporary orders covering:
- Temporary parenting time — who the children are with, on what schedule, pending the final allocation judgment.
- Temporary maintenance and child support — guideline-based interim payments to keep both households running.
- Exclusive possession of the marital residence — when occupancy by both parties is no longer feasible.
- Restraining orders on marital assets — to prevent dissipation of accounts, sales of property, or transfers of business interests.
Temporary orders are not placeholders. They establish patterns judges hesitate to disrupt later. A reasonable temporary parenting schedule often becomes the de facto baseline for the final allocation judgment, even when the facts later support a different split.
Financial disclosure starts immediately
Illinois divorce requires a Financial Affidavit — a comprehensive sworn statement of income, expenses, assets, and liabilities. Most counties require it within 30 days of the case opening. Production of bank statements, tax returns, retirement account statements, and business records typically follows in the weeks after.
The early decisions that quietly matter
- Who files first. It’s mostly a procedural matter, but it can affect venue and the temporary-relief timeline.
- Who stays in the house. Move-out decisions are emotional but legally consequential — they affect possession and, in some counties, parenting-time inferences.
- Which accounts get separated. Joint accounts, joint cards, and bills in both names need a plan within the first few weeks.
- What you say to the kids, and when. Children become witnesses in disputed parenting cases more often than parents anticipate.
What we do in the first thirty days
When VF Law takes on a new family law matter, the first thirty days are about three things: stabilizing the immediate situation (parenting, finances, residence), gathering the financial picture, and setting the negotiating posture — whether that posture is collaborative, mediation-track, or trial-ready from day one.
If you’re considering a divorce, or you’ve already been served, the time to talk to counsel is now — not after the first temporary motion has been decided.
