To get a temporary custody agreement in Illinois, you file a petition for temporary allocation of parental responsibilities under 750 ILCS 5/603.5 in the circuit court handling your divorce or parentage case, serve the other parent, and ask a judge to set parenting time and decision-making authority under the child’s best-interests standard until a final judgment replaces the temporary order.1Illinois General Assembly. Illinois Code 750 ILCS 5/603.5 If there’s no open case yet, you’ll need to start one first. The order a judge signs is binding immediately and stays in force until the case ends or the parents settle.
What a Temporary Order Actually Decides
Illinois dropped the words “custody” and “visitation” in 2016. The law now splits what used to be custody into two parts: significant decision-making responsibility (education, health, religion, and extracurricular activities) and parenting time (the physical schedule). A temporary order addresses both. One parent can be given sole authority over all four decision-making areas, the areas can be divided between the parents, or the parents can be ordered to make those decisions jointly. The parenting time piece lays out a concrete calendar: weekdays, weekends, holidays, school breaks, pick-up and drop-off times, and transition locations.
Precision matters here. Language like “reasonable parenting time” invites fights. A schedule that names Thanksgiving, winter break, and spring break and assigns them on an alternating-year basis prevents the next round of motion practice.
Step 1: Open or Identify Your Case
A petition for a temporary order is filed inside an active case. If your divorce or parentage case is already pending, you file the petition as a motion in that case with the Clerk of the Circuit Court in the county where the case lives. If there is no case yet, you have to start one — either a dissolution of marriage or a standalone petition for allocation of parental responsibilities under 750 ILCS 5/601.2.2Illinois General Assembly. Illinois Code 750 ILCS 5/601.2 – Jurisdiction; Commencement of Proceeding
Jurisdiction turns on whether Illinois is the child’s “home state” under the Uniform Child-Custody Jurisdiction and Enforcement Act. That means the child lived in Illinois with a parent for at least six consecutive months immediately before the case was filed.3Illinois General Assembly. Illinois Code 750 ILCS 36 – Uniform Child-Custody Jurisdiction and Enforcement Act If the child recently moved to Illinois, home-state jurisdiction may rest with another state, and you need to work that out before anything else.
Step 2: Prepare the Petition and UCCJEA Affidavit
Illinois uses standardized statewide forms, available free on the Illinois Courts website.4Office of the Illinois Courts. Approved Statewide Standardized Forms The petition should identify both parents and the child, describe the current living arrangement, propose the parenting time schedule and decision-making allocation you want, and explain why the court needs to act before a final trial. Concrete reasons carry weight: keeping the child in a current school, maintaining access to a treating doctor, protecting an established daily routine. Vague accusations about the other parent do not.
Every custody filing must include a UCCJEA affidavit. This lists every address where the child has lived in the past five years, the dates at each address, and the names and current addresses of everyone who lived with the child during those periods. If the child is under five, the history covers the child’s entire life. Verify the dates against school records, leases, or utility bills before signing. An incomplete or wrong affidavit can delay or sink the case.
Beyond custody itself, the broader temporary-relief statute, 750 ILCS 5/501, lets you ask for related protections in the same petition: temporary child support, temporary maintenance, and a restraining order that bars the other parent from removing the child from Illinois for more than 14 days or from hiding marital assets.5Illinois General Assembly. Illinois Code 750 ILCS 5/501 – Temporary Relief
Step 3: Serve the Other Parent
Once you file, the other parent has to be served with the petition and a notice of hearing. Under Illinois Supreme Court Rule 11, the default is electronic service, either by email or through the state’s e-filing system. If the other parent has no email on file, service can be made in person, by leaving the documents at their residence with a household member at least 13 years old, or by U.S. mail.
Timing is set by local rule. In Cook County, personal service must happen at least two court days before the hearing, and mailed service at least five court days before. Other counties set their own windows, so check the local rules where the case is pending. Miss the deadline and the hearing gets reset.
Step 4: The Hearing and the Best-Interests Standard
If both parents agree on the terms, the court can enter the temporary order based on a written parenting plan the parents submit together, and no contested hearing is needed. If the parents disagree, each side presents evidence and the judge decides. Either way, the judge applies the same best-interests standard used for permanent orders, drawing on the factor lists in 750 ILCS 5/602.5 (decision-making) and 750 ILCS 5/602.7 (parenting time).6Illinois General Assembly. Illinois Code 750 ILCS 5/602.5 – Allocation of Parental Responsibilities: Decision-Making7Illinois General Assembly. Illinois Code 750 ILCS 5/602.7 – Allocation of Parental Responsibilities: Parenting Time
The factors that tend to move the needle for a temporary order:
- How much day-to-day caretaking each parent performed in the 24 months before the petition was filed (or since birth, for children under two).
- The child’s adjustment to home, school, and community.
- Each parent’s willingness to support the child’s relationship with the other parent.
- The distance between the two homes and whether the proposed schedule actually works logistically.
- Any history of domestic violence or abuse, or whether a parent lives with a convicted sex offender.
- The child’s own wishes, if the child is mature enough to express a reasoned preference.
For decision-making specifically, the judge also weighs the level of conflict between the parents and whether that conflict would undermine joint decision-making, each parent’s track record of participating in major decisions, and any prior agreements about how decisions would be made. Joint decision-making tends not to be ordered when the parents are in open conflict; it depends on cooperation that may not exist.
Once signed, the order is enforceable immediately. Both parents get copies and the order governs their conduct until a final judgment replaces it.
When You Need an Emergency Order
Standard temporary petitions take days or weeks to be heard. When a child is in immediate danger, a parent can ask for an ex parte emergency order, which a judge can sign without first notifying the other parent. The threshold is high. You generally need to show imminent harm — physical abuse, neglect, substance abuse creating unsafe conditions, or a credible risk the other parent will leave the state with the child — supported by evidence like medical records, police reports, DCFS records, or messages showing threats. A general assertion that the other parent is unfit will not get an emergency order.
If a judge grants one, it takes effect immediately. You then serve the other parent with the order and notice of a follow-up hearing, usually set within a couple of weeks. At that hearing, the other parent gets to respond and the judge decides whether to keep, modify, or dissolve the emergency order. An ex parte order that doesn’t get a prompt follow-up hearing does not stay alive long.
If You Can’t Afford the Filing Fee
Filing fees vary by county, and opening a new case costs more than filing a motion inside an existing one. If paying the fee is a hardship, you can apply for a fee waiver under 735 ILCS 5/5-105. You qualify automatically if you receive certain public benefits, including SNAP, TANF, or SSI. If you don’t receive those benefits, you can still apply by showing that paying the fees would create substantial hardship.
Asking for Temporary Child Support at the Same Time
A temporary custody order usually comes with a temporary child support order. The same petition under 750 ILCS 5/501 can request both. Illinois uses an income-shares calculation under 750 ILCS 5/505: both parents’ net incomes are combined to determine the child’s basic support obligation, and each parent’s share is set in proportion to their income.8Illinois Department of Healthcare and Family Services. Income Shares The calculation also pulls in the number of overnights each parent has under the parenting schedule, health insurance premiums, and work-related childcare costs.
Both parents must produce financial documentation — pay stubs, tax returns, bank statements. If one parent appears to be deliberately underemployed, the court can impute income based on earning capacity rather than actual earnings. Illinois updated its Schedule of Basic Obligations and Gross-to-Net Income Conversion Table effective March 20, 2026, so any calculations should use the current tables.
After the Order: Enforcement and Modification
A temporary order carries the full weight of a court mandate. If the other parent denies you your allocated time, you can file an enforcement petition under 750 ILCS 5/607.5.9Illinois General Assembly. Illinois Code 750 ILCS 5/607.5 The remedies include compensatory makeup parenting time of the same type and duration (to be made up within six months, or within a year for holidays), a formal finding of contempt (which carries fines and up to six months in jail), civil fines, reimbursement of expenses caused by the violation, a cash bond to guarantee future compliance, and mandatory parenting classes or counseling paid for by the non-complying parent. Except for good cause, the court must order the non-complying parent to pay the other side’s attorney’s fees — which alone makes casual violations expensive. When a violation rises to “parenting time abuse,” the court can also suspend the offending parent’s driver’s license.
Temporary orders can be changed, but not freely. The general standard requires both a substantial change in circumstances and a showing that modification serves the child’s best interests. Exceptions exist: the court can modify without a substantial change if the arrangement reflects how the parents have actually been operating for at least six months without objection, if the proposed change is minor, or if the original order was based on facts the court didn’t know. For decision-making modifications filed within the first two years of an order, the standard is stricter — affidavits must show the child’s present environment may seriously endanger the child’s physical, mental, moral, or emotional health. The burden of proof is preponderance of the evidence.
A Non-Court Alternative When Both Parents Agree
Not every temporary arrangement needs a court case. If both parents agree that a third person — commonly a grandparent — should care for the child for a limited period, Illinois allows a short-term guardianship under 755 ILCS 5/11-5.4 with no court involvement.10Illinois General Assembly. Illinois Code 755 ILCS 5/11-5.4 A parent appoints the short-term guardian in a written document signed before at least two adult witnesses, and the guardian signs too. The appointment lasts up to 365 days, or longer for a military parent on active duty (deployment plus 30 days).
The limit: if the child’s other parent is alive, locatable, and willing and able to care for the child, you cannot appoint a short-term guardian unless that other parent also signs. This tool works when parents cooperate; it is not a workaround for a custody dispute.
