An injunction is a court order that tells someone to do something, or to stop doing something. In Illinois, injunctions are an equity remedy, meaning they are typically used when money alone will not fix the problem. In real life, this can look like stopping a transfer of property, preventing interference with a contract, preserving access to a business account, or freezing conduct that is causing ongoing damage.
Urgency matters, but so does precision.
If you are asking a judge to act fast, your request must be narrow, fact based, and supported by sworn evidence. Broad requests, vague fears, or delay can undermine even a serious claim.
Chicago has both state and federal options depending on the dispute. Many injunction cases in Cook County are handled as equity matters, which commonly fall within the court’s Chancery work. If you are not sure which court fits your situation, the safest move is to get counsel early, before your opponent changes the facts on the ground.

If the harm is happening now, timing and paperwork matter. Bring the key documents, a clear timeline, and any proof you can swear to. Request an emergency review so we can evaluate whether a TRO is realistic, what evidence is missing, and how to frame a narrow order the judge can sign.
What an injunction is, and what it is not
An injunction is designed to prevent future harm, not to punish past behavior. It is most useful when the threatened injury cannot be repaired later with money, or when waiting for a final judgment would make the case meaningless. Illinois injunction law is in the Code of Civil Procedure, Article XI, and it covers restraining orders and injunction requirements.

TRO, preliminary injunction, permanent injunction: the practical difference
Temporary restraining order (TRO) is the shortest term tool. It is meant to stabilize the situation until the court can hold a fuller hearing. Illinois law allows a TRO without notice only in limited circumstances, and it requires specific sworn facts showing immediate and irreparable injury before notice and a hearing can occur.

Judges expect a usable order.Illinois requires injunction and restraining orders to state reasons, be specific, and describe the acts restrained in reasonable detail. If your proposed order is vague, you are asking for a denial or a rewrite from the bench.

Preliminary injunction lasts longer than a TRO and is usually entered after notice and a hearing. Illinois law states that a court should not grant a preliminary injunction without notice of the time and place of the application to the adverse party.

What you must prove to get injunctive relief in Illinois
Illinois courts commonly focus on a few core elements for preliminary injunctive relief: a clear right or interest needing protection, no adequate remedy at law, irreparable harm without the injunction, and a reasonable likelihood of success on the merits. Courts may also consider how harms balance between the parties. You do not win an injunction by telling a good story. You win by proving these elements with facts.
Evidence beats conclusions.
Judges want dates, documents, screenshots, bank records, contracts, sworn statements, and specific conduct. Fear, suspicion, and broad accusations usually do not carry emergency motions.
In Cook County, the standard TRO form itself reflects these concepts by listing findings such as a clearly ascertainable right, a fair question of success, irreparable harm, and no adequate remedy, and it also anticipates a bond requirement and a set hearing date for the preliminary injunction.

How the process often works in Chicago and Cook County
Most injunction cases start with a lawsuit plus an emergency motion. That usually includes a complaint, a motion for TRO or preliminary injunction, sworn support (verified complaint or affidavit when required), and a proposed order the judge can sign. In Cook County, injunction matters are part of equity practice that is commonly handled through the court’s Chancery work. The filing location, judge assignment, notice method, and hearing schedule depend on the case type and the relief requested.
If you seek a TRO without notice, the burden is higher.Illinois law requires specific sworn facts showing immediate and irreparable injury before notice and a hearing can occur, and it expects a prompt path to a preliminary injunction hearing. In federal court, the comparable framework is Rule 65, which also addresses notice, sworn proof, and the court’s ability to require security.

What to gather before you talk to a Chicago injunction lawyer
Move fast, but do not move sloppy. Injunction requests live or die on proof. If you can show the court a clear right, a specific threat, and why waiting will cause harm that cannot be repaired later, you have a real shot. If you cannot, you risk spending money to get a narrow order, or no order at all.
Start building a file you can hand to counsel in one message. Think: what happened, when it happened, who did it, how you know, and what exact conduct must stop today.
Injunction evidence checklist
- A one page timeline with dates and locations in Chicago or Cook County
- Contracts, leases, promissory notes, emails, and text messages
- Screenshots, photos, recordings you can authenticate, and witness names
- Proof of harm already occurring, plus what will happen next if nothing changes
- Your proposed order language describing the exact acts to stop or require
Write your request as a list of actions, not emotions.
Instead of saying, “They are ruining my business,” say, “They are logging into the account, changing credentials, and moving funds on these dates.” Instead of saying, “I am afraid they will sell the property,” say, “They scheduled a transfer for this date and I have the closing email.” Judges can only order specific conduct, so give them something specific to order.
Risks, costs, and common reasons TROs get denied
Emergency relief is powerful, so courts police it closely. If the judge believes money damages would be enough, or believes you waited too long to claim an emergency, the request often fails. Another common problem is asking for an order that is too broad, unclear, or hard to enforce.
Be prepared for the court to require security. Illinois law allows the court to require a bond for a restraining order or preliminary injunction, and Cook County forms commonly include a bond line. If you are wrongfully granted relief, the bond issue can become a real cost factor.
Delay can destroy urgency.
If you knew about the problem for weeks, the judge may doubt “immediate” harm. If you have clean evidence and a clean timeline, you can still win, but you must explain the delay with facts.
Finally, remember that an injunction is not the right tool for every problem. If the dispute is really about money, or if the key facts are hotly disputed and require discovery, you may need a different early strategy such as an expedited hearing, agreed status quo order, or targeted preservation relief.
State court vs federal court in Chicago
Many injunction cases in Chicago stay in Illinois state court under the Code of Civil Procedure, especially disputes tied to Illinois contracts, Illinois property, or parties located in Cook County. Some cases belong in federal court in Chicago, such as disputes with federal jurisdiction or parties from different states with the required amount in controversy. Federal injunction practice is guided by Rule 65, which has detailed requirements for notice, the contents of orders, and security.
Choosing the wrong court can cost you your timing advantage.
If you are not sure whether your case belongs in state or federal court, do not guess. Your filing decision can affect hearing speed, service rules, and the standard the judge applies at the first appearance.
If you need immediate action, ask counsel to evaluate jurisdiction, venue, and the fastest legitimate path to a hearing, including whether notice is required and what sworn proof is needed.
Already served with an injunction motion
Do not ignore it. Injunction hearings can move quickly. We can assess the request, challenge weak proof, and prepare a response that protects your options and reduces risk of an overly broad order.
