Using Surveillance Footage in Slip and Fall Injury Cases

Security cameras are everywhere in Chicago. They line the walls of Magnificent Mile shops, hang in the corridors of River North hotels, monitor the aisles of grocery stores in Lincoln Park, and sweep the parking garages beneath Millennium Park. When you slip and fall on someone else’s property, that footage may be the single most powerful piece of evidence you have. It can show exactly what caused your fall, how long the hazard existed, and whether anyone on staff knew about it. Understanding how surveillance footage works in a Chicago slip and fall case, and how to protect it, could make or break your claim.

Why Surveillance Footage Matters in a Slip and Fall Case

A slip and fall case comes down to proof. Under the Illinois Premises Liability Act (740 ILCS 130/2), a property owner must exercise reasonable care to protect people lawfully on their property from conditions that could cause injury. Proving that a property owner failed to meet that standard requires solid evidence, and surveillance footage is often the clearest form of it.

Think about a common scenario. You slip on a wet floor inside a Chicago convenience store on North Michigan Avenue. You know the floor was wet. The store manager says an employee mopped just minutes before you fell. Those two stories conflict. But a security camera pointed at that aisle tells the truth. It shows when the floor was last mopped, whether a wet floor sign was placed, and how many customers walked through that area before you fell. That footage can establish whether the store had constructive notice of the hazard, meaning the condition existed long enough that the owner reasonably should have discovered and fixed it.

Surveillance video can also capture details that witnesses miss or misremember. It shows the exact angle of your fall, the lighting conditions at the time, whether any warning signs were present, and the reactions of nearby employees. As a Chicago slip and fall lawyer reviews your case, this footage often becomes the foundation of the entire legal theory.

Beyond establishing what happened, video evidence can also counter arguments that you were at fault. Under 735 ILCS 5/2-1116, Illinois follows a modified comparative negligence rule. If a court finds you more than 50% responsible for your own injuries, you recover nothing. If your share of fault is 50% or less, your damages are reduced proportionally. Surveillance footage showing that a hazard was obvious, or that you were walking carefully and still fell, can directly reduce any blame placed on you.

How to Preserve Surveillance Footage After a Fall

Speed matters more than almost anything else after a slip and fall in Chicago. Most commercial security systems overwrite their footage on a rolling basis, often within 24 to 72 hours. Some larger systems store footage for up to 30 days, but that is not guaranteed. Once footage is overwritten, it is gone forever. You cannot recreate it, and no amount of legal effort will bring it back.

The moment you are physically able, you or someone you trust should take steps to request that footage be preserved. You can do this in writing, directly to the property owner or manager. A written request creates a record that you asked for the footage, which becomes important if it later disappears. Courts in Illinois take the loss of evidence seriously. Under the spoliation doctrine recognized in Boyd v. Travelers Insurance Co., 166 Ill. 2d 188 (1995), a duty to preserve evidence can arise through a special circumstance or voluntary undertaking. If a property owner is on notice that footage is relevant to a potential claim and allows it to be deleted anyway, that decision can carry legal consequences.

The Illinois Supreme Court in Dardeen v. Kuehling, 213 Ill. 2d 329 (2004), established a two-prong test for spoliation claims. First, there must be a relationship or circumstance that creates a duty to preserve. Second, a reasonable person in the defendant’s position must have foreseen that the evidence would be material to a civil action. When a person falls and reports the incident to management, both prongs are often satisfied. The property owner knows an injury occurred and knows a camera may have captured it. Deleting that footage after receiving notice of a claim can result in sanctions, adverse jury instructions, or other penalties under Illinois Supreme Court Rule 219(c).

Contacting an experienced slip and fall attorney as soon as possible after your accident gives you the best chance of sending a formal preservation demand before the footage is gone. An attorney can send that demand immediately and, if necessary, seek a court order compelling the property owner to hand over the recording.

What Surveillance Footage Can and Cannot Prove

Surveillance footage is powerful, but it is not a guaranteed win. Understanding what it can and cannot show helps you set realistic expectations for your case.

On the positive side, video can show the condition of the floor, stairs, or surface at the time of your fall. It can reveal whether a hazard like a spill, loose mat, or broken tile was visible well before you arrived. It can show whether employees walked past the hazard without addressing it, which directly supports a constructive notice argument. In cases involving poorly lit hallways, broken stairs, or greasy surfaces in Chicago restaurants and retail stores, footage often confirms that the dangerous condition was exactly as you described it.

Video can also identify witnesses. People standing nearby when you fell may appear on camera. Their presence can be used to locate them and obtain witness statements, adding another layer of evidence to your claim.

That said, camera angles matter. A camera positioned at the wrong angle may not capture the hazard itself, only your fall. In that situation, the footage shows that you fell but does not show why. This is where other evidence, such as incident reports, maintenance logs, and employee testimony, must fill the gap. A slip and fall lawyer will work to combine all available evidence into a coherent picture of negligence.

For footage to be admissible in Illinois courts, it must meet certain standards. The video must be relevant to a disputed fact in the case. It must be authenticated, meaning someone must confirm it has not been altered or tampered with. And it must have been obtained lawfully. Recording in public areas of commercial properties generally complies with Illinois law, but footage gathered through unlawful means may be excluded. Your attorney will ensure that any video evidence presented meets the requirements for admissibility.

Sending a Spoliation Letter and Taking Legal Action

A spoliation letter is a formal written demand telling a property owner or business to preserve all evidence related to your accident, including surveillance footage. It puts the recipient on clear legal notice that the footage is material to a potential civil claim. Once that letter is received, the property owner’s obligation to preserve the footage becomes much harder to dispute.

Illinois courts have recognized that when a party allows evidence to be destroyed after receiving notice of a potential claim, the court may instruct the jury to draw an adverse inference. That means the jury can assume the destroyed footage would have been unfavorable to the property owner. This is a significant consequence. In a contested slip and fall case before a Cook County judge, an adverse inference instruction can shift the entire dynamic of the trial.

Beyond the adverse inference, courts can impose other sanctions for spoliation, including barring the offending party from presenting certain defenses or even entering a default judgment in extreme cases. The Illinois State Bar Association has recognized that sanctions for spoliation serve both to punish the party who destroyed evidence and to remedy the harm caused to the injured person who can no longer access that proof.

A spoliation letter should be sent immediately after an accident, ideally within 24 to 48 hours. It should specifically identify the date, time, and location of the fall, request that all surveillance footage from that day be preserved, and demand that the footage not be overwritten, deleted, or altered. The letter should also request preservation of maintenance logs, cleaning records, and any incident reports, since those documents work alongside video evidence to establish what the property owner knew and when they knew it.

If you were injured in a fall at a CTA station, a Wicker Park retail shop, a South Loop parking garage, or anywhere else in the Chicago area, Briskman Briskman & Greenberg can send that preservation demand on your behalf right away. The sooner you reach out, the better your chances of securing the footage before it disappears.

How Briskman Briskman & Greenberg Uses Surveillance Evidence

Building a strong slip and fall case in Chicago requires more than just pointing to a video clip. It requires connecting that footage to the legal elements of negligence under Illinois premises liability law. At Briskman Briskman & Greenberg, every case involving surveillance footage is approached with a detailed investigation strategy designed to extract the full value of that evidence.

The process starts with identifying every possible camera that could have captured the incident or the conditions leading up to it. In a large facility like a Chicago shopping mall or a Loop office building, multiple cameras may cover the same area from different angles. Footage from adjacent cameras can show how long a hazard existed before you arrived, which is critical for proving constructive notice.

Once footage is secured, it is reviewed carefully alongside other evidence, including cleaning logs, employee schedules, maintenance records, and incident reports. When surveillance confirms that employees walked past a spill multiple times without addressing it, that combination of evidence can be extremely compelling to a jury or an insurance adjuster.

Illinois law under 735 ILCS 5/2-1117 holds that all defendants found liable are jointly and severally liable for a plaintiff’s past and future medical expenses. This matters when multiple parties, such as a property owner and a maintenance company, share responsibility for the unsafe condition. Footage that shows the condition existed over an extended period can help establish that responsibility spans more than one defendant.

If you or someone you love was injured in a slip and fall anywhere in Chicago, from the Gold Coast to Bridgeport to Englewood, do not wait. Contact Briskman Briskman & Greenberg today for a free consultation with a Chicago personal injury lawyer who will act quickly to preserve the evidence your case depends on. You can also speak with a dedicated slip and fall attorney who understands what it takes to build a winning case under Illinois law. Time is short, and the footage will not wait.

FAQs About Using Surveillance Footage in Slip and Fall Injury Cases

How long do businesses in Chicago typically keep surveillance footage?

Most commercial businesses overwrite their security camera footage within 24 to 72 hours, though some larger facilities store it for up to 30 days. There is no universal Illinois law requiring a specific retention period for general security footage. This is why acting immediately after a slip and fall is so important. Once the footage is overwritten, it cannot be recovered, and your ability to prove what happened becomes significantly harder.

Can a property owner delete surveillance footage after I report my fall?

Deleting footage after receiving notice of a potential claim can expose a property owner to serious legal consequences in Illinois. Under the spoliation doctrine established in Boyd v. Travelers Insurance Co. and refined in Dardeen v. Kuehling, a duty to preserve evidence can arise when a property owner knows an injury occurred and reasonably should foresee that the footage is material to a civil action. If they destroy it anyway, a court may sanction them, instruct the jury to draw a negative inference, or bar certain defenses.

What if the camera angle did not capture the hazard that caused my fall?

An unfavorable camera angle does not automatically sink your case. Even footage that shows only your fall, not the hazard itself, can still be useful. It can confirm the time and location of the incident, show the absence of warning signs, and identify witnesses who were nearby. Your attorney will pair the video with other evidence such as maintenance logs, employee testimony, and incident reports to build a complete picture of what happened and why the property owner is liable.

Does Illinois law allow surveillance footage as evidence in court?

Yes. Illinois courts permit video recordings as evidence as long as they meet the requirements for admissibility. The footage must be relevant to a disputed fact in the case, it must be authenticated to confirm it has not been altered, and it must have been obtained lawfully. Security camera footage from commercial properties, which are generally accessible to the public, typically satisfies these requirements. Your attorney will handle the process of obtaining and authenticating the footage for use in your case.

How does comparative negligence affect a slip and fall case where surveillance footage exists?

Under 735 ILCS 5/2-1116, Illinois uses a modified comparative negligence rule. If a court finds you more than 50% at fault for your own injuries, you cannot recover any damages. If your fault is 50% or less, your damages are reduced by your percentage of responsibility. Surveillance footage can directly affect this calculation. If the video shows you were walking carefully and the hazard was not obvious, it can minimize any finding of fault on your part. On the other hand, footage showing distracted behavior could be used against you, which is why having an attorney review the video before the other side does is so important.
