You filed a life insurance claim after someone close to you died. Instead of a check, you got questions — or a letter saying the insurer is investigating the application. Now you’re hearing the phrase “contestability period” for the first time, and you need to understand what it means for your claim.
The contestability period is the window — typically two years from when a policy takes effect — during which an insurer can review the original application and deny a claim if it finds errors that mattered. After that window closes, the insurer largely loses the right to second-guess what the policyholder wrote. This article explains how contestability works in Illinois, what insurers look for, and what you can do if your claim is denied.
What Is the Contestability Period?
How long does it last?
Two years from the date the policy was issued. During this time, the insurer can review the application and look for wrong or missing information. After two years, the policy becomes what insurers call “incontestable” — the insurer generally cannot deny a claim based on application errors.
What does the insurer look for?
The insurer compares what the policyholder wrote on the application to what the records show. They pull medical records, prescription history, and sometimes financial documents. The goal is to find a “material misrepresentation” — a statement that was wrong and that would have changed the insurer’s decision to issue the policy. If the error was significant enough, the insurer can deny the claim or rescind the policy entirely.
The most common issues insurers flag:
- Tobacco use. Smoker rates run two to three times higher than non-smoker rates, so applicants have a strong incentive to understate tobacco use. Insurers detect discrepancies through nicotine metabolites in blood or urine tests and through medical records that document smoking status.
- Pre-existing medical conditions. Undisclosed diagnoses of heart disease, diabetes, cancer, high blood pressure, or high cholesterol. Even conditions the applicant considered “controlled” can become the basis for a denial.
- Prescription medications. Insurers check prescription databases. Undisclosed medications often reveal undisclosed conditions — cardiac drugs suggest heart problems, psychiatric medications suggest mental health history.
- Alcohol or substance use. Past treatment or a diagnosis of alcohol dependence can be flagged if not disclosed, even if the applicant was in recovery at the time of application.
- Family medical history. Heart disease or cancer in immediate family members affects underwriting decisions.
- Hazardous activities. Skydiving, racing, or high-risk occupations that weren’t disclosed.
Does the period restart if the policy changes?
Often, yes. If the policyholder raised the death benefit, converted a term policy to whole life, or reinstated a lapsed policy, the two-year clock may start over. Each of these changes typically requires new health questions, giving the insurer a fresh contestability window. Illinois courts read life insurance policies as integrated contracts — each provision matters. Rich v. Principal Life Ins. Co., 226 Ill. 2d 359 (2007). Check the reinstatement or conversion language in your specific policy.
What Counts as a Material Misrepresentation?
What does “material” mean?
A misrepresentation is “material” if it would have changed the insurer’s decision. If the policyholder had cancer and didn’t disclose it, then died of cancer 18 months later, that omission is almost certainly material. But a minor error — like listing the wrong address for a doctor’s office — usually is not. The test is whether the insurer would have declined the application or charged a higher premium had it known the truth.
Who has to prove materiality?
The insurer does. Under Illinois law, the insurer bears the burden of proving any exclusion or defense. Once you establish that the policy existed and the death occurred, the insurer must prove the misrepresentation actually changed its underwriting decision. They cannot simply point to an error — they must show it mattered.
Can an honest mistake lead to a denial?
Yes. Intent is not required for a misrepresentation to be material. Even an innocent error can justify a denial if the omitted fact would have changed the insurer’s decision. But there is a distinction between an honest mistake and fraud. Fraud requires intentional deception — and that distinction matters, because fraud may allow the insurer to contest a policy even after the two-year period ends.
How Do Insurers Investigate During the Contestability Period?
What does the investigation involve?
The insurer requests medical records, pharmacy records, and sometimes motor vehicle or financial records. They compare every answer on the application to what the documentation shows. These investigations can take weeks or months. The insurer is not simply processing a claim — they are actively looking for grounds to deny it.
Does the insurer have to follow any rules?
Yes. Illinois law requires insurers to investigate promptly and, if they deny the claim, to provide a clear written explanation citing the specific policy language and alleged misrepresentation. Vague denials or unexplained delays may support a bad faith claim.
What Happens After the Two Years End?
Can the insurer still deny the claim?
Generally, no — at least not based on application errors. Once the contestability period closes, the insurer loses the right to rescind the policy over what the policyholder said on the application. This is one of the strongest protections a beneficiary has.
Are there exceptions?
Very few. Illinois’s incontestability statute is one of the strongest protections beneficiaries have. Once two years pass, the insurer generally cannot rescind the policy based on application errors — even deliberate ones. The statute’s exceptions are narrow: nonpayment of premiums, and certain provisions related to disability benefits, accidental death, military service, or aviation. Ordinary misrepresentation, even if intentional, does not survive the two-year period under Illinois law.
What if the death was unrelated to the misrepresentation?
This catches many families off guard. Suppose the policyholder failed to disclose high blood pressure but died in a car accident. The insurer may still argue the omission was material because it would have affected the premium or the decision to insure at all. Illinois law focuses on whether the error mattered to the underwriting decision — not whether it caused the death.
If the policy’s contestability language is ambiguous, Illinois law favors coverage. Under the contra proferentem doctrine, unclear terms are construed against the insurer who drafted the policy. Hobbs v. Hartford Ins. Co., 214 Ill. 2d 11 (2005).
What Should You Do After a Contestability Denial?
Start with the denial letter. It should identify the specific policy provision and the exact misrepresentation the insurer is relying on. If the letter is vague, that itself may violate Illinois regulations.
From there:
- Request the full claim file from the insurer
- Compare the alleged misrepresentation to the actual application and medical records
- Check the timeline — how long did the insurer take to investigate and respond?
- Confirm that the two-year contestability window hasn’t already closed
If the insurer’s conduct was vexatious and unreasonable, you may be entitled to attorney fees and statutory sanctions under 215 ILCS 5/155. A denial is not the final word.
Frequently Asked Questions
Does the contestability period apply to group life insurance through work?
Yes, but the timing works differently. Group policies typically have the same two-year window, but it runs from when you enrolled or when your coverage amount changed — not from when your employer first purchased the plan. If your employer switched carriers, the new insurer may have a fresh contestability period.
One important caveat: many employer-sponsored group life policies are governed by federal ERISA law, which changes the available remedies. If your claim involves a group policy through work, ask an attorney whether ERISA applies.
What if the death was a suicide?
Life insurance policies typically have a separate suicide clause in addition to the general contestability provision. Under Illinois insurance regulations, the suicide exclusion period cannot exceed the contestability period — meaning it caps at two years. 50 Ill. Admin. Code 1405.40(f).
If the death occurred within the suicide exclusion period, the insurer may deny the death benefit but typically must return the premiums paid. Some policies use a one-year exclusion, others two. The suicide clause operates independently of the misrepresentation rules — a completely truthful application won’t help if the death falls within the exclusion window.
What if the policyholder told the truth on the application?
The insurer still has the right to investigate during the contestability period, but they should not find a basis to deny. If the investigation confirms the application was accurate, the insurer must pay the claim. A thorough investigation that turns up nothing is not a valid reason to delay payment.
Can you file a complaint with the Illinois Department of Insurance?
Yes. If you believe the insurer is stalling or wrongly denying your claim, you can file a complaint with the Illinois DOI online at no cost.
