What is the Application for Adjustment of Claim?
In Illinois, to formally initiate a workers’ compensation case, you must file a specific document called the Application for Adjustment of Claim. While it is commonly referred to as a “lawsuit,” it is technically a petition filed under the Illinois Workers’ Compensation Act.
As Jack Epstein warns, while it is possible to do this yourself, it is a complicated legal process. If you have legal questions about the severity of your injury or the validity of your claim, it is always advisable to consult a qualified lawyer who understands the complexities of the Illinois Workers’ Compensation Commission (IWCC).
Steps to Complete Your Application
To fill out the form correctly, you must follow these essential steps:
- Get the Form: You can find the IC01 form on the official Commission website (www.iwcc.il.gov) under the “Case Management Forms” section.
- Identify the Type of Case: Mark whether your case falls under the Workers’ Compensation Act (common accidents like fractures or back injuries) or the Occupational Diseases Act (such as asbestosis).
- Party Information: You must include your full name (Petitioner) and the exact legal name of your employer (Respondent).
- Accident Details: State the exact date, location (city and state), and a brief description of how the accident occurred (e.g., “forklift accident”).
- Nature of the Injury: Jack Epstein recommends describing the injury as “permanent and severe” to ensure the true impact of the damage is recognized.
The Challenge of the Average Weekly Wage (AWW)
One of the most critical and difficult fields to complete is your Average Weekly Wage (AWW). This number determines how much you will receive in temporary disability benefits.
Calculating this can be deceptive, as factors like overtime, bonuses, and tips can all affect the final figure. An error in this calculation could mean you receive significantly less money than you are legally owed.
How to File the Document
Once the application is completed, the final process includes:
- Signature and Notarization: You must sign the document and have it notarized to verify that the information is correct.
- Proof of Service: You must complete the second page of the form, certifying that you have sent a copy of the application to your employer.
- In-Person Filing: Jack Epstein recommends taking six copies of the document directly to the Commission office (100 West Randolph, 8th Floor, Chicago) to have them officially file-stamped.
Expert Insight: The Long-Term Commitment
“Filing the application is just the beginning. Once you have a case open, you’ll have to appear at the Commission every three months to represent yourself. It is a long, complex process that requires constant attention.” — Jack Epstein
Jack Epstein, with 30 years of experience in the Illinois legal market, emphasizes that filing on your own means you are responsible for all future court dates and legal paperwork.
