Illinois SOS Form DSD SR 81 Security Deposit Guide – If you were involved in a motor vehicle crash in Illinois without liability insurance, the Illinois Secretary of State may require you to post a security deposit to protect your driving privileges. Form DSD SR 81 (also known as DSD SR-81) is the official document used to submit that security deposit under Section 7-205 of the Illinois Safety Responsibility Law.
This guide explains what Form DSD SR 81 is, when you need it, how to complete it correctly, acceptable payment methods, mailing instructions, and what happens after you submit it. All information is based on official Illinois Secretary of State publications and the Illinois Vehicle Code.
What Is Illinois Form DSD SR 81?
Form DSD SR 81 is the official Security Deposit form issued by the Illinois Office of the Secretary of State, Driver Services Department. It is used when a driver or vehicle owner must deposit security (money or a surety bond) after an uninsured crash as required by the Illinois Safety Responsibility Law (625 ILCS 5/Chapter 7).
The security deposit acts as a financial guarantee that any potential civil judgment for damages from the crash can be paid. Depositing security is not an admission of fault or guilt. The amount is determined by the Illinois Department of Transportation based on reported damages.
You can download the official current version of the form (DSD SR-81.4) directly from the Illinois Secretary of State:

When Do You Need Form DSD SR 81?
You typically receive a notice from the Illinois Secretary of State if:
- You were involved in a crash while uninsured (or underinsured).
- The Illinois Department of Transportation determined that a security deposit is required.
- The Secretary of State finds a reasonable possibility of a civil judgment against you.
Under 625 ILCS 5/7-205, the Secretary of State mails a notice stating that your driving privileges, driver’s license, or vehicle registration will be suspended 45 days after the mailing date unless you deposit the required security or request a formal hearing within 15 days.
Common alternatives to posting a security deposit include:
- Filing a notarized release or covenant not to sue from the damaged party.
- Entering a notarized installment agreement.
- Providing proof of insurance that was in effect at the time of the crash.
If none of these apply, Form DSD SR 81 is the way to post the security and avoid or lift the suspension.
How to Complete Form DSD SR 81 Step by Step?
The form must be completed fully and accurately. Incomplete forms cause delays.
- Vehicle Operator Information – Enter the complete name of the vehicle operator, date of birth, full address (including 9-digit ZIP code), driver’s license number, date of the crash, and accident number (if known).
- Amount of Deposit – Write the exact dollar amount required. The check or money order must be made payable to the “Secretary of State’s office.”
- Method of Payment – Check one of the accepted methods:
- Money order
- Bank draft
- Certified check
- Cashier’s check
Important: Personal uncertified checks are not accepted.
- Coverage of Operator and Owner – Indicate whether the security deposit covers the operator involved in the crash (Yes/No) and the owner involved in the crash (Yes/No).
- Receipt Recipient – Print the complete name of the person to whom the security deposit receipt should be issued.
- Signature and Date – The depositor must sign and date the form.
Always include your driver’s license number, full name, and date of birth on the form.
Accepted Forms of Security and Payment Rules
According to Illinois administrative rules (92 Ill. Adm. Code 1070.10), the Secretary of State accepts:
- Certified checks
- Money orders
- Bank drafts
- Cashier’s checks
- Cash
- Surety bonds (from companies authorized to do business in Illinois)
The amount of security is set by the Illinois Department of Transportation and cannot exceed the limits in Section 7-203 of the Illinois Vehicle Code. The person depositing the security must specify on the form on whose behalf the deposit is made.
All deposits must be sent to:
Illinois Secretary of State
Driver Services Department
Safety Responsibility Section
2701 S. Dirksen Parkway
Springfield, IL 62723
Security is not considered deposited until it is received at this address in an acceptable form.
Processing Time and Checking Your Status
Allow approximately 10 working days for the office to process a security deposit. If you are also submitting an SR-22 Certificate of Insurance, allow 10 to 20 working days.
You can check the status of your driver’s license 24 hours a day by calling the automated attendant at 217-782-3720 and selecting option 1. You will need your driver’s license number and Social Security number. The system will tell you if your privileges are valid or still suspended.
Once your record shows as valid, you may drive. A confirmation letter is mailed to you by U.S. Mail.
Important Notes About SR-22 Requirements
If you post the security deposit after the suspension date, you must also file Proof of Financial Responsibility in the form of an SR-22 Certificate of Insurance. The SR-22 must be filed directly by an authorized insurance company and maintained for 36 months. Failure to keep the insurance in force results in an immediate driver’s license suspension.
Contact your insurance agent promptly if an SR-22 is required.
What Happens After You Deposit Security?
Once the security is accepted:
- The Secretary of State notifies the damaged party (claimant).
- The claimant may claim the funds through agreement (Method 1) or by filing a civil lawsuit (Method 2). See official Form DSD SR 91 for claiming procedures.
- You may later request a refund of the security under certain conditions (for example, after the statute of limitations expires and no lawsuit was filed) using Form DSD SR 89 – Affidavit for Refund of Security Deposited.
