Illinois Legal Considerations for Roommates
Understanding Illinois's legal framework helps you create a stronger roommate agreement and know your rights.
Important: Joint and Several Liability in Illinois
In Illinois, if all roommates are on the lease, each roommate is jointly and severally liable for the full rent amount. This means the landlord can pursue ANY roommate for the ENTIRE rent, not just their share. A roommate agreement establishes internal obligations so you can recover from a non-paying roommate in small claims court.
- Contract Enforceability: Illinois courts enforce written roommate agreements as valid contracts between private parties
- Small Claims Court: Illinois's small claims court handles disputes up to $10,000, covering most roommate disagreements
- Security Deposits: The landlord holds one deposit for the entire unit — your roommate agreement should document each person's share
- Lease vs. Agreement: Your roommate agreement does not modify the lease — it governs internal arrangements between co-tenants only
