How to sue your roommate in small claims court.
Unpaid rent, unpaid bills, moving out without notice, property damage, security-deposit disputes, and emotional distress. Roommate cases are textbook small-claims cases. Most settle once a demand letter arrives. Bank records, texts, and lease provisions establish the case.

How small claims handles roommate disputes.
Roommate disputes are textbook small-claims cases. Most state caps fall between $5,000 and $20,000. Most cases settle once a demand letter arrives. The lease, the bank records, and a string of payment-app messages do most of the work.

What can you recover?
The math judges use. A typical roommate case stacks the unpaid share, any damage or unpaid bills, and the filing fee.
Their portion of rent and shared bills you covered while they were on the lease.
Repair receipts, replacement cost, deep cleaning. Photos and dated receipts anchor the number.
Filing fee, service of process, pre-judgment interest at the state legal rate.
What evidence do you need to sue your roommate?
Roommate cases are won on the lease, the payment-app history, and the texts. Most evidence already lives on your phone. Pull it together before you draft the demand letter.
The lease
Every page of the signed lease, plus any roommate agreement or rent-split memo. Names on the lease set who is liable.
Bank and payment-app history
Venmo, Zelle, Cash App, bank transfers. Pattern of who paid what month builds the case faster than any document.
Texts and group chats
Anything where the roommate acknowledges the rent split, the missing payment, or the move-out plan. Screenshot whole threads.
Move-in and move-out photos
Date-stamped photos of the unit on day one and the day they moved out. Damage cases live or die here.
Replacement-roommate timeline
Listings, screening texts, and move-in date for whoever filled the room. Proves you mitigated the loss.
Witness statements
Other roommates, friends, or the landlord can confirm the split or the damage. A short signed declaration helps.
State-specific rules.
Joint-and-several liability rules, security-deposit rules, and contribution doctrines vary by state. Pick yours for the exact rules.

Can I sue my roommate in small claims court?
Yes. Unpaid rent, unpaid utilities, moving out without notice, property damage, security-deposit disputes, and emotional distress all support small-claims cases. Most cases settle once a demand letter arrives. Documentation is the spine: lease, bank records, texts, witness testimony.
What if there's no written lease or roommate agreement?
You can still sue. Courts will recognize an 'implied contract' based on how you actually behaved — months of consistent Venmo payments establish what the agreement was. Texts about money and witness testimony also help. It's harder to prove than a case with a written lease, but you can still win the same amount.
How long do I have to sue?
Written lease + roommate agreement: 4 to 6 years. Oral agreement: 2 to 4 years. Property damage: 2 to 4 years. Each unpaid month is its own claim with its own clock.
Will the landlord get involved?
Usually not. The landlord cares that the rent gets paid, not who pays it. Your contribution case against the roommate is between you and them. The landlord is not involved.
Can I combine multiple roommate claims?
Yes. One small-claims case can include unpaid rent + unpaid bills + property damage + deposit. Combine to avoid multiple court appearances.
