What can you sue your roommate for?

Pick the one that fits your situation. Each guide covers what you can recover, what evidence to bring, and how to file in your state.

All roommate disputes
Pick the one that fits your situation. Each links to a state-specific guide.
Unpaid rent
When you're both on the lease, the landlord can hold either of you fully responsible — and you can sue the roommate for their share. Bank records + text messages + the lease establish the case.
Unpaid bills + utilities
Shared utilities, internet, household supplies. The pattern of who paid what (Venmo records) plus the actual bills makes the case clean.
Moved out no notice
You can sue for their share of rent until you find a replacement. Document that you actively looked (screenshots of Craigslist or roommate-search posts) — courts won't let you collect indefinitely if you didn't try.
Damage or theft
Sue under negligence (they were careless) or 'conversion' (the legal name for taking your stuff). Photos + receipts + witness statements make the case.
Security deposit
When your roommate kept your share of the deposit the landlord returned. Bank record from move-in (you paid your share) + the landlord's refund record (made out to your roommate) establishes the case.
No written lease
Don't need one. Even without a written agreement, courts will recognize an 'implied contract' based on how you actually behaved — months of consistent Venmo payments establish what the agreement was.
Emotional distress
Pair this with another claim (unpaid rent, damage, etc.) for the strongest case. Therapy bills + provider notes + lost work back up the dollar amount.

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.

01
Unpaid share of rent.
When you're both on the lease, the landlord can hold either of you fully responsible — but you can sue your roommate for their share.
02
Unpaid utilities and shared bills.
Internet, electric, water, household supplies. The pattern of who paid what (Venmo, etc.) plus the actual bills establishes their obligation.
03
Rent owed after they moved out early.
Their share until you found a replacement. Be ready to show you actively looked (listing screenshots, screening texts).
04
Property damage and missing items.
Repair receipts, replacement cost, and photos. Taking your stuff is its own separate claim called 'conversion.'
05
Their share of the security deposit they kept.
The landlord refunded the deposit to one of you, and it never got split. Bank records settle the case.

01
Evicting your roommate.
If the landlord is on the lease too, eviction is the landlord's problem and goes to housing court, not small claims.
02
Getting back into the home if you've been locked out.
Lockout disputes need an emergency court order from housing court — small claims can't issue that.
03
Personal-injury claims.
Fights or accidents that caused medical bills go to regular civil court — you'll usually want an attorney.
04
Damages over the cap.
Multi-year unpaid rent or major property damage above $20,000 needs a higher court.

BUILD THE FILE

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.

FAQ

Roommate Disputes questions.

The questions roommates actually ask before filing.

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.
