Frequently Asked Questions

Can I sue my roommate in small claims court?
Yes — you can sue a former roommate in small claims court for: unpaid rent or utilities they agreed to pay; their share of a joint security deposit that was withheld due to their damage; damage to your personal property; failure to pay their agreed share of shared household expenses; and failure to pay you back for shared expenses you covered on their behalf. The key is having some written record of the agreement.
Can I sue my roommate for unpaid rent?
To prove your roommate owes money, gather: any written roommate agreement or lease addendum; Venmo, Zelle, or bank records showing your payment history; text or email messages where rent amounts and due dates were discussed; shared utility bills and payment records; and photos of any damage they caused to the property. A lease signed by both of you showing the total rent is strong evidence of what each person owed.
Can I sue my roommate for damaging my stuff?
If a landlord withheld the security deposit because of damage your roommate caused, you can sue your roommate for their share of the withheld amount. You need the landlord's itemized deduction list, photos of the damage, and evidence that the damage was caused by your roommate rather than you. If possible, have witnesses (another roommate, a neighbor) who can testify about who caused the damage.
What if there was no written roommate agreement?
If your roommate is still living in the space and refuses to pay rent, your most urgent step depends on whose name is on the lease. If only your name is on the lease and you brought them in as a subletter, you can give written notice to vacate and, if they refuse, begin an eviction proceeding — which is separate from small claims. Small claims is for money you've already lost, not for forcing someone to leave. Contact your landlord first if both names are on the lease.
Can I sue a former roommate for taking my security deposit?
File in the small claims court for the county where the rental property is (or was) located. You do not need to know your ex-roommate's new address to file — you can file and then ask the court for guidance on serving someone whose address is unknown. Using social media or mutual friends to find an address, or hiring a process server who specializes in locating people, can help.
What if my roommate countersues me?
It depends on how your lease is structured. If you signed a joint and several lease, the landlord can pursue either tenant for the full rent — but that does not prevent you from suing your roommate for their unpaid share. Your roommate's agreement to pay half the rent (even verbal, supported by a pattern of payments) is an enforceable contract you can bring to small claims court.
