In which state do I file a lawsuit against my roommate?


You would bring your case against your roommate in your current state as your roommate just moved out and they have not established jurisdiction in a new state yet. You would want to send them a demand letter first and demand the rent that is due due to their breach. If they do not agree to pay you then you would sue them in state court by filling out the complaint document and serving them.

For a Roommate breaking a lease, would I sue in the state the lease is in or the state the Roommate currently resides?

I understand this situation can be frustrating. In which state was the lease signed?

Florida

Is there a specific reason you are considering suing the roommate for breaking the lease?

They left with no notice and stuck me with the entire lease.

Is there anything else the Landlord-Tenant Lawyer should know before I connect you? Rest assured they’ll be able to help with your roommate breaking lease.

No
