If you and your roommate are both on the lease, the landlord can usually demand the entire rent from either one of you — not just your "half." It's called joint and several liability, and it's one of the biggest money traps in shared rentals. Here's how it works and how to protect yourself.
If your roommate stops paying, the landlord can come after you for the full month's rent. They don't have to chase your roommate first.
A roommate who leaves before the lease ends typically still owes rent until the lease term is up — or until the landlord releases them in writing. A verbal okay isn't enough.
When you're both on the lease, only the landlord can evict — you can't take a co-tenant to housing court. Money disputes between roommates go to small claims court instead.
Write down who pays what, who covers the deposit, and what happens if someone leaves early. Sign it. That gives you something to take to small claims court to recover money, even if the landlord won't help.
If only one of you is on the lease and the other pays that person, the lease-holder acts as the "landlord" for legal purposes — including notice and eviction. Read the lease before subleasing; many ban it without written permission.
