If you and a roommate are both on the lease, the landlord can usually collect the full rent from either of you. The roommate who left may still owe you, but that is a second problem. The first is keeping the rent paid and the lease out of default.
Joint and several liability
Most leases make every tenant responsible for the entire rent. If one stops paying, the landlord can demand all of it from the other, and an eviction for nonpayment hits everyone on the lease. A verbal deal between roommates about splitting rent does not change what the landlord can collect.
What roommates cannot do
- A co-tenant cannot evict another co-tenant. Only the landlord can start an eviction, and only through the court.
- Changing locks or removing a roommate's belongings can create legal trouble for you.
- A roommate who is not on the lease may still have tenant rights in some states, which means you may need a formal notice process to end their stay.
Steps to protect yourself
- Read the lease for rules on subletting, assigning, adding a roommate and early termination.
- Tell the landlord in writing that a roommate has left, so you are not accused of hiding it, and ask what the landlord will accept: a replacement roommate, a lease change or a release for the departing tenant.
- Pay your share and, if you can, the whole rent while you work it out, to avoid a nonpayment notice.
- Look for a replacement roommate and get the landlord's approval in writing. Some states have rules that let remaining tenants replace a departing one.
- Keep a record of what each person paid.
Getting money back from the roommate
If the departed roommate agreed to pay their share, you may be able to recover what you paid on their behalf in small claims court. Bring the lease, texts or a roommate agreement, and proof of payments. Without a written agreement, proving who owed what is harder but not impossible. See our guide to roommate agreements and house rules.
Security deposit issues
The deposit usually belongs to the tenants jointly, and the landlord returns it to them after move-out less lawful deductions. Agree in writing how to split it, and note that damage by one roommate can reduce what everyone gets back.
A hypothetical to see the money
Two roommates split $2,000 rent. One leaves in month four and pays nothing after. The remaining roommate owes the landlord all $2,000 each month because both are on the lease. If she pays for two months, she has paid $2,000 that her roommate owed. With a text saying he would cover his share and the payment records, she has a strong small claims case. Without any written promise, she still may be able to prove an oral agreement through bank transfers and messages.
Talking to the landlord
Landlords care about getting paid, not about who pays. A calm message that explains the situation, says you will keep the rent current and asks for options often gets a practical answer, such as approving a new roommate or releasing the departed one. Get anything the landlord agrees to in writing, since a verbal release is easy to dispute later.
Preventing this in future
A roommate agreement signed by everyone can set notice periods for leaving, how to split rent and deposits, who finds a replacement and what happens to damage. It does not bind the landlord, but it helps in small claims and prevents misunderstandings. See our guide to roommate agreements.
