A roommate wants to move out of a joint lease: what the landlord does
When one of several tenants on a joint lease moves out, the lease usually stays in force for everyone, and each tenant stays responsible for the full rent unless you sign a written release. Your choices are to keep the lease as is, add a replacement roommate after screening, or end the lease and write a new one. Handle the deposit and the paperwork at the same time.
Who owes what after one person leaves
Most joint leases make each tenant "jointly and severally" liable. That means the landlord can ask any one tenant for the whole rent, not only that tenant's share. A roommate who leaves still owes rent under the lease until the lease ends or a written release is signed. A verbal promise from the departing tenant to the others does not change your rights under the lease. Read your own lease, since some use different wording.
The remaining tenants may still want to keep the home. They will often ask to split the rent differently or find someone to take the departing tenant's place.
Your three options
| Option | What happens | Watch for |
|---|---|---|
| Keep the lease as is | The leaving roommate stays on the lease; the others pay the full rent | The leaving tenant remains liable, so they may press for a release |
| Replace the roommate | You screen a new person, who is added to the lease by an amendment | Apply your usual written criteria; the leaving tenant is then released |
| New lease for the remaining tenants | The old lease ends and a new one starts | Rent, terms and state notice rules may apply |
If the rest of the group cannot cover the full rent and you do not want to replace anyone, you can keep the lease and the departing tenant's liability in place. That is a business choice, and it is easier to keep calm and consistent about it.
Adding a replacement roommate
A new roommate must apply and be screened with the same written criteria as everyone else, so you do not treat applicants differently. See the checklist for tenant screening under FCRA. Once approved, sign a short lease amendment that adds the new tenant and, if you agree, releases the one who left, effective on a set date. Both the old and new tenants and all remaining tenants should sign.
Example a made-up three-person lease at $2,400 a month has Ana, Ben and Cruz. Ben moves out on March 31. The lease amendment, signed by all four people, adds Dee on April 1 and releases Ben on March 31. The rent stays $2,400, still paid by the tenants jointly.
The security deposit
The deposit belongs to the tenancy as a whole, not to one roommate. When one person leaves and the lease continues, you usually do not return a share now; the departing tenant and the others settle it between themselves, and the deposit stays with you until the whole tenancy ends. Put this in the amendment so nobody expects you to pay out a portion.
When the tenancy ends, return the deposit under your state's deadline and send the itemized statement to the tenants on the lease. In California, for example, Civil Code 1950.5 sets a 21 day return period. See deposit limits and return deadlines for how states differ.
Rent payments and the ledger
Decide whether you accept one combined payment or separate payments. A combined payment is easier to track. If you accept partial payments from individual roommates, record each one so you can show what was paid against the rent due. The guide on splitting rent among roommates shows how to set it up.
How DoorKeeping handles it
The lease and every amendment are stored on the unit, e-signed by every tenant, and the ledger shows each payment matched from your bank feed with the memo that identifies the unit. You can ask Claude or ChatGPT, "Who has paid toward 12B this month?" The amendment goes out for signatures only after you approve it.
Tenants pay your own bank, and the deposit stays in your accounts. It gives no legal advice about liability under your lease.

Questions
- Is a roommate who moves out still responsible for rent?
- Usually yes, until the lease ends or you sign a written release, because most joint leases make every tenant liable for the full rent.
- Does the landlord have to let a roommate out of the lease?
- No. A release is a choice, usually made when a screened replacement is added or the lease ends.
- Who gets the deposit when one roommate leaves?
- The deposit usually stays with the landlord until the tenancy ends. The roommates settle shares among themselves.
