If your roommate signed the same lease you did, you cannot kick them off the lease on your own. Kicking a roommate off the lease is something only the landlord has legal power to do, because eviction is a remedy landlords use against tenants, not one tenants use against each other. Your realistic paths are getting the landlord to act, negotiating a voluntary departure and lease amendment, or waiting for the term to end. The one situation where you do have direct authority is if your roommate is actually your subtenant rather than a co-tenant, and that distinction changes everything.
Why a Co-Tenant Can’t Evict a Co-Tenant
When both names sit on the same lease with the landlord, you and your roommate hold equal occupancy rights under the same contract. A court will not grant you an eviction order against someone whose legal position on that lease matches yours. No amount of frustration, missed rent payments to you, or bad behavior around the apartment changes that fact. Eviction paperwork filed by a co-tenant gets dismissed.
That leaves three real options: ask the landlord to pursue eviction for a lease violation, negotiate a voluntary exit and get the lease amended, or let the lease run out and not renew with the roommate included.
Don’t Change the Locks
Locking a roommate out, moving their things to the curb, cutting off the Wi-Fi, or making the apartment miserable enough that they leave are all forms of what the law calls self-help eviction. Every state prohibits it, and the prohibition protects anyone with a legal right to occupy the unit, including the co-tenant you want gone.
The consequences are real. Courts can award damages for each day the person was denied access, order you to pay for property you threw out, and even make you cover their temporary housing costs. Your roommate’s behavior is not a defense. Judges consistently treat the lockout as more serious than whatever set it off.
The Subtenant Exception
If only your name is on the lease with the landlord and your roommate pays rent to you under a separate arrangement, you are the master tenant and your roommate is your subtenant. In that structure, you function as their landlord, and you have the legal authority to initiate an eviction.
You still cannot skip the courts. The process looks the same one any landlord follows: proper written notice, the notice period runs out, and if the subtenant refuses to leave, you file an unlawful detainer action. Locks and curbside piles are illegal here too.
Read your lease before assuming which category you’re in. Two names on one lease signed with the landlord means co-tenants, and the subtenant path is closed. One name on the lease plus a separate agreement with the person you live with usually means you’re the master tenant.
Getting the Landlord Involved
Because only the landlord can remove a co-tenant, the fastest way forward is usually getting the landlord aligned with you. That takes one of two shapes.
A Voluntary Lease Amendment
If your roommate is willing to leave, the cleanest exit is a written amendment that removes their name from the lease. Everyone signs: you, the roommate, and the landlord. The landlord will likely want to see that you can carry the full rent alone before agreeing, and may require a replacement roommate if the numbers don’t work.
Get it in writing even when the departure feels amicable. A verbal “I’ll just move out” does not end anyone’s obligations under the lease. Until the document is formally amended, both tenants are still on the hook for rent and everything else the lease covers.
Asking the Landlord to File
If the roommate has violated the lease, the landlord may have grounds to begin eviction. The violations landlords typically act on are nonpayment of rent, significant property damage, illegal activity on the premises, and behavior that substantially disturbs other tenants. You can document the problem, report it, and press the case. The decision to file belongs to the landlord.
Landlords sometimes drag their feet. If the lease includes joint and several liability, the landlord can collect the full rent from you regardless of what your roommate does or doesn’t pay, so the financial urgency to remove a nonpaying co-tenant may not be there. Being direct about how the situation is affecting you as a paying tenant sometimes moves things along. Sometimes it doesn’t.
One risk to raise with the landlord before anything gets filed: depending on the lease structure and local law, an eviction action can target the whole tenancy rather than a single co-tenant. It’s possible to find yourself evicted alongside the person you were trying to remove. If the landlord seems unsure how to handle a partial eviction, that’s a signal to talk to an attorney.
What Your Lease Actually Says
Before you do anything, read the lease carefully. A few clauses shape your options directly.
- Joint and several liability. Most residential leases include this. Every signer is responsible for the entire rent, not just a share. If your roommate leaves or stops paying, you owe the full amount until the lease itself changes.
- Lease violation provisions. Language identifying specific behaviors that constitute grounds for termination gives the landlord a basis to act.
- Tenant modification procedures. Some leases spell out how tenants can be added or removed, including whether landlord consent is required (it almost always is) and what documentation is needed.
- Dispute resolution clauses. Some leases require mediation before legal action. Skipping a required step can hurt you later.
- Lease term and renewal. A fixed end date gives you the option of working with the landlord to exclude the roommate at renewal, avoiding eviction entirely.
What You’ll Owe If They Leave
Removing a co-tenant, however it happens, brings financial consequences that catch people off guard.
Joint and several liability is the big one. The moment the other person is off the lease, you owe the landlord the full rent alone. If you were splitting $2,000, you now owe $2,000. The landlord has no obligation to reduce rent because your household got smaller.
Utilities need attention. Accounts in the departing roommate’s name have to be transferred or reopened in yours before service gets cut. Security deposits are held for the whole tenancy and typically refunded only after everyone has vacated, which means sorting out your former roommate’s share is a private negotiation with no guaranteed outcome.
Legal costs pile up quickly if this reaches court. Most jurisdictions don’t allow you to recover attorney fees from the other tenant unless the lease or a roommate agreement specifically provides for it.
If Safety Is the Reason
The normal rules bend when a co-tenant is abusive. Under the Violence Against Women Act, housing providers in federally assisted programs (including Section 8, public housing, and low-income housing tax credit properties) have authority to bifurcate a lease, meaning they can remove the abuser from the lease without penalizing the victim, even when both names appear on it.1Office of the Law Revision Counsel. 34 USC 12491 – Housing Protections for Victims of Domestic Violence, Dating Violence, Sexual Assault, and Stalking
A victim cannot be evicted or denied housing assistance because of the violence they experienced. If the abuser was the only person eligible for the housing program, the remaining tenant gets a chance to establish their own eligibility, and if they can’t, the housing provider must give them reasonable time to find alternative housing.2U.S. Department of Justice. Violence Against Women Act Reauthorization Act of 2022 (VAWA 2022), Housing Rights Subpart
These federal protections cover assisted housing only, not private-market rentals. Many states have their own domestic violence housing laws that reach further, and some let victims break a lease early with documentation like a protective order, a recent police report, or a written statement from a medical professional. If safety is the issue, contact a local domestic violence hotline or legal aid organization before making any move. The usual rules about lease standing and eviction don’t work the same way when someone is in danger.
Stuff They Leave Behind
When a roommate moves out, they often leave things behind, and every state has rules for how abandoned property must be handled. You generally cannot throw away, sell, or donate their belongings the moment they’re gone.
Most states require written notice to the former tenant that property was left behind, followed by a waiting period before disposal. Waiting periods commonly run 10 to 30 days. During that window, the former tenant has the right to retrieve their belongings. Skip the notice requirements and you can be on the hook for the value of the items you tossed.
If anything left behind has real value, document it with photos and keep copies of any notices you send. Certified mail with return receipt is the safest way to prove delivery.
When It’s Worth Calling a Lawyer
Most roommate situations get resolved through some mix of negotiation, landlord involvement, and lease timing. A few justify the cost of counsel: illegal activity in the unit, threats or harassment, a landlord who won’t act on documented violations, or joint and several liability exposure that’s getting large. An attorney who handles landlord-tenant law can lay out your options in your specific jurisdiction. Local legal aid organizations also take housing cases for tenants who qualify based on income, which is worth checking before assuming help is out of reach.
