If you want to kick out a roommate who is not on the lease, you almost always have to treat them like a tenant and use the formal eviction process: give written notice, and if they still won’t leave, take them to court. Once someone has been living in your place long enough to call it home, most states give them legal protections even without a signed lease, and trying to force them out yourself can cost you far more than going through the courts.
Guest or Tenant? That Question Decides Everything
The person on your couch is either a guest you can ask to leave or an occupant with tenant-like rights you have to evict. Courts don’t decide this by looking at the lease. They look at how the person has been living there.
Several things push a roommate across the line from guest to tenant:
- They pay any portion of rent, utilities, or recurring household costs.
- They receive mail at the address.
- They’ve been there long enough to establish residency. Some states set a threshold, often somewhere between 7 and 30 days; others let a judge weigh the whole picture.
- They keep personal belongings at the property — clothes, furniture, the things that signal this is where they live.
If your roommate has been there more than a couple of weeks, chips in on any bills, or gets mail at your address, assume they’ve acquired tenant-like rights. Telling them to pack up and go, and then trying to enforce it when they refuse, is where people get into trouble.
Can You File the Eviction, or Does Your Landlord Have To?
You’re the renter, not the owner. Whether you can file an eviction against another occupant depends on where you live. Some jurisdictions let a leaseholder file directly against an unauthorized occupant, subtenant, or guest who refuses to leave. Others require the landlord or property owner to bring the case.
Before you do anything, read your lease and talk to your landlord. Most standard leases limit who can occupy the unit and prohibit unauthorized occupants or subletting without written approval. If your landlord didn’t know about the roommate, tell them now. Disclosing the situation is almost always better than having it surface when eviction papers get filed. Your landlord may take the lead on removing the occupant, or authorize you to move forward on your own. Either way, keeping them in the loop protects your own tenancy.
Give Proper Written Notice
The first formal step is a written notice telling the occupant to leave by a specific date. Skipping or botching this step is the most common reason eviction cases collapse in court.
Notice periods vary. For occupants without a lease, most states require somewhere between 3 and 30 days, with 30 days being the common default for month-to-month or at-will arrangements. Some states allow shorter notice when the occupant has violated an agreement or engaged in illegal activity. The notice itself should include the occupant’s name, the property address, the date they must vacate, and a clear statement that you are terminating their right to remain.
How you deliver it matters as much as what it says. Acceptable methods usually include handing it to the occupant directly, leaving it with another adult at the property, or sending it by certified mail with return receipt. Taping it to the door is generally allowed only when the property is vacant or when other service methods have failed. Keep a copy and keep your proof of delivery. If service was done wrong, you start over.
Filing the Eviction Case
If the notice period expires and your roommate is still there, the next step is filing in court. Depending on your state, the case is called an unlawful detainer action, a summary possession proceeding, or a forcible entry and detainer case. The pattern is similar everywhere.
You file a complaint with your local court, usually a general sessions, small claims, or housing court, and pay a filing fee. Fees vary widely by jurisdiction but generally run between about $50 and $400. Many courts require formal service of the court papers by a process server or sheriff’s deputy, which adds another $30 to $150. If the roommate contests the case, the court sets a hearing.
Bring everything to the hearing: your lease, any written agreements with the roommate, records of any payments they made toward rent or bills, texts or emails showing you gave notice, and proof of service. The roommate can raise defenses, including that they were never properly served, that they have tenant rights you didn’t honor, or that you’re retaliating against them. Judges take these seriously, which is why every procedural step has to be done right.
If you win, the court issues a judgment for possession. That doesn’t mean the occupant is out that day. In most states they get a short window, often a few days to a week, to leave on their own before enforcement kicks in.
Getting the Sheriff to Enforce the Order
When a roommate still won’t leave after the judgment, you request a writ of possession, sometimes called a writ of restitution. This is a court order directing law enforcement to physically remove the occupant. Expect a separate court fee and a fee to the sheriff’s office to have it executed.
When the sheriff or marshal arrives, they oversee the removal and may change the locks or let you do so. If the occupant returns after being removed under a writ, that’s a criminal matter — call the police rather than handling it yourself.
From the initial notice to the sheriff showing up, the whole process commonly takes three weeks to three months, depending on court backlogs and whether the roommate contests. It’s slow by design. The law is built to prevent anyone from losing housing without due process, even someone who was never on the lease.
Do Not Change the Locks or Shut Off the Utilities
Changing the locks, cutting off utilities, tossing their belongings out on the sidewalk, or physically confronting them all feel faster and cheaper than court. They’re also illegal in nearly every state, and the consequences hit you personally, not your landlord.
On the criminal side, illegally locking someone out or shutting off their utilities can bring misdemeanor charges, fines, probation, and in some jurisdictions up to six months in jail.
The civil exposure is often worse. An occupant who’s illegally removed can sue, and the damages state laws provide tend to be generous. Depending on the state, a court may award the occupant actual damages (temporary housing, lost belongings, related expenses), statutory multipliers of two to three times actual damages, or a flat minimum regardless of what they actually lost. Some states also require you to pay their attorney fees. In a few states, statutory penalties alone can reach $5,000 to $10,000 per violation. A self-help eviction can easily cost more than the months of rent you were trying to save by skipping court.
Your Own Tenancy Is on the Line
An unauthorized occupant is a risk to you, not just to them. If your lease bars unauthorized occupants and your landlord finds out, they can issue you a notice of lease violation, and if the situation isn’t resolved, begin eviction proceedings against you as the leaseholder.
You also remain financially responsible for what happens to the unit while the roommate is there. If they damage the property, the landlord looks to you and your security deposit for recovery, not the person who wasn’t on the paperwork. As the leaseholder you carry that liability whether you caused the damage or not.
This is another reason to bring the landlord in early. Landlords have clear standing to file eviction proceedings everywhere, which sidesteps any question about whether you can bring the case yourself. Some will take the whole process off your hands once they learn about the unauthorized occupant, since they have their own interest in who lives on their property.
What to Do With Their Belongings
Once the roommate is out, you may find things left behind. Don’t throw them away. Most states require you to give the former occupant written notice and a reasonable window to reclaim their property before you can dispose of it. That window is typically at least 7 to 10 days, sometimes longer.
During the waiting period, store the property with reasonable care. You don’t have to pay for a storage unit, but you can’t deliberately destroy or damage it either. If they don’t claim it in time, state law dictates what happens next: some states let you sell the items and apply the proceeds toward money owed to you, others allow disposal after the notice period. Prescription medications and medical equipment often have longer storage requirements.
Document everything. Photograph the items, send the notice by certified mail, and keep records of when you sent it and when the deadline passed. If they later claim you destroyed valuable property, your documentation is the defense.
Two Situations That Change the Timeline
If your roommate files for bankruptcy while the eviction is pending, federal law triggers an automatic stay that pauses the case. If you already have a judgment for possession before the bankruptcy filing, the stay generally doesn’t block enforcement. Otherwise you may need to ask the bankruptcy court to lift the stay, which judges typically grant, though it can add weeks to the process.
If the roommate has committed domestic violence, dating violence, sexual assault, or stalking against you, faster options may exist. Many states have expedited procedures or emergency protective orders that can remove an abusive household member more quickly than a standard eviction. If you’re in immediate danger, contact law enforcement first — a restraining order or order of protection can force the person to leave regardless of tenancy status, and violating that order is a criminal offense. If you live in federally assisted housing, the Violence Against Women Act provides additional protections, including the ability to remove the abusive household member from the lease while other residents stay.
