If you own the house, can you kick your girlfriend out? Not on your own, and usually not quickly. Once she has lived with you long enough to count as a tenant under your state’s law, you have to give her written notice to leave, and if she stays past that date, remove her through a formal eviction in court. Owning the property does not let you change the locks, cut the power, or put her things on the curb.
Is She a Guest or a Tenant?
Everything downstream depends on this question. A guest stays with your permission and you can revoke that permission at any time. A tenant has legal residency and can only be removed through the courts. There is no single test; a judge looks at the whole picture.
The factors that push someone from guest into tenant territory:
- Length of stay. Many jurisdictions treat a continuous stay of around 30 days as establishing residency, and some go as low as 7 to 14 days.
- Mail at the address. Bank statements, a driver’s license, or regular package delivery to your home all point toward residency.
- Money toward the household. Paying any part of rent, mortgage, or utilities strengthens a tenancy argument considerably.
- Belongings in place. Furniture, clothes, and personal items signal more than a visit.
- Official use of the address. Voter registration, driver’s license, or tax filings using your address all count.
If she has been living with you for months, gets her mail there, and chips in on bills, she is almost certainly a tenant in the eyes of the law, even with no written lease. The absence of a signed agreement does not mean the absence of rights. This is the first place people go wrong: assuming that because nothing was ever signed, they can simply tell her to go.
The Written Notice You Have to Give
Once she qualifies as a tenant, the process starts with a written notice to vacate. You cannot skip this step, and a verbal notice does not count. The notice states the date by which she has to leave and must be delivered in a way the law recognizes; personal hand-delivery or certified mail are the most reliable.
How much notice varies a lot by state. For a tenancy with no written lease, sometimes called a tenancy at will, 30 days is typical, but the range runs from about 15 days on the short end to as many as 90 days on the long end. Some states require longer notice once a tenant has been in the home for a year or more. Your local landlord-tenant statute or an attorney familiar with it will tell you exactly what applies.
Get the contents right. The notice should include your name, her name, the property address, the date you’re serving it, the date she has to be out, and a clear statement that you are terminating her right to live there. Keep a copy and document how and when you delivered it. A defective notice — wrong timeframe, wrong delivery method, missing information — can be thrown out in court, and you start over from zero.
If She Doesn’t Leave: Filing an Eviction
If she is still there after the notice date, the next step is filing an eviction lawsuit, sometimes called an unlawful detainer action, in your local court. This is the only lawful way to force someone out of a home they’ve been living in.
- File the complaint. You submit an eviction petition and pay a filing fee. Fees vary widely by jurisdiction.
- Serve the court papers. She has to be formally served with the lawsuit, usually by personal delivery or an approved alternative.
- Attend the hearing. Both of you appear before a judge. You’ll need to show that you gave proper notice and that she stayed past it. She can raise defenses, including improper notice, retaliation, or discrimination.
- Get the judgment. If the court rules for you, it enters a judgment for possession.
- Writ of possession. After the judgment, the court issues an order directing the sheriff or marshal to physically remove her if she still hasn’t left. Only law enforcement can carry out that removal.
Realistically, from serving the initial notice to a sheriff enforcing a writ of possession, the whole thing runs from about six weeks to several months. Court calendars are backed up, hearings get rescheduled, and a tenant can file motions that add delays. The process is slow on purpose, so that nobody gets thrown out of a home without a hearing.
Why You Cannot Just Change the Locks
This is the shortcut most people are tempted by, and it’s the fastest way to make things worse. Nearly every state prohibits self-help eviction: changing the locks, shutting off utilities, removing her belongings, or physically blocking her from getting into the home without a court order.
It does not matter that you own the house outright, that she has never paid rent, or that you are certain she has no right to be there. If you do it yourself, she can sue you for wrongful eviction and recover damages for temporary housing costs, damaged or lost property, emotional distress, and in many states statutory penalties on top of actual losses. Some states award double or triple damages for illegal lockouts. If the removal gets physical, criminal charges for harassment or assault are also on the table.
The rule is straightforward: only a judge can order someone out of a residence, and only a sheriff or marshal can carry that order out. The bill for a self-help eviction almost always runs higher than doing it the right way.
Why the Police Will Say It’s a Civil Matter
Many homeowners assume a call to the police will end the standoff. It usually won’t. If she has established residency, officers will classify the situation as civil and decline to remove her. Police handle criminal issues — trespassing, assault, property destruction — but a dispute over who is allowed to live in a home is for the courts.
Trespassing requires that the person was never authorized to be there or that authorization was clearly and legally revoked. Someone who has been living with you for months and has belongings in the house is not a trespasser. Officers know this and will tell you to go through the eviction process. The one exception is an active protective order barring her from the residence, which law enforcement will enforce immediately.
If Domestic Violence Is Involved
Standard eviction is the wrong tool when abuse is in the picture, on either side. If she is being abusive, you can petition for a protective order, sometimes called a restraining order, that can grant you exclusive possession of the home right away, even if she has otherwise established tenancy. Emergency protective orders can be issued the same day, often without the other party present. They typically last only five to seven days but can be extended through a full hearing into a longer-term order lasting months or years. Once served, she has to leave, and law enforcement will enforce it.
The reverse also matters. If you are trying to remove a girlfriend who is a victim of domestic violence, federal law gives her significant protections. The Violence Against Women Act prohibits evicting someone from federally assisted housing solely because they are a victim of domestic violence, dating violence, sexual assault, or stalking.1Office of the Law Revision Counsel. 34 USC 12491 – Housing Protections for Victims of Domestic Violence, Dating Violence, Sexual Assault, and Stalking Those protections cover public housing, Section 8 vouchers, homeless assistance programs, low-income housing tax credit properties, and other federally supported housing.2U.S. Department of Housing and Urban Development. Your Rights Under the Violence Against Women Act (VAWA) Many states extend similar protections beyond federally assisted housing. If domestic violence is a factor, talk to a domestic violence advocate or attorney before doing anything else.
Belongings She Leaves Behind
Once she’s gone, whether voluntarily or through eviction, she may leave property behind. You cannot just throw it out or sell it. Every state has abandoned-property rules, and ignoring them can leave you on the hook for the value of whatever you got rid of.
The general pattern across most states: send written notice to her stating that she needs to retrieve her belongings within a set period, typically 15 to 30 days. The notice should describe the property, say where it’s being stored, and give a deadline. If she doesn’t pick it up in that window, you can usually dispose of low-value items and must sell higher-value items at a public sale. Some states require you to hold the proceeds for a period in case she claims them.
Timelines, value thresholds, and procedures differ by state, so check local law before touching anything. In the meantime, store the property somewhere reasonable — a garage, spare room, or storage unit — and photograph its condition. Trashing an ex’s belongings out of anger is understandable and legally expensive.
When Her Financial Contributions Complicate Things
Regular financial contributions do more than strengthen her tenancy claim. If she has been paying part of the mortgage, funding renovations, or otherwise investing directly in the home, she may argue an equitable interest in the property itself. Those claims typically come as constructive trust or unjust enrichment arguments: that it would be unfair for you to keep the full benefit of her contributions. Courts don’t grant these automatically, and splitting the electric bill is nothing like paying half the mortgage for five years. But the risk is real, and it’s a reason many family law attorneys recommend cohabitation agreements that state clearly whether contributions are shared living expenses or ownership stakes.
Keep records of any payments she has made. If she has been paying a fixed monthly amount that both of you treated as rent, that history makes it easier for a court to find a landlord-tenant relationship, which means you have to follow eviction procedure exactly.
Common-Law Marriage Changes the Picture
If you live in one of the few states that still recognize common-law marriage, the breakup may not be a tenancy question at all. Roughly ten states — including Colorado, Iowa, Kansas, Montana, South Carolina, Texas, and Utah — along with the District of Columbia recognize some form of common-law marriage.3National Conference of State Legislatures. Common Law Marriage by State In those states, couples who hold themselves out as married and meet certain criteria may be legally married without a license.
That changes everything. Instead of an eviction, you’re looking at a divorce, with property division, possible spousal support, and the procedural protections that come with ending a marriage. If you’ve lived together for years in a common-law marriage state, called each other spouses, filed joint tax returns, or mixed your finances heavily, talk to a family law attorney before trying to remove her. The eviction process described here does not apply to a spouse.
When to Bring in a Lawyer
Plenty of people get through a breakup and move-out without an attorney. If she agrees to leave within a reasonable timeframe, put the agreement in writing, sign it, and count that as a good outcome. The legal process only becomes necessary when she refuses.
Get legal help when the situation includes any of the following: she has contributed to the mortgage and may claim a property interest; domestic violence is involved on either side; she’s threatening to sue or has already filed something; or you’re in a common-law marriage state with facts that could support a marital claim. An attorney who works in landlord-tenant or family law can tell you the exact notice period for your state, whether your specific facts require an eviction filing, and how to avoid the procedural mistakes that send people back to the start.
