How to Evict an Adult Child from Your Home

Asking your grown child to move out is one of the hardest things a parent can do, and if they refuse to go, it can feel impossible. Take a breath: you have rights here, and there is a lawful, step-by-step way to handle it. This guide explains, in plain English, how to evict an adult child from your home without breaking the law or wrecking your safety. Because landlord-tenant and property law varies by state and even by city, treat this as general legal information, not advice for your exact situation.

First, Figure Out Their Legal Status

The law usually does not care that the person is your son or daughter. What matters is the legal relationship over the space they occupy. When an adult child lives in your home rent-free, with no lease, most states treat them as a licensee or a tenant-at-will rather than a true tenant. A licensee is simply someone you have given permission to be there, and that permission can be revoked. A tenant-at-will has a slightly stronger footing but still no fixed term.

The picture changes if your adult child has been paying you rent, contributing to the mortgage, or has a written or even verbal rental agreement. In that case many courts will treat them as a regular tenant, which means you must follow the full eviction process that applies to any renter. If money has been changing hands, do not assume you can skip steps. When the status is unclear, that uncertainty alone is a good reason to ask a local attorney how your state classifies the arrangement.

Never Use "Self-Help" Eviction

This is the most important rule, so read it twice. No matter how frustrated you are, do not change the locks, remove the bedroom door, shut off the electricity or water, take their belongings, or physically drag them out. These are forms of self-help eviction, and they are illegal in nearly every state, even when you own the home and even when the occupant is your own child.

Self-help can expose you to lawsuits, damages, and sometimes criminal charges. The fact that you pay the mortgage does not give you the power to enforce a removal by yourself. Only a court, through a sheriff or marshal carrying out a writ of possession, can lawfully force someone out. Your job is to go through the process; the state's job is to enforce it.

Step One: Serve Written Notice

The lawful path almost always starts with a clear, written notice to vacate. Even if you have told your child a hundred times to leave, courts want to see a dated written document. This notice ends their permission to stay and starts the clock.

• State a deadline. Many states require a notice period such as 30 days for a tenant-at-will, though it varies widely.
• Be specific. Include the address, the date, your name, and a plain statement that they must move out by a certain day.
• Keep proof. Deliver it in a way you can document, and save a copy for yourself.
• Stay factual. You do not need to explain or justify your reasons in the notice.

How long the notice must be, and how it must be delivered, depends entirely on your state and sometimes your city. Some places require personal delivery, some allow certified mail, and some accept posting on the door. Confirm the exact rule where you live before you serve anything, because a defective notice can force you to start over.

Step Two: File in Court If They Still Won't Go

If the deadline passes and your adult child is still there, you cannot remove them yourself. You file a case in court. Depending on your state, this is called an ejectment action (often used for licensees and non-tenants) or an unlawful detainer or summary process eviction (used for tenants). The court schedules a hearing, your child gets a chance to respond, and a judge decides.

If the judge rules in your favor, the court issues a writ of possession. A sheriff or other officer then carries it out and physically removes the occupant if needed. This is the only legal way to force someone out of your home. It takes time and patience, but it protects you from liability.

Does It Matter That They Just Turned 18?

People often ask how to evict an 18 year old from your home, as if a magic switch flips at that birthday. The honest answer is that turning 18 makes them a legal adult, so the parental duty to house a minor child generally ends. But it does not instantly turn them into a trespasser you can throw out. They have lived there with your permission, so most courts still expect you to give written notice and use the court process before removal. Age changes your obligations; it does not erase theirs to receive proper notice.

How to Evict a Child From a House in California and Other States

Rules really do differ from state to state, so the same situation can play out very differently depending on where you live. In California, for example, an adult child who lives rent-free is typically a licensee, and the path often runs through notice and then an unlawful detainer or ejectment action, with timelines set by state law. Other states use different notice periods, different court names, and different forms.

Whether you are wondering how to evict your son from your house in one state or how to evict an adult child in another, the core sequence is similar: confirm their status, serve proper written notice, and go to court if they refuse. The details that trip people up, such as exact notice lengths, which court handles the case, and which forms to use, are the parts you should verify locally. This is exactly where a short consultation with a landlord-tenant or housing attorney, or a call to legal aid, pays for itself.

Special Situations and Safety

Some circumstances add extra layers. Federal protections such as the Servicemembers Civil Relief Act (SCRA) can affect timing if your child is on active military duty. The Fair Housing Act may be relevant if a disability and a request for accommodation are involved. If there has been domestic violence in the home, laws like the Violence Against Women Act (VAWA) and various state statutes may shape what you can and cannot do. These are narrow but real, and a lawyer can tell you whether any apply.

If you feel unsafe at any point, your safety comes first. Call local authorities in an emergency, and consider a protective order if threats or violence are involved. That is a separate track from eviction, but the two can run alongside each other.

When to Talk to a Lawyer

You can often handle a simple, friendly move-out without legal help. But it is worth talking to a tenant-rights or landlord attorney, or contacting legal aid, when your child refuses to leave after notice, claims they are a tenant, has paid rent or the mortgage, raises a disability or domestic-violence issue, or when you simply are not sure which notice and court your state requires. Getting the first step right is far cheaper than fixing a mistake later. Laws also change over time, so confirm current rules before you act.
