Discovering an unauthorized person living in your property is a stressful and frustrating experience that can lead to significant financial loss and legal headaches. Getting them out requires a careful, methodical approach that protects your rights as a property owner. This guide provides a clear legal playbook to help you distinguish between different types of problem occupants and take the correct steps to lawfully regain possession of your property.
Know Your Terms: Squatter vs. Trespasser vs. Holdover Tenant
The first step in resolving an unauthorized occupancy is to correctly identify the situation. The legal path you must follow depends entirely on the occupant's classification, and using the wrong process can set you back weeks or months.
Trespasser
A trespasser is someone who enters a property without any permission or legal right. Think of someone breaking into a vacant unit or entering a fenced yard without consent. Trespassing is a criminal offense. Because they never had permission to be there, you can often involve law enforcement directly to have them removed.
Squatter
A squatter is a person who occupies a property without the owner's permission but may be attempting to establish a claim to live there. This is different from simple trespassing. Squatters often move into properties that appear vacant, abandoned, or neglected. In some jurisdictions, if a squatter occupies a property for a very long period under specific conditions, they can attempt to make a legal claim for ownership through a process called adverse possession. Dealing with a squatter almost always requires a formal civil court process, similar to an eviction.
Holdover Tenant
Also known as a tenant at sufferance, a holdover tenant is someone who once had a valid lease but continues to occupy the property after the lease term has expired without your permission. They are not trespassers because they initially entered the property legally. You cannot simply change the locks; you must follow your state's formal eviction process to remove them.
Unauthorized Occupant
This refers to a person who is living in the unit but is not on the lease. Typically, they are a guest of your official tenant who has overstayed the limits defined in your lease agreement. In this case, your legal action is directed at the tenant on the lease, not the unauthorized guest.
The First Step for Any Unauthorized Occupancy: Documentation
Before you take any action, your priority is to document everything. In any legal dispute, the person with the better records has the advantage. Do not delay, and do not rely on your memory.
What to Document
- Discovery: Note the exact date and time you discovered the unauthorized occupancy.
- Evidence: Take clear photos or videos of any signs of forced entry, property damage, or the occupant's personal belongings.
- Communication: Keep a log of every interaction. For verbal conversations, note the date, time, and a summary of what was said. Save all emails, text messages, or written correspondence.
- Notices: Keep pristine copies of any official notices you serve, along with proof of delivery (like a certificate of mailing or a photo of the posted notice).
- Reports: If you involve the police, get a report number and a copy of the official report.
Keeping all your documents, from the initial lease to photos and served notices, organized in one place is critical. A modern property management platform can act as a central hub for this evidence, ensuring nothing gets lost when you need it most.

Handling Trespassers: When to Call the Police
Because criminal trespassing is a public offense, your first call should be to local law enforcement. Unlike a civil eviction, the police may have the authority to remove a trespasser immediately.
Best Practices for Involving Law Enforcement
Be prepared for the call. When you contact the police (use the non-emergency line unless you feel there is an immediate threat), be ready to:
- Prove Ownership: Have a copy of the deed or a recent property tax bill on hand.
- State the Facts Clearly: Explain that you own the property and believe someone is on the premises without your permission. Use the term “trespasser.”
- Stay Calm: The police may be hesitant to get involved if the situation seems like a civil landlord-tenant dispute. If the person falsely claims they have a right to be there (for example, by producing a fake lease), the police may decide it is a civil matter and instruct you to go to court. While frustrating, this is common, and your next step is the civil eviction process.
The Legal Path for Squatters and Holdover Tenants: The Eviction Process
For anyone who is not a clear-cut criminal trespasser, you must use the civil court system to remove them. As of 2026, every state has laws protecting occupants from “self-help” evictions, and the penalties for landlords who break them are severe.
Do Not Use “Self-Help” Eviction Tactics
A self-help eviction is any attempt to remove an occupant without a court order. These illegal actions include:
- Changing the locks.
- Shutting off utilities like water, gas, or electricity.
- Removing the person’s belongings from the property.
- Harassing or threatening the person to make them leave.
Engaging in these activities will get you into serious legal trouble, including fines and potential lawsuits from the occupant. It will also destroy your credibility in court when you eventually file a proper eviction.
The Formal Eviction Framework
While specific terms and timelines vary widely by state and even city, the general legal process follows a set pattern. You must consult with a local attorney or legal aid service to understand your specific obligations.
- Serve Proper Notice: The first step is to deliver a written notice to the occupant. The type of notice (e.g., Notice to Quit) and the amount of time it gives the person to leave is dictated by local law and the specific situation.
- File an Eviction Lawsuit: If the person does not leave by the deadline on the notice, you must file a lawsuit with the local court. This is often called an “unlawful detainer” or “summary process” action.
- Court Hearing and Judgment: The court will schedule a hearing where both you and the occupant can present your cases. Bring all your documentation. If you win, the judge will issue a judgment for possession of the property.
- Writ of Possession: After the judgment, the court issues a final order called a writ of possession. This document authorizes a law enforcement officer, such as a sheriff or marshal, to physically remove the person and their belongings from your property. This is the only legal way to forcibly remove a non-paying or unauthorized occupant.
Special Case: The Unauthorized Occupant in a Leased Unit
What if your tenant moves in a friend or family member who isn't on the lease? This is a lease violation, and your actions should be directed at the official tenant you have a contract with.
Your Lease is Your First Line of Defense
A strong lease agreement is essential. It should include a clear guest policy that specifies how long a guest can stay before they are considered an unauthorized occupant. It should also have a clause prohibiting subletting without your written consent.
How to Take Action
Your legal recourse is with the tenant who signed the lease. You must serve them a formal written notice, typically called a “Notice to Cure or Quit.” This notice informs the tenant that they are violating the lease by housing an unauthorized person and gives them a specific period to “cure” the violation (i.e., have the person move out). If the tenant fails to comply, you can then proceed with filing for eviction against your original tenant based on the lease violation.
Proactive Strategies to Prevent Problems
The best way to handle a problem occupant is to prevent them from gaining access in the first place.
- Secure Vacant Properties: Regularly check on your vacant units. Ensure all doors and windows have strong, working locks. A property that looks maintained and secure is a less attractive target for squatters.
- Conduct Regular Inspections: Perform routine, properly noticed inspections of your occupied units. This allows you to verify who is living there and ensure the property is being maintained.
- Build a Strong Lease: Your lease is your most important tool. Work with a legal professional to draft an agreement with clear, enforceable clauses on guest limits, subletting, and the consequences of lease violations.
Your Next Step
Dealing with an unauthorized occupant is a test of patience and procedure. The law is specific and unforgiving of landlords who take matters into their own hands, so following the correct legal process is non-negotiable. Your immediate next step is to review your current lease agreement. Ensure it has a clear, legally compliant clause defining guest limits and the consequences of unauthorized occupants. If it doesn't, or if it's weak, make updating it your top priority.
