How to Evict a Squatter in Washington State: Legal Steps and Options

Meta description: Learn how to remove a squatter in Washington State, when police may help, how unlawful detainer court works, and what property owners should avoid.

Finding someone living on a property without permission can be alarming, but removing that person improperly can create legal and safety risks. Washington has a process that may allow law enforcement to remove certain unauthorized occupants, and court proceedings remain an option when the person’s legal status is disputed. The right approach depends on the facts, including whether the person ever had permission to live there. This guide explains how to evict a squatter in Washington State, what evidence to gather, and why self-help removal is risky.

What Counts as a Squatter in Washington State?

“Squatter” is a common term, not a complete legal classification. It generally refers to someone occupying property without the owner’s permission and without a valid lease or other legal right to stay. The person’s history at the property matters: someone who entered without consent may be treated differently from a former tenant whose tenancy ended or a guest whose permission was withdrawn.

A person who once had permission to live in a home does not necessarily become a squatter as soon as the owner asks them to leave. The situation may instead involve a tenancy, a license to occupy, a family dispute, or another legal issue. If the occupant claims a lease, ownership, or some other right, the owner should have that claim assessed before choosing a removal process.

Washington’s residential landlord-tenant laws, including the Residential Landlord-Tenant Act (RLTA), may apply when an occupant is a tenant. Other statutes may govern a person who has no tenancy. Calling someone a squatter does not, by itself, establish which law applies.

Washington’s Law for Removing Certain Unauthorized Occupants

Washington law provides a route for law enforcement to remove certain unauthorized occupants from residential property without requiring the owner to first obtain a court order. The relevant statute is RCW 9A.52.105. It is intended for situations in which the person is an unauthorized occupant, not a tenant or former tenant with rights under landlord-tenant law, and does not have a legal ownership interest.

Under the statute, an owner or authorized agent may submit a signed, sworn statement requesting removal. The statement must address the circumstances required by law, such as the owner’s right to possess the property and the occupant’s lack of permission or legal right to remain. The statute also sets out conditions and procedures for law enforcement. Local agencies may explain their required forms and evidence.

This process is not a guarantee that officers will resolve every occupancy dispute on the spot. If the facts are unclear, the occupant presents a credible legal claim, or the matter appears to involve a tenant or former tenant, officers may direct the parties to court. Owners should not use the affidavit process to bypass tenant protections or settle a disputed lease.

Documents to prepare for law enforcement

Before contacting the local police or sheriff’s office, an owner can gather documents that clearly identify the property and explain the right to possess it. Requirements can vary by agency, so the owner should ask what it needs and how to submit the request.

• Government-issued identification and proof of ownership or authority to act for the owner.
• The property address and, where available, a parcel number or other identifying information.
• A signed statement describing when and how the occupant entered, whether permission was ever given, and why the owner believes the person has no right to remain.
• Relevant records, such as messages, witness information, photographs, or reports documenting unauthorized entry or occupation.
• Any lease, court order, or other document that may clarify the occupant’s status.

Statements to law enforcement must be accurate. A knowingly false sworn statement can create criminal and civil exposure. If there is a genuine dispute about a lease, former tenancy, or ownership, legal advice is especially important before submitting paperwork.

When a Court Case May Be Necessary

If the occupant does not qualify for removal under RCW 9A.52.105, or the local agency cannot resolve the situation, the property owner may need to file an unlawful detainer action. Washington’s unlawful detainer procedures are mainly in Chapter 59.12 RCW. An unlawful detainer case asks a court to determine who has the right to possession and, when appropriate, authorize removal.

The correct notice and procedure depend on the occupant’s legal status and the reason possession is being sought. Notice rules that apply to a landlord ending a tenancy may not fit a person who never had permission to occupy the property. Conversely, if the person is a tenant or former tenant, special landlord-tenant requirements may apply. Using the wrong notice can delay the case or lead to dismissal.

In a court proceeding, the owner generally must file the required documents, properly serve the occupant, and attend hearings. If the court rules for the owner, a writ of restitution may authorize the sheriff to restore possession. The owner should follow the court’s directions and coordinate any physical removal with the sheriff. A court order is not permission for the owner to personally force someone out.

Why notice and service matter

Notices and court papers must follow the applicable rules for content, timing, and service. A text message or informal demand may be useful evidence, but it may not satisfy a legal notice requirement. An owner should keep copies of every notice and record how and when it was delivered. For a complicated occupancy, a Washington attorney can identify the proper claim and reduce the risk of procedural errors.

Step-by-Step: How to Evict a Squatter in Washington

1. Confirm the property and the occupant’s status. Verify ownership or authority to act. Determine whether the person entered without permission, was invited as a guest, paid rent, signed an agreement, or previously lived there as a tenant. Do not assume the answer based solely on the occupant’s label.
2. Document the situation. Save messages and emails, note dates, photograph property damage from a safe and lawful location, and identify witnesses. Keep a written timeline of entry, requests to leave, and responses. Avoid entering an occupied home without legal authority.
3. Contact local law enforcement. Explain the facts and ask whether the agency uses RCW 9A.52.105 for unauthorized residential occupants. Ask for its affidavit or application requirements. Call 911 for an immediate emergency or threat; use the nonemergency number for a nonurgent property dispute.
4. Submit truthful documentation. Provide the sworn statement and supporting records requested by the agency. Be direct about any prior permission, rent payments, written agreements, or claims made by the occupant. Leaving out a material fact can undermine the request.
5. Use court if the matter is disputed or does not qualify. If officers cannot remove the occupant under the statute, consult a Washington landlord-tenant or real estate attorney about an unlawful detainer or other appropriate action. Follow the applicable notice, filing, service, and hearing procedures.
6. Coordinate any authorized physical removal. If law enforcement removes the occupant or a court issues a writ, follow the officers’ instructions. Arrange lawful access, secure the property, and handle belongings according to applicable law and agency guidance.

What Property Owners Should Not Do

Even when someone appears to have no right to occupy a property, an owner should not try to force the person out personally. Changing locks while the person is inside, removing doors or windows, shutting off utilities to make the home unlivable, threatening the occupant, or taking property can create serious legal problems. These actions may also increase the chance of confrontation or injury.

Washington law can impose consequences for unlawful exclusion or interference when a landlord-tenant relationship exists. Even where the RLTA does not apply, actions such as damaging belongings, entering unlawfully, or using force can raise separate civil or criminal issues. Owners should leave physical removal to law enforcement acting under the statute or to the sheriff carrying out a court order.

Owners should also avoid discarding an occupant’s possessions without determining what process applies. Belongings left behind after a lawful removal may be subject to specific handling, notice, storage, or disposal rules, particularly when the occupant is a tenant. Ask the relevant agency or an attorney how to secure and manage property lawfully.

Squatting, Trespass, and Adverse Possession Are Different

Unauthorized occupation may involve criminal trespass, but the facts and applicable statutes determine whether law enforcement can make an arrest or remove someone. A possession dispute is not automatically a criminal matter, and police may not decide a complicated civil claim at the scene. The removal procedure in RCW 9A.52.105 is distinct from a criminal prosecution and has its own eligibility requirements.

Adverse possession is also different from ordinary squatting. Under Washington law, a person generally must establish possession that is open and notorious, actual and uninterrupted, exclusive, and hostile to the true owner for the required period—typically ten years. Other legal doctrines and facts may affect the analysis. Merely occupying a home for a short time does not automatically transfer ownership, and an owner should seek legal advice if a long-term possession claim is raised.

How Long Does Removal Take?

There is no single timeline. A law-enforcement removal request may be quicker than a court case if the occupant clearly meets the statute’s definition and the agency can verify the required facts. Timing depends on the agency’s workload, the completeness of the submission, and whether the occupant contests the owner’s account.

An unlawful detainer case can take longer because it involves filing, service, court scheduling, and possible hearings. Delays may arise if service is disputed, the occupant raises a defense, or the case requires additional proceedings. Owners should avoid promises about a specific removal date and should not attempt to speed things up through lockouts or utility shutoffs.

Common Questions About Squatters in Washington

Can police remove a squatter without a court order?

Sometimes. RCW 9A.52.105 allows law enforcement to remove qualifying unauthorized occupants when the statutory conditions and documentation requirements are met. It does not apply to every person who refuses to leave. A tenant, former tenant, or person with a genuine legal claim may require a court process.

Can an owner change the locks?

An owner should not lock out an occupant who may have a legal right to possess the home or use a lock change as a substitute for lawful removal. After an authorized removal, the owner can secure the property in coordination with law enforcement and consistent with any court order.

Does a squatter get ownership after a few days or weeks?

No. Adverse possession requires much more than brief unauthorized occupancy. Washington’s general period is typically ten years, along with other demanding legal elements. The claim is fact-specific and does not automatically arise simply because an owner was away or the occupant stayed without permission.

What if the occupant is a former tenant?

A former tenant may still be covered by landlord-tenant statutes and court procedures, depending on the circumstances. The owner should not treat the person as a trespasser without checking the tenancy history, notices, and any court orders. Legal advice can help determine whether an unlawful detainer action is required.

Getting Help and Protecting the Property

For immediate danger, suspected break-ins in progress, or threats, contact emergency services. For a nonurgent unauthorized-occupant issue, contact the police or sheriff’s nonemergency line and ask about its process under RCW 9A.52.105. A local attorney can assess whether the occupant is a tenant, guest, trespasser, or claimant to possession and identify the safest next step.

After lawful possession is restored, owners can improve security by repairing entry points, changing access codes, documenting the property’s condition, and updating insurance records. Preventive measures should be taken only after the occupant has been removed through a lawful process. The central rule is to establish the person’s legal status, document the facts, and use law enforcement or the courts—not self-help—to regain possession.

Legal information is general and not a substitute for advice about a specific Washington property dispute. Statutes and local agency procedures can change; owners should verify current requirements with the relevant law-enforcement agency, court, or Washington attorney.
