Squatters and trespassers on your property

How the law usually works

The first legal question is often whether the person is truly a trespasser. Someone who entered by force, deception, or without permission may be a trespasser. But a person who was invited in, rented the property, received a key, paid rent, or previously had a tenancy may have legal protections even if the arrangement was informal or has ended.

A person occupying property does not usually become the legal owner simply by staying there. Ownership claims based on long possession—often called adverse possession, prescription, or possessory title—normally require many years of possession that is open, continuous, exclusive, and inconsistent with the owner’s rights. The requirements and exceptions differ substantially by jurisdiction.

Trespass may be a criminal offence, a civil wrong, or both. Criminal trespass laws may allow police to act, but police often treat an occupancy dispute as civil unless there is evidence of burglary, forced entry, criminal damage, threats, violence, or another offence.

Owners commonly have a right to seek possession through a court. Whether an owner can change locks, remove belongings, shut off utilities, or physically remove an occupant without a court order depends on local law. Self-help removal can expose an owner to claims for unlawful eviction, assault, property damage, or harassment.

If the occupant is a tenant, former tenant, lodger, or someone claiming a tenancy, the matter may need to proceed through eviction or possession procedures rather than ordinary trespass procedures. A court may require notice, an opportunity to respond, and a hearing before issuing a possession order.

Common processes

1. Check whether there is an immediate safety issue. People commonly contact emergency services when there are threats, violence, weapons, fire, forced entry in progress, or a risk to someone’s safety. Emergency services are generally not used simply to obtain a civil possession order.

1. Confirm ownership and the property’s status. Owners commonly gather the deed or land-register record, mortgage or insurance information, property-management records, and details about whether the property is residential, commercial, vacant, or part of a managed development.

1. Preserve evidence. Useful evidence may include photographs, video from lawful security cameras, messages, witness statements, utility records, signs of forced entry, and a dated timeline. People commonly avoid entering occupied areas without understanding the local rules, because doing so may create safety or evidence problems.

1. Ask the occupant to leave when appropriate. Some owners send a written demand identifying the property, stating that permission has ended, and requesting departure by a stated date. A demand is not the same as a court order, and its wording can matter if the occupant claims a tenancy.

1. Notify relevant authorities or service providers. Depending on the facts, people may report suspected burglary, criminal damage, utility tampering, or threats to police. They may also notify an insurer, property manager, homeowners’ association, or local authority. Police may document an incident without removing the occupant.

1. Use the correct court process. Owners commonly bring a possession, eviction, or unlawful-detainer claim. The papers usually identify the owner’s right to possession, explain why the occupant has no continuing right to stay, and request an order for possession. The occupant may file a response, raise tenancy or discrimination defenses, or dispute the owner’s evidence.

1. Use authorized enforcement. If the court grants possession, enforcement is commonly carried out by a sheriff, bailiff, or enforcement officer. Owners generally avoid personally removing people or belongings unless local law clearly permits it.

1. Secure and repair the property afterward. After lawful possession is restored, people commonly change locks, repair doors and windows, preserve important belongings under any required procedure, update insurance, and address utilities or safety hazards.

Deadlines and time limits

Deadlines depend on the legal route and location. Common examples include:

• A notice to leave may require anything from immediate departure to several weeks or months, depending on whether the person is a trespasser, tenant, lodger, or former tenant.
• A response to a possession claim may often be due within a short period—sometimes roughly 7 to 28 days—but the exact period depends on the court and method of service.
• Court listings and enforcement may take days, weeks, or months.
• Adverse-possession periods commonly range from about 5 to 30 years in the United States, with many states using periods in the middle of that range.
• England and Wales generally use a 10-year procedure for adverse possession of registered land, subject to notice, objection, and statutory exceptions.
• Canada and Australia use province-, territory-, or state-specific rules; periods may be around 10 to 20 years in some places, while some land-registration systems sharply limit or exclude such claims.

These are only typical ranges. People commonly confirm the applicable deadline with the court or a licensed attorney where they live, especially before changing locks, starting a claim, or responding to court papers.

Documents that usually matter

Documents and information commonly include:

• Title, deed, land-register, or property-tax records
• The purchase agreement, lease, licence, or written permission to occupy
• Rent receipts, bank records, utility bills, and messages
• Notices to leave and proof of delivery
• Police incident numbers or reports
• Photographs, videos, repair invoices, and witness statements
• Insurance policies and reports to the insurer
• Court forms, hearing notices, possession orders, and enforcement documents
• A timeline showing entry, communications, payments, damage, and attempts to resolve the matter

How it differs by jurisdiction

United States. Trespass, eviction, unlawful detainer, lockout rules, and adverse possession are mainly governed by state law. Notice periods and court forms can differ even between neighbouring states. Some states have expedited procedures for unauthorized occupants, while others require the ordinary eviction process. A person who appears to be a squatter may still claim tenant protections if there was permission or a rental agreement.

England and Wales. Squatting in a residential building is generally a criminal offence under section 144 of the Criminal Justice and Public Order Act 1994, although the law has important limits and does not turn every property dispute into a criminal matter. Commercial squatting is generally handled as a civil possession issue. For registered land, adverse possession is governed principally by Schedule 6 to the Land Registration Act 2002, including an application and notice process. Possession is commonly enforced through court bailiffs or High Court enforcement officers.

Canada. Property and landlord-tenant law is primarily provincial or territorial. Some jurisdictions limit or abolish traditional adverse-possession claims, particularly for registered land, while others retain narrower possessory-title rules. Residential tenancy statutes can apply even where the owner describes the occupant as a trespasser, so the facts about permission, rent, and the nature of the accommodation are important.

Australia. Land, trespass, tenancy, and adverse-possession rules are primarily state or territory matters. The relevant limitation periods and treatment of registered land differ. Residential tenancy tribunals or courts may have jurisdiction where an occupant claims a tenancy, while ordinary courts may handle other possession claims. Police powers and lawful self-help rules also vary.

When people consult a lawyer

Legal advice is especially useful when:

• The occupant claims to be a tenant, co-owner, family member, licensee, or purchaser
• Rent was paid, even informally
• The property is occupied by a child, vulnerable person, or someone claiming disability-related protections
• There are threats, violence, weapons, criminal damage, or suspected fraud
• You are considering changing locks, disconnecting utilities, removing belongings, or entering the property
• Court papers have been served
• The property is mortgaged, insured, jointly owned, inherited, or subject to an HOA or strata scheme
• The occupant has mentioned adverse possession or possessory title
• The property is in another country, state, province, or territory from where you live
