Found a Squatter in Your Hawaiʻi Home? Here's What You Legally Can (and Can't) Do

Discovering someone living in a property you own — a home you inherited, a place between tenants, a house you haven't checked on in a while — is genuinely alarming. The instinct for a lot of homeowners is to march over, change the locks, and move their belongings out. In Hawaiʻi, doing that yourself is actually illegal, no matter how clearly the property is yours. Here's what the law actually requires.

Why you can't just remove them yourself

Hawaiʻi law prohibits what's called "self-help eviction" — changing the locks, shutting off utilities, removing someone's belongings, or physically forcing someone out without going through the courts first. This applies even when you're certain the person has no legal right to be there. Once someone has established residency in a property, however that happened, the law generally requires you to remove them through a formal legal process, not on your own. Ignoring this can expose you to real civil and even criminal liability — the wronged party in a self-help situation can end up being you.

The legal process to remove a squatter

• Formal notice. You generally need to serve the occupant with written notice before taking further action.
• File an unlawful detainer or ejectment action. This is a lawsuit asking the court to formally order the person removed.
• A court hearing and order. If the court rules in your favor, it issues an order directing the occupant to vacate, typically within a matter of days.
• Sheriff enforcement. If the person still doesn't leave, the order goes to the sheriff's department, which carries out the physical removal — not you.

This process realistically takes weeks, sometimes longer, particularly if the occupant contests it. It's frustrating when the property is clearly yours, but skipping steps to speed things up is exactly what creates legal risk for you.

Could a squatter actually gain ownership of my property?

This is the fear behind a lot of the anxiety around squatters, and the honest answer is: it's possible, but the bar is very high. Hawaiʻi's adverse possession law generally requires 20 years of continuous, open occupation if the person has "color of title" (some document that appears, even mistakenly, to give them ownership), or up to 30 years without one. For smaller properties, additional restrictions apply that make repeated adverse possession claims harder. In practice, this means a squatter discovered and addressed within a reasonable time is nowhere close to being able to claim ownership — but it's still a reason not to let an unauthorized occupant situation sit unaddressed for years, particularly on a vacant or inherited property nobody is actively monitoring.

Squatter, holdover tenant, or something else?

How you approach this can depend on the occupant's history with the property:

• A true squatter never had permission to be there at all.
• A holdover tenant had a lease that expired but never moved out — this may follow a somewhat different legal track than a squatter with zero prior relationship to the property.
• A family member or associate of a previous owner or tenant who simply stayed can complicate things further, especially with an inherited property where family dynamics are involved.

An attorney can tell you quickly which category applies and what process fits your exact situation.

What to do if you find someone in your property

• Don't confront them alone or attempt to remove them yourself. Document what you find — photos, dates, anything indicating how long they've been there.
• Contact the police to report it, understanding that removal itself is a civil legal process, not something officers can typically resolve on the spot.
• Contact a real estate or landlord-tenant attorney promptly to start the formal unlawful detainer or ejectment process.
• Secure the property to the extent you legally can going forward, and set up regular check-ins if it's vacant, to prevent this from happening again.

Getting the right help

The right legal process depends on the specific facts of your situation — how the person came to be there, how long they've occupied the property, and what documentation exists. I can't handle the legal removal process for you, but I can help you understand what you're dealing with and connect you with an attorney who handles this regularly, so you don't accidentally create legal exposure while trying to protect your own property.
