Delaware Squatters’ Rights and Adverse Possession Laws

In Delaware, squatters’ rights come from the state’s adverse possession statute, which lets someone who occupies property openly and without permission for 20 continuous years ask a court to recognize them as the legal owner. Before that two-decade mark, a squatter has no ownership claim, but removing one still requires a court order. Owners who try to force the issue themselves face triple-damage liability under state law.

How Long a Squatter Must Stay Before Claiming Ownership

Delaware’s adverse possession statute bars a property owner from reclaiming land if they fail to act within 20 years of when their right to do so first arose.¹ A squatter who holds property for the full 20 years without the owner stepping in can petition a court to be recognized as the legal owner. The burden sits entirely on the squatter, who must prove every one of these elements:

Actual possession. Physically occupying and using the land, whether by living there, maintaining it, or making improvements.
Open and notorious use. The occupation has to be visible enough that a reasonable owner inspecting the land would notice. Hiding in a basement doesn’t count.
Exclusive control. The squatter treats the property as their own and doesn’t share it with the public or the titled owner.
Hostile occupation. The squatter holds the property without permission. The moment an owner grants permission, the hostile element disappears and the clock resets.
Continuous possession for 20 years. No meaningful gaps. Moving out for a year and returning starts the count over.

Delaware courts treat these claims skeptically, and most fail on the continuity requirement. Unlike California or New York, Delaware does not require the squatter to have paid property taxes during the occupation period.

When the 20-Year Clock Pauses

Delaware gives extra time to owners who couldn’t reasonably have known about or acted on the unauthorized occupation. Under Section 7903, if the rightful owner was a minor, mentally ill, or imprisoned at the time the squatter’s occupation began, that owner gets up to 10 years after the disability ends to take action, even if the standard 20-year window has already closed.²

The disability must have existed at the time the occupation started. If a property owner becomes incapacitated five years into a squatter’s occupation, that later-arising disability does not extend anything. If the disabled owner dies before the disability lifts, their heirs inherit the same extended timeframe the original owner would have had.² This matters most for family members who discover unauthorized occupants on property they’ve just inherited from a parent in long-term care.

Color of Title

A squatter’s position strengthens when they hold what’s called color of title: a written document like a deed or will that appears to grant ownership but is legally defective. The flaw might be an invalid signature, an incorrect property description, or a grantor who lacked authority to transfer the land. Delaware still requires the full 20-year occupation period regardless of whether color of title exists, but the document provides strong evidence that the squatter genuinely believed they owned the property.

Adverse possession does not wipe out existing mortgages. A squatter who successfully claims title inherits whatever liens are already attached to the property. To clear those encumbrances, the new title holder would need a separate quiet title action, and the lender gets every opportunity to defend its interest.

Removing a Squatter Through the Courts

The formal eviction process runs through Delaware’s Justice of the Peace Court using a summary possession action. This procedure is codified in the Residential Landlord-Tenant Code and is designed primarily for disputes where some prior relationship existed between the parties. The statutory grounds for summary possession include situations where a person unlawfully remains after a rental agreement expires, fails to pay rent, or breaches obligations related to use of the premises.³ Property owners dealing with a squatter who never had any rental agreement may need to pursue an ejectment action in Superior Court instead, which is a longer and more expensive route.

Filing the Complaint

The owner files a complaint at the Justice of the Peace Court. The filing fee is $45.⁴ The complaint and hearing notice must be served on the occupant at least 5 days but no more than 30 days before the scheduled hearing.⁵ A constable handles service to ensure formal notification. The complaint needs accurate property details matching the deed and evidence that the occupant has no legal right to remain.

Before filing, a police report for criminal trespass is worth making even if officers decline to physically remove the squatter. A squatter occupying a dwelling is committing first-degree criminal trespass, a class A misdemeanor.⁶ If the squatter has been there long enough to look like a resident, police may treat the situation as a civil matter and point you to the courts, but the report itself creates an official record that the occupation is unauthorized, which directly undermines the “hostile” element of any future adverse possession claim.

The Hearing and the Writ of Possession

At the hearing a judge weighs evidence from both sides. If the court rules for the property owner, it still cannot issue a writ of possession until the 5-day appeal window has expired.⁵ During those five days, the squatter can request a new trial before a panel of three justices of the peace. If the squatter appeals but doesn’t post a bond to stay the proceedings, the court can issue the writ anyway once the appeal period ends.

Once issued, the writ of possession directs a constable or sheriff to remove all occupants and put the owner back in control. The officer must give at least 24 hours’ notice and can only execute the removal between sunrise and sunset.⁵ Plan to change locks and secure the property the same day.

Why Changing the Locks Will Cost You

Delaware law makes self-help evictions expensive. If a property owner removes or excludes an occupant without a valid court order, that occupant can sue for triple the actual damages sustained or three times the daily rent for every day they were locked out, whichever amount is larger.⁷ The occupant can also recover court costs. Even when you’re clearly right on the underlying dispute, an illegal lockout hands the squatter a counterclaim that can dwarf whatever the property was worth in lost rent.

The statute also gives the ousted occupant the right to recover possession, meaning an owner who forces someone out without a court order may end up watching that person move back in under judicial protection. The court process takes time. It is the only path that doesn’t create fresh legal exposure for the owner.

Keeping Squatters Off Vacant Property

Most squatter situations start the same way: a property sits empty long enough for someone to move in. Inspect vacant land and unoccupied homes regularly. Consistent physical presence defeats both the “open and notorious” element of adverse possession and the practical reality of someone settling in unnoticed. Fencing and posted no-trespassing signs matter too. Entering property that is fenced or enclosed in a way clearly designed to keep people out elevates the trespass offense from a violation to an unclassified misdemeanor, which gives law enforcement more reason to act.⁶

Pay the taxes, keep the insurance current, and document every inspection. Twenty years is a long time, and most adverse possession claims fail because the squatter can’t prove uninterrupted occupation across that entire span. A paper trail of your own involvement with the property is the easiest way to guarantee they never can.
