The Squatter Risk Every Property Owner Should Know

The idea that someone could occupy your property without permission and eventually acquire legal ownership of it sounds like a scenario that belongs to fiction rather than property law. It is not fiction. It is an established legal doctrine called adverse possession, it exists in every common law jurisdiction in the world, and it has resulted in property owners losing assets that were legally and fully theirs simply because they did not take action quickly enough when unauthorised occupation began. At TheHouse48, this is a risk that every property owner, particularly those managing vacant land or investment properties remotely, needs to understand precisely and take seriously.

What Adverse Possession Actually Is and Why It Exists

Adverse possession is the legal mechanism through which a person who occupies property without the owner's permission can, after satisfying a set of conditions over a defined period, apply to the court for legal title to that property. The doctrine was not designed to enable theft. It originated from the principle that land should be put to productive use and that an owner who abandons effective control of their property for an extended period forfeits a degree of legal protection in favour of the person who has been actively using and maintaining it. In practice, it means that a squatter who occupies a property in a way that is actual, open, notorious, exclusive, hostile and continuous for the statutory period, which varies significantly by jurisdiction, accumulates a legal claim that courts can recognise. The statutory period in California is five years, in Florida it is seven years, in Texas the period has recently been shortened as part of 2025 anti-squatting legislation, and in Ohio it is twenty-one years. The requirements include continuous uninterrupted possession across that entire period, meaning any gap in occupancy resets the clock.

How the Problem Specifically Affects Property Owners

The category of property owner most exposed to adverse possession risk is not the landlord with occupied tenanted properties. It is the owner of vacant land, undeveloped plots, investment properties between tenancies and inherited properties that are not actively managed. Squatters are every landlord's nightmare in the specific sense that their presence goes undetected longest in these exact categories of property. A plot of land purchased for future development and not visited for two to three years, an inherited property in a different city that no one from the family occupies, a commercial property that has been vacant since the previous tenant left, all of these represent opportunities for adverse possession to begin accumulating without the owner's knowledge. The problem in Nigerian property specifically is compounded by the omo-onile dynamic discussed earlier in this series, where individuals with disputed or no legitimate claim to land physically occupy it and maintain presence in ways that create competing claims the owner must then litigate. Africa more broadly presents versions of this risk across jurisdictions where formal land registry systems are less comprehensive and where physical occupation carries significant practical weight in establishing claim.

What Has Changed in the Squatting Legal Landscape in 2025 and 2026

Several US states have significantly strengthened property owner protections against squatters in the past two years, reflecting growing concern about the scale of the problem in high-vacancy urban markets. West Virginia's legislation classifies squatting as criminal trespass, allowing law enforcement to remove squatters immediately after confirming illegal occupation. Indiana's Senate Enrolled Act 157 allows landlords to file an affidavit with law enforcement requiring officers to remove the squatter within 48 hours unless the squatter provides proof of legal right to be on the property. Texas passed Senate Bill 38 in 2025 creating a fast-track eviction process and removing squatters' claims on properties. New York clarified in its 2025 state budget that squatters who trespass are not tenants and cannot invoke tenant protections. These legislative changes reflect a legislative environment that is moving toward stronger property owner protection in many US jurisdictions, though the changes are not uniform and the underlying adverse possession doctrine remains intact in all 50 states.

The Nigerian Dimension of This Risk

In Nigeria, adverse possession as a formal legal doctrine operates differently from common law jurisdictions because the Land Use Act vests all land in the state and rights of occupancy can only be formally granted by the Governor. However, the practical risk of others occupying vacant land or property while the title holder is absent is documented and substantial. Cases where properties left unattended by diaspora owners or investors are occupied by third parties, who then resist removal on the basis of long occupation and improvements made to the land, have been litigated at multiple levels of the Nigerian court system. The practical protection in the Nigerian context follows the same fundamental principle: regular physical oversight of all property, verifiable documentation of ownership, engagement of a property manager where personal oversight is not possible and immediate legal action when any unauthorised occupation is detected rather than allowing it to continue in the hope that the occupant will eventually leave.

TheHouse48 believes that adverse possession and squatting risk are not theoretical concerns for remote property owners. They are documented real-world outcomes for owners who allowed the gap between their last visit and the discovery of occupation to grow too wide. The protection is not complex. It is consistent engagement with the property and immediate action when that engagement reveals a problem.
