The Legal Treatment of Adverse Possession of Government Land
Quick fact
In most common law jurisdictions, adverse possession cannot be used to claim government-owned land because the statute of limitations does not run against the sovereign unless the government expressly waives its immunity.
Why this is interesting
Imagine squatting on a plot of land for years and eventually becoming its legal owner—but what if that land belongs to the government? Would the same rule apply?

Understanding The Legal Treatment of Adverse Possession of Government Land
Adverse possession is a legal principle that allows someone who occupies another person's land without permission to eventually become the legal owner, provided the occupation is open, notorious, continuous, hostile, and exclusive for a statutorily defined period (e.g., 10–20 years). The idea is to encourage productive use of land and to prevent stale claims. However, when the land is owned by the government—federal, state, or local—the normal rules are altered. The government is generally immune from suit and from the passage of time in the same way as private owners. This means that even if a squatter meets all the common law requirements, they cannot claim title to government land. The rationale is that public land is held for the benefit of all citizens, and allowing private acquisition would undermine public resources and policy. Some jurisdictions have enacted specific statutes that create exceptions, but these are narrow and strictly construed.
A deeper explanation
The protection of government land from adverse possession is rooted in the doctrine of sovereign immunity—the principle that the crown (or the state) cannot be sued without its consent. In the context of land, this translates into the rule that statutes of limitation (which are the basis for adverse possession claims) do not run against the government. This is sometimes expressed as 'nullum tempus occurrit regi'—'time does not run against the king.' The government, as sovereign, is not bound by the passage of time unless it explicitly consents to be. Modern statutes may waive this immunity, but any such waiver is typically narrow and must be clear. Additionally, the public trust doctrine holds that certain lands (like submerged lands, parks, and roads) are held in trust for the public, making them even more protected. The practical effect is that a squatter on government land can be evicted at any time, even after decades, unless a specific law allows them to seek title. This strong protection ensures that public lands are not lost through the unauthorized occupation of a few, preserving them for current and future generations.
