Learning Outcomes
After reading this article, you will be able to identify how the law protects pre-existing property rights in real property. You will understand the principles governing adverse possession, takings, and the limits on governmental interference with established property interests. You will be able to apply these rules to MBE-style questions and distinguish between valid and invalid state actions affecting property owners.
MBE Syllabus
For MBE, you are required to understand the legal mechanisms that protect pre-existing property rights against loss or interference. This includes the doctrines of adverse possession, the constitutional protection against uncompensated takings, and the limits on state regulation of property. For revision, focus on:
- The requirements for acquiring property by adverse possession and the effect on prior owners.
- The Takings Clause and the distinction between physical and regulatory takings.
- The limits on state and federal power to alter or interfere with vested property rights.
- The remedies available to property owners whose rights are threatened or infringed.

Introduction
Pre-existing property rights are protected by a combination of common law doctrines and constitutional guarantees. Owners are shielded from arbitrary loss of their interests, whether by private parties or government action. However, certain legal doctrines, such as adverse possession, can result in the loss of title if the owner does not act to protect their rights. The Constitution also limits the power of the state to take or interfere with property without just compensation.
Key Term: Pre-existing Property Right A legally recognized interest in real property that has already vested in an owner, such as title, leasehold, or easement, which is protected against later interference or deprivation.
Protection Against Private Interference: Adverse Possession
Adverse possession allows a non-owner to acquire title to land if certain conditions are met. This doctrine balances the interests of diligent owners against those who neglect their property.
Key Term: Adverse Possession The acquisition of title to land by continuous, open, notorious, exclusive, and hostile possession for the statutory period, resulting in the loss of the prior owner's rights.
Requirements for Adverse Possession
To acquire title by adverse possession, the possessor must:
- Enter and possess the land openly and notoriously.
- Possess the land exclusively and continuously for the statutory period (often 10–20 years).
- Possess without the true owner’s permission (hostile).
- In some states, pay property taxes (not always required).
If these requirements are met, the original owner’s rights are extinguished, and the possessor gains legal title.
Worked Example 1.1
A owns a vacant lot but does not visit or maintain it. B builds a fence and uses the lot as her own for 15 years, meeting all statutory requirements for adverse possession in the jurisdiction. A later discovers B’s use and sues to eject B.
Answer: B will prevail. A’s failure to act for 15 years allowed B to acquire title by adverse possession, extinguishing A’s pre-existing property right.
Protection Against Government Interference: The Takings Clause
The Fifth and Fourteenth Amendments prohibit the government from taking private property for public use without just compensation. This applies to both physical appropriations and certain regulations.
Key Term: Takings Clause The constitutional provision that bars government from taking private property for public use without providing just compensation to the owner.
Physical and Regulatory Takings
- Physical Taking: Direct appropriation or occupation of property (e.g., building a road through private land).
- Regulatory Taking: A law or regulation that deprives the owner of all economically viable use of the property.
If a regulation goes “too far,” it may be considered a taking requiring compensation.
Worked Example 1.2
A city enacts a law prohibiting all construction on a parcel of land to preserve wildlife, making the land worthless for any productive use. The owner sues for compensation.
Answer: The owner is entitled to compensation. The regulation denies all economically viable use, amounting to a compensable taking.
Limits on State Power to Alter Vested Rights
States cannot retroactively destroy vested property rights without violating constitutional protections. The Contracts Clause and Due Process Clause limit the ability of states to impair existing interests, such as easements or long-term leases.
Key Term: Vested Property Right A property interest that has become fixed and is not subject to being taken away without due process or compensation.
Worked Example 1.3
A state passes a law retroactively abolishing all private easements, including those already recorded and relied upon by property owners.
Answer: The law likely violates the Takings Clause and Due Process Clause, as it destroys vested property rights without compensation.
Exam Warning
State regulations that merely reduce property value are not usually takings. Only when a regulation deprives the owner of all economically viable use, or physically appropriates property, is compensation required.
Revision Tip
Always check whether a government action is a physical appropriation, a total deprivation of use, or a mere regulation. Only the first two are likely to be takings.
