Armstrong v. United States in Oregon Law

How Armstrong v. United States applies in Oregon: state-specific rules, key cases, and bar exam notes for Property.

State Approach

Oregon law recognizes the doctrines of equitable servitudes and adverse possession similarly to the federal level but emphasizes state statutes and case law in property disputes. Oregon courts afford significant weight to the intent of property owners and the public interest.

State Rule
In Oregon, a party claiming adverse possession must demonstrate continuous, open, and notorious use for a statutory period of 10 years while showing intent to possess the property as their own.
Significant State Cases

Harris v. Smith

The court ruled that adverse possession requires clear and convincing evidence of intention to claim the property in question.

Mowrey v. Korner

This case clarified that mere occupancy is insufficient; a claimant must also demonstrate exclusive possession of the property.

Mansell v. Henderlong

The court found that the elements of continuous use and intent can be demonstrated through actions of the possessor showing ownership-like behavior.

Comparison to Federal Law

Oregon's adverse possession requirements are mostly aligned with those articulated in Armstrong v. United States, particularly regarding the necessity of continuous and open use. However, Oregon law places an emphasis on statutory duration and the specific intent to possess, which may vary in interpretation from federal common law.

Bar Exam Note

Understanding the principles from Armstrong v. United States and how they apply under Oregon law is crucial for the property section of the Oregon bar exam, particularly in questions about adverse possession.

Practice Pointers
  • Always verify the statutory period for adverse possession in Oregon, which is 10 years.
  • Document the use of property to establish possessory claims effectively.
