Idaho Adverse Possession Laws

While trespassing is a crime, adverse possession statutes provide loopholes in the law to account for certain situations in which a "squatter" or "continuous trespasser" may actually have a valid claim to the land. Under these laws, individuals who openly inhabit and improve an otherwise neglected piece of property may gain legal title to the parcel after a statutory period of time has passed (often 10 to 20 years). Adverse possession laws typically are used to help resolve confusion over property boundaries or to provide legal title in the absence of an official record of home ownership.

Adverse possession laws are rooted in common law and date back to the Roman Empire, where anyone who was in possession of any good without a title would become the rightful owner if the original owner failed to claim the property. Of course, stolen goods or land were not covered by this law in Ancient Rome.

Requirements for Claiming Property Under Adverse Possession Laws

State adverse possession laws all generally follow these six guidelines:

  1. Actual Possession - Physically present and actually using the property
  2. Continuous Period - Possession is not divided into periods, but continuous
  3. Hostile - No permission has been granted by the lawful owner
  4. Open and Notorious - No attempt has been made to hide from the lawful owner
  5. Exclusive Possession - Possession has been maintained by a single party
  6. Color of Title - Good faith belief that they are legally entitled to the property (a requirement in some states)
