Adverse Possession

property

Legal doctrine allowing someone to gain ownership of land by occupying it openly, continuously, exclusively, and hostilely (without permission) for statutory period (typically 5-20 years depending on state). Must be actual, visible, notorious, and adverse to true owner's rights.

Example: Person uses abandoned lot as garden for 15 years openly. In state with 10-year requirement, they may claim ownership through adverse possession if all elements met.

Reasonable Suspicion

criminal

Standard lower than probable cause but higher than hunch. Requires specific, articulable facts suggesting criminal activity. Allows: Terry stops (brief detention), pat-down for weapons if officer fears for safety. Cannot arrest or do full search based on reasonable suspicion alone - needs probable cause.

Example: Officer sees person looking in car windows at 3am in area with recent car break-ins. That's reasonable suspicion to stop and question. If person runs and officer sees bulge suggesting weapon, can pat down. But can't arrest or search pockets without more facts creating probable cause.

Probable Cause

criminal

Fourth Amendment standard requiring reasonable belief that crime was committed and suspect committed it, OR that evidence of crime exists in place to be searched. More than suspicion, less than proof beyond reasonable doubt. Required for: arrests without warrant, search warrants, vehicle searches.

Example: Officer smells marijuana, sees drugs in plain view, or receives reliable tip about specific criminal activity. That's probable cause. Mere hunch, anonymous tip without corroboration, or suspicion based on race/appearance is NOT probable cause.

Encroachment

property

When structure, improvement, or vegetation crosses property boundary onto neighbor's land. Examples: fence, building overhang, tree branches, driveway. May lead to: removal demand, easement negotiation, adverse possession claim if long-standing, or lawsuit for trespass/injunction.

Example: Your new deck extends 1 foot onto neighbor's property. Neighbor can demand removal. If you refuse, they can sue. Survey error is not defense. May need to remove deck portion, buy that strip of land, or negotiate easement.

Search and Seizure

criminal

Fourth Amendment protects against unreasonable searches and seizures by government. Generally requires warrant based on probable cause. Exceptions: consent, plain view, search incident to arrest, exigent circumstances, automobile exception, stop and frisk (with reasonable suspicion).

Example: Police knock on door, ask to search house. You say yes = consent (no warrant needed). If you say no, they need warrant or exception. Evidence from illegal search usually excluded at trial (exclusionary rule).

Warrant

criminal

Court order authorizing police action. Search warrant: allows search of specific location for specific items. Arrest warrant: authorizes arrest of named person. Must be based on probable cause shown in affidavit. Must describe with particularity what/who to search/seize. Exceptions allow warrantless searches in certain situations.

Example: Police get search warrant for 123 Main St to search for stolen laptops based on informant tip. Warrant must specify that address and those items. Can't search 125 Main St or seize items not listed unless plain view exception applies.

Property Boundaries

property

Legal lines that define the limits of land ownership. Established by deeds, surveys, and legal descriptions. Disputes resolved through surveys, title searches, or adverse possession claims. Property owners have exclusive rights within boundaries including airspace and subsurface rights (subject to mineral rights).

Example: Neighbor builds fence 2 feet onto your property. You can demand removal, seek damages, or if it stays 10+ years unchallenged, they may claim adverse possession in some states.

Easement

property

Legal right to use someone else's property for specific purpose. Types: utility easements (power lines), access easements (shared driveways), conservation easements. Can be created by deed, prescription (long use), or necessity. Burden runs with the land (transfers to new owners).

Eviction

civil
