Relating to lawfully established units of land.

HB 3858 clarifies that leftover land (remainder) after legally creating a new land unit - such as a lot or parcel through subdivision or partition - is automatically considered a "lawfully established unit of land," even if not separately described in a deed or contract. This directly affects property owners, local governments, and land developers who divide property under Oregon’s land-use rules. The key mechanism adds a specific definition to Oregon law (ORS 92.010) stating that such remainders qualify as valid land units, preventing disputes over their legal status. The bill explicitly excludes units created solely for separate tax accounts, ensuring the change applies only to legally formed land divisions.
