Final answer:
A spouse owning a parcel of land separately owns it in severalty, which means it is owned individually, without co-owners.
Step-by-step explanation:
If a spouse owns a parcel of land separately, the spouse is said to own it In severalty. Ownership in severalty means that the property is owned by one person in their own right, with no co-owners. This is in contrast to forms of co-ownership like joint tenancy, tenancy in common, or tenancy by the entireties, where multiple individuals hold ownership interests in the property.
