Which of the following refers to ownership by one person?

Ownership by one person is referred to as severalty. This term specifically denotes that a single individual holds the property title independently, free from any shared ownership or claims by others. In severalty, the individual has full control over the property, allowing them to make decisions regarding its use, sale, or transfer without needing to consult co-owners.

Other forms of ownership, such as tenancy by the entirety, community property, or tenancy in common, involve multiple parties and shared interests. Tenancy by the entirety is typically limited to married couples, creating a form of joint ownership with rights of survivorship. Community property refers to a system in which spouses jointly own assets acquired during their marriage. Tenancy in common involves two or more individuals owning a property together, where each party holds a distinct, divisible share. None of these options represents sole ownership, making severalty the appropriate term for ownership by one person.
