What term is used for property ownership that involves more than one person?

The term "co-ownership" encompasses all forms of property ownership that involve two or more parties. It signifies that multiple individuals share ownership rights to a property, which can come with specific rights, responsibilities, and varying degrees of interest in the property. Co-ownership can include various arrangements, such as joint tenancy, tenancy in common, and tenancy by the entirety, each of which has its own rules and implications for ownership and inheritance.

Joint tenancy refers specifically to a type of co-ownership where two or more people hold equal shares in a property with rights of survivorship, meaning if one owner passes away, their share automatically transfers to the remaining owners. Tenancy by the entirety is a special type of joint ownership exclusively for married couples, providing certain legal protections that are not available in other ownership structures. Fractional ownership refers primarily to investment contexts where multiple investors own a share of a property, often used in commercial real estate or vacation properties, but it does not cover the broader concept of co-ownership in real estate law.

Thus, "co-ownership" is the most comprehensive and accurate term when speaking about property ownership involving multiple individuals.
