A comprehensive legal term that describes the condition of being actually or potentially subject to a legal obligation.
Joint liability is an obligation for which more than one person is responsible.
Joint and several liability refers to the status of those who are responsible together as one unit as well as individually for their conduct. The person who has been harmed can institute a lawsuit and recover from any or all of the wrongdoers—but cannot receive double compensation, for instance, the full amount of recovery from each of two wrongdoers.
Primary liability is an obligation for which a person is directly responsible; it is distinguished from secondary liability which is the responsibility of another if the party directly responsible fails or refuses to satisfy his or her obligation.
