In most states, false imprisonment is defined as the confinement of a
person without legal authority or the person's consent. Generally,
false imprisonment is accomplished by force or threat of force, and any
consent obtained by coercion or threat is not considered valid. False
imprisonment is often a misdemeanor and may also be the basis for a
civil suit for damages.
If someone wrongfully prevents someone
else from leaving a room, a vehicle, or a building when that person
wants to leave, this is false imprisonment. This can apply to family
members if the person desiring to leave is an adult. Years ago when
"deprogramming" was in style, several parents and family members were
prosecuted for false imprisonment for confining adult children. Spouses
have no legal right to confine each other either.
