Self-help, in the sense of a
legal doctrine, refers to individuals' implementation of their rights without resorting to legal
writ or consultation of higher authority, as where a
financial institution repossesses a car on which they hold both the title and a defaulted note. Individuals resort to self-help when they retrieve property found under the unauthorized control of another person, or simply abate nuisances (as by using sandbags and ditches to protect land from being flooded).
