In a contract, a promise by one party not to hold the other party responsible if the other party carries out the contract in a way that causes damage to the first party.

In most states, these clauses are illegal in residential tenancies, but may be upheld in commercial settings.

A seller's taking advantage of a buyer due to their unequal bargaining positions, perhaps because of the buyer's recent trauma, physical infirmity, ignorance, inability to read or inability to understand the language.

A contract will be terminated if the buyer can prove unconscionability.

A legal doctrine stating that if a person receives money or other property through no effort of his own, at the expense of another, the recipient should return the property to the rightful owner, even if the property was not obtained illegally.

A way for two or more people to share ownership of real estate or other property. When two or more people own property as joint tenants and one owner dies, the other owners automatically own the deceased owner's share. For example, if a parent and child own a house as joint tenants and the parent dies, the child automatically becomes full owner. Because of this right of survivorship, no will is required to transfer the property; it goes directly to the surviving joint tenants without the delay and costs of probate.

A person or entity (such as a corporation) that must be included in a lawsuit in order for the court to render a final judgment that will be just to everyone concerned. For example, if a person sues his neighbors to force them to prune a tree that poses a danger to his house, he must name all owners of the neighboring property in the suit.
