A provision in a contract that preserves the rest of the contract if a portion of it is invalidated by a court. Without a severability clause, a decision by the court finding one part of the contract unenforceable would invalidate the entire document.

Latin for 'that you cause to be done.' This is a court document that instructs a sheriff to seize and sell a defendant's property in order to satisfy a monetary judgment against the defendant.

A nonrefundable fee charged by a landlord when a tenant moves in. The fee covers the cost of cleaning the rented premises after you move out, even if you leave the place spotless. Cleaning fees are illegal in some states and specifically allowed in others, but most state laws are silent on the issue. Landlords in every state are allowed to use the security deposit to clean a unit that is truly dirty.

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.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.

A business guest, or someone who enters property held open to members of the public, such as a visitor to a museum. Property owners must protect invitees from dangers on the property. In an example of the perversion of legalese, social guests that you invite into your home are called 'licensees.'

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. The unfairness must be so severe that it is shocking to the average person. It usually includes the absence of any meaningful choice on the part of the buyer and contract terms so one-sided that they unreasonably favor the seller. A contract will be terminated if the buyer can prove unconscionability.

Property that carries a right to use a portion of a neighboring property. For example, property that benefits from a beach access trail across another property is the dominant tenement.

The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.
