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 guarantee about the quality of goods or services made by a seller, such as 'This item is guaranteed against defects in construction for one year.' Most express warranties come directly from the manufacturer or are included in the sales contract. If you want to hold the seller to an oral guarantee, it's best to get it in writing or have witnesses to the guarantee so that it doesn't come down to your word against the seller's if a problem arises.

Personal property that can be felt or touched. Examples include furniture, cars, jewelry and artwork. However, cash and checking accounts are not tangible personal property. The law is unsettled as to whether computer data is tangible personal property. Compare intangible property.

To take effect, or to benefit someone. In property law, the term means 'to vest.' For example, Jim buys a beach house that includes the right to travel across the neighbor's property to get to the water. That right of way is said, cryptically, 'to inure to the benefit of Jim.'

The power of the federal or state government to take private property for a public purpose, even if the property owner objects. The Fifth Amendment to the United States Constitution allows the government to take private property if the taking is for a public use and the owner is 'justly compensated' (usually, paid fair market value) for his or her loss. A public use is virtually anything that is sanctioned by a federal or state legislative body, but such uses may include roads, parks, reservoirs, schools, hospitals or other public buildings. Sometimes called condemnation, taking or expropriation.

A specific legal claim -- such as for negligence, breach of contract or medical malpractice -- for which a plaintiff seeks compensation. Each cause of action is divided into discrete elements, all of which must be proved to present a winning case.

A right to use property, acquired by a long tradition of open and obvious use. For example, if hikers have been using a trail through your backyard for ten years and you've never complained, they probably have an easement by prescription through your yard to the trail.
