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.'

An unforeseen and uncontrollable event that excuses a party to a contract from performing his or her duties under that contract. For example, a landlord can break a lease if the property she agreed to rent accidentally burns down before the tenants move in.

The building of a structure entirely or partly on a neighbor's property. Encroachment may occur due to faulty surveying or sheer obstreperousness on the part of the builder. Solutions range from paying the rightful property owner for the use of the property to the court-ordered removal of the structure.

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 form of property owned by a married couple. If a couple moves to a community property state from a non-community property state, property they acquired together in the non-community property state may be considered quasi-community property. Quasi-community property is treated just like community property when one spouse dies or if the couple divorces.

A doctrine that prevents a defendant from re-litigating an issue after it has been lost. For example, if your neighbor sues you for putting up a fence on his land and the court rules that your fence extends beyond your property line, you can't later file your own lawsuit seeking a declaration that the property line is incorrectly drawn.

A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

A person to whom a property right is transferred. For example, an assignee may take over a lease from a tenant who wants to permanently move out before the lease expires. The assignee takes control of the property and assumes all the legal rights and responsibilities of the tenant, including payment of rent. However, the original tenant remains legally responsible if the assignee fails to pay the rent.
