A provision in a deed or will that attempts to restrict ownership of the property -- for example, selling your house to your daughter with the provision that it never be sold to anyone outside the family. These provisions are generally unenforceable.

Funds, usually amounting to one or two months' salary, frequently offered by employers to workers who are laid off. No law compels employers to provide severance pay, although the employer may be legally obligated to do so if it was promised in a contract or employees' handbook.

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.'

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 valid contract in which a copyright owner authorizes another person or entity (called the licensee) to exclusively exercise one or more of the rights (or portion of such rights) that belong to the copyright owner under the copyright. The licensee is said to 'own' the rights granted in the license and is referred to as a copyright owner.

A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.

A law adopted by some cities or towns with desirable vistas -- such as those in the mountains or overlooking the ocean -- that protects a property owner from having his or her view obstructed by growing trees. View ordinances don't cover buildings or other structures that may block views.

A means of escaping an overly burdenome mortgage. If a homeowner can't make the mortgage payments and can't find a buyer for the house, many lenders will accept ownership of the property in place of the money owed on the mortgage. Even if the lender won't agree to accept the property, the homeowner can prepare a quitclaim deed that unilaterally transfers the homeowner's property rights to the lender.

A right to property that cannot be enforced in the present, but only at some time in the future. For example, John's will leaves his house to his sister Marian, but only after the death of his wife, Hillary. Marian has a future interest in the house.
