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.

A determination of the value of something, such as a house, jewelry or stock. A professional appraiser -- a qualified, disinterested expert -- makes an estimate by examining the property, and looking at the initial purchase price and comparing it with recent sales of similar property. Courts commonly order appraisals in probate, condemnation, bankruptcy or foreclosure proceedings in order to determine the fair market value of property. Banks and real estate companies use appraisals to ascertain the worth of real estate for lending purposes. And insurance companies require appraisals to determine the amount of damage done to covered property before settling insurance claims.

A deduction allowed by the federal estate tax laws for all property passed to a surviving spouse who is a U.S. citizen. This deduction (which really functions as an exemption) allows anyone, even a billionaire, to pass his or her entire estate to a surviving spouse without any tax at all.

A right to use another person's real estate for a specific purpose. The most common type of easement is the right to travel over another person's land, known as a right of way. In addition, property owners commonly grant easements for the placement of utility poles, utility trenches, water lines or sewer lines. The owner of property that is subject to an easement is said to be 'burdened' with the easement, because he or she is not allowed to interfere with its use. For example, if the deed to John's property permits Sue to travel across John's main road to reach her own home, John cannot do anything to block the road. On the other hand, Sue cannot do anything that exceeds the scope of her easement, such as widening the roadway.

The loss of property or a privilege due to breaking a law. For example, a landlord may forfeit his or her property to the federal or state government if the landlord knows it is a drug-dealing site but fails to stop the illegal activity. Or, you may have to forfeit your driver's license if you commit too many moving violations or are convicted of driving under the influence of alcohol or drugs.

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.'

Land and the property permanently attached to it, such as buildings, houses, stationary mobile homes, fences and trees. In legalese, real estate is also called real property.
