A commercial real estate lease in which the tenant regularly pays not only for the space (as he does with a gross lease) but for a portion of the landlord's operating costs as well. When all three of the usual costs--taxes, maintenance and insurance--are passed on, the arrangement is known as a 'triple net lease.' Because these costs are variable and almost never decrease, a net lease favors the landlord. Accordingly, it may be possible for a tenant to bargain for a net lease with caps or ceilings, which limits the amount of rent the tenant must pay. For example, a net lease with caps may specify that an increase in taxes beyond a certain point (or any new taxes) will be paid by the landlord. The same kind of protection can be designed to cover increased insurance premiums and maintenance expenses.

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 provision in a lease that absolves the landlord from responsibility for all damages, injuries or losses occurring on the property, including those caused by the landlord's actions. Most states have laws that void exculpatory clauses in rental agreements, which means that a court will not enforce them.

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.

An old legal term that is generally used to refer to real estate left to someone under the terms of a will, or to the act of leaving such real estate. In some states, 'devise' now applies to any kind of property left by will, making it identical to the term bequest. Compare legacy.

At trial, the initial questioning of a party or witness by the side that called him or her to testify. The major purpose of direct examination is to explain your version of events to the judge or jury and to undercut your adversary's version. Good direct examination seeks to prove all facts necessary to satisfy the plaintiff's legal claims or causes of action -- for example, that the defendant breached a valid contract and, as a result, the plaintiff suffered a loss.

A means by which one can legally take another's property without paying for it. The requirements for adversely possessing property vary between states, but usually include continuous and open use for a period of five or more years and paying taxes on the property in question.
